That cannot *possibly* be a real test. It's one of those FauxNews flamebait things, right? Most of those questions do not make ANY sense.

I didn't think that test was particularly ridiculous. They were asking for the same kind of skills my kid and his class worked on last year, when he was in first grade. Is it weird to ask them whether a subtraction sentence involving one-digit numbers is true or false? Why?

The "part I know" language was unfamiliar to me, thus confusing, but it's clear from context what they're asking, and I assume this is the language in which subtraction was taught in class, which is why that's the language used on the test. Also, on question 12, I would call all four of the options addition sentences rather than subtraction sentences.

I dunno, they kinda makes sense if the lessons were taught a certain way. Take 5 pennies out of a cup containing 6 pennies answer how many are left. Take some blocks off a stack of blocks and how many are left. Seem to be about real concrete physical examples.

Question one has a confusing picture for the overthinking sort, 12 has a typo where 'subtraction' should be 'addition'. Beyond that, it looks like they're trying to teach kids with phrases that emphasize the way we write math is a language, a form of communication. I don't think that's a bad approach.

The answer is 1. It's clear from the other questions that one of the ways they learned subtraction was to talk about the "whole", and then some "part I know" of the whole, and then consider the question of how much of the whole is "missing," i.e. not the "part I know." Seems a perfectly reasonable way to approach subtraction. If there are 10 kids on my block and I've met 4 of them, there are 6 left to meet.

I, uh, don't see the problem here. This all seems very straightforward if the terms utilized have also been used in the teaching of these concepts to the students (and if that's not true then I'd question the relevance of the teaching in general toward the phrasing of tests more than the specific detriments of this piece of paper). Question 12 also has a typo, which confuses things.

The goal, which you may disagree with, is to introduce as few new words as possible when teaching math to children who potentially don't have great vocabularies or who might come from English Language Learner backgrounds. "Number sentence" is how you say "equation" without actually saying "equation." "Missing part" is "difference." I'm sure there are similar circumlocutions for words like "addition" and "sum."

I mean, don't most people who complain about never having learned math well because "it was taught poorly" complain about how abstract it was, how it's inhumanly difficult to make the connection between the number 6 and six of a thing, the fraction 1/2 and half of a pizza? Well, this is the language that actual teachers developed to talk about what numbers stand for and the stories people tell with numbers, while using an absolute minimum of words that kids may not know and could have trouble learning.

People asked for math instruction that uses age-appropriate language and connects math to concrete concepts. This is what that looks like.

Ugh. Valerie Strauss is one of the worst writers in American education. Note how that blog entry (which I realize someone else wrote - this is something she's doing a lot now) makes no reference to principles for or against the test in the mathematics pedagogy literature, just tells you someone trained in Calculus doesn't know this particular technique and that you must assume every test given in an American school is the result of some current demon (during GWB it was NCLB, now it's Common Core). I don't know that this is good, but outside some hyperventilating, I haven't been convinced its bad either.

I am kind of loving this; I like that there's a lot of reading required, and the kids are encouraged to draw to think through the answer (that might have been happening before Common Core; my little one isn't even 4 yet. But the amount of sturm I'm seeing on Facebook, etc about Common Core leads me to believe this is all mostly new). And also, this seems like the kind of thing you can't really drill.

The thing I'm really enjoying about the test is that it's not testing your ability to do arithmetic by hand, but to connect the concept of subtraction with both equation-based and picture-based representations of what's going on. I teach a lot of College Algebra, and I have had multiple students be amazed when I showed them how to multiply two single digit integers by drawing a rectangle divided into squares. A lot of students finish high school without an intuitive understanding of what arithmetic is, which means they will have a hard time developing an intuitive understanding of algebra. You have to get them when they're young!

I have third graders. This looks fine to me. I think it's the coffee cup in question one that's throwing everybody off; I'm not sure why they used a coffee cup, but for #1 (the only iffy one here, the rest seems fine) the instruction is to "find the missing part"; the part they know is 5, the whole is 6, so the missing part is 1.

What surprises me is the number of wrong answers this child had. Perhaps it's confusing when math questions are also word problems, but that's a useful life skill.

While you can certainly parse this test and get at the core idea being communicated by each question, it certainly is extremely awkward due to some really odd UI choices.

What the test seems to be really evaluating is your ability to extract the question out of a jumble of lines and word-things,*then* to apply a simple mathematical operation, rather than just testing the damn math.

I understand the value of the technique, EP, but I can't help but feel like it's a waste to use it on single digit integer equations. In my mind these should be regarded as "math facts" and memorized. I know that isn't the way it's done anymore, but I cringe when I see children reach for a calculator to answer, "What is 6 times 4?"

It took me a minute to understand that they were being taught to use a sentence to form the equation and to "sound it out", as it were. Once I grokked that, it became pretty obviously a test of subtraction abilities, and it was pleasantly concrete--much more so than a page of numbers stacked up.

And it kills me that my students don't know their times tables, but it also kills me that they don't know the first twenty square numbers, or double angle and half angle formulas, or a hundred other things. The fact that math education has to grapple with is that the average person has access to computers that can do literally any algorithmic mathematical process they ever learned almost instantly. When I'm doing research and I need to take an integral or multiply a bunch of polynomials together, I don't do it by hand, I let SAGE do it for me. I wish I knew the proper balance when it came to technology in the math classroom, so if anyone figures it out, let me know.

I homeschool and the math curriculum we use-- JUMP Math--teaches problems very much this. It is a very different vocabulary and approach than I learned in elementary school, which was 40 years ago. But because I've worked with my kids on this curriculum, the set-up of these problems was very comprehensible to me. I can't recall whether these specific skills were covered in first grade in our curriculum.

I wonder how the rest of the class did? It's easy to say, "This is ridiculous!" When your kid--or your friend's kid-- did poorly, but was that a typical outcome in the class? I wonder what the writer would have learned by interviewing the teacher.

I'm not necessarily in favor of early academics, I am really not in favor of graded tests in first grade, and I have not studied the Common Core well enough to have an informed opinion, but the article seems to me to represent a very uninformed opinion colored by a knee-jerk reaction shaped by prior biases.

Yeah, that's a really tricky question. The goal of "doing it by hand" is to demonstrate that the student actually has a conceptual understanding. Like, in your example with multiplying a bunch of polynomials, in a real life situation technology will save a ton of time and avoid silly arithmetic mistakes, but the person doing it ALSO needs to know that if they multiply a fifth order polynomial by a third order polynomial by a seventh order polynomial, they'd better get a fifteenth order polynomial or something went wrong. But at some point, the stuff that made sense to do by hand on a first grade subtraction exam becomes silly and irrelevant when the point of the assignment is to demonstrate your understanding of, say, Stokes' theorem.

I work with someone who simultaneously manages to be quite smart, but has zero instinct at all for realizing that "hmm, that result makes no sense, something went wrong somewhere, and maybe I should step away from the keyboard and think through the concept of what I'm trying to do". Someone will look at his numbers and say "oh, that's wrong" and he'll say "how do you knowwww?" and they'll say "because you multiplied hundreds times thousands and got 1.23*10^27, which doesn't make sense" and he comes back with more "but how do you

I am amused by all of the politicians and bureaucrats who love the Common Core and see it as the salvation of our nation. I suspect they are supporting standards that they have never studied. I wonder if they have ever read the details that ask first-graders to “compose and decompose plane and solid figures” and “to determine if equations of addition or subtraction are true or false.”I don't see what's wrong with either of those either. I guess they sound scary if you don't think about what they mean?

It seems to me that if the part of cookies you know is 5, and the whole of something unrelated to cookies is 6, then the part you don't know could be anything. The question depends on the picture, which could be interpreted as, 'If you have 5 cookies and some milk, what the hell are we asking you?' The correct answer would then be, 'Yes, the person who came up with these illustrations has been fired.'

This is not a Common Core math test. This is math homework. I do not have direct access to Pearson content so I don't know what specific product this is. But if this is 1st Grade, it is probably either *EnVisionMATH Common Core* or *Investigations in Number, Data, and Space for the Common Core*. You can look at them on the Pearson School website, which is a horribly incompetent piece of website design so I cannot link directly to these products.

These would be very early, nearly experimental Common Core materials, produced almost 5 years in advance of the general adoption targeted for 2015. They are only a small part of the picture, which includes "professional development" materials to help teachers deliver CC, test, and digital systems for testing and textbooks.

Disclaimer: I am a former employee of Pearson and I have nothing good to say about them. I currently work for their competitor (and occasional partner) which requests that I disclose my association with them. However, I don't think they want to be associated with me or my opinions so I will not identify them by name. Let me just say I am currently working on development of future Common Core products that directly compete with the one under discussion in this FPP, so I am a highly biased source.

No, this isn't how I learned math. I can see that teaching students a different language for dealing with math is bound to create difficulties when talking to other people who speak a different math language.

That said, this "part I know" terminology isn't the language of subtraction, it's the language of test-taking. You could use this "part I know"/"missing part" language to describe any operation on numbers. I'm also skeptical that teaching kids the wrong use of the word "sentence" has any benefit over teaching them the real word "equation".

The language is used sloppily on the test. Question 1 uses symbols in a manner that distracts from the meaning of the question. Question 12 asks for a "subtraction sentence", yet the correct answer demonstrates addition. Also, what are question 3's cubes?

Are there actual studies supporting this novel use of language, or is this just random theorizing on the part of the curriculum writers?

It took me a long time to figure out question 1 -- I basically had to go through the whole test and figure out the vocabulary they were using and then go back and solve it, but it seems like if the kids are being taught using those words, it probably makes a lot more sense to them than it does to me.

It actually reminds me a bit of an experience I had when I went to Brazil as an exchange student. We had these little tests every few weeks that covered a variety of subjects. I could generally parse the STEM subjects well enough to answer the questions, could barely even read the questions in subjects like Lit and Geography, but I fully expected to ace the English (as a second language) questions.

I fully expected it, right up until the very first question on the very first test was "Classify morphologically the underlined words in the following sentence." Fortunately it was multiple choice, so I figured out what they wanted based on the available answers, but as a native English speaker, the word 'morphologically' had certainly not ever been a part of my English language education. I could have written a 500 word essay on the themes in Merchant of Venice, but a question aimed at ESL students was potentially out of my reach because of an accident of vocabulary. The other students in my class had no issues with the question, because they'd also been in the class however many years before when classifying things morphologically had first been taught to them so they knew what the question was asking.

I'm not prepared to say this alleged test is poor, until I see it in context. There are many intermediate steps in teaching common core that do not seem logical until you consider that they are intended to *develop* analytic skills, they are not necessarily representative of the capabilities of students at this grade level. Here are the basic objectives of the Common Core Math program.

*Make sense of problems and persevere in solving them.*

Reason abstractly and quantitatively.

Construct viable arguments and critique the reasoning of others.

Model with mathematics.

Use appropriate tools strategically.

Attend to precision.

Look for and make use of structure.

Look for and express regularity in repeated reasoning.

I don't think this is ridiculous at all. As adults, we all take adding/subtracting for granted, but we forget that these "basic" things are fairly abstract in the beginning. My toddler can "count" to 20, but ask her how old Mama is and she'll say "eleven!" These methods had been used successfully in private schools long before they were adopted on a statewide level.

That being said, I'm really good at math. This would have driven me crazy as I child, because I "got" it almost immediately. But as a tool to teach the largest number of children possible the basics of math? Makes sense to me.

It's funny, I'm just working on going back to school to finish my degree. Admissions came back and told me I needed to take a placement test to see which math I needed. This inadvertently started a two-month odyssey where I had to do things like sit through an unskippable 8 hour "orientation" slideshow online with quizzes throughout to make damn sure I paid attention to where the library was on a campus I'd never even heard of, among other things, but then when I finished, I had to print out a PDF certificate and bring it in because of course they couldn't just update their records through the system I was using to take the test.

Likewise I had to take half a day off to go talk to an advisor to find out what test I needed to take even though I already knew what test I needed to take and had a letter from that very college stating it, but I went through the whole process and he said, "Oh, you have to take the math placement test" and I said "I know, that's why I'm here" and everyone acted like I was being an asshole.

But it's way less annoying this time around because I've been in the working world and the academic level of pointless bullshit just can't compete. It's good prep for those other poor bastards but I want to warn them they haven't seen anything yet.

I agree with what others are suggesting about the silliness of the language used here; there's nothing intuitive or immediate about "number sentence". Learning *what* that is and *how* to write one requires just as much tutelage as saying "equation". So why not simply state it in that manner, especially when the child will ostensibly learn the word "equation" in a couple of years when they advance in grade? This is complicated by the fact that the language utilized is "number sentence" in some areas, but specifically "subtraction sentence" in others, even, as in question 12, when the operation being performed is addition.

What I definitely**do** dig, though, are the pictures. Maybe they could be a little better done and more consistent, but it's definitely a bonus to have an immediate visual method of performing math to reinforce the words.

I'm one of the parents of a homework-crying kid. And I'll tell you it's not coming from the instruction the teachers are giving, it's coming from the fact that *I have no fucking clue how to help him with the homework*.

I can't tell you how many fights I've had over "here's how to make ten, son" vs "no, the teacher told us do to it THIS way". I've had homework*sent back with comments* letting me know as much. How the hell can I help him when I have no idea what they're trying to do? Yeah yeah, I know, this is the "OMG New Math" gripe of every parent.

And this was before Common Core, when we've spent the last two years struggling through UCSMP Everyday Math (fuck you, UChicago. And I'm a local). Even the teachers here now admit (off the record, of course) that Everyday Math was a bad way to go.

Now I've been informed that the third graders are spending 5-10 minutes a trying to catch up to Common Core because, in those last two years of heuristics and strategies and elaborate definitions for common mathematical terms,*they forgot to teach them their fucking addition and subtraction tables.*

All the awkward and strained phrasing around "part I don't know" and "missing part" seems designed to make 'x the unknown' less of a shock when kids get to algebra.

The idea of a symbol for an unknown quantity in an expression with numbers is apparently just too much for many people; many people I know, in fact.

It's very ordinary to us, but it sure took a long time to show up historically.

I suppose it's a little late to ask this, but perhaps somebody will explain #2 to me: I get the part about 8 jars, of which 6 have jelly and the rest have peanut butter. Yum! But why is the picture that goes along with this 6 cubes? Why does 8 go in the big box over a line of length 1? Why does the correct answer include two squiggles that look like sixes in the question-mark side of the box, next to the other 6 cubes?

If you have to have pictures, why not pictures of jars? Even the kid who answered this test, drew circles for the 7 balloons in problem 11. (Apparently he miscounted the number that were not red, after drawing "R"s in the two that are red, but whatever. At least he's aware that some balloons are round.)

There are eight jars in total, so the 8 goes over the line that encompasses all of them. (Nothing about it having length one.) Among that total are six jars of jelly (shown as cubes for some reason) and a question mark for the unknown number of peanut butter jars. The child has drawn in those jars as circles.

I don't know if I'm just younger than everyone else here or what, but this doesn't seem that far off from what I remember of first grade math. We used Unifix cubes, and I recall the phrase "number sentence" going around. I has the advantage of being analyzable by first graders. I had not the grammatical sophistication at that age to connect "equation" with "equals", but I could figure out that a "number sentence" had something to do with numbers. I even had some idea what a "sentence" was.

In later grades, "cubes" can also mean "six-sided number cubes," which in turn stand for the dreaded D word that textbooks for children aren't allowed to mention.

No, yes, of course, this is terrible graphic design, the visual metaphors are used in haphazard and confusing ways, and the resulting visual "aids" in fact conceal or misrepresent more information than they actually communicate.

And yes, there is no reason to believe that if children can learn the word "sentence," that they then cannot learn a small number of other school-related words like "equation."

I completely agree that making up new, "easier" words for children to use is pretty much uncleftish beholding.

Also, the production of test preparation materials for schoolchildren is a nightmarish gauntlet of bullshit that I have repeatedly written about on MeFi.

All that being said, these materials didn't fall out of the sky. They are examples of exactly the kind of materials that the public asked for, that columnists promoted, that parents praised, and so on.

You want more unsupported, long-debunked, entirely unscientific stuff for "visual learners" and "tactile learners"? Fine, here's a bunch of pictures and cubes and other crap! You think children can't think abstractly because Piaget said so 70 years ago? Sure, let's express every problem in terms of physical objects and people. You think words used in math are confusing and unnecessary? Let's replace them with heretofore meaningless strings of other common English words!

Everything on this test addresses something the lay public has been complaining about in regard to how math is taught to children. This is the better, more intuitive, more hands-on, more practical, more sensible, more reading-intensive, more reasoning-based math you wanted.

The test is really not straightforward, and while the core concepts of mathematics are independent of the vocabulary used to express them, some vocabularies are easier to comprehend than others and mathematics really depends on a strict, coherent vocabulary and setting out to make your meaning clear and also to ensure you don't make mistakes. These are abstract concepts, so you need precise language to articulate them.

There are large states that make very large textbook purchases from the major textbook publishers. Those states drive decisions about what's allowed into children's textbooks by the publishers and the instructional design companies they subcontract work to.

I guess a parent in Texas thought that "dice" is synonymous with "gambling," so the word is never used in textbooks. Also, cartoon animals in textbook pictures don't have genitals, and so on. As previously mentioned, modern textbook publishing is a vortex of bullshit.

If you google for "six-sided number cube," you will find lots of children asking for homework solutions on Yahoo Answers.

As an extra bonus, I showed her some simple algebra the other day (x+4=9, that kind of thing) and said that the x stood for the part you don't know, and she just grabbed the pencil, rewrote the equation as 9-4=x, and then looked at me and said "X is five." I gave her no other explanation, it just made perfect sense to her. Sure, it's different than how I learned math, but from my sample size of one, it seems to be doing a great job.

This is one of the most important aspects of Common Core. As I quoted previously from the CC standards:

One of my colleagues is always insisting that you can know all the math in the world, but if you can't communicate it to anyone with precision, your knowledge is useless. So at the upper levels, there is a huge emphasis on being able to write logical arguments in the form of proofs. Without the ability to write logical proofs, you can't even construct an argument that will convince yourself.

It does seem to me to boil down to "this is different and therefore it is bad." Well, the way you learned math as a kid? A lot of kids never really learned much math at all, eventually got passed through high school barely able too add and subtract, never had a lot of career options that required better math skills. The way we all did it as kids was not perfectly adequate, so something not resembling what we did as kids is probably a requirement for finding a way of teaching it that actually works.

I can't tell from the context of your comment whether this is sarcasm or actually meant to say, "Yeah, 5 year olds aren't ready to learn the word and concept of 'variable' as such."

In case it was sarcasm, though, I can tell you that the use of x, y, z in place of the unknown quantity appears as early as Grade 3 in some books. The term "variable" is taught at least at Grade 5, possibly Grade 4.

Many other countries' math standards start with algebraic concepts much, much earlier than we generally do in the U.S. There is really no reason not to lay a groundwork for "unknown quantity" in first grade.

It's more like 'why don't we start five-year-olds off with the most easy, understandable language possible and gradually phase them in to concepts like unknowns as necessary?'

This test makes it look like five-year-olds are being angled towards algebra before they even have a basic understanding of arithmetic. If the kid is having trouble with 4 + 6 (question 7), what the crap are we doing trying to subtly introduce things like unknown and known parts?

The thing is, teaching kids weird terminology will do them no favors when they enter a system that doesn't use that terminology -- which could be as soon as middle school.

My armchair layabout opinion is, simply, instead of offering problems like "2 + 3 = (blank)", just present them like "2 + 3 = X" Then when it comes time for Algebra, OMG, that 'X' they put all along, it can come somewhere other than the end MIND BLOWN.

3 - 2 = x

3 = x + 2

3x^2 + x - 1 = x^3 + 2x^2 + x - 1

x^3 - x^2 + x - 1 = x - 1

Now that we have our number sentence in cubic form, for any number sentence ax^3 + bx^2 + cx + d = 0, we have three roots:

x1 = -b/(3*a) + cbrt(-2*b^3+9*a*b*c-27*a^2*d + sqrt[4*(-b^2+3*a*c)^3+(-2*b^3+9*a*b*c-27*a^2*d)^2])/(3*cbrt[2]*a) + cbrt(-2*b^3+9*a*b*c-27*a^2*d-sqrt[4*(-b^2+3*a*c)^3+(-2*b^3+9*a*b*c-27*a^2*d)^2])/(3*cbrt[2]*a)

x2 = -b/(3*a) +(-1+i*sqrt[3])/2*cbrt(-2*b^3+9*a*b*c-27*a^2*d+sqrt[4*(-b^2+3*a*c)^3+(-2*b^3+9*a*b*c-27*a^2*d)^2])/(3*cbrt[2]*a) +(-1-i*sqrt[3])/2*cbrt(-2*b^3+9*a*b*c-27*a^2*d-sqrt[4*(-b^2+3*a*c)^3+(-2*b^3+9*a*b*c-27*a^2*d)^2])/(3*cbrt[2]*a)

x3 = -b/(3*a) +(-1-i*sqrt[3])/2*cbrt(-2*b^3+9*a*b*c-27*a^2*d+ sqrt[4*(-b^2+3*a*c)^3+(-2*b^3+9*a*b*c-27*a^2*d)^2])/(3*cbrt[2]*a) +(-1+i*sqrt[3])/2*cbrt(-2*b^3+9*a*b*c-27*a^2*d-sqrt[4*(-b^2+3*a*c)^3+(-2*b^3+9*a*b*c-27*a^2*d)^2])/(3*cbrt[2]*a)

However, note that our cubic number sentence is not quite of the desired form (x-1 on the rhs instead of 0). However, once we solve for lhs=0, we may manually seek the solution from the set such that it also satisfies rhs=0. After a few elementary number sentence stories, it can be shown using cubes that our final number sentence is that Faiza has (-1/2 + i*sqrt(3)/2)^3 purses remaining, which sounds very glamorous indeed.

I don't follow. Every unsolved equation involves known and unknown parts. All this structure is doing is articulating what the kid is mentally tallying no matter how the kid solves the problem: what do you know (I have four of a thing and six of a thing), what do you need to know (how many things do I have)?

Forget that sentence.

The emphasis should be on basic arithmetic, counting and the number system. Not on algebra. Instead of using terms like 'known part' and etc., questions should spell out what they're asking clearly and carefully so that these crucial foundations in arithmetic and counting can be laid. There's no point even considering algebra before then.

I don't get the hatred for "number sentence". Equations are sentences that (usually) involve numbers. Many of my students struggle with scientific writing because they don't get that equations are sentences. I would love it if students learned early that equations aren't this weird thing dropped on them from otter space, but just another way of using language. It seems reasonable to introduce the concept of an equation using words the kids likely already know. Is it really that hard for a parent to figure out what a number sentence is?

It also seems great to me that students start learning in first grade that math is about ways of representing knowledge (unknown part, representing numbers with squares to have a visual representation of arithmetic) instead of just algorithmic operations with numbers. This could help me avoid situations like the nightmarish conversation I had with a student who complained that the content of my college course "isn't really math" because "math is about numbers" but in class "everything on the board is letters".

Take any 4th grade class, give them a blank sheet of paper, and have them write out the times tables from 1 x 1 = 1 to 12 x 12. See how far they get in five minutes ( they *should* complete it without pause) , then go crawl into bed with a bottle of bourbon and cry...

The issue isn't that the kids aren't doing worksheets in class with this material. This issue is that if a kid is daydreaming while they should be doing the worksheet, the teachers are too busy with the next worksheet that they can't diagnose the deficiency at the time of occurrence, and if the kid is even remotely facile at 'gaming the system', then they'll be able to 'fake it' sufficiently for them to 'pass' the 'assessment tests'.

While being unable to multiply two single digit numbers without issue.

I suspect this 'falling through the cracks' and 'gaming the system' were things which only precocious children had to worry about in the past -- until the teachers got so overloaded... Now the cracks are so large it seems that ALL the kids are falling through them.

And this stuff about addition and subtraction and multiplication tables? Unless the public school in question is radically different from my kid's public school, they are teaching those too! My son has worksheets that look a lot like his, and he also has to do speed tests for addition and subtraction within 20; he has to get them all right within 3 seconds each in order to move on. There are obviously big controversies about curriculum but the people who design them are not idiots and they understand that computational fluency is a critical skill. Here, you can even look at the relevant section of the Common Core standards for 1st grade, it's right there, as well as pre-algebra skills like "Determine the unknown whole number in an addition or subtraction equation involving three whole numbers." which are tested on the worksheet in the link.

But I don't think it serves the children to rebrand all the content under a 'new' cognitive framework while missing basic skills.

this is one of the the actual common core standards that a 1st grader should meet.

And that's what that assignment seems to be testing for. Not at all confusing.

Part of "Common Core" is the idea that math and science should in integrated into the other topics too. So they read more nonfiction, and do graphs and charts in Social Studies. If the kids already know what a sentence is from reading, why

I just went to the open house at a prestigious private school in my neighborhood. They said they do TERC math, which I'd never heard of but pretty much sounds like what Common Core is trying to do. My immediate, defensive reaction was "I learned math the old-fashioned way, and I got a STEM degree, so WTF?" But then I looked at their alumni list, and there are tons of highly math literate people on the list. And when I asked them what happens if a kid has natural math aptitude and gets frustrated, they told me that the kid gets more advanced worksheets.

I mean, knowing that 6X5 = 30 can either mean that you understand multiplication, or that you have memorized that particular equation. Knowing that if you have six sets of five, or five sets of six, then you have thirty things total, is actually understanding multiplication. Even better is knowing you can break these things into 2X3X5 and get the answer that way.

For every story about a parent struggling to understand this vocabulary, I bet I can tell you another story about a kid who never understood their times table and cried over division. I actually remember trying to help my younger sibling with algebra, and she just wasn't getting it, despite knowing her times table. And then it dawned on me that she didn't really conceptually understand arithmetic. She only knew how to repeat it.

It's easy to mock things we don't understand. But the US has always done poorly at teaching math compared to other developed countries, so obviously what worked for you didn't work for everyone. There's a ton of evidence showing this does.

But that doesn't matter anyway. I could come up with a contrived "pronunciation" of a line of C code that happens to also be an English sentence. That doesn't make it a sentence.

They can, but sentences are not generally described with their topics used as adjectives directly modify the word "sentence." The phrase "*dog sentences" is just as silly. There are sentences about dogs, and that is exactly what people call them: "sentences about dogs." Nobody calls them "*dog sentences."

No, numbers cannot be expressed as a sentence. That's the purpose of having numbers, to express things that cannot be expressed well or at all in words. What would that even mean? What sentence is π, or the set of positive integers?

I don't give a fuck how they teach math. I do care that they they teach the actual language as it is spoken. The long history of children being forced to learn idealized, "more logical" forms of languages that don't correspond to the living language has been very destructive.

I attended first grade in 1981. We used the phrase "number sentence". For those that find this sort of thing difficult, that means this terminology was in use 32 years ago.* I remember sometime around, I don't know, third or fourth grade, encountering the word "equation" for the first time. "What's an equation?" "It's a number sentence." OK, that took two seconds. Like, I don't feel as though having the phrase "number sentence" in my brain took up such significant cognitive real estate that I was unable to immediately grasp the terminology "equation" and switch to it when we began using it.

FWIW I found the test, while ugly, completely straightforward and easy. Don't really get all the keening and wailing going on about it. (But I understand the "number sentence" debate even less.)

That's right! And this is why I am so excited, as a working teacher of mathematics, that kids are being exposed to the idea of "number sentence" early.

Here's the thing I try to convince my students of, that they have had trained out of them at an early age...

What you write down, when you write your work doing a problem, is *not* some random collection of jottings. It should be communication, just like if you were writing a paragraph! Everything you write down should be pronounceable, in English (or your language of choice). This means, in particular, that your

And the main verb? An equals sign.

Students insist on writing chains of equalities without the equals sign, just in consecutive rows or (worse!) just randomly next to each other, I presume because no one taught them that they should be reading what they write to themselves in their heads! But it gets in the way of actually understanding why they're writing down what they're writing.

Think about the sentence "the integral from 1 to 4 of x-squared integrated with respect to x is equal to the function one-third x-cubed evaluated from x = 1 to x = 4, which is equal to one-third of 4-cubed minus one-third of 1 which is equal to 63/3, which is equal to 21".

Ok, it's a bit of a run-on sentence, but the point is that the reason we use numbers and symbols in mathematics is *not* because there's some mystical thing we're doing with numbers that cannot be communicated with language, it's just that it's more compact notation. But the words

Taking a scenario like

"Ilana has 5 pieces of candy and Matilda has 7 pieces of candy. How much candy do both girls have together"

and being able to translate it into the number sentence

5 + 7 = 12

which is read "five plus seven is equal to twelve"---note the verb!

is a super-useful skill! It foreshadows the development of algebra: it's easy to transition into

"Ilana has 5 pieces of candy. How many pieces of candy does Matilda have if both girls have a total of 12 pieces of candy?"

which then turns into 5 + M = 12

Which then students are able to do (albeit with blanks, instead of named variables) in first or second grade! So you now have students engaging with really quite sophisticated mathematical concepts---functional notation! basic algebra!---in very early grades. Mathematics is *not* arithmetic. Drilling on basic arithmetic facts is not thinking mathematically. But what I am so excited about in many of these new curricula for early grades (Everyday Math, what I've seen of the Common Core materials) is that they *do* encourage actual mathematical thinking, even as they are teaching the basic arithmetic skills.

"2 + 2 = 5" or "3 and 5 hugged 11" are number sentences and given the meaning of the words "number" and "sentence" would appear to me to be just as valid as "I tripped and fell up into the sky".

They are not however equations, and it might be nice to not confuse children by using simple words incorrectly.

Notwithstanding my previous comments, I'm actually quite sympathetic to the "number sentence" locution, for similar reasons to those already mentioned here: it avoids combining a new and perhaps scary notation with a new and (perhaps already, by some pre-existing familiarity) scary term. More importantly, it does stress that this string of symbols can just be read out like a string of words can, and that this is an important step in learning how to read, understand, and manipulate such things. "Number sentence" might not be the best locution for the job, but it's a decent one, irrespective of whether the string of words produced is officially a grammatical sentence.

What drove this point home for me was when I was teaching an introductory math class for graduate students. Often one does stuff on the board then asks what the answer is, or students have a question about some specific mathematical issue. Either way, the student needs to be able to verbally communicate things like: (2+x^2)^3/3 or 3sin(x^2+1)/n dx. Even though most of them had had math through calculus, they hadn't learned how to actually speak these sorts of things, and doing so I think helped all of us not just to communicate, but to think better mathematically.

So, there are two issues here.

First: is an equation a sentence? (No, a number in and of itself, like pi or three, is a word, not a whole sentence. It is better to go back to the original framing and compare equations and sentences. Or what leahwrenn said, on preview.) If I knew Russian and wanted to write down "I am happy" in Russian (apologies, I do not speak Russian myself), would it not be a sentence if I wrote it in the Cyrilic alphabet versus if I wrote it in (some transliteration to) the Latin alphabet? What if I translated to a language that is (or has in the past been) commonly written in a non-alphabetic script, eg. either a consonant-based alphabet, a syllable-based one, or something even further from a "true alphabet" that is phoneme-based? Mathematical notation is just another script. It's not a phoneme-based alphabet; the symbols stand for full concepts much like more complex syllable-based alphabets. But mathematical notation is just a shorthand for (certain, technical) things that can be expressed in any full language used for everyday communication. Every mathematical symbol has a name that we can say aloud as a word, which has a meaning, and there are grammatical rules for how we string these words together. Mathematical notation was developed in part out of laziness - it's shorter and quicker to write 2 + 3 = 5 than two plus three equals five, and quicker to read if you are familiar with standard mathematical notation. In some cases this brevity obscures the meaning, and in some cases it can help clarify meaning, eg. by organizing the information presented in a long and complicated word problem. But yes, an equation is a sentence.

And one of the major causes of student frustration and difficulty as they get farther along in math that those of us who teach math see is students not understanding this connection very well. Some students will pick up on this idea implicitly, no matter how they've been taught basic arithmetic. But this is far from universal, and it's more helpful to teach people to think of mathematical notation in this way, as a parallel language, initially, because unlearning incorrect concepts is way harder than learning new concepts. So when students don't learn to make the sort of conceptual connections between things expressed in mathematical terminology and things expressed in their everyday language of communication (English, in the case of the FPP link) when they are first learning arithmetic, and instead take arithmetic statements and equations as disconnected facts to memorize that don't have any underlying structure or reason behind them, they form certain habits or approaches to learning math that are very counterproductive yet hard to unlearn and change later on.

They are not however equations, and it might be nice to not confuse children by using simple words incorrectly.

Technically, 2+2=5 is an equation. It satisfies mathematical grammar rules, and asserts that one algebraic expression is equal to another. It happens to be a false equation, under any standard set of arithmetic axioms, and thus just as valid an equation as "I tripped and fell up into the sky" is as a sentence. But it is an equation, just as "I tripped and fell up into the sky" is a sentence.

Second, is using the term "number sentence" any more or less obscure than using the term "equation"?

The argument seems to be that students will somehow naturally learn and understand precise technical terminology from the area of mathematics, or that the meaning of "equation" is not also something that students need to be taught, just as they would need to be taught the meaning of "number sentence"? Certainly "equation" is a more precise, technical term. This sort of precision in the terminology used to describe mathematical concepts is important farther along, when students get to subjects like calculus and beyond, or when they get far enough along in developing their mathematical (abstract/quantitative/logical) reasoning and argumentation (i.e. proof) skills that they need to worry about mathematical rigor. But describing the technical terminology of mathematics as less logical, more of a living language, as part of an all-encompassing knowledge base that won't distinguish between in- and out-groups, as avoiding jargon... while this point of view excites and pleases me somewhat as a mathematician, these are not the usual complaints levied against technical mathematical terminology. Students would have to learn a definition of equation just as they would have to learn a definition of number sentence. This seems equivalent to me.

Additionally, throughout mathematics education, we refine and add to the initial definitions of mathematical terminology and concepts that students are taught. (And there are some good reasons for this: empirically at least, when educators have attempted teaching mathematics carefully and rigorously from first principles, eg. the Bourbaki books, it hasn't been a particularly effective pedagogy.) So introducing the concept of equations as number sentences, then later adding the terminology "equation", is a quite minor addition to the amount of refinement that students will already experience.

Given that what an equation is has to be defined and taught to students, and involves telling students the requirement that the verb involved be "equals" (or any of it's variants, like "is"), adding a similar requirement to the definition of "number sentence" to exclude examples like "3 and 5 hugged 11" doesn't seem any more involved to me.

Math always involves jargon and neologism. "Quotient" is jargon. The goal is to choose *useful* jargon–useful in a pedagogical sense. People seem to be objecting to it here because it confuses them, reading it now. But learning it in these terms for the first time would be no more confusing than whatever other words might be used, and at the end, students will be less likely to think that a mathematical equation is somehow not exactly isomorphic to a declarative sentence. Sorry, but I think that's a fundamental misunderstanding of what mathematics *is*, and a lot more worrying than not knowing the multiplication tables.

I teach physics. A major predictor for success is familiarity and comfort with math as a language for expressing ideas. It is amazing how many students who see themselves as "bad at math" suddenly excel at physics once they realize that equations are just another way of writing down an idea. That understanding is what the "number sentence" construct is designed to instill.

You don't actually need to have that much practice with basic arithmetic, in this age of computers, to do higher math, which is more about how values relate and change than 7 + 4 = ?.

According to me. My point is that if you have to stop what you're doing to work out trivial 'math facts' when they're embedded n-levels deep in the problem you're working on, no-one did you any favors by letting you skip doing the actual difficult work of memorizing them. The 'context switch' from real problem solving to trivial arithmetic has a cost, too. And that cost adds up every time the context switch occurs.

I've been to math ed talks on similar topics, though not this exact topic. My guess would be that there's probably been several studies, maybe more given that the term "number sentence" has been around for 20 or 30 years according to some of the other comments in this thread, though probably not ideal clinical model studies with test groups and control groups and giant sample sizes and double-blind collection and analysis of results and all that, for the reasons that Apropos of Something mentioned, as well as for the reason that there's not as much grant money available for funding educational research as there is for research that is likely to have direct commercial or defense applications. We could check this by, eg. going to scholar.google.com and doing a search on number sentences, which returns a list of mostly relevant research articles, whose abstracts should all be publicly available for perusal.

And if you were thinking about the actual concepts, you'd realize not all word sentences are equations - we have a lot of different verbs. Actually, not all math sentences have to be equations either - you can have greater-than and less-than statements. (What are those usually called? Expressions?) I don't think there's anything confusing about saying number sentence. Maybe it will help some kids who just memorized and then forgot things actually grasp what's going on.

Even with resources, we haven't mentioned how insanely difficult it is to do random assignment in American schools. Kids are never assigned randomly to classes, no matter what districts say: principals and administrators and teachers all weigh in on where kids go. Then, there's no hope of blindness: it's pretty clear to everybody what the treatment is and what the control is. From there, teachers naturally talk, and kids in the control will get some percentage of the treatment, and you're totally screwed up.

What ed researchers are more likely to do as a result is use propensity score matching, a technique which tries to identify schools which are very similar to each other to function as treatment and control. Which works relatively well ... except, of course, it can only match on things we can and do measure systematically. For the reasons Nomyte identifies, you're also unlikely to push your treatment school into being guinea pigs as much as you look for a school with a high propensity score match that has already implemented the curriculum you're interested in. And in those environments, of course, level of participation in the treatment is all over the map.

So, long story short, we get close to experiments: but not without intrinsic ethical issues, enormous budgets we don't routinely have, and the caveats that tend to always accompany science that doesn't happen in labs.

From TFA: "There is no evidence that early childhood experts were consulted to ensure that the standards were appropriate for young learners." This refers specifically to these specific "college-ready skills" being so "backmapped." I'm sure that early education specialists must have been involved in some ways with the Core Curriculum, but we're talking about this specific idea's implementation.

TFA refers to "back-mapping" in a way that suggests the new curriculum was designed by reading a college syllabus and then winging it from there. It's pretty obviously a bit deeper than that, even just from reading the .ppt they link to. Furthermore, I read TFA's reference to "no evidence" of ECE expert involvement as meaning no evidence cited in the .ppt, which is wrong in any case, but it's clear that there was ECE expert involvement in the development of the curriculum.

Incidentally, the phrase "number sentence" does not actually appear in the NYSED common core. "Create a story context" does. I imagine that will set off mefites' woo detectors even worse...

Yes, these pedagogical systems are extensively tested. But I want people to consider what is the issue here: human experimentation. There are rigorous protocols for human experimentation, but then, every teacher is pretty much doing a continuous set of experiments on human subjects with inadequately rigorous methods. That's part of what this Common Core system is about, to develop teacher's skills so they can deliver a rigorous system of instruction that is scientifically proven.

Pedagogical methods can be difficult to test, and results difficult to interpret, since the issues are largely sociological and psychological. About the only thing that can be tested with arbitrary precision is achievement. That's what I do for a living. You can set standards and see how well students achieve them. Testing can be done in clever ways that obliquely verify teaching methods, and this is all part of the evil horrible testing system that teachers hate so much because it is being used to assess if they are teaching effectively.

1) It doesn't say "what you know". It says "the part you know", the "missing part", and the "whole".

2) The pictures are there to help the student visualize the problem. They use cubes to represent jars because they are using snap cubes to visualize numbers.

3) It says "cubes", not boxes. It refers to snap cubes. It's like saying "use an abacus".

We agree that these skills are important and need to be taught to children, so that they can use these skills well as adults.

The thing is, backmapping entails proper planning. It's not good enough to merely

What matters is effective implementation. How well are you actually teaching and testing this material? Whether this is a worksheet or a test, it's indicative of poor implementation: not just in this worksheet, but as a general culture and process. Some ECEs may have been involved at some points in this general process, but either they were not consulted appropriately at the right points in time, or the ECEs weren't being adequately listened to, or some people need to be replaced, etc. etc. etc.

Perhaps we can agree on this: this worksheet does not indicate a professional understanding of how to teach this material to first-graders. I assume that we could also find some middle ground on the idea that the worksheet does not exist in a vacuum - if this was constructed poorly, then other things probably are, as well.

I guess I don't agree on that, but I'm not an early childhood educator so I'm sure there are issues I'm not aware of. What aspects of it did you feel weren't up to professional standards? I see one - as many have mentioned, there's a typo in question 12 that somehow made it through without being corrected.

All I can say is that I didn't find it confusing (which doesn't really matter, I'm a grownup) and my kid, whose school uses a curriculum a lot like this one, didn't find it confusing.

That would be so much more reassuring if the word EFFECTIVELY was stuck between 'can' and 'deliver'. Because from what I've seen firsthand, and the complaints I've gotten directly from teachers about students in their classes, they're not delivering whatever product they're delivering EFFECTIVELY.

And if you're trying to develop teaching skills, why are you testing students and not teachers?

> *I also notice that the old "Dick and Jane" names have now been universally disdained in favor of random world ethnic names*

"Dick" and "Jane" are no less ethnic than "Faiza," "Roberto," "Carrie," and "Jennifer," which are the names used in this work sheet.

First, their source for poorly-planned "back-mapping" is to cite a document that in fact claims extensive planning of the exact type that you describe. From the .ppt:

–The Common Core Standards are benchmarked to international standards and informed by the best evidence and research.

I can't vouch for the truth of these claims, and it sounds like your wife's actual experience doesn't either, but the point is they are from the document that the article cites as evidence for the opposite conclusion.

Second, the article and the FPP deliberately lead people who are confused by the new material to conclude indignantly that the material itself is flawed. In fact, a lot of the objections I've read so far reflect mathematical misunderstandings of the exact type that these curriculum reforms are designed–effectively or not–to correct.

If anyone wants, I can upload photos of my first-grade student's current math homework worksheets so y'all can see how this is being implemented in 2013.

The Common Core is a set of standards. It is not a textbook or a collection of assignments. All of those things get created by shitty, corner-cutting publishers. You can look at early-grades math worksheets from any mass curriculum and see similar layouts and degree of attention to detail.

Teachers are tested. But you don't tend to hear about it because they are grown adults and their parents aren't hovering over them.

I agree that the article is not great, and that it doesn't prove everything that it sets out to prove.

I confess to not having read most of the comments before posting. Now that I've read more of the comments, I agree that many people didn't quite get the point that this worksheet was using the language that the material had almost certainly been taught in.

My main point is that it's not enough to have a set of guidelines which make sense with regard to a set of goal-oriented, broad-gauge issues. If these guidelines, when followed in the real world, can result in substandard results, then there is a problem.

Where my wife comes into it: she teaches in a school with a high proportion of ESL students. She teaches both general and special needs students. To make a long and complicated story short, in her experience, these guidelines (and others like it) have had a particularly negative impact on many of her students. In her experience, the new guidelines can work for the higher-performing students, but they leave the lower-performing students further behind. The underlying conceptual framework does not speak to the capacity and needs of all students. The theoretical ambitions of these guidelines do not help a student whose math skills are far lower than they would have been, if they had been taught effectively in another way. For special needs students, she finds that their results improve dramatically when she can teach them in a different way.

But, you can't do that for everyone. What's more, you can't just say "but this conceptual way of doing things will help you in college" to a kid who can't do grade-appropriate math

Of course this testimony is only secondhand and anecdotal. But, I certainly hear about it often enough!

To me, those statements are overly vague and conclusory, especially with regard to the worksheet that was up for discussion. I agree that ECEs were undoubtedly consulted for the general plans, but the specific implementation under discussion does not show a clear understanding of how to teach and test a first-grader.

For me, the big question is: what happens when these new guidelines work in many schools, but in other schools, spur wider achievement gaps? It's not enough to say that these guidelines will help do xyz in the future. How are they working

Actually, I have heard this criticism before. "New math" means that kids with bad verbal skills (because of learning disabilities or ESL) are now ALSO flunking math. I think what bothers me most about these tests are that they introduce a million cultural variables and quirks that demand teaching to the test, and advantage the kids with a certain cultural competency. And it's just distracting -- why even risk having kids go huh? at the name "Faiza" and wonder why she has all those purses, and why you are taking some of them away, when you could just ask them 7 - 5 = ?

There's plenty of criticism the Pearson work sheets deserve. The names is not one of them. No kid is going to be confused to the point of not being able to answer the question because one of the people is named Faiza.

Here's the thing. Parents help kids with homework, that's good. But when parents who've learned a one method try to explain it to kids who've learned a different one, tears and frustration ensue.

So if any elementary math teachers are reading this,*please for the love of god*, stand at the blackboard and make a video demonstrating your method. It doesn't have to be slick, just work through a couple problems. *Then post that video on YouTube* so parents can see and understand where all those extra zeros are coming from.

Thank you.

That presumes the parents speak English, have a way to watch YouTube, will understand the explanation, and give a crap. I understand the frustration -- there have been times lately when I haven't understood my son's 5th grade math just because it's being taught differently from how I learned it decades ago -- but YouTube videos are not the solution.

Like lots of people, I'm not crazy about the New New Math. However, part of my reticence to accept criticisms of Common Core standards at face value are cack-handed attempts to discredit them like this.

OK, wait, what? Really? Three kids in my brother's (midwest suburban) graduating class were named "Faiza" (I just checked the graduation program to be sure). Nobody in first grade in the United States today is going to fail math because of a stereotypically non-white name on a worksheet.

So many thoughts about this -- sooo sooo many. Let me start with one simple sentence and then pull it apart to tell you how many issues are wrapped up in Common Core standards.

These are very high stakes tests.

1. Decisions about teachers jobs, ratings, program evaluation are being made based on the outcomes of this new test.

2. Decisions about children's ability to advance to the next grade will be made based*almost only *on the outcomes of this new test.

3. Teachers will inevitably teach to the test -- and Pearson will happily sell you, thank you very much, a hastily put-together curriculum that*should* be pegged to the test -- but that's not a slam dunk anyway, even if you wanted to teach to the test.

4. There are a lot of faulty assumptions wrapped up in this "standardization" - that same aged kids progress at the same rates, for example.

5. Just because being able to explain abstract mathematical concepts is potentially useful as an adult, it doesn't mean that kids, at the age of five or six, need to get started on this RIGHT AWAY! That's not how human beings progress. I don't let my 8 month old wander over to a hot stove and touch it just because she'll need to know someday, on her own, not to touch a hot stove.

6. If one wanted to encourage a national curriculum, one could, in theory, start testing it before making it the basis by which teachers are judged and kids are granted passage to the next grade. And then you could start with a kindegarten class, institute it in that grade only, and try it out -- all while allowing teachers to also assess the child's skills and readiness for the next grade based on something other than the untested test, as it were.

That's all I have time to write now -- but I gotta go to work.
