# "Your argument has to be beautiful."

The use of the Greek alphabet is particularly cruel, full stop. I've seen more people (myself included) become utterly frustrated with math because of an debilitating lack of penmanship experience with Greek letters. Nothing elicits more rage and contempt for every mathematician who ever lived than a malformed γ that morphs into an r after several pages of work.

In the class I'm teaching right now, we started talking about probability last week. Now, shh don't tell anyone what I've decided to do is not use any symbols at all, at least not for the first week. I told them to close the textbook and not open it for a week. (For a class that meets 100 minutes a day, 5 days a week for 5 weeks, that's a significant chunk of time.) We can do, and have done, an awful lot without having to resort to crazy formulas and runes all over the joint. We're getting away from that now, because we are starting to talk about continuous probability distributions (and it is much more difficult to avoid some of the symbology).

Surprise surprise, this class has actually done the best of any class I've ever had, in regards to the subject of probability.

The problem you encountered is likely due to the fact that mathematics "teachers" in third grade don't know

Wow, that article is awful. Can you imagine anyone saying, "We should teach students how to write sentences, but not paragraphs, since so few of them will end up as professional writers"? And when they describe math as a collection of formulas to be remembered, all I can think is, "Well,

Mmmhmmm. Along that same vein, interested folks may wish to consider these so-called "algebra tiles", which I have used in lower level classes with varying degrees of success. "Completing the square" ceases to be a meaningless catchphrase (as it may seem to the uninitiated) when you use these to factor polynomials.

The online tool is nice, but it helps if you have physical ones to play with also.

Paul Lockhart, author of the famous Mathematician's Lament, has a new book coming out called Measurement, which tries to discuss mathematics "as an artful way of thinking and living". Lockhart discusses his passion for math and motives for writing the book in this video.

The Mathematician's lament was posted previously by my brother a while ago and the discussion is still relevant, but this is a great post!

Yeah, that is a great essay (I'm not yet finished with). I've always done poorly with math, and always been interested in it, but when I would ask a teacher 'why' something was so, I'd get the answer: 'it just is' shutting down my interest. I started reading up on sacred geometry, gematria and astrology, which at least treat math as an art, and introduced me to some math principles and ideas in a context that made sense to me.

There are a lot of problems facing the United States in the next 20 years, but if I were pressed hard, I think the state of K-12 math education is chief among them on the list.

Why? Because we're facing this huge problem of global warming, and it's a problem that'll be solved to whatever extent by climatologists, physicists, chemists, biologists, engineers, economists, urban planners and architects - not to mention financiers and businesspeople. And every single one of those professions, at a very minimum, requires fairly advanced mathematical training.

Even the students who can get through this training often don't really

I was that kid. My pathological difficulty with math began as early as third grade, when we had to memorize hundreds of multiplication facts and I was among the last kids in the class able to do it. From then on math was a nightmare of teachers teaching algorithms and almost never ideas, insistence on perfect notation and symbols (the use of the Greek alphabet is particularly cruel when not paired with an explanation of what those symbols actually mean). It's like they all wanted kids to think of math as this weird rune-like language full of mystical power, instead of a shorthand way of expressing ideas that we encounter in life all the time.

For some reason, in my mid-20's, I got over my math phobia and I've since gone back to school, completed all those prerequisite classes and am applying to applied math and finance programs (still not sure which I want to do). But I wasted an awful lot of time being irrationally scared of the subject, and I think a lot of it has to do with the way math is taught by American teachers.

Meanwhile, people who don't have the patience (or have other, more immediately-gratifying interests) to grind out the years of boring rote-learning are quickly told that they are not "math people" and develop an almost pathological fear of any and all numbers.I was that kid.

*why*anything is what it is, and they couldn't do the mathematics without the formal symbol-pushing. To those people, that's all mathematics is.

I just want to know what kind of creative paradise that author went to school at. The "nightmares" he describes were exactly my experience in music and arts classes. Lots of rote, small doings and copywork and not a whole lot of actual creating. I get what he's saying about math classes though. The part about "a triangle is always half of the box its in" was news to me.

For me math got a lot more interesting when we did the logic unit. I wish we had done that sooner, and more of it.

Geometry -> Computational Geometry -> Algebra, that would have worked better for me than the other way a round. Then I would have welcomed the algebra, because it would have had some point, for solving the details of the geometries.

TRIGONOMETRY. Two weeks of content are stretched to semester length by masturbatory definitional runarounds.
