The video explains the new ways children are taught division and multiplication and what is wrong with new new math (not to be confused with the <a href="http://en.wikipedia.org/wiki/New_Math">new math</a> that was taught in the sixties) or <a href="http://www.time.com/time/magazine/article/0,9171,986895-1,00.html">whole math</a>. From the textbook in the video:<i>The authors of Everyday Mathematics do not believe it is worth students’ time and effort to fully develop highly efficient paper-and-pencil algorithms for all possible whole-number, fraction, and decimal division problems. Mastery of the intricacies of such algorithms is a huge endeavor, one that experience tells us is doomed to failure for many students. It is simply counter-productive to invest many hours of precious class time on such algorithms. The mathematical payoff is not worth the cost, particularly because quotients can be found quickly and accurately with a calculator.</i> tag:metafilter.com,2008:site.74653 Sat, 06 Sep 2008 03:02:27 -0800 education learning math mathematics newmath newnewmath school wholemath davar
