What is the New Math Curriculum? New Mathematics or New Math was a brief, dramatic change in the way mathematics was taught in American grade schools, and to a lesser extent in European countries, during the 1960s. The name is commonly given to a set of teaching practices introduced in the U.S. <p><a href="http://feedads.g.doubleclick.net/~a/NeW2jbw-jDenZthIjcJtxDpmFn4/0/da"><img src="http://feedads.g.doubleclick.net/~a/NeW2jbw-jDenZthIjcJtxDpmFn4/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/NeW2jbw-jDenZthIjcJtxDpmFn4/1/da"><img src="http://feedads.g.doubleclick.net/~a/NeW2jbw-jDenZthIjcJtxDpmFn4/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/MathematicsVideos/~4/Cce37SkDwL8" height="1" width="1"/>http://mathvideos1.blogspot.com/2010/08/new-mathematics.htmltag:blogger.com,1999:blog-2432904218206318670.post-85522019446741992432010-08-07T05:33:00.001-07:002010-08-07T05:47:37.933-07:002010-08-07T05:47:37.933-07:00yrlynznoreply@blogger.com0It's not actually the history of mathematics but the history of numbers. Nevertheless, I find this video a very good synthesis of the history of numbers. It's very informative and Grades 5 and 6 students can easily relate to it. <p><a href="http://feedads.g.doubleclick.net/~a/dyAL6E_j-npQyCX9FwQC_Y9tTu0/0/da"><img src="http://feedads.g.doubleclick.net/~a/dyAL6E_j-npQyCX9FwQC_Y9tTu0/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/dyAL6E_j-npQyCX9FwQC_Y9tTu0/1/da"><img src="http://feedads.g.doubleclick.net/~a/dyAL6E_j-npQyCX9FwQC_Y9tTu0/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/MathematicsVideos/~4/uGwlSfJGPX0" height="1" width="1"/>http://mathvideos1.blogspot.com/2010/08/history-of-numbers.htmltag:blogger.com,1999:blog-2432904218206318670.post-82490974826744432642010-08-05T19:04:00.000-07:002010-08-10T14:05:33.440-07:002010-08-10T14:05:33.440-07:00yrlynznoreply@blogger.com0This man thinks that students dismal performance in mathematics has to do solely with the math curriculum.  I say, nothing beats a good math teacher who knows his mathematics and how to represent and present its ideas to students. <p><a href="http://feedads.g.doubleclick.net/~a/-fGl7SbJ2HsIl99J5ncXIXzQBLA/0/da"><img src="http://feedads.g.doubleclick.net/~a/-fGl7SbJ2HsIl99J5ncXIXzQBLA/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/-fGl7SbJ2HsIl99J5ncXIXzQBLA/1/da"><img src="http://feedads.g.doubleclick.net/~a/-fGl7SbJ2HsIl99J5ncXIXzQBLA/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/MathematicsVideos/~4/6flJFM4WVac" height="1" width="1"/>http://mathvideos1.blogspot.com/2010/08/its-math-curriculum.html
