Lesson Plans and activities for High School and some Middle School Math. Some activities look good for differentiation. Mainly for Algebra but other math subjects available.

Columbus State University’s College of Education is now the home of the Problem of the Week math contest, which was started in 1996 by David Rock and Doug Brumbaugh. The math educators also supply problems and answers that are part of the current White House Math Challenge, a presidential effort to boost interest in math and foster problem-solving skills. Visit our history page for more on these and the companion problem-solving sites here — Algebra in Action, Middle School Madness and Elementary Brain Teaser.

作科學研究常需要作些計算，可以幫我們作這些運算的軟體很多，其中最讓我印象深刻的是 Mathematica 及 Matlab 。它們用起來方便，功能更是不在話下，但就是要花錢買，而且還不便宜。
