DIAGONAL OF A SQUARE – LESSON PLAN
http://www.math.nmsu.edu/breakingaway/Lessons/diagonalofsquare1/diagonalofsquare.html
"One of the very important aspects of the mathematical method in science is its ability to isolate a few essential features and analyze them independently of any context. Most equations in physics have this property. But in schools, especially in the early grades, such an isolation of features often gives the impression that mathematics is simply disconnected from the rest of the world. We present here an introduction to some important algebraic concepts that can be introduced in the early grades in a concrete setting." Excellent
