Pythagorean Theorem
(Mod IV)

Enter
M4

The next page shows you how to make Pythagorean theorem easy and understandable for little kids.

Start by building squares. Talk about square roots, & what the symbol means.  Then build Triangles using your squares. The 3-4-5 Pythagorean triple, is small and easy to count for little kids. But the concept is huge.


a2 + b2 = c2

The next page contains video & lessons to help you make this concept easy for your kids. This is one of the basic building blocks for Trigonometry. Understanding this concept early on lowers the cognitive load later.

This page will help you avoid the problems that this student and teacher had.



Mathematics really can be child's play. Just because this is part of module four doesn't mean you can't start fooling around with the lessons you find on the next page at the same time they're learning other basics like addition or division. Square numbers should be part of your early lessons (use module three password), on the next page you'll see little second graders having fun with this concept.

There are two videos
 that show classroom full of second graders who were only seven and eight years old building pyramids out of squares like the one you see above and counting them as part of the lesson. None of them thought it was hard, or difficult to understand. In fact they went home and explained it to their parents who later mobbed me at a birthday party when they discovered I was the guy that had taught their children Pythagorean theorem. 

The children came home excited and happy...And when the parents asked, "what did you learn today?" Their children could explain this fundamental theorem, much the amazement of one of the parents who had a degree in physics, & who would never have thought of teaching his little daughter this until high school.

Here are some triples to get started with. You can also double or triple them. In other words (3, 4, 5) & (6, 8, 10) & (9, 12, 15) all work and are easy to build with blocks.
