# Applying the Pythagorean Theorem

In this free math video we actually use the Pythagorean Theorem to figure out the answers to some problems about slides at a playground. They seem to understand it! I’m sure it will become even more clear over time, but I love seeing how easy Cuisenaire Rods make all of these abstract concepts that many kids struggle with!

Children in middle and high school would benefit from this type of introduction to right triangles, too! I sure wish I would have been taught this way!

# Introduction to the Pythagorean Theorem – Part Two

Here’s part two of our intro to the Pythagorean Theorem where we move on to introducing the actual formula of a^{2} + b^{2} = c^{2} to find the sides of a right triangle. The fact that they proved it for themselves first will help them to remember it in the future. It won’t be just another formula void of meaning to be memorized for a test.

Using Cuisenaire Rods or other similar manipulatives is an excellent way to introduce complex math concepts to children. They can see and touch math instead of just hearing and writing abstract symbols.
