I usually use have the students cut out and color graph paper squares to discover the Pythagorean Theorem. I recently read a great blog post about using centimeter cubes for this and couldn’t wait to try it. I cannot find that post now to give that person proper credit but I know it was in my Feedly or on WordPress. So please let me know if it’s you and I will link back!

The cubes were much easier than cutting, gluing, and coloring those graph paper squares! The kids had more fun too. Who doesn’t love to play with snap together cubes?
