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!
