Here is a couple of great ways to use straws and pipe cleaners to teach geometry. I have students create snowflakes and then discuss symmetry. To teach how to find the diagonal of the rectangular prism, have students create a 3-4-5 prism and then cut paper triangles to fit inside the prism. They can then prove to themselves that d = sqrt(l^2 + h^2 + w^2)!!!!!!! Enjoy!!!!

I love your blog! I’ve been following it for a while now and decided to nominate it for the Liebster Award. Head over to my blog to see what that entails!

Thanks for the idea. I have been trying to find a way to help students with this concept.

This is great! Can't wait to use these in my classroom! I also use pipe cleaners to demonstrate the triangle inequality theorem. Thanks for sharing:)

Yes that's great! I also use it for the hinge theorem.
