The other night, my husband and I were watching a rerun of Mythbusters (which is just a fantastic show, in my opinion) and one of the show's stars, Adam, was constructing a shape that would need to be inflated, so he decided to make an icosahedron.
I grinned immediately and wished that my students were watching the show with me.
Every single one of my students would have known that an icosahedron is a 20 sided figure. We had a very cool foam icosahedron with numbers on each face that we used this year in various math games.
Now, I wonder if Jamie and Adam from Mythbusters might be interested in some of our first grade math games?
