Yesterday we did a fun project on angles in Platonic solids:
Talking about Angles in Platonic Solids
We ended up getting a really neat comment from Allen Knutson on that project. He said:
“You should look for the three orthogonal golden rectangles in an icosahedron! They’re easy to see in a Skwish toy.”
My older son was working on a different math project today, so I had my younger son build an icosahedron out of zome and look for those rectangles. Here’s what he had to say after building the shape:
During his description he found a second rectangle. So, off camera, he filled in that rectangle and then had a bit more to say:
So, thanks to Allen Knutson for the comment that inspired this project, and thanks (as always!) to Zometool for making it so easy to get kids talking about math!
