I saw a neat tweet from Steve Phelps today:
We’ve done a couple of projects on the Rhoombic Dodecahedron before – here are three of them:
Using Matt Parker’s Platonic Solid video with kids
A 3D Geometry proof with few words courtesy of Fawn Nguyen
Penrose Tiles and some simple 3D Variations
After seeing Phelps’s tweet I thought it would be fun to see if the boys remembered how to find the volume of the shape. So, I built one out of our Zometool set and asked them what they knew about the shape.
Here’s what my older son had to say:

I’m glad I saw Phelps’s tweet – it was fun to revisit some of these old projects occasionally. Also, it was a nice reminder of how easy it is to share 3d shapes with kids using a Zometool set.
