We have a couple of old fold up platonic solids that we printed from Laura Taalman’s Makerhome blog. For example:
These models proved to be extremely helpful when we were talking through the section in our geometry book on regular polyhedra today. They even help you see the dual properties of cubes / octahedrons and icosahedrons / dodecahedrons.
Happy to have these props – another great example of how helpful Taalman’s blog has been for us!
