Description: 
This virtual manipulative allows you to display, rotate, and resize Platonic solids. It also allows you to select vertices, edges, and faces, and show that the number of vertices minus the number of edges plus the number of faces is equal to 2 (Euler's formula).

Comment:  Being able to rotate a solid is a huge improvement over staring at a static image in a textbook. This tool makes it easy to count the faces, vertices and edges of a platonic solid.
