Polydrons
You can purchase Polydrons from the following source:

An alternative to purchasing Polydrons is to make cutouts of regular polygons from stiff paper or poster board and use tape to attach them. Each individual working alone or pair of participants will need at least 32 triangles, 12 pentagons, six squares, and three hexagons, but it's helpful if each pair has extra sets of each kind of polygon.
