These pieces permit assembly of 60 tetrahedral units, 78 octahedral units, 24 square pyramidal units, and 18 square planar units. Two or three kits are adequate for 20 students working in small teams, especially if larger structures are built by teams working together.

The blue pompom is normally used as the center atom for the tetrahedral units. The yellow pompom is normally used as the center atom for the octahedral units. Additional assorted colors are provided to represent more than one kind of atom.

See the directions or a movie to assemble the pieces into structural units that can be used for model building.
