Using simple materials, students build three-dimensional models of five geosolids, or regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron. The included activities have students note the number of vertices, edges, and faces of each structure, which is used to help them build the structure.
Includes 100 straws, 100 pipe cleaners, teacher instructions, and a student user guide.
