Using simple materials, students build three-dimensional models of five geosolids, or regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron

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.
