Being able to hold the shape in your hands really helps with keeping track of the vertices and edges especially when it is a shape bigger than an octahedron. I know that I had a hard time working at station 1 with ipads because it had two shapes bigger than an octahedron and it was really hard to try and figure out how many vertices and edges they had since it wasn't tangible. Below are the classifications for each three-dimensional shape.
A cube is composed of six square faces, eight vertices, and twelve edges.
A Pyramid has one square face as the base and four triangle faces, five vertices, and five edges.
A Tetrahedron consists of four triangle faces, four vertices, and six edges.
An octahedron is made up of eight triangular faces, twelve edges, and six vertices.
