Students must be able to identify three-dimensional solids, including cylinders, cones, spheres, and cubes. Students should be able to identify three-dimensional solids by the number of faces, bases, vertices, edges, curved surfaces, etc. the solids may have. Students may also find the solids' abilities to roll, stack, or slide helpful in identifying the solids. Students should realize that the identity of the shape is not changed by its orientation, size, color, or texture.
