Test Item Specifications
- The five Platonic solids (tetrahedron, hexahedron or cube, octahedron, dodecahedron, and icosahedron);
- Right or oblique prisms or pyramids with up to 12 edges on the base or composites;
- Composites of the right or oblique prisms or pyramids; and
- Other solids with fewer than 15 faces.
MA.912.G.7.2 Describe the relationships between the faces, edges, and vertices of polyhedra.
Students will identify the net for a given polyhedron and vice versa.
Students will identify and determine the types of faces and/or the numbers of edges, faces, and vertices of a given polyhedron or a given net.
Items will only include:
Items must not require use of formulas relating faces, edges, and vertices.
Items may not include cones, spheres, or cylinders.
Graphics should be used for most of these items, as appropriate.
Items may be set in either real-world or mathematical contexts.
Fill-in response items may require that students provide the number of edges, faces, or vertices of a given polyhedron.
