A large dodecahedron (12 sided polyhedron and member of the Platonic solids). These are shipped flat and require assembly. Perfect for teaching mathematics and geometry. Great for teaching shape recognition and the importance of polyhedrons and the platonic solids.
The dodecahedrons are roughly 4 inches (10 cm) wide. They are precut and scored from thick cardstock. They make an excellent mathematics related project out of coloring and constructing the platonic solids.
Each dodecahedron includes 0.25 inch (6 mm) long tabs to facilitate gluing the solid together. Typical school glues or all purpose glue works well. The shapes may be taped.
A Platonic solid is a regular, convex polyhedron. The faces must be polygons that are congruent (identical in shape and size) and regular (all angles equal and all sides equal). Also, the same number of faces must meet at each vertex. There are the only 5 solids that meet the specific requirements, which the dodecahedron is one of.
