Platonic Solids

A platonic shape is a 3D object made up of identical geometric/polygonal 2D shapes on all sides.

Tell me more: Studying geometry or architecture in two dimensions is important, but doing the same thing in three dimensions is essential. Working in multiple planes gives us an understanding of how to bend and create space, and it allows us to engage with ideas like symmetry, volume and angles in a spatial way. Using scissors, tape and templates, we invite students to carefully cut out, crease, fold and glue their own models until the class develops a large landscape of platonic solids.

Go further: The five “regular” solids can be seen in chemistry, crystals and rocks! (Those are the tetrahedron, octahedron, icosahedron, dodecadedron, and cube.) How might these objects be used together to create models? Or be hung in a mobile? Constructed of material other than paper? Used in a board game?
