Put together cool looking models of geometric shapes you’ve never seen outside of D&D dice. Paper Models of Polyhedra is a collection of great 3D projects collected on a site whose name I can’t pronounce (korthalsaltes.com)–fitting, given the names of polyhedra like rhombicuboctahedron and icosicosidodecahedron.
“Polyhedra” sounds like the name of the scary, multi-headed serpent Odysseus fought in The Odyssey. For geometry students, wrapping their heads around a great icosahedron without a visual aid is probably just as frightening. These are great projects to help them visualize the shapes. Add some paint and markers and they can also make great art projects. A few of the pointier ones could conceivably be used as weapons – handy if you ever run across a six-headed
