Perhaps the best way to experience the properties of various geometric forms is to hold them in your hands. Regular geometric solids made from wood are a great educational materials for the classroom and homeschool learning environment. These sets often contain some of the Platonic solids (cube, tetrahedron, dodecahedron), as well as common solid forms (sphere, cylinder, and triangular prisms) which are used in basic calculations of volume or surface area.

These solids are invaluable tools for observation, comparison, discussion, connecting experiences with abstract mathematics, but also make for fun block play.
