Investigate the concepts of area, volume, 3D shapes, and nets using this interactive Learn Alberta math. The solid shapes focused on this exploration include rectangular and triangular prisms, rectangular and triangular pyramids,...

Generate different "nets" for paper construction of common three-dimensional shapes: cube, cuboid, pyramid, cone, tetrahedron, cylinder, octahedron, rhombic prism, dodecahedron, pentagonal prism, and pentagonal prism.

Cool visual site that shows a 3-D image of the various hybrid orbitals that are possible. Requires the CHIME plug-in to view images.

Check out this math project about polyhedra! Students will enjoy the hands-on activity while they learn about tetrahedrons, hexahedrons, octahedrons, dodecahedrons, and icosahedrons. [Requires Adobe Reader.]

Monterey Peninsula College faculty page simply shows a 3-D image of a Pi bonding orbital. Requires the CHIME plug-in
