Icosahedron

Develop cognitive and geometric abilities through paper model building

An icosahedron is a Platonic solid comprised of twenty triangular faces, 12 vertices and 30 edges. In this model the icosahedron is regular, meaning that all of the triangles are identical equilateral triangles. It is a moderately difficult model to construct.

Tab and fold lines are available on the model but can be hidden if you do not want them. The outline is always present, but can be minimized to a very thin, light line so that it does not show up on the physical model. A small preview of the model also appears on the sheet, but you may want to hide this if you think it gives away too much to the student.
