ABSTRACT

Summary Students are shown a very simple modular origami unit that is made from business cards and asked to explore the kinds of objects that can be made with it.

Content This unit can make any polyhedron with all triangle faces and no vertices of degree 6 or higher. Thus, at a basic level this activity is about exploring such polyhedra, starting with the regular cases of the tetrahedron, octahedron, and icosahedron and moving into other solids like the triangular dipyramid and snub disphenoid.

Handouts (1) Describes how to make the basic unit and challenges the students to make
