Virtual Polyhedra and the Real World
Overview Procedures for Teachers Organizers for Students


Using Web resources, students will study the complex geometric structures that are called polyhedra. Students will examine online models, create three-dimensional paper models, and view photographic, graphic, and animated examples of polyhedra. Students will create Web pages that illustrate their explorations and illustrate geometric solids beginning with the five platonic solids (tetrahedron, cube, octahedron, dodecahedron, and icosohedron), and extending to the more complex compound solids. Students will experience polyhedra geometry in an intuitive way and understand the complexity and beauty of these structures.

Learning Objectives

Students will be able to:

  • build and discuss models of polyhedra.

  • describe polyhedra solids in terms of vertices, edges, and faces.

  • identify all of the platonic polyhedra.

  • gain a thorough understanding of polyhedra through a hands-on approach to the subject.

  • work with models of polyhedra that can be shared, exhibited, and discussed to reinforce and expand ideas.
