Message to Teachers
Dodecahedron Day is about exposing students to the magical world of polyhedra. I can still remember building my first model, a white icosahedron with orange triangles connecting the midpoints of the faces, in Mrs. Kilbert's algebra class.
It's immensely satisfying to build a model you can hold and look at over and over again. Students should create for themselves. Please do not set up contests centered around Dodecahedron Day. Rather, encourage creating models for the fun of it.
- Polyhedron Models by
Magnus J. Wenninger. The classic book for building models of polyhedra. Many nets for these models appear on the "Nets" page. Cambridge University Press, 1971. ISBN: 0-521-09859-9.
- Spherical Models by
Magnus J. Wenninger. The classic book for building spherical (geodesic) models of polyhedra. Many nets for these models appear on the "Nets" page. Dover reprint.
- Regular Polytopes by H. S. M. Coxeter. Another classic, but mathematically intense. Covers coordinates, symmetries, and higher dimensions. Dover reprint, 1973. ISBN: 0-486-61480-8.
- The Geometrical Foundation of Natural Structure by Robert Williams. Wonderful sourcebook for structures based on polyhedra. (The net for the rhombic dodecahedron is from this book.) Dover reprint, 1979. ISBN: 0-486-23729-X.
- Polyhedra and Geodesic Structures by Vincent J. Matsko.
An intermediate text discussing the design of geodesic structures using only basic trigonometry. The textbook is used for a
Polyhedra and Geometric Sculpture course (formerly Polyhedra and Geodesic Structures) at the Illinois Mathematics and Science Academy. The text is available for download on the course website.
