EFC1This is a step-by-step activity book that is taken in part from Folding Circle Tetrahedra. It is a good first step into the 9 creases of the tetrahedron in a workbook format following the progression of the tetrahedron as it is opened and joined in multiples to form the Five Platonic Solids as patten of organization and arrangement of spatial ordering. There is much to explore beyond the specific examples given in this book.

You can see more about this project on my blog or purchase the book online.
