This is great website from Joseph O’Rourke, author of “How to Fold It: The Mathematics of Linkages, Origami,and Polyhedra” .

The website has several videosand cool animations that demonstrate some of the basic ideas in mathematical folding, like the one-cut problem** , **the map puzzle, and folding polygons into convex polyhedra.

There are also a few folding patterns available for download, just in case you’d like to produce a turtle with one cut!

And for more resources on math and origami, check out my fun with folding page!
