ABSTRACT
Summary The idea here is to have a sequence of handouts that let students explore the concept of Gaussian curvature, see that paper (and thus all folded models) have zero curvature, and explore what implications this has on rigid origami. Diagrams of the Miura map fold are given to illustrate a model whose vertices pass the rigidity test. Some simple vertex folds and the hyperbolic paraboloid are given as examples that don’t work.
