Some of my earlier well-known origami like WXYZ and Blintz Icosidodecahedron belong to the genre of planar modular origami. These were inspired by work by earlier folders like Robert Neale‘s Skeletal Octahedron (mid 1960s), ED Sullivan‘s XYZ (1976) and Philip Shen‘s Omega Star (1976). Meenakshi Mukerji (2003) observed that one family of planar modular origami […]
This session for the Mathematical Association Annual Conference 2021 presents some ideas for using origami for teaching and learning mathematics. It covers some mathematics arising from a single fold, fractions, how to trisect a right angle by folding paper and therefore make an equilateral triangle, a six-pointed star, a tetrahedron and an approximation of a […]
This session for Association of Teachers of Mathematics 2021 Annual Conference will give you some ideas for using origami for teaching and learning mathematics. It covers fractions, volume, curves from straight folds and more.
