This is the most comprehensive collection of 'hands-on' paper math that I have ever seen under one cover. Paper folding is a simple, novel, hands-on approach to mathematics. Today too many students are beginning to identify mathematics with technology use.
Paper folding is useable from grade school through college.
Because the material is meant to be a resource for the teacher, the information could be readily used at all levels. In grade school the fraction and tessellation units would be great. In later grades the geometry would be introduced. At the college level the material would be useful for developmental mathematics and as a component to teacher education classes.
