Origametria and the van Hiele Theory of Teaching Geometry

The geometry curriculum implemented by the Israeli Ministry of Education follows closely the theories of the van Hieles [Fuys et al. 84, van Hiele 86, Burger and Shaughnessy 86]. In this paper, we show how the practices developed for the Origametria program can provide the solid foundation students need to prepare them to move into higher levels of abstraction in geometry.
