Abstract

This paper describes the idea to design an origami in order to explain the scale ratio 1: 2 and the activities with it to develop geometric skills when folding a square it is possible to introduce reasoning related to linear and surface relationships. Many origami models allow to "see", in its multiple transformations during the folding sequence, polygons; in this case the sequence, which leads to the modelling of a 2D Fractal model, allows us to introduce not only the recognition of plane figures but also the concept of passage of scale, to become familiar with the concept of fractal, to observe fractions and visualize equivalent areas.
