In the paper we present a didactic unit designed within a research project on Arithmetics. The unit objective is to introduce the notion of the Greatest Common Divisor through sona, sand drawings from African culture, and their representation by an appropriate software. A brief description of the project framework, the practice of the sona and the guidelines of the didactic proposal, as well as a sketch of the main characteristics of the SonaPolygonals_1.0 software are presented. The first findings of a pilot project at a few second grade lower seecondary schools in Italy will be also discussed in the DG15.

Abstract
In the paper we present a didactic unit designed within a research project on Arithmetics. The unit objective is to introduce the notion of the Greatest Common Divisor through sona, sand drawings from African culture, and their representation by an appropriate software. A brief description of the project framework, the practice of the sona and the guidelines of the didactic proposal, as well as a sketch of the main characteristics of the SonaPolygonals_1.0 software are presented. The first findings of a pilot project at a few second grade lower seecondary schools in Italy will be also discussed in the DG15.File in questo prodotto:
