In School Year 2005/2006, we extended, in Italy, a part of a research initiated by Ewa Swoboda in Poland. Our research used simple tools but early results indicate that certain geometric aspects may depend on factors such as competency, psychology and gender. In this paper we present a preliminary analysis of the protocols and some hints to teachers about possible uses of these tools.
