Abstract
This article presents some problems suitable for the introduction of the concept of equation and linear system. It contains the report of some of these experiments. In students from 12 to 14 years old the expèeriment was aimed to bring out any spontaneous pre-algebraical strategies. In students from 15 to 16 years old the goal was to introduce the concept of linear system and its procedures for solutions.| File | Dimensione | Formato | |
