Geometria tra realtà e teoria

This volume collects part of the work carried out during the first year of the II level Master “Trainer Profession in Didactics of Mathematics”, organized by the University of Turin, Faculty of Mathematics. In particular it collects the works of reflection and the didactic proposals that the various groups have developed during the Geometry course held by Professor Ornella Robutti. Three M@t.abel activities are analyzed (the mast, the clock and Let’s explore the flat figures) proposing for each of the adaptations to different school orders, some reflections on the evaluation and in particular the INVALSI. The content of this book is centered on a laboratory approach to geometry and is intended for all teachers who wish to experiment with our proposals.
