Géométrie et manipulation au cycle 2 : manipuler les formes constituant des figures complexes pour mieux identifier les propriétés géométriques en jeu

Abstract : Among researchers, there is a current agreement on the usefulness of handling: student interest, multi-sensory approach, help tool, cognitive discharge, input for the teacher, etc. It is also put at the center of school news by Institutional Expectations. Admitting this working hypothesis, the problem arises between the readings and a statement drawn up in a key stage 2 class. It is a question of studying the contributions of handling in geometry, in CE1, during a situation of communication in which the transmitting pupils must describe an assembly consisting of two simple shapes, in order to allow the pupil receivers to reconstruct it, using handled shapes. The results of this study made it possible, for most of the participating students, to validate the assumptions made. Thus, handling makes it possible to better recognize and use the spatio-geometric properties of plane shapes in the proposed assemblies, and it constitutes a way of mathematical validation. Aside from students in difficulty, manipulation is therefore a relevant pedagogical modality to ensure the transition between perceptual geometry and analytic geometry.
