Résumé: In this paper, we explore the use of manipulatives in the classroom to solve an arithmetical task via the concept of affordance. Manipulatives are part of the elementary class culture in different countries, and even if some studies question the efficacy of manipulatives, there seems to have a consensus around the necessity of using it. However, little is known about how mathematics is done with manipulatives. The analysis of pupils' actions helps put to light different affordances of two manipulatives: base-ten blocks and abacus, in a classroom setting where the operations of addition and subtraction are explored with pupils.
