Abstract EN:

The work begins with a historical and comparative approach to theories on games and their function in education, and a reflection on the problematics of teaching arithmetic to primary school children. There then follows an elaboration of specifics games. A first game "vamos aprender matemática". Based on a traditional format and intended for the Portuguese market, led to the development of a second, computer game, "la spirale". These two games form the basis for an evaluation of the progress of children in arithmetic, and on the relationships between mathematical competence and the observed strategical ability of the children involved.
