Résumé

Cet article a pour thème le développement du sens des chiffres pour la multiplication et il est basé sur une étude de cas qui a vu le jour pendant le projet « Développer les sens des chiffres: perspectives et exigences du programme scolaire » réalisé au Portugal avec des enfants de 5 à 12 ans. La méthodologie utilisée était de nature qualitative et interprétative sous la forme d'une étude de cas. L'analyse est centrée sur les stratégies développées par les enfants pendant leur deuxième année de scolarisation (âgés de 7 ou 8 ans) lorsqu'ils doivent résoudre des problèmes comportant des multiplications qui font parfois partie d'une série d'exercices en classe. Les résultats montrent que le contexte des exercices, effectués en prenant comme exemple des rectangles, facilitent la compréhension de la multiplication, des propriétés de cette dernière et des relations numériques multiplicatives.
