Des exercices avec les maisons des nombres
(Ajout le 06/10/2016 d'une fiche d'entrainement pour les maisons des 6-7-8-9.)
Suite à l'article présentant différents outils pour amener la notion de décompositions additives d'un nombre (voir ici) et des affichages, cette fois-ci je vous propose des "outils d'entrainement"...
Le premier "exercice" peut être proposé à la maison, en classe par binôme, lors des APC...
Un adulte/un camarade annonce une addition, l'enfant donne une réponse. Si cette dernière est correcte et rapide, on colorie en vert le point qui suit l’addition dans la maison des nombres.
Si la réponse est correcte mais hésitante, on colorie le point en orange.
Enfin, si la réponse est fausse, le point sera colorié en rouge.L'autre document est un travail individuel : il faudra coller les étiquettes (calculs) dans la bonne maison des nombres. La première fiche présente les maisons du 4-5-6 et la deuxième celles du 5-6-7.
