Les multiplications

 

Les multiplications

 

Pour l'apprentissage des tables de multiplication, j'utilise, sur une période donnée, les cartes à Toto en calcul mental, très ludiques et pas chères du tout (cliquez sur l'image en bas de l'article pour aller sur un site marchand).

Je montre une carte aux élèves et ils écrivent le résultat sur leur ardoise (parfois je donne le résultat et ils doivent donner la(les) multiplication(s) qui correspond(ent).

Bref, je ne vous apprends rien....et afin d'avoir un regard sur ce qui est acquis ou non, les élèves valident une fiche d'évaluation continue, qui permet de voir rapidement quelle table est sue, et quelle table il faut revoir (aussi bien pour eux, que pour moi, que pour les parents !) .. et pour l'apprentissage, ce qui est su, n'est plus à savoir (en théorie ;-)) donc plus on a de vert, moins les devoirs du soir durent longtemps CQFD ! Généralement, ils deviennent vite autonomes sur ce genre de support et peuvent s'autovalider en dehors du temps collectif de calcul mental, par exemple pendant les jeux de calculs toujours avec ces fameuses cartes !

Une fois par semaine, je leur fais passer un petit test noté, histoire de donner du sens à cet apprentissage fastidieux de ces satanées X ... et pour les obliger à être sérieux ...(tout de même, nous ne sommes pas là pour rigoler.. enfin, pas que.. !)

Et voici 7 x 8 un logiciel gratuit créé par un collègue pour apprendre ses tables de multiplication sur l'ordinateur.

Deux versions sont disponibles : une pour la maison et une pour la classe. C'est super, non ? Et bien c'est par Les multiplications  !

 Lorsque les tables commencent à être maîtrisées, on lance des défis chronométrés comme ceux des générateurs de Charivari pour travailler la rapidité ou encore avec ses ceintures de tables de multiplication (j'adore !).

et chez Orphys ce sont les multivitesses.
