CE1 \u2014> Conna\u00eetre et utiliser des proc\u00e9dures de calcul mental pour calculer des sommes, des diff\u00e9rences et des produits.<\/p>\n\n\n\n

CE2 \u2014> Calcul sur des nombres entiers \/Calculer mentalement

SOCLE COMMUN :
CE1 \u2014> L\u2019\u00e9l\u00e8ve est capable de :

R\u00e9sum\u00e9<\/strong>
Activit\u00e9 ritualis\u00e9e que l\u2019on peut proposer lors des 15 minutes quotidiennes de calcul mental.<\/p>\n\n\n\n

But du jeu : utiliser les nombres \u00e0 votre disposition pour trouver le r\u00e9sultat indiqu\u00e9 pr\u00e8s des \u00e9toiles. Vous pouvez additionner, soustraire, multiplier ou diviser.<\/p>\n\n\n\n

Diff\u00e9renciation p\u00e9dagogique : pour chaque s\u00e9rie de nombres 4 r\u00e9sultats sont propos\u00e9s.
Les \u00e9toiles rouges sont pour les CE1 – 1 \u00e9toile : r\u00e9sultat facilement accessible \/ 2 \u00e9toiles : r\u00e9sultat qui n\u00e9cessite des strat\u00e9gies plus complexes
Les \u00e9toiles bleues sont pour les CE2 – 1 \u00e9toile : r\u00e9sultat facilement accessible \/ 2 \u00e9toiles : r\u00e9sultat qui n\u00e9cessite des strat\u00e9gies plus complexes<\/p>\n\n\n\n

L\u2019int\u00e9r\u00eat du paperboard\u00a0: l\u2019enseignant peut noter les diff\u00e9rentes strat\u00e9gies des \u00e9l\u00e8ves + il peut les sauvegarder et donc revenir dessus lors de s\u00e9ances ult\u00e9rieures.
Mots cl\u00e9s pour la recherche<\/strong>\u00a0: calcul mental \/ diff\u00e9renciation \/ quatre op\u00e9rations<\/p>\n\n\n\n
