Comment jouer ?
Découvre la masse de la boîte surprise
Clique et déplace des masses sur le plateau droit de la balance.
Observe bien : tu as des masses de 1kg, de 2kg et de 5kg.
Lorsque les deux plateaux sont à la même hauteur, ils sont à l'équilibre : les deux plateaux portent la même masse.
Lorsque tu as équilibré les 2 plateaux, clique sur le garçon. Si c'est juste, tu peux alors écrire la masse de la boîte dans le cadre rose.
Calcule la masse de la boîte : additionne les masses que tu as placées sur le plateau. Ecris ce nombre dans le cadre rose puis clique sur le garçon pour vérifier ta réponse.
Pédagogie
Manipuler des masses de 1kg, 2kg et 5kg pour équilibrer la balance avec un objet qui pèse entre 4 et 9kg.
Ce jeu fait intervenir l'observation du fonctionnement de la balance. Il permet également de travailler le calcul, en particulier les additions.
