*PRESENTATION : Type : Exerciseur méthodologique Cycles concernés : cycle 4, seconde Domaine du socle : 4 Compétence visée : Raisonner - Utiliser un raisonnement logique et des règles établies pour parvenir à une conclusion *DESCRIPTION : The Equations Game est un exerciseur méthodologique portant sur la résolution d’équations du premier degré à une inconnue, en cycle 4 et en seconde. Les calculs sont effectués automatiquement, l’exercice lui-même portant sur les actions à accomplir : ajouter, soustraire, multiplier ou diviser chaque membre de l’égalité par une même quantité (non nulle dans les deux derniers cas !). 15 niveaux, correspondant à des degrés de difficulté croissants, sont disponibles. Il n’est possible de passer au niveau suivant que si le niveau en cours est validé (obtention d’au moins une étoile)
