Nombre Cible

Nombre Cible est un exerciseur permettant de jouer au jeu du "Compte est bon". Cycles concernés : Cycles 3 et 4 Compétence visée : Nombres et calculs : Pratiquer le calcul mental et réfléchi. CONTENU : Plusieurs paramètres sont disponibles : - Niveau de difficulté (mini-cible ou maxi-cible) ; - Délai de réponse (1, 2, 3, 5 minutes ou délai illimité) ; - Mode de calcul : automatique ou non. Mode automatique Dans ce mode, les calculs sont effectués automatiquement par l’application, dès lors que le joueur a choisi deux nombres et une opération. Mode manuel Dans ce mode, dès lors que le joueur a choisi deux nombres et une opération, un clavier apparaît... le joueur doit alors indiquer le résultat de son calcul avant de pouvoir passer à la suite. Le résultat est contrôlé, et, en cas d’erreur, une alerte est affichée. Vérification des calculs Dans les deux modes, une alerte est affichée si : - une soustraction donne un nombre négatif (nombres négatifs interdits) ; - une division donne un nombre non entier (seuls les entiers sont autorisés). En mode manuel, une alerte est affichée si le résultat du calcul n’est pas correct. Fin de partie La partie s’arrête automatiquement si le nombre cible est trouvé. A tout moment, il est possible de proposer le dernier nombre trouvé comme réponse. Parfois, il n’est pas possible de trouver exactement la cible... Dans ce cas, si l’élève trouve la valeur la plus proche, il gagne la partie (avec une précision de 100%).
