Découverte des tableaux de fonctions et des tableaux de signe
|
||||
-------------------------------------------------------------
|
||||
|
||||
Cette activité a pour but de faire comprendre aux élèves que l'on peut décrire les fonctions sans donner des valeurs. Elle les obligera à les faire communiquer entre eux et à se rendre compte des éléments importants à se transmettre.
|
||||
|
||||
Description
|
||||
-----------
|
||||
|
||||
Les élèves sont en binômes. Chaque élève a un tas de cartes où sont tracé des fonctions. À tour de rôle, ils devront décrire la fonction à leur camarade qui devra essayer de la tracer le plus fidèlement.
