:summary: Quatre questions flashs à chaque début de cours pour les 5e en 2018-2019
|
||||
|
||||
Chaque début de cours commence par 4 questions. Les élèves ont tracé un tableau à 4 colonnes à la fin de leur cahier de recherche. Ils ne doivent écrire que la réponse aucune justification ne leur ai demandé.
|
||||
|
||||
La correction se fait en plénière. Ce moment doit être un moment d'échange. On cherche à donner la bonne réponse mais surtout d'expliquer comment l'atteindre. On essayera de faire ressortir la diversité des méthodes pour atteindre le résultats et éventuellement les astuces que les élèves auront trouvées.

||||

||||
Le dernier "calcul mental" de la semaine est évalué (`fiche d'évaluation <./fiche_eval.pdf>`_).
