:summary: Calcul mental pour les 3ePasserelles en 2017-2018
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 pleinière. 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 eventuellement les astuces que les élèves auront trouvées.
Le dernier "calcul mental" de la semaine est évalué (`fiche d'évaluation <./fiche_eval.pdf>`_). Ces évaluations mènent à une douzaine de notes sur 4 par trimestres qui sont ensuites converties en 3 ou 4 compétences **calculer**.
