:summary: Découverte des volumes du calcul du volume avec les 6e pour l'année 2017-2018.
Étape 1: Reconnaissance des volumes
===================================
`Objets du monde <./G1_reconnaitre_volumes.pdf>`_ à nommer.
Sur la cahier de bord, on colle la `fiche vocabulaire des volumes <./B1_volumes.pdf>`_.
Les élèves doivent ensuite reconnaître chaque volume dans les objets
On complète la fiche vocabulaire avec des exemples de chaque volumes.
Étape 2: Description des volumes
================================
En travail individuel, les élèves dénombrent le nombre de sommets, faces et arrêtes pour certains objets et écrivent leurs résultats dans `la fiche pour dénombrer <./E2_denombre_volumes.pdf>`_.
Puis en groupe, on cherche à décrire en une phrase comment on peut reconnaître le cube, le pavé droit et la pyramide (`decrire les volumes <./G2_decrire_volumes.pdf>`_)
Cahier de bord: Les phrases produites par les élèves.
Étape 2
=======
Mesure de tout ce qui est possible de mesurer sur des volumes physiques.
Cahier de bord: introduction du volume et de l'unité de volume.
Étape 3
=======
Empilement de cubes où l'on calcule les volumes
Cahier de bord: Formule du volume d'un pavé droit
Étape 4
=======
Tache complexe avec un calcul de volume.
