Étape 1: Mesures avec une bande unité
=====================================
Une fiche avec des segments à mesurer en utilisant une bande unité.
`Une fiche avec des segments à mesurer en utilisant une bande unité <./E1_mesure_unite.pdf>`_
Avec la première bande unité, on a des nombres entiers et un segment où il faut plier l'unité en 2. Les élèves mesurent les segments et cherche une façon de d'être le plus précis possible.
La bande unité se construira avec des feuilles A4 prises dans la largeur et coupée en 2.
