\u00a0\u00a0Une des ruptures entre les entiers et les d\u00e9cimaux <\/u>est qu’il est toujours possible d’intercaler des nombres entre deux nombres d\u00e9cimaux (avec une infinit\u00e9 de solution).<\/b><\/h3>\n

Utiliser l’effet loupe est un moyen de comprendre\u00a0 l’intercalation toujours possible entre 2 nombres. Il est compl\u00e9mentaire avec le travail sur la droite gradu\u00e9e.<\/p>\n

\u00a0<\/strong>L’outil p\u00e9dagogique d’accompagnement propose une progression de l’utilisation de l’outil de la fin CM1 jusqu’en 6\u00e8me. Il propose aussi \u00e0 la fin des activit\u00e9s d’entra\u00eenement li\u00e9es aux savoirs g\u00e9n\u00e9r\u00e9s par l’outil.<\/b><\/span><\/p>\n
