Abscisses de points et règles graduées. Tous les abscisses tombent sur des dixièmes sauf un pour introduire les centièmes. `Abscisses de points et règles graduées <./abscisse_fractions.pdf>`_ . Les élèves doivent retrouver la longueur des segments en utilisant la règle la plus appropriée. Il sera intéressant de faire le point sur les graduations de chaque règle.
/!\ à faire On peut découper la partie avec les règles pour faciliter les manipulations.
Tous les abscisses tombent sur des dixièmes sauf un pour introduire les centièmes.
Bilan: On donne l'abscisse de certain points avec les dixièmes et on introduit les nombres décimaux. Bilan: On donne l'abscisse de certain points avec les dixièmes et on introduit les nombres décimaux.
