Étape 1
=======
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.
Étape 2

/!\ à faire
Dessin mystère avec des décimaux, des dixièmes, des centièmes...
`Dessin mystère <./dessin_mystere.pdf>`_ où il faut placer des points à partir de leur abscisse (avec des décimaux, des dixièmes, des centièmes...).
/!\ à faire
Bilan: passer des dixièmes et des centièmes à l'unité ou autres.
Bilan: La règle du dessin mystère sert de bilan pour passer des dixièmes et des centièmes à l'unité ou autres.
