RAPPEL :

Nombre de ... et chiffre de ...

Quand on cherche le "nombre de" centaines, on compte aussi les milliers. Le nombre de centaines est 23

Quand on cherche le "nombre de" dizaines, on compte aussi les milliers et les centaines. Le nombre de dizaines est 234

Pour le "chiffre de" ... on ne prend que la colonne qui nous intéresse. Ici les centaines. Le chiffre des centaines est 3

Ici les unités. Le chiffre des unités est 1

Quel est le nombre de centaines ?

Dans le nombre : 9 634

96

Quel est le chiffre des unités ?

Quel est le chiffre des centaines ?

Quel est le nombre de milliers ?

Dans le nombre : 8 051

Maintenant nous allons apprendre à décomposer !

5 023

5 000 + 20 + 3

(5 x 1 000) + (2 x 10) + 3

2 341 c'est : 2 milliers + 3 centaines + 4 dizaines + 1 unité

2 341 = 2 000 + 300 + 40 + 1

456 =

400 + 50 + 6

2 000 + 600 + 20

2 620 =

5 000 + 20 + 7

5 027 =

De la même façon, décompose

2 341 c'est aussi: 2 x + 3 x + 4 x + 1 x

2 341 = (2 x 1 000) + (3 x 100) + (4 x 10) + 1

456 =

(4 x 100) + (5 x 10) + 6

(2 x 1 000) + (6 x 100) + (2 x 10)

2 620 =

(5 x 1 000) + (2 x 10) + 7

5 027 =

De la même façon, décompose

Exercice 1 : Décompose comme dans l'exemple : 2 501 = (2 x 1 000) + (5 x 100 ) + 1 4 305 3 007 5 470 2 326

Exercice 2 : Décompose comme dans l'exemple : 2 501 = 2 000 + 500 + 1 8 201 4 730 1 965 2 107
