It is important to understand place value before learning how to decompose numbers. For a reminder, read the concept sheet on Place Value.
A number can be decomposed using objects or pictures.
A number can be decomposed according to the positions of its digits.

76 |
7 Tens + 6 Ones = 76 |
|---|---|
|
231 |
2 Hundreds + 3 Tens + 1 One = 231 |
A number can be decomposed according to the value of each of its digits.
| 76 |
10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1 + 1 + 1 + 1 = 76 or 70 + 6 = 76 |
|---|---|
| 231 |
100 + 100 + 10 + 10 + 10 + 1 = 231 or 200 + 30 + 1 = 231 |

2 075 = 2 th + 7 t + 5 o
A number can be decomposed according to the value of each of its digits.
2 075 = 2 000 + 70 + 5
or
2 075 = (2 × 1 000) + (7 × 10) + (5 × 1)
It is important to understand place value before learning how to decompose decimal numbers.
For a reminder, read the concept sheet on Place Value.
A number can be decomposed according to the value of each of its digits.
104.32 = 100 + 1 + 1 + 1 + 1 + 0.1 + 0.1 + 0.1 + 0.01 + 0.01
or
104.32 = 100 + 4 + 0.3 + 0.02

659 038 = 6 hth + 5 tth + 9 th + 3 t + 8 o
or
659 038 = 659 th + 38 o
A number can be decomposed according to the value of each of its digits.
659 038 = 600 000 + 50 000 + 9 000 + 30 + 8
or
659 038 = (6 × 100 000) + (5 × 10 000) + (9 × 1 000) + (3 × 10) + (8 × 1)
or
659 038 = (6 × 105) + (5 × 104) + (9 × 103) + (3 × 101) + (8 × 100)
