The result of multiplying a number by  another whole number.

The point at which the numbers change into 100s numbers, or from one set of hundreds to another.

Find 10 more or 10 less than a given number

Maths

In this unit pupils will find pairs of number that compose 100. Pupils will position 3-digit numbers on a number line and estimate their position on unmarked number lines. They will compare and order 3 digit numbers. In the future unit pupil will add and subtract two 3-digit numbers using partitioning, adjusting, redistribution and bridging. 

In the prior unit pupils used known facts to find multiples of ten that composed 100  and used known facts to find complements to 100. In this unit pupils will find pairs of number that compose 100. They will position 3-digit numbers on a number line and estimate their position on unmarked number lines. They will compare and order 3 digit numbers.

Bridging 100: counting on and back in 10s, adding/subtracting multiples of 10

Use the number line representation to help you calculate 123 − 10
