- Identify the next and previous multiples of 10 or 100 to the number on a number line.
- Rounding to the nearest 100, look at the tens value to decide whether to round to the previous or next multiple of 100
- Rounding to the nearest 10, look at the ones value to decide whether to round to the previous or next multiple of 10
- If the value of the digit you are looking at is 5 or more you round to the next multiple.
Keywords

Multiple - The result of multiplying a number by an integer. For example, multiples of 100 are 100, 200, 300, 400 etc.
Common misconception
A tricky digit for many pupils to consider is 0 because the rounded number is often the same as the original number. Pupils are often tempted to round to the multiple before the one they should.
Spend some time establishing with pupils that occasionally when zeroes are involved, the number does not actually change when it is rounded. Number lines are a great visual support when rounding, including in this aspect.
