Key learning points
- Identify the next and previous whole numbers to the number being rounded.
- Identify which whole number is nearest to the number being rounded.
- If the value of the tenths is 5 or greater then round up to the next whole number.
- If the value of the tenths is less than 5, ignore the tenths and round down to the whole number.
- To round a number with hundredths to the nearest whole number, you only need to look at the tenths.
Common misconception
Pupils may mistake the previous multiple of one for example: previous multiple of 6.38 being 5.
Ensure pupils are given plenty of opportunities to place numbers on number lines, identifying the previous and next multiples of one.
