## Lesson details

### 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.

### Keywords

Multiple - A multiple is the result of multiplying a number by an integer. For example 2 × 5 = 10 so 10 is a multiple of 2 and 5.

Previous - Something that comes before something else is known as the previous thing.

Next - Something that comes after something else is known as the next thing.

Rounding - Rounding means making a number simpler but keeping its value close to what it was.
