# Use representations to round a decimal number with tenths to the nearest whole number

I can use representations to round a decimal number with tenths to the nearest whole number.

## 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 to the next whole number.
- If the value of the tenths is less than 5, round to the previous whole number.

### Common misconception

Pupils say the previous multiple of one as a whole before e.g. previous multiple of 3.4 as 2 or 2.4

Place the number on a number line and clarify the whole numbers it sits between.

### 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.

Next - Something that comes after something else.

Previous - Something that comes before something else.

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