In this worksheet, students round a decimal number to 2 decimal places. Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Round/Approximate Numbers Appropriately

Difficulty level:   #### Worksheet Overview

In this worksheet, we will round a decimal number to 2 decimal places.

Method

To round a decimal to 2 decimal places, we check the digit in the 3rd decimal place (i.e. the thousandths column).

If the thousandths digit is 5 or more, round UP.

If the thousandths digit is 4 or less, round DOWN.

Examples

19.746 is between the 2 decimal place numbers 19.74 and 19.75

The 6 thousandths tell us to round UP to 19.75

19.746 rounds up to 19.75 to 2 dp

19.342 is between the 2 decimal place numbers 19.34 and 19.35

The 2 thousandths tell us to round DOWN to 19.34

19.342 rounds down to 19.34 to 2 dp
