Difficulty level:   #### Worksheet Overview

In this activity, we will round a decimal number to 1 decimal place.

Method

To round a decimal to 1 decimal place, we check the digit in the 2nd decimal place (i.e. the hundredths column).

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

If the hundredths digit is 4 or less, round DOWN. Examples

19.786 is between the 1 decimal place numbers 19.7 and 19.8

The 8 hundredths tell us to round UP to 19.8

19.786 rounds up to 19.8 to 1 dp

19.049 is between the 1 decimal place numbers 19.0 and 19.1

The 4 hundredths tell us to round DOWN to 19.0

19.049 rounds down to 19.0 to 1 dp

Does that make sense? Let's get started!
