In our Rounding Practice zone, you can practice rounding a range of numbers. You can round numbers to the nearest 10, 100 or even 1000. Want to round numbers to the nearest decimal place, you can do that too!
Select the numbers you want to practice with, and print out your results when you have finished.
You can also use the practice zone for benchmarking your performance, or using it with a group of children to gauge progress.
Here is our generator for generating your own rounding off numbers worksheets.
Our generator will create the following worksheets:
When you are rounding a number to the nearest 10, you are trying to find out which multiple of 10 your number is closest to.
The golden rule with rounding is that if a number is exactly halfway between two multiples of 10, you always round up.

Rounding Decimals
When you are rounding decimals, you will either be rounding to the nearest whole number, or you will be rounding to a given number of decimal places or significant figures.
Help with each of these options and examples is given below.
When you are rounding a number to the nearest whole number, you are trying to find out which whole number (or integer) your number is closest to.
How to round a number to the nearest integer (whole number)
Look at the tenths digit (the digit after the decimal point).
Examples
When you are rounding a number to the nearest tenth, you are trying to reduce your decimal to the closest decimal with just one decimal place.
How to round a number to the nearest tenth (or 1dp)
Look at the hundredths digit (the digit after the tenths digit).
Examples
Rounding numbers to 2dp (or 2 decimal places)
When you are rounding a number to 2 decimal places, you are trying to reduce your decimal to the closest decimal with 2 decimal places.
How to round a number to 2dp (2 decimal places)
Look at the 3rd decimal digit (the digit after the hundredths digit).
Examples
Here is our rounding decimal challenges collection which will give your child an opportunity to apply their decimal rounding learning.

Rounding numbers to Significant Figures
Rounding to significant figures is different from rounding to decimal places.
The first significant figure is the first non-zero digit a number has.
The second significant figure is the digit after the 1st significant figure.
The third significant figure is the digit after the 2nd significant figure, and so on.
See below for help to round a number to a set number of significant figures.
When you are rounding a number to 1 significant figures, you are trying to reduce the number to a single digit and zeros (and possibly a decimal point) to indicate its place value.
How to round a number to 1 significant figure
Look at the 2nd significant digit that the number has.
In a decimal, the first significant digit is the first non-zero digit. The 2nd significant digit is the digit after the first.
Examples
When you are rounding a number to 2 significant figures, you are trying to reduce the number to a two digits and zeros (and possibly a decimal point) to indicate its place value.
How to round a number to 2 significant figures
Look at the 3rd significant digit that the number has.
This is the digit which is two digits after the most significant digit.
Examples
When you are rounding a number to 3 significant figures, you are trying to reduce the number to a 3 digits and zeros (and possibly a decimal point) to indicate its place value.
How to round a number to 3 significant figures
Look at the 4th significant digit that the number has.
