Learn how to order decimals by size.
This lesson includes:
- one slideshow
- three interactive activities
Created in partnership with Twinkl
To order decimal numbers, you need to compare the place value of the digits in each number.
First you look at the digits in the largest place value position. If they are the same, look at the digits in the next place value position to the right, until you find a difference.
Which is smaller, 3.4 or 3.6?
The ones digit, 3, is the same in both numbers, so you need to look at the number in the tenths position to work out which number is smaller.
4 is smaller than 6, so 3.4 is smaller than 3.6.
Have a look at the slideshow below to see another example. This time four numbers need to be put in order from smallest to largest.
Print out the worksheet and cut out the monsters or draw your own monsters on squares of paper. Then complete the questions and add your monsters to the number line.
