Free Y2 maths worksheet: Understand subtraction

This maths worksheet gives a little bit of practice with subtracting a single digit from a 2-digit number, keeping below 30. There is a number line to help.

There are a range of mental arithmetic strategies that can be used for these, depending on the numbers. For example 25 – 5 is straightforward, however 23 -6 could prove much trickier and the number line could be used in several ways.

Some children will just count back 6 to reach 17. Others might recognise that 6 is 3 + 3 so they take 3 to make 20 and then take another 3 to make 17.
