8 Strategies That Will Make Subtraction Easy

Do you spend a lot of time teaching the addition strategies but a lot less time on subtraction?

No matter what country you teach in,  you will find a mathematics standard that says something like, ‘Fluently add and subtract within 20 using mental math strategies’. This means we need kids to have automatic recall of both their addition and subtraction facts.

 

Teaching a range of subtraction strategies is important if we want kids to have mastery over the subtraction facts to 20.

Subtraction Strategies

The main strategy for teaching the subtraction facts is to have children relate them to known addition facts. Of course, this means that the addition facts must be well known before attempting to teach the subtraction facts.

When children understand the relationship between addition and subtraction they will find it easier to master their subtraction facts. We can do this by introducing children to the think addition strategy – “I know that 3 + 4 is 7 so 7 – 4 is 3.” Teaching children about number fact families is the perfect way to show this link.

But it’s important that children are not reliant on only one strategy and that we teach them a range of strategies that they can use.

You will find that many facts will also have more that one strategy to use. 10 -3 is both a count back and take from ten facts; 7 – 4 is both a near doubles subtraction fact and a count up fact. Children should always use the strategy that is easiest for them and this might even just be using the think addition strategy.
