Subtraction Strategies

We have been doing some great work exploring subtraction.  We have solved equations, solved & written subtraction stories and explored different strategies.  To solve an equation like 56 – 23, some of us have really like using the number chart to help us count back the tens and then the ones. You could print your own chart at home: hundredscharts and show mum or dad how you can do this.

We have also tried out what we have called the “jump back” strategy.

Can you explain how this works to your mum or dad? Remember that it is important to think about how to break up the ones number into two useful parts… This is the most important trick of this strategy being a quicker way to jump back over a bridging number.

We are now moving onto a new Maths unit.  It would be a good idea to keep trying to get faster at recalling subtraction facts to ten and under twenty.  For example trying to build more KNOWN FACTS.  Do you straight away know the answer to: 5-3, 9-4, 12-3, 15-5, 6-2, and so on?
