We have made a video to explain some of the mental strategies you can use for adding mentally. It is now added to the P5 Maths Channel where there are lots of videos about number at the P5 stage. This is quite a useful way of revising how to work things out in number and helps parents understand how we do it too. We hope you enjoy the video and find it useful. Explaining how to do something always helps us with our thinking when we are learning something new.
