# Maths Calculation Methods - Video Demonstrations

With a lot of help from one of our Governors, Colin, we have created videos to demonstrate the main calculation strategies children use in our school. These will help parents when supporting their children in maths.

We are in the process of creating more and will load them on this page as they are completed. We hope you find them useful. Thank you Colin!
