At St Helen's Primary school, pupils follow a progressive Maths Calculation Policy to ensure that pupils develop a secure understanding of key mathematical concepts. Our Maths Calculation policy can be found below: 

Maths Calculation Policy 22-23 

 We have created a range of short videos for parents/ carers to use to support children with using the different written methods at home. Children may also find it useful to use these videos as a short revison session for each method. 

Each video outlines at what stage children will be taught the method and gives step-by-step guidance to use the written method.
