Parents Evening Written Calculation Methods

Welcome
to
Greystoke Primary School
Maths calculation evening
Thank you for attending our KS2 maths information evening on formal
written methods.
This guide is intended to support parents of primary school children.
Obviously it would be impossible to set out in detail everything your
child would learn during KS2 , but by providing an outline of typical content and some background information about how formal written calculation methods are taught within school, hopefully it will help you support
your child in making the most of their maths education.
You will find in this booklet a guide on the formal written methods and
how they progress in each year group in KS2. As well as some ways you
can help your child at home and useful websites.
If you need any further help, please do not hesitate to speak to your
child’s class teacher or Mrs Roberts the maths co-ordinator.
