3. Introduction
This policy is to provide parents with a clear guide to how written calculations are taught in Valley Gardens Middle School so they may confidently support their children at home.
Currently only formal written methods are covered, but the policy will be extended to the progression of mental methods and strategies.
This is a working document and will be updated throughout the year.
