Multiplication and Division Calculation Policy
February 2015
MULTIPLICATION AND DIVISION CALCULATION POLICY

Children should be confident in using a range of mental calculation strategies (see mental calculation policy) and informal written
methods, before they are ready for formal written calculations

Mental calculation strategies should continue to be taught alongside formal written methods. At all stages of progression, a child should
be able to choose whether a calculation requires a mental or written strategy and what will be most efficient

Teaching informal written methods, such as how to use an empty number line, should provide a model for children to develop a mental
strategy

Teachers should plan to teach calculation strategies and then give a wide range of opportunities for children to apply the
strategy in problem solving contexts

Times tables should be taught everyday from Year 2 onwards either as part of a mental oral starter or at other times as
appropriate within the day
National curriculum expectations
Year 2 - 2,5,10 times tables
Year 3 – 3,4,8 times tables
Year 4 – all multiplication and division facts up to 12 x 12

Objective from the National Curriculum
solve one-step problems involving multiplication
and division, by calculating the answer using
concrete objects, pictorial representations and
arrays with the support of the teacher.
Ways in which children calculate this
Using pictures and symbols
Children should have opportunities through play to
understand and experience division in terms of
Sharing – ‘one for you, one for me…’
Grouping – ‘let’s put three apples on each plate’
Sharing
6 sweets are shared between 2 people. How many do they have each?
Learning Intentions
To be able to divide by sharing objects
