Kelsale Maths Calculation Policy

The 'Kelsale Maths Calculation Policy' demonstrates how we teach Mathematics at Kelsale to enable parents and guardians to help with Maths at home.

End of Year Arithmetic Expectations

Our 'End of Year Arithmetic Expectations' outlines the addition and subtraction objectives and strategies that the children should learn by the end of their year group.

Below are videos which demonstrate the formal written methods to calculate the four operations: addition, subtraction, multiplication and division.

You will find these written methods in the abstract section of our calculation policy. These written methods should only be used once your child has mastered the concrete and pictorial representations shown in the calculation policy.
