What is
the Big Number Crunch?
The Big Number Crunch was designed to improve calculation
skills at St Joseph’s. It has broken down levels (or steps) of calculation in order
to see and promote progression.
Each child will have an addition, subtraction,
multiplication and division target. These targets are taken from the steps of
calculation.
E.g. In year 6 one child has the following targets:
Addition – step 9 Subtraction –step 10
Multiplication – step 8 Division
– step 7
