KIRFs (Key Instant Recall Facts) are designed to support the development of the mental skills that underpin much of the maths work in schools. They are particularly useful when calculating, be it adding, subtracting, multiplying or dividing. 

Each half term children are given Key Instant Recall Facts (KIRFs) to practise and learn at home as well as the work in school. These are sent home on A4 sheets and include practical ideas for parents/helpers to assist children in grasping the key facts. It is important that they know these thoroughly and can recall specific facts instantly.  

Whilst children have a wide range of abilities in mathematics, the KIRFs are designed to be a set of facts that need to be learnt thoroughly as they build on each other year on year. Again, we stress that the children must aim to know their KIRF inside out, back to front and with instant recall.
