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.


An important part of maths development has always been rote learning of certain maths facts. For many years this has included practising times tables and addition facts, such as numberbonds and doubles. Each half term children will be focusing on Key Instant Recall Facts (KIRFs) that will be taught in school but also need to be practised at home as well.


It is important that they know these facts thoroughly and can recall them 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. They benefit from knowing their KIRFs inside out, back to front and with instant recall.


The documents below explain each KIRF in more detail and give some tip tops for learning them.

Years 3 and 4 have a big focus on times tables. More information about this can be found here: Times Tables | St John's C of E Primary School (
