Cranbourne Primary School

Where Learning and Friendships Grow


To develop the childrens fluency and mental maths skills, we have introduced Key Instant Recall Facts (KIRFs) throughout the school.  KIRFs support children in embedding the key number facts that underpin much of their mathematical learning including written calculations and problem solving.


Knowing number facts such as number bonds and times tables by heart, builds mathematical fluency and agility. These number facts need constant practise and rehearsal, so that children can recall them quickly and accurately.


Each half term, the children will focus on one Key Instant Recall Fact (KIRF) to learn at home.  These will be sent home at the beginning of each half term and can also be found on our school website. The KIRFs include practical ideas to assist your child in grasping the key facts and contain helpful suggestions of ways in which you could make this learning interesting and relevant. They are not designed to be a time-consuming task and can be practised anywhere including in the car or walking to school. Regular practise, little and often, helps children to retain these facts and keep their skills sharp. Throughout the half term, the KIRFs will also be practised in school and your child’s teacher will assess if your child is retaining these through a weekly ‘beat the clock’ challenge.
