KIRFs (Key Instant Recall Facts)
At Greenside, we promote the learning of 'Key Instant Recall Facts' (K.I.R.F Targets) to support pupils' maths learning across the school. These are maths objectives, taken from The National Curriculum, which children working at age-related expectations should be able to mentally calculate and recall accurately and rapidly. Each year group has one or two different objectives every half term, which will be practised regularly in class and may be reinforced through the weekly homework activity.
You may like to practise your child’s K.I.R.F’s at home to support them in improving their recall ability and we have posted a yearly overview below. Additionally, all year groups will communicate their current KIRF target with parents/carers on their half-termly newsletter as reminder of their current focus. We encourage all children to learn these key facts as they can then be used to support further learning and aid problem-solving in maths.
