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 produce a “Tip Sheet” each half term on that term’s particular objective. This tip sheet will provide further ideas on how you might practise these skills and online resources and games, which provide further support.
At Greenside, 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.
