This terms KIRF is to recall addition and subtraction facts for numbers within 20 and to use related facts to 100. To help practise this KIRF we would like your child to complete the missing numbers on the bar models below. We will start by learning number facts to 10, 20 and 100. Even if your child already knows these facts, they need to practise them so that they are fluent. This means they should be able to recall them without writing anything down. The more practise, the better! The Hit the Button game on Topmarks is a great way to practise. Hit the Button - Quick fire maths practise for 6-11 year olds (topmarks.co.uk)
