Classroom Ideas

A fun game to play to consolidate multiples of three is 'Fizz buzz'. Children sit in a circle counting consecutive numbers, but replacing multiples of three with the word 'fizz' and multiples of ten with the word 'buzz'. If they forget to replace the multiples with words, they are out of the game! A support activity to help children learn the multiples of three is to colour them in on a hundred square. Once pupils are more confident, they could use Venn diagrams to sort numbers into multiples of three, multiples of ten and those that are both.
