As part of our learning about prime and composite numbers, Year 5 played a game called ‘Prime Island’. Each person started off the game with their own island with a number inside. The number could be a composite number or a prime number. 

The children then ‘swam’ around in the water. When the whistle blew, Miss Allen called ‘shark attack’ and the children needed to swim to an island with a prime number inside. Only two people were allowed on each prime island! 

If you landed on a composite number you were allowed to stay in the game as long as you could explain why it was a composite number and give examples of the numbers factors.

We had lots of fun and no children were eaten by sharks by the end of the game which shows how well we know our prime and composite numbers!
