Year 5 have been learning about composite and prime numbers. A prime number is a number that only has two factors: 1 and itself. A composite number has more than two factors. 

We played a game where we had to run outside and when the whistle blew, Miss Allen called out instructions. She started by calling out ‘prime’ or ‘composite’. We needed to run to a number that matched her instruction. When we landed on that number we had to complete that number of star jumps! Jackson chose 29 as his prime number so had to do 29 star jumps! Avyukt chose 17! No one landed on the number 1 because 1 is not a prime number because it only has 1 factor. 

We then extended our game to finding multiples and factors. By the end of the session we had consolidated our understanding of prime and composite numbers as well as getting out of breath!
