Sieve of Eratosthenes

Year 5 have been investigating properties of numbers. Today, children had to follow instructions using their knowledge of multiples to predict, identify patterns and explain their reasoning. 

After completing the investigation Kaitlyn and  Evelyn realised the numbers were Prime numbers. 
" We found out the numbers left in the grid are Prime numbers. Prime numbers have to be greater than one and can only be divided by itself and one" e.g 2, 3, 5, 7 



Bailey and Bethany recognised the prime numbers. They drew factor bugs to demonstrate the prime numbers. 

Miss Cooley decided to be a pupil in the class. We had to explain our reasoning to her.
