Difference

Craig from Brookdale Primary gave this solution:

Perhaps you can find other ways of doing it?

Here is a solution that came in from a pupils in Stage 3 at Burke Ward Primary School, NSW Australia.

Thank you for that extra solution.

During the 2020 lockdown we had this sent in from a teacher who works at Woodmansterne Primary School, she wrote:

One of my newly-returned pupils has found another solution to the problem 'Difference' which we thought you'd like to see! She is called Melissa, and demonstrated excellent resilience with this problem. 

Thank you for that, well done Melissa, and thanks to the teacher for submitting it. It's a good solution.
