Addition and Subtraction Challenge


Hi everyone!

This weeks homework is to challenge Ms Cosgriff with the trickiest maths problems that you can using addition and subtraction skills. You MUST be able to solve the problem yourself though as Ms Cosgriff may need you to help her with the answers!!!!

Have fun! I will look forward to being challenged!!!
