Amazing Maths

This week my maths goal was to use a broad range of mental strategies to solve addition and subtraction problems. I had to show my learning of place value, tidy numbers and reversibility. The easiest question was probably place value because, we had to add the hundreds together, the tens together and the ones together. The hardest question was probably the reversibility because it was complicated to understand. Tidy numbers was okay because if you had to do 147 + 223 you only need to plus 3 to 147 and minus 3 from 223, so it has a zero at the end.
