This week we started work on formal written addition. We were using the column method where you have to lay your work out clearly. If you write the numbers in the wrong column then your answer will be incorrect.
At the beginning of the week we started with addition with no regrouping (1), then moved to addition with regrouping of ones (2) and then regrouping of tens (3). Some of us even worked on addition problems where we had to work out missing numbers , check using the inverse operation or answer questions presented in different ways (4). We are trying to get into the habit of estimating our answers first. This helps us to check whether our answer is reasonable when we have completed our calculation.
Mrs Sherwood was on hand to give us a bit of help if we got a bit stuck!
