Regrouping in Subtraction
We have stared topic 9, which focuses on regrouping in subtraction of 2-digit numbers. We brought out our "trusty" workmats to be able to create a physical representation of the steps in our problem. The kiddos are still struggling a little with this concept, but yesterday was our first day so I know we will have a lot of "ah-ha" moments in the days to come!
