During our latest "Math Talk," I was amazed at all of the different strategies being used. I presented a problem, students solved using mental math, then shared their answers. (Their answers are written on the left.) We first observe all the different answers. What do we notice? Look at the tens place. Look at the ones place. Are any of the answers close to each other? Do any stand out?
Then partners turn and talk. They share their strategies. Many of them realize if/how they made a mistake just by talking it out. Then students share their strategies while I record it on the board (to put a visual to the mental math strategy).
