Addition and Subtraction Rich task!

Last week we used this rich task to see which addition strategies were the most efficient for winning a Gold, Silver or Bronze medal. Some of the children verbally justified their strategies, therefore this helped us as a group to make a decision on which strategies earned a Gold, Silver or Bronze medal. I will post a photo of our results tomorrow. I will use these results and strategies to find the add/sub goals for each student.
