We have spent a lot of time this week working on the addition strategy using doubles. The students have been playing games all week to increase their fact fluency when they are faced with a doubles problem. We played doubles bump and doubles tic-tac-toe as well as challenged a friend while working on our speed in answering doubles facts. We even identified the pattern that appears when you list the doubles facts...all of the answers are even and they skip count by 2!
