Reflection: Student Communication Doubles & Doubles +1 Practice - Section 1: Number Work


Well, this section didn't go quite the way I planned.  There wasn't anyone who stood out with a strategy to find a partner.  So after about 1 or 2 minutes I had everyone stand in a circle and I asked them if there was anything they noticed about some of the equations?  Someone did say, "some of them are doubles."  YES!!  We are onto something here.

I said raise your hand if you have a double.  I told them doubles could not be partners.  Can you find your partner now?  In less then 30 seconds I saw the light bulbs go off.  They figured out they were doubles and doubles +1 partners.

We then shared out all partners.  I took a bit longer with the share out because I wanted to hit home the connection between the doubles and doubles +1 equations.
