Topic 4.14

To review navigating the two hundreds chart we played a relay game. I drew three grids on the board. (Tic Tac Toe style) Each one had only number filled in. I divided the class into three teams. The first team to successfully fill in their grid won. We played three or four times and the children got better and faster at filling in the grid. They started to see the patterns. The teams were allowed to help teammates so that a struggling child was not embarrassed if he/she still didn't quite get it. This was a simple to construct and play game that didn't require any laminating! Please feel free to email me if my explanation was not clear.

Consolidating and Prioritizing Lessons

I found the overview of math lessons very helpful. It has been somewhat stressful to look at what is left to teach and how little time is left to get it all in. I am curious to know why we can skip all of Topic 12 if we run out of time. In prior years the addition and subtraction taught in Topic 12 was the main work of the second grade. Is this now a third grade skill and we are only exposing students to the beginning mechanics? Regrouping in subtraction is lesson 12.10. I know that our students will need to know how to regroup on the third grade CMTs. How will this impact the third grade teachers who will now have to take on the majority of the teaching of regrouping? I understand that second graders are exposed to the concepts needed to be good math thinkers and maybe the transition to paper pencil tasks will be very easy for them. Is anyone else teaching regrouping (supplementing)?
