Today, in grade 9, we did some problem solving practice, in a new format.
We had a long row of desks, and we worked with our partner across the table. We used our formula sheets, and strategized to solve optimization questions, or composite volume problems, or pythagorean theorem problems.
After all problems are adequately solved, one side of the table is named the “experts”, and they stay put, while the other side stands and shifts to their right. They, the newcomers to the problem, will do the problem, with the support of the expert if needed. 
The newcomer then is named the expert, and they stay put, while the other side, stands and shifts to their right, creating a new partnership.
This reciprocal teaching/review method works well for many activities. We’ll be doing it again regularly.
