I have always liked row games as a way to have a more interactive worksheet. The idea is that you have two columns of questions and you pair students up. Each student chooses a column and does all the questions in that column. They check their answers by seeing if they get the same value for their questions that are in the same row (even though they are different questions). They take some time and planning to create so it's always great when someone makes one (or some). Here are some that I've made.

Anyone want to test a Row Game for me? 🤞 I don't trust my eyes anymore to find errors! 😬 I am hoping solutions in each level of the table match, enough info is given, and directions make sense. Thanks!#iteachmath #HRCEmathhttps://t.co/F3dxzqNRPH pic.twitter.com/3mMrwGyMcO

Year's ago we used to have a grade 12 math course where proofs were a fundamental part of the course. I loved that course. This would have been a good relationship for it.

This would have been another great question for that proof course from the past. But now you could use it in our grade 9 course when you talk about properties of numbers.
