I was introduced to row games while reading Kate Nowak's blog several years ago. A row game is an activity for a pair of students to work on together. Problems are organized in two columns. The first student completes all of the problems in column A and the second student completes all of the problems in column B. The questions in each column are different but the answers are the same. Students collaborate to verify that their answers match. If they do, they move on to the next question. If the answers do not match, the students work together to find out where the error was made and how to fix it. This allows students to have immediate feedback on their work. It also generates great discussions between students as they check each other's work. Another benefit is that students can correct each other's computational errors and the teacher's time can be focused on helping students with more serious comprehension errors.
Row Game Links
There are a couple of great resources for row games online. Kate Nowak has a shared Google drive folder packed with mathematical row games for a variety of grade levels and topics. Another row game collection is available on John Scammell's Orchestrated Experiences for High School Math website.
Nova Scotia Mathematics 10 Cumulative Review Row Game
Below is a row game that I created as a cumulative review for Mathematics 10. I created about half of the questions myself and appropriated the rest from row games created by Kate Nowak, John Scammell, and David McGuinness.
