This is an activity that gets students out of their seats and interacting with each other. Each student is given a card with a ratio on it. They must pair up with a partner and solve the proportion their two ratios make. They repeat this process with 5 other students. This activity involves includes quadratic equations. I have included a set of 30 Ratio Cards and a student worksheet.
Prep: just print and cut out the Ratio Cards ahead of time.
