This set of 12 task cards will help students review three of the four indicators of common core standard 7.PR.2. Students will be setting up and solving proportions, proving if two variables are proportional (PR.2.a, PR.2.d) and finding unit rate (PR.2.b). The format of task cards allows for many different activities, allowing for student differentiation. I have included how I used these task cards in my classroom and I’ve added a few extra ideas that would be fun to try. As a bonus I listed a few classroom management tips to make this activity fun for everyone!
