This is an activity to review percents and proportions.
Print and laminate if desired and cut out each rectangle. Hand out to students and provide them a time limit of roughly 1 - 1.5 minutes to complete the problem. They rotate the cards once the timer goes off. They can work with partners.
Starred problems are more difficult.
Students will need to determine tax, tip, and discount. They will also need to know how to convert rates and find unit rate.
