This is a great and engaging activity for 7th graders! They have to create a store and items they want to sell. The prices they come up with, but I also provided some. They have to then find the discount for 3-5 items (based on their level) and markup for 3-5 items (based on their level). It is an easy way to apply the skills and see if they really understand what discount and markups are. They love being creative and don't even realize they are doing math at times! Successful!
