7.RP.3 Use proportional relationships to solve multi-step ratio and percent problems.
According Common Core Standards for the 7th grade math curriculum, students need to be able to understand simple interest, tax, mark-ups, mark-downs, gratuities, commissions, fees, percent increase, percent decrease, and percent error. These skills relate very well and easily to real life scenarios! I like designing projects in which students solve problems they may be faced with in the near future. Having to save for a high ticket item may be something middle school students will be faced with in the near future.
