This Common Core ratios and proportional relationships lesson covers how to solve multistep percent problems using proportions. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students determine what the question is asking, and then the corresponding percent and quantity by drawing a diagram. Then, they set up a proportion for the percent and quantity, cross multiply, and solve for the unknown quantity. Finally, they interpret the solution, identifying whether it was a percent increase (tax, tip, or markup) or a percent decrease (sale, discount, or coupon). In addition to the lesson, there are four pages of Independent Practice with questions modeled after the Common Core assessment items.
