Lessons tagged with "proportions"

This number sense lesson focuses on using proportions to solve problems. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the problem and identify the given ratio. Then, they set up a proportion using the given ratios, if necessary. Finally, they cross-multiply and solve for the unknown value by applying an inverse operation, and then they interpret the solution. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.

This 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 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).
