Lessons tagged with "inverse"

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 compute unit rates (complex fraction ratios). The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students create an equivalent ratio table using given units and quantities. They identify the unit quantity, determine the multiplicative inverse which produces one, and then apply the multiplicative inverse to the other quantity. Finally, they interpret the unit rate.
