Lessons tagged with "cross+multiply"

This algebra and functions lesson focuses on solving problems involving rates. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the problem, identifying the given rate and the given and unknown quantities of the other rate. Then, they set up the proportion and solve it by cross-multiplying. Finally, they interpret the solution. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
