Unit 5, Lesson 3
Comparing Proportional Relationships
Accelerated 7
Preparation
Lesson Narrative
In this lesson students compare two situations that are represented in different ways. For example, one situation might specify a rate of change, while the other is represented by a table of values, a graph, or an equation. Students move flexibly between representations and consider how to find the information they need from each type. They respond to context-related questions that compare the two situations and solve problems with the information they’ve garnered from each representation (MP2).
- Compare the rates of change for two proportional relationships, given multiple representations.
- Interpret multiple representations of a proportional relationship in order to answer questions (in writing), and explain the solution method.
- Present a comparison of two proportional relationships (using words and multiple other representations).
Let’s compare proportional relationships.
