Lesson 3
Comparing Proportional Relationships
Lesson Narrative
In this fourth lesson on proportional relationships, students expand on the work of the previous lesson by comparing 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.
Learning Goals
Teacher Facing
- 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).
