The associated Algebra 1 lesson is about making sense of the features of a graph that represents a situation. In this supporting lesson, students consider multiple possible graphs to represent a situation, choose one that represents it the best, attending to reasonable values for the domain, and explain why. This work requires reasoning abstractly and quantitatively (MP2) as well as attending to precision (MP6).
Lesson overview
- 7.1 Warm-up: Possible Rectangles (10 minutes)
- 7.2 Activity: Which Graph Represents It the Best? (15 minutes)
- 7.3 Activity: Refining the Representation (15 minutes)
Learning goals:
- Consider reasonable values for the domain of a function that represents a context.
- Make sense of points on a graph that represents a context.
Learning goals (student facing):
- Let’s represent situations precisely.
