The purpose of this lesson is for students to practice extracting information about a context from representations that model the context. Then, to answer questions about a similar context given a model. This prepares students for the associated Algebra 1 lesson, where they will be answering similar questions with less scaffolding. Determining information about a context from a representation is an example of contextualizing (MP2) and is a crucial skill in modeling with mathematics (MP4).
- Compare different situations modeled by different representations.
- Extract information about a situation that is modeled by a quadratic function using different representations of the function.
- Let’s interpret tables, graphs, and equations.
Note that the tools for creating a visual display are only needed if you choose for students to use them to present their work in the last activity.
