# Lesson 14

Interpreting Representations

These materials, when encountered before Algebra 1, Unit 6, Lesson 14 support success in that lesson.

### Lesson Narrative

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).

### Learning Goals

Teacher Facing

- 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.

### Student Facing

- Let’s interpret tables, graphs, and equations.
