# Define and graph linear functions

Lesson 1 of 20

## Objective: SWBAT define and graph linear functions

#### Warm-up

*10 min*

Each day, students complete a Warm-up that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

For a video narrative about how I structure each lesson, and how the warm-up fits in, click Warm Up.

In this case, the warm-up addresses a problem that many students missed on the last unit assessment. Only one of them has a negative slope... and so the question I ask to open is:

"In which of these cases should there be a positive slope?" We then analyze the incorrect answer choices to finally arrive at the correct answer choice, a strategy I often use.

Because students often have only an emerging understanding that positive slopes represent a positive association (in other words, as x increases, y increases also) - this is a wonderful learning opportunity to continue to develop this understanding.

#### Homework

*15 min*

The homework file is a resource that generally includes 5-7 problems that include questions related to this lesson, as well as spiraled review. I also give the kids the answers to all the problems.
