# Graph linear functions while solving for "y" first

Lesson 2 of 20

## Objective: SWBAT define and graph linear functions.

#### Warm-up

*10 min*

Each day, students complete a Warmup 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 gives the chance for kids to practice graphing from the previous day, in this case with a fractional coefficient for the slope. Ensuring this skill is solid is essential to success in today's lesson.

A few areas that I zero in on as a go over this problem and check for understanding:

- do students understand that the y-intercept is easily found on the coordinate grid?

- do students check that if the slope is positive, the line is sloping upward?

- can students handle fractional coefficients?

#### Homework

*15 min*

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

Great lesson. I like the fact you have the answers as well. I print those and post so students can check their work.
