SWBAT determine the slope of linear functions from graphs.

Big Idea

Ah, good ol' rise over run - forever a classic. Introduce students to the concept of slope in this introductory lesson.


10 minutes

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 here.

In this case, the warm-up gives the chance for kids to determine whether the given point is a solution to the problem. 

In addition, question #2 - How many solutions does any linear function have? - spirals the idea that any linear function has an infinite number of solutions that will make the function true.  I make sure to use that language over and over so kids internalize it.

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.
