SWBAT determine slope when given two points.

Big Idea

How do I find the slope when I don't have a graph? Is there a different way to find rise over run? Another good ol' classic -- the slope formula.

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 not only gets kids to practice finding slope, it brings back graphing of special cases -- the horizontal (y = a) and vertical (x = a) lines.  I find that kids need a lot of practice seeing these over the course of several days to beomce fluent in this.

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.  

Sometimes, the HW file is a take home assessment: 4 - 5 HW44 Determine slope from a table of values or two points.
