Objective

SWBAT understand and apply slope-intercept form.

Big Idea

y = mx + b. The big ideas in 8th grade math don't get much bigger than this one. :) If I could make the font size in this section 1000 point, I would. This is HUGE!

Warm-up

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 not only gets kids to practice finding slope, it pushes conceptual understanding of horizontal lines.  I push the idea of "NO ROBOTS" - meaning that they can solve #2 without having to robotically apply the formula.  What should be the slope of a horizontal line?

Homework

15 minutes

The Homework 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.
