#### 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 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?
