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 watch my Lesson Structure video.

In today's warm-up, I wanted to re-focus on standards that are outside of the 8th grade common core, but part of the Algebra I standards. The tasks have progressed in difficulty over the last two days, which lends itself nicely to both review and extension as each day passes.
