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.

I often use a "mixtape" approach that pushes the kids to see/review multiple types of problems - the cumulative effect of which can be really powerful.

Today's warm-up both reviews the previous day and then reaches back to linear functions for an additional review.
