Each day, students complete a warm-up 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.
Today's warmup gives students the opportunity to recall and use their knowledge of the definition of a function.
The homework file is a resource that generally includes 5-7 problems that include questions related to this lesson, as well as spiraled review. I also give the kids the answers to all the problems.

Sometimes, the HW file is a take-home assessment.
