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.
For a video narrative about how I structure each lesson, and how the warm-up fits in, click Warm UP.
Occasionally, I use a quick warm-up on test days to "pre-test" students on concepts that they might be shaky on, as one last way to solidify their understanding. They are based on previous year's data and my own analysis of the most common misunderstandings, and provide a much better assessment and review than, "so, before the test, are there any questions?"
The homework file is a resource that generally includes 5-7 problems, some of which are related to the day's lesson, as well as spiraled review of previous lessons. I also give the kids the answers to all the problems.
Sometimes, the HW file is a take-home assessment.
