SWBAT construct functions that model linear relationships, day 3.

Big Idea

Push kids to really interpret the meaning of slope and initial value in real-life contexts. This is tricky stuff, so kids need lots of practice.


10 minutes

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.

Today's warm-up #2 is a question that continues to push kids to interpret slope in different situations... it's worth ensuring that EVERY kid gets this correctly.  This might mean spending much less time on #1.

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.
