SWBAT solve problems involving linear functions flexibly.

Big Idea

Logic rules! Students apply everything they know about linear functions to solve problems flexibly. This is a lesson that brings a lot of different standards together, and pushes kids to be flexible and logical in their thinking.


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 here.

Today's warm-up pushes students to move flexibly between multiple representations of a given linear function.

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.
