Add and subtract polynomials

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.

For a video narrative about how I structure each lesson, and how the warm-up fits in watch my Lesson Structure video.

In today's warm-up, I wanted to re-focus on standards that are outside of the 8th grade common core, but part of the Algebra I standards - and so these tasks are meant to be quick refreshers on some algebraic work - properties, using algebra to represent a context, using an equation to describe a line.  They are also meant to be confidence-boosting as we re-enter the world of preparing the kids for high school algebra.

HW138 Add and subtract polynomials provides the students with the opportunity to practice the skills covered in class today and check their work using the answers provided.
