Standards: HSA-APR.A.1 MP1 MP2 MP6 MP7
Subject(s): Math
60 minutes
1 Warm-up - 10 minutes

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.
