## Objective

SWBAT solve equations with variables on both sides.

#### Big Idea

Let kids become the kings/queens of Algebra Land by declaring which side of the equation is Variable Land and which side is Constant Land.

## Warm-up

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.

It's incredibly important to push application to real-world contexts, especially in the midst of a fairly "procedural" unit like solving equations.  What does it actually MEAN when we solve an equation like this?  I use the warm-ups each day - which I go over meticulously while the kids are fresh - to try to keep this at the forefront of students' minds.

That's why there are a series of application like algebra problems (like #2) that are important to make sure you go over in detail.  I like using these problems to model the commutative property, also - there is more than one correct way to represent this equation.

The homework includes questions related to this lesson, as well as spiraled review.  I also provide answers to the problems on page 2.
