# Variables on both sides (Day 1 of 2)

Lesson 5 of 16

## Objective: SWBAT solve equations with variables on both sides.

#### Warm-up

*10 min*

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.

#### Homework

*15 min*

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