Product Description
Standard 6.EE.6 - Use variables to write solving single variable expressions when solving a real-world or mathematical problem. (Equations are addressed in another lesson)

This introduction to writing simple expressions, and then more complex ones, begins with a focus to accurately represent relationships and gain confidence with identifying and defining suitable variables for unknown values. Once practiced, we can move on to represent more complex relationships. The method shown in the key (I call them expression bubbles) is set up as a springboard to writing equations.

This lesson includes:

Lesson 1 – Representing simple relationships (intro) with 2 lesson problems. Followed by practice problems.

I included two formats of the homework. Double-side both lessons or distribute separately.

Bar models is the way to go, but I did find expression bubbles to be a bit more intuitive. Draw a circle and label it with what the expression represents. Identify and define the variable and write the expression inside the bubble. Later, when students write equations, they can use the same method, identify the bubble with a variable and set the expression equal to that variable. They can also see that the bubble only exists because of what’s inside it. This thinking helps students identify independent and dependent variables.
