### PRODUCT DESCRIPTION

Inequalities with one variable are hard enough for students to grasp, but add another variable and their brains go a little haywire! I wrote this lesson to make sure I could keep my 8th graders' attention while teaching a new and rather difficult concept.

What better way than through their tummies! ;-)

The lesson covers writing an inequality from a trip to a fast food restaurant with your friends. After writing the inequality, the students should discuss the parts of their inequality and how they came up with it. The graphing portion involves x and y intercepts and slope-intercept form. The PowerPoint covers graphing by hand and with a CASIO graphing calculator. The students discuss what the graphs say and how to determine solutions.
The lesson involves two different scenarios with ample time to share, practice, and reflect with a little bit of humor to boot!

The file contains a detailed PowerPoint (26 slides) with animations, brain breaks, videos, and opportunities to practice. I use the PowerPoint on my Smart Board so I can have students show how to rearrange equations and graph. With the PowerPoint, I'm providing guided notes with key. After the review, I also provide an opportunity to practice or HOMEWORK. (8 pages total)

I used this with my 8th grade Algebra I students, but it is easily modified for younger or older students. It makes a great introduction or review of inequalities with two variables. I've used it several times for Common Core Tasks and the kids LOVE it!

ENJOY.
