Linear and Absolute Value Systems
This activity is designed to help students with solving nonlinear systems of inequalities by graphing.
>> Systems included both linear/absolute value and 2 absolute value inequalities.
>> Linear inequalities mostly in standard form.
>> Absolute Value Inequalities are in the form y>a|x-h|+k , y>|ax-ah|+k, |y|>x, |y|>c
This activity also gets students up and about. Place the 12 cards on the wall around your room. Students pick any card to begin with. They should graph the functions on the bottom of the page. After graphing on their own paper, students look around the room for a graph that matches theirs. Then they graph the next problem. They should continue until they return to the card they started with.
Included are 2 versions of this activity.
• One with 12 cards for use as a walk-around activity (includes an absent student version with all the graphs printed on 2 pages)
• A shorter version with only 6 cards great for table work, bell work or use as a review
To help with grading, I have included 2 student answer sheets: One that includes graph paper, and another with just boxes. Also included is a detailed key.
- Mid-Lesson or End of Lesson Check for understanding
- Math Station for students that have finished work early
- Test Review
- Homework Alternative
- Bell work
