By the end of this tutorial students will be able to solve absolute value inequalities with one variable
Students will be able to graph absolute value inequalities on a number line using the two solution inequalities
This tutorial introduces students to solving absolute value inequalities following four simple steps:
1) Balance so the absolute value is alone
2) Write two inequalities (a positive absolute value and negative absolute value equation)
3) Balance the inequalities
4) Check your solution by substitution and/or number line
The tutorial uses a handful of examples to demonstrate the steps.
Watch the video and/or slides and take notes
Use your notes, steps, and examples to help you complete the class practice.
This podcast introduces students to solving single variable absolute value inequalities and checking the solution inequalities using substitution and number lines.
