Lesson Summary:

In Absolute Value Part 2, students learn how to solve absolute value inequalities for the variable and graph the solution set on a number line. By finding the center and distance from the center to the boundary, students can write the absolute value expression that satisfies the inequality. Whether it's greater than, less than, or equal to, understanding the meaning of the inequality is crucial to solving these problems efficiently. Students will learn to draw the number line and shade in the solution set, making this a practical and relevant lesson for everyday math problems.

Lesson Description:

Solving absolute value inequalities for the variable and graphing the solution set on a number line.
