Combining the skills from the previous videos, particularly inequalities and absolute values, Sal works to solve several new sample problems. He encourages watching the video "over and over," which is a good piece of advice for mathematicians of any skill level.
Several examples of positive and negative numbers in their absolute value are plotted on a number line.
Sal reviews absolute value equations by taking viewers through a careful and deliberate problem-solving process. Those who didn't thoroughly understand absolute value during class will appreciate Sal's steady and straightforward instruction.
This lesson demonstrates how to solve an absolute value equation, keeping in mind there are two possible answers.
Solving a simple absolute value equation.
Sal unravels the mystery of absolute value. This presentation contains well-defined and clearly explained examples that build upon each other to provide a strong foundation for solving equations that contain absolute value. This would be a wonderful compliment to any lesson or as extra support for struggling learners.

A teacher's guide precedes the five-page activity on solving absolute value problems. A summary, essential question, launch and exploration activities are suggested to go along with the assignment. You might want to know that the activity itself, while pertinent to the skills of solving and graphing absolute value problems on a number line, is dry; there are no real-life applications.
The skill set for this lesson is to have learners use tables to generate functions and functions to generate graphs. They work through a series of worksheets with the instructor to determine absolute value, domain, x and y intercept and complete transformations. All of the necessary worksheets and a homework assignment is included.
Solving a simple absolute value equation.
What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and minimum values in the graph.  This two-page worksheet contains detailed notes, examples, and instruction, as well as four problems.
Connect absolute value to distance when two points are plotted with the same x or y value. The video reviews graphing and common mistakes when plotting points. Learners will see that you can find the absolute value of the x or y coordinates when the other coordinates are the same. Video is third in a seven-part series about graphing and coordinates. 
High schoolers solve absolute value equations graphically and using tables.  In this solving absolute value equations graphically and using tables lesson, students compare linear equations with absolute value equations.  High schoolers verify solutions to absolute value equations using a graph.  Students solve absolute value equations with one and no solutions.
Learners identify where in the real world absolute values are used. In this algebra lesson, students find the range of values and solve inequality and absolute value problems.
Learners explore the concept of absolute value functions.  In this absolute value functions lesson plan, students determine the difference in temperature from daily temperature and the average temperature for a given month.  Learners plot the data using a scatter plot and find a function to model the data.
Translate an absolute value equation, horizontally and vertically. First, what is the form of an absolute value equation? There are several variables that represent specific pieces in this equation. Vertical, horizontal, constant, vertex, and rays are terms to be identified. Watch this video closely and take notes as the teacher explains the steps. And then maybe, watch it again.
As long as you keep in mind that there is no such thing as negative distance, then you will know the meaning of absolute value.
There are several rules to adding integers using absolute values. It can seem a bit overwhelming to remember these rules. Watch this video and learn the rules as the instructor illustrates a few examples and explains the steps involved.
High schoolers discuss the definition of absolute value, and view examples of absolute value equations. They use a calculator to evaluate absolute value expressions and complete a worksheet.
In this absolute value worksheet, students find the correct equations and inequalities for absolute value. Students complete 18 problems.
