Solve for Absolute Value by Plotting Each Value on a Number Line

The video tutorial explains the concept of absolute value as the distance a number is from zero on a number line, emphasizing that it is always positive. It uses real-world examples, such as David and Mary stepping on a chalk line and Jonathan and Sam walking blocks, to illustrate how absolute value works. The tutorial includes a practice problem with Susan and Tessa driving miles to reinforce understanding. The lesson concludes by encouraging students to solve absolute value problems using a number line.
