Exploring Integers and Absolute Value

This video tutorial covers two main learning targets: graphing integers on a number line and finding the absolute value of expressions. It begins with an introduction to integers, explaining their placement on a number line and distinguishing between positive and negative numbers. The tutorial then demonstrates how to graph coordinates on a number line, followed by exercises on writing integers for various real-life situations. Finally, the concept of absolute value is introduced, with examples and practice problems to reinforce understanding.
