Understanding Absolute Value and Negative Numbers on a Number Line

This lesson explains the concept of absolute value using a number line. It highlights that as the value of a negative number decreases, its absolute value increases. The lesson addresses common misconceptions, such as confusing the size of negative numbers with their absolute values. Examples using money and a submarine illustrate how moving further from zero increases absolute value. A temperature comparison between New York and Chicago demonstrates how absolute value helps determine which city is colder. The lesson concludes by reinforcing the understanding of absolute value and its practical applications.
