Combining Opposite Rational Numbers to Make Zero on a Number Line

In this lesson, students will learn how to use a number line to show that opposite rational numbers combine to make zero. They will understand that rational numbers include integers and can be expressed as fractions. Through real-life examples, such as earning and spending money or diving and resurfacing, students will grasp the concept of opposites and how they result in a sum of zero. This lesson will provide a visual and practical understanding of rational numbers and their relationship to zero.
