Pre-Algebra Lesson #3 Inequalities and the Number Line | Greater Than Less Than

In this lesson, we will continue to work with the whole numbers and introduce the concept of a number line. We will use the number line to visually see that numbers increase as we move right and decrease as we move left. We will then introduce the less than and greater than symbols and look at some related problems.
