Another method involves the use of a number line. The number line can be drawn to give us a visual representation of the whole numbers. We can use this number line to compare the size of two or more whole numbers. We will find that as we move right on the number line, our numbers are increasing in value. As we move left on the number line, our numbers are decreasing in value. We will learn how to use our number line to show the relationship between two whole numbers using the inequality symbols (less than <) and (greater than >).
