Vocabulary

 * Integer: A whole number (both positive and negative).
 * Number Line: a line marked periodically with numbers
 * Origin: Zero (0)

Lesson
An integer is any number, positive or negative, that does not have a fraction or  decimal point. Integers can be shown on a number line, like the one below.



This number line shows the numbers from -10 to (positive) 10. Notice the arrows on either side to show that the numbers continue in both directions even though they are not shown on the line.
