2. *An integer is the set of whole numbers and
their opposites.
*In other words, integers are positive (+) and
negative (-) whole numbers.
*Examples of integers include:
12 7 -10 -125 18 -30,843

3. *Fractions and decimals are NOT integers. Those
are rational numbers.
*Integers are whole numbers!

4. *Let’s look at integers on a number line.
*Plot the integers 1, -9, -4, and 7 on the number
line.

6. Compare the following integers. Use <, =, or >.
Try drawing a number line to help you visualize the integers!
0 ___ 10 -5 ___ 15 5 ___ -15
0 ___ -20 -8 ___ 8 -6 ___ 6

7. Order the following integers from least to greatest
-4 3 2 0

8. For this problem, we are working with -4, 3, 2, 0

10. *Least to greatest is left to right.
*Greatest to least is right to left.
*Our answer should be -4, 0, 2, 3.

11. *The absolute value of a number is distance it
is away from zero on the number line.
*We show absolute value like this: |-2|
*Absolute values are always positive because
the signify the distance from zero on the
number line!
*|-2| = 2

12. 1. Order these temperatures from least to greatest:
0°F, 115°F, -15°F, -32°F, -40°F, 113°F
2. Compare. Use <, =, or >.
0 ___ -20 |-8| ___ 8 -6 ___ 6
3. Estimate values for points A – E.
A B C D E
