1. Comparing & Ordering Integers

2. Vocabulary integers: all positive and negative whole numbers and zero.
opposites: two numbers that are the same distance from zero on the number line, but in opposite directions. Ex. 2, -2
absolute value: a number’s distance from zero on the number line (always a positive value).

3. Finding Absolute Value
Find the l3l and l-3l.
l3l and l-3l = 3

4. Quick Practice Write the opposite of each number. 2 b) 4 c) -3 d) -11
2 b) 4 c) -3 d) -11
a) -2 b) -4 c) 3 d) 11

5. Quick Practice Find each absolute value. l-21l b)l14l c) l-1l d)l21l
a) 21 b)14 c) 1 d)21

6. Comparing Integers Compare -4 and 1 using <, =, or >. -4 < 1
Remember, numbers increase going from left to right.
-4 < 1

7. Quick Practice
Which number in the pair is farther away from zero. a) 4, -5 b) 2, 5 c) -1, -3 d) -12, 11 a) -5 b) 5 c) -3 d) -12

8. Quick Check
Compare using <, =, or >. a) b) c) d) 5 -1 a) -6 < -3 b) -23 < 0 c) 17 > -18 d) 5 > -1 e) l-21l 21 f) -14 l14l c) l-1l -5 e) l-21l = 21 f) -14 < l14l c) l-1l > -5

19. Ordering Integers
Order the numbers -8, 7, -4, and 3 from least to greatest. Use a number line to plot the points. Then put them in order from least to greatest.
Remember, numbers increase going from left to right.
-8, -4, 3, and 7
