Comparing & Ordering Integers
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).
Finding Absolute Value
Find the l3l and l-3l.
l3l and l-3l = 3
Quick Practice
Write the opposite of each number.
a) 2
b) 4
c) -3
d) -11
a) -2
b) -4
c) 3
d) 11
Quick Practice
Find each absolute value.
a) l-21l
b)l14l
c) l-1l
d)l21l
a) 21
b)14
c) 1
d)21
Comparing Integers
Compare -4 and 1 using <, =, or >.
Remember, numbers increase going from left to right.
-4 < 1
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
Quick Check
Compare using <, =, or >.
a) -6 -3 b) -23 0
a) -6 < -3 b) -23 < 0
e) l-21l 21
e) l-21l = 21
c) 17 -18
c) 17 > -18
f) -14 l14l
f) -14 < l14l
d) 5 -1
d) 5 > -1
c) l-1l -5
c) l-1l > -5
l-4l > l-3l
l12l
= l-12l
l-20l >

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
