Lesson 5.3
Compare and Order Integers
Compare and Order Integers
Objective: To understand how to compare
and order integers.
Compare and Order Integers
At the end of this lesson you should be able
to answer the following question.
How can symbols and absolute value help you
order sets of integers?
Integers
The number line can be used to compare
and order integers. On a number line, the
number to the left is always less than the
number to the right.
Integers
An inequality is when two values are not
equal.
e.g. 6 > 3
Integers
Write -9 and -4 as an inequality.
Integers
Write -9 and -4 as an inequality.
-9
-4
-9 < -4
Generally you want to keep the integers in
the same order as in the question.
Integers
Write -5 and 0 as an inequality.
Integers
Write -5 and 0 as an inequality.
-5
-5 < 0
0
Integers
Replace with < or > to make the statement
true.
-6 5
-5
0
Integers
Replace with < or > to make the statement
true.
-6 5
-5
0
Since -6 is to the left of 5 it is less than 5.
-6 < 5
Integers
Replace with < or > to make the statement
true.
-1 0
-5
0
Integers
Replace with < or > to make the statement
true.
-1 0
-5
0
Since -1 is to the left of 0 it is less than 0.
-1 < 0

Justin has a score of -4 on the Trueville Trivia game.
Desiree’s score is -5. Write an inequality to compare
the scores. Who has the higher score?

-4 > -5
Integers
Justin has a score of -4 on the Trueville Trivia game.
Desiree’s score is -5. Write an inequality to compare
the scores. Who has the higher score?
-4 > -5
-4 is further to the right than -5, so Justin
has the higher score.
Integers
The temperature on Tuesday was 2˚F. The
temperature on Wednesday was -2˚F. Write and
inequality to compare the temperatures. Explain the
meaning of the inequality.

inequality to compare the temperatures. Explain the
meaning of the inequality.
2 > -2
2 is further to the right than -2, so
Tuesday’s temperature was higher.

The table shows the amount of time it takes Henry to do
different activities before going to soccer practice. If he needs
to be at practice at 8:15AM, what time should he wake up in
the morning?
Or you could have added the
times in the table,
15 + 35 + 10 + 20 = 80 minutes
Then figure out what time is 80
minutes before 8:15.
80 minutes is 1 hour and 2o minutes.
An hour before 8:15AM is 7:15. 20 minutes before that is
6:55AM
