TEKS Objective
6.1c
 Students will use integers to represent reallife situations.

Purpose

The learner will
synthesize negative
numbers and positive
numbers into daily
life.
Have you ever sacked the quarterback? Have
you ever seen a pass completed for 50 yards?

That’s using Integers!
Integers




Integers are positive and negative numbers.
Positive numbers are greater than zero on a
number line. Ex: ½, 1, 99 2/7, 10,978,457,896….
Negative numbers are less than zero on a number
line. Ex: -1/2, -1, -99 2/7, -10,978,457,896…
Zero is not positive or negative (Remember, it is
nothing!!!)
Integers on the Number line
For every positive number there is a
negative number.
 A number line is continuous in both
directions.


-1

Guided Practice

Write the number sentence represented by the word problem.
An elevator started at the first floor and went up 18 floors. It then came
down 11floors and went back up 16. At what floor was it stopped?
Ex:
went up 18 = +18
down 11 = -11
up 16
= +16
(+18) + (-11) + (+16)
At midnight, the temperature was 30F. By 6:00a.m., it had dropped 5F and
by noon, it had increased by 11F. What was the temperature at noon?
Ex:
Temperature was 30F = +30
Dropped 5F
= -5
Increased 11F
= +11
(+30) + (-5) + (+11)
Independent Practice
Write the integer for each situation.
1. A gain of 6 lbs
6. 6 ft below sea level
2. A deposit of $15
7. 15 s before blastoff
3. Score 10 points
8. A withdrawal of $14
4. 5 years ago
9. A debt of $12
5. 2 km below the surface
10. A gain of 9 yds
Conclusion
Students use integers to name situations.
