What integer represents "a loss of 15 yards"?
Vocabulary: An integer is
any whole number, including
positive numbers,
negative numbers, and
zero. A loss or decrease is represented by
a negative number.
✓Correct! A loss is negative, so "a loss of 15 yards" is represented
by the integer -15.
✗Not quite. A "loss" means a decrease, which is a negative number.
The answer is B: -15.
Warm-Up 2
True or False: The opposite of -7 is 7.
Vocabulary: The
opposite of a number is the same distance
from 0 on the number line, but on the other side. For example, the
opposite of 3 is -3.
✓Correct! -7 and 7 are on opposite sides of 0, each 7 units away.
They are opposites.
✗Actually, the opposite of -7 is 7. Both are 7
units from 0 but on opposite sides of the number line.

Practice 1
Write the opposite of each integer.
Remember: The opposite of
a positive number is
negative, and the opposite of a negative
number is positive. The opposite of zero is
zero.
a. Opposite of 12 =
b. Opposite of -5 =
c. Opposite of 0 =
Sentence frame: "The opposite of ___ is ___ because they are the
same distance from 0 but on ___ sides."
✓All correct! The opposite of 12 is -12, the opposite of -5 is 5,
and the opposite of 0 is 0.
✗Some answers need another look. Remember: flip the sign to find the
opposite. The opposite of 0 is still 0.
Practice 2
Which point on the number line shows -3?
Hint:Negative numbers are to the
left of 0 on a horizontal number line. Count 3 tick
marks to the left of 0.
✓Correct! Point B is at -3, which is 3 units to the left of 0 on the
number line.
✗Not quite. Count 3 tick marks to the left of 0. That's -3, which is
Point B.
Practice 3
Sort each value into the correct category:
Positive, Negative, or
Zero.
Remember:Positive integers are greater than 0.
Negative integers are less than 0.
Zero is neither positive nor negative.
+9
-4
0
-12
3
-1
Positive
Negative
Zero
✓All correct! Positive: +9 and 3. Negative: -4, -12, and -1. Zero:
0.
✗Some items are in the wrong group. Positive numbers are above 0,
negative are below 0, and zero is its own category. Try again!
Practice 4
What is the opposite of the opposite of 8?
Think step by step: First, find the
opposite of 8. Then, find the opposite of
that answer.
Explain your reasoning:
Sentence frame: "The opposite of 8 is ___. The opposite of ___ is
___. So the opposite of the opposite of 8 is ___."
✓Correct! The opposite of 8 is -8. The opposite of -8 is 8. The
opposite of the opposite always returns to the original
number.
✗Think again: opposite of 8 = -8, then opposite of -8 = 8. The
answer is C: 8.
Practice 5
True or False:
Zero is neither positive nor negative.
Think about it:Zero sits right in the middle of the number
line. It is the boundary between positive and negative numbers. Does
it belong to either group?
Explain your reasoning:
Sentence frame: "Zero is ___ because it is not greater than 0 and
not less than 0. It is the ___ between positive and negative
numbers."
✓Correct! Zero is neither positive nor negative. It is the boundary
point on the number line between positive and negative
integers.
✗Actually, this is true. Zero is neither positive
nor negative. It sits at the center of the number line.

The temperature dropped from 5°F to
-5°F. Use the number line below to mark both
temperatures, then explain the opposite relationship between 5 and -5.
Think about it: 5 and -5 are
opposites. They are the same distance from
zero, but on opposite sides. A temperature
drop from 5°F to -5°F means the temperature crossed 0.
Explain the opposite relationship between 5°F and -5°F:
How far apart are these temperatures? How does each relate to 0?
Sentence frame: "5 and -5 are opposites because they are both ___
units from 0, but on ___ sides. The temperature dropped ___ degrees
total."
