Temperature Drop
6. In one hour, the temperature dropped 2
degrees. In the next hour, the temperature
dropped an additional 3 degrees.
a. What integer represents the total
temperature change over these two
hours?
b. Write an addition expression that
describes this situation.
c. Suppose the temperature rose 4
degrees in the third hour and dropped 1
degree in the fourth hour. Write an
addition expression to represent the
temperature change over all four hours.
d. What integer represents that change?
e. Mode the temperature change on a
vertical number line.
True or False
7. Let n = any number . Then -n is always a
negative number. Explain your claim. If true
provide evidence, if false provide a counter
claim.
Gophers
11. A gopher begins at 7 inches below the surface
of a garden and digs another 9 inches. Find the
integer that represents the gopher’s position in
relation to the surface of the garden.
Construct Viable Argument
8. Explain how you know the sum of 5, 4, and -5 is
positive without actually adding. Make sure to
use appropriate math vocabulary in your
explanation as well as detailing your reasoning.
Creating a problem
9. Create a real-world problem that can be solved
using the number line below.
Computation
10. Find the sum. Model the equations using either
counters or a number line.
a) 10 + (-3) + 3
b) -15 + 8 + (-9)
c) 8 + (-11) + (-19) + 11
d) -7 + (-1) + 7
e) -6 + (-2) + 14
f) 13 + 20 + (-17) + (-13)

account and wrote a check for $38. What was is
your account balance?
Scores
13. At the end of hte first round of a game show,
Julian had a score of 40 points and Marty had a
score of -50 points. Find the difference
between the two scores. Write the expression
you would use to solve this problem.
Multiple Representations
14. An underwater video camera is 7 feet below the
surface. It will be lowered an additional “f” feet.
a. Write an equation to show how many
total feet below the surface the camera
will be after it is lowered.
b. Make a table to show the depth of the
camera if it is lowered 5, 8, 10, or 12
feet.
True or False
15. A subtraction expression with a positive integer
and a negative integer can have a difference of
zero. Explain your claim. If true provide
evidence, if false provide a counter claim.
Computation
16. Find the difference. Model the equations using
either counters or a number line.
a) 6 - 7
b) -20 - (-30)
c) 1 - (-18)
d) 5 - (-10)
e) 4 - 8
f) 15 - (-14)
