Answer Key
Part I - Directions: Use the number sentence above each table to answer the questions
within the cells.
Original Sentence: -8 + -3 = -11
1
Use the commutative property of addition to write an addition number sentence that is equivalent to the
original number sentence.
-3 + (-8) = -11
2
Write the subtraction sentences that are equivalent to the original sentence and the sentence created in
#1.
-8 – 3 = -11 and -3 – 8 = -11
3
Use one of the equivalent subtraction sentences in #2 to explain why the commutative property of
subtraction does NOT exist.
If I commute the numbers in the sentence -8 – 3 = -11, then the equation
becomes 3 – (-8) = 11 which is not the same as -8 – 3 = -11.
Original Sentence: -7 – (-5) = -2
4
Write the addition sentence that is equivalent to the original sentence.
-7 + 5 = -2
5
Use the commutative property of addition to write an addition number sentence that is equivalent to the
sentence in #4.
5 + -7 = -2
6
Use the original subtraction sentence to explain why the commutative property of subtraction does NOT
exist.
If I commute the numbers in the original number sentence, then the
equation becomes -5 – (-7) = 2 which is not the same as -7 – (-5)= -2.

7
Write the addition number sentences that are equivalent
to -11 – 5 = -16.
-11 + (-5) = -16 and -5 + -11 = -16
8
Write the subtraction number sentence that are
equivalent to -8 + (-7) = -15.
-8 -7 = -15 and -7 -8 = -15
9
Write the subtraction number sentences that are
equivalent to -4 + (-1) = -5.
-4 – 1 = -5 and -1- 4 = -5
