1 Add Subtract Positive Negative integers
by Matching

2 = 0 N + P = 0

3 -6 + -8 = -14 8 + -5 = 3 N N P N P + N = 0 So we mark them out.
We are then left with 3 Positive Count the total number of Ns which is 14

4 3 + -8 = -5 7 + -2 = 5 P N P N P + N = 0 So we mark P + N = 0 them out
= -5 = 5 P + N = 0 So we mark them out P N P + N = 0 So we mark them out. P N We are then left with 5 negatives We are then left with 5 Positive

5 ______________________
Group Practice ______________________ Name Do together as class. Write the N for negative numbers and P for positive number. Mark out pairs and what is left is the answer. = ____ = ____ = ____ = ____

6 ______________________
Group Practice ______________________ Name Do together as class. Write the N for negative numbers and P for positive number. Mark out pairs and what is left is the answer. = ____ -2 = ____ = ____ = ____ N P

7 ______________________
Group Practice ______________________ Name Do together as class. Write the N for negative numbers and P for positive number. Mark out pairs and what is left is the answer. = ____ -2 = ____ = ____ = ____ N P P N 3

8 ______________________
Group Practice ______________________ Name Do together as class. Write the N for negative numbers and P for positive number. Mark out pairs of positive and negative and what is left is the answer. = ____ -2 = ____ = ____ = ____ N P P N N N 3 -16

9 ______________________
Group Practice ______________________ Name Do together as class. Write the N for negative numbers and P for positive number. Mark out pairs of positive and negative and what is left is the answer. = ____ -2 = ____ = ____ = ____ N P P N N P p N N 3 -16 -5

10 -6 + -8 = ______ -14 Rules for Adding Integers
Alike: Add Keep the sign Different: Subtract take the large number sign = ______ -14 N N Add them up because there are no pairs of positive and negative to mark out.

11 6 + -8 = ______ -2 P N Rules for Adding Integers
Alike: Add Keep the sign Different: Subtract take the large number sign Subtract because you take away the pairs. What is left is the answer.

12 Matching Practice Name ______________________
