Integer With Counter

In class we modeled integer addition problems with counters.

Yellow is Positive and Red is Negative

• 4 + (-3) = 1

• -4 + (-3) = -7

• -4 + 3 = -1

• 4 + 3 = 7

How many Zero Pairs are in the model?

• 6

• 4

• -2

• 2

What is the sum?

• -2

• -4

• 6

• 2

Which equation represents the 2-color counters shown in the image?
Yellow is Positive and Red is Negative

• 4 + 1 = 5

• 4 + (-1) = 5

• 4 + (-1) = 3

• -4 + 1 = -3

• -7 + 4 = -3
• 7 + (-4) = 3
• 7 - 4 = 11
• 7 + (-4) = -11

Use the number line to find the sum.
-8 + 3 =

• -5

• 5

• -11

• 11

Find the sum of the integer model shown.

• -5 + 3 = -2

• 5 + (-3) = 2

• 5 + 3 = 8

• -5 + (-3) = -8

Which number is an example of an integer?

• 1/8

• .39

• -7

• 8.3

What number does this represent?

• 6

• -6

• 2

• -2

Use the counters to find the sum of the integers. 

• -5

• -7

• 5

• 7
