Math SOL 6.6 - 2016

1) Larry used the model given to solve the following model.

• -10

• -4

• 4

• 10

2) Look at the model.

• 5 - 3 = 2

• 5 - (-3) = 8

• -5 - 3 = -8

• -5 - (-3) = -2

5) Use the number line to complete the sentence.

The value of y + z is -

• negative, because y is closer to 0 than z.

• positive, because z is farther from 0 than y.

• negative, because both y and z are negative.

• positive, because both y and z are negative.

5) Use the number line to complete the mathematical sentence.

• positive, because z is farther from zero.

• positive, because y is closer to zero.

• negative, because y and z are both positive.

• negative, because y is negative and z is positive.

6) Look at the key and model. Which correctly describes the model shown?

• -3 - 2 = -5

• -3 + (-2) = -5

• -9 - 4 = -5

• -13 - 8 = -5

7) Which number sentence is illustrated by the diagram shown?

• 3 + (-5) = -2

• -2 + 3 = 1

• -2 + 5 = 3

• 5 - 2 = 3

• -2 + (-3) = -5

8) Which number sentence is represented by this model?

• -3 ^. 6 = -18

• -3 ^. 6 = 18

• -3 ^. (-6) = -18

• 3 ^. (-6) = -18

9) Which expression is represented by the model?

• -7 + 7

• -7 + 3

• -7 + 0

• -7 + 10

11) Look at the model. Which number sentence represents the model?

• 16 ÷ (-4) = 4

• -4 ^. (-4) = -16

• 16 ÷ (-4) = -4

• -4 ^. 4 = -16

12) Look at the model. Which number sentence represents the model?

• -5 - 3 = -8

• 5 - (-3) = 8

• -5 - (-3) = -2

• 5 - 3 = 2
