A number game is played with a number cube and a number line. When it is your turn, you roll the number cube twice. The first roll tells you how many units to move to the left from the starting point. The second roll tells you how many units to move to the right from where you stopped after your first roll. If the starting point is (−4), what is your ending point if you roll 5 on the first roll and 3 on the second roll?

• −12

• −6

• −2

• 4

A number game is played with a number cube and a number line. When it is your turn, you roll the number cube twice. The first roll tells you how many units to move to the left from the starting point. The second roll tells you how many units to move to the right from where you stopped after your first roll. Which number sentence represents starting at (-2), rolling a 4 on the first roll, and rolling a 2 on the second roll?

• -2 + 4 + (-2) = 0

• -2 + 4 + (-2) = -8

• -2 + (-4) + 2 = -4

• -2 + (-4) + 2 = -8
