Five friends parked in an underground garage, and they cannotremember where they left their car! So they split up andsearched the garage. Read the descriptions of their tripsbetween levels. Use integers to show on which level eachperson started and the change in their locations. Then, namethe level where they exited the elevator and label their namesat that level on the diagram.
Challenge Going Up or Down?
1. Tammy got on the elevator on theground level. Then she rode downseven levels and got off the elevator.

The temperature was three degrees above zero when Janie went to bed. When she woke up the temperature had dropped eightdegrees. What was the temperature when Janie woke up? Thenumber line can help you solve this problem: 3 � 8 � ?
Use the problem above and the number line to answer thefollowing.
1. Starting at 0, in which direction do you move first?
to the right2. How many places do you move in that direction?
3 places3. Which direction do you move to subtract 8?
to the left4. Where will you be on the number line after subtracting 8?
at �55. What was the temperature when Janie woke up?
5 degrees below zero
Use a number line to answer the following: (�5) � 8 � ?
6. From 0, which direction do you move first on the number line?
to the left7. How far do you move in that direction?
5 places8. Which direction will you move next?
