Casey Runner

Meet "Casey Runner". Casey can run backwards or forwards, and can also face right (positive) or left (negative direction).

See if you can help Casey reach the finish line using this guide:

• ++ or −− make a positive
• +− or −+ make a negative

 Learn more at How to Add and Subtract Positive and Negative Numbers.

Try This In Real Life!

Mark a number line on the ground (using tape or chalk) just like above.

Then throw a die to decide distance, like this (you can put stickers on the die to make it easier):

+1	+2	+3	−1	−2	−3

See who wins!
