Casey Runner

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

Knowing that ++ or −− make a positive, and +− or −+ make a negative (read How to Add and Subtract Positive and Negative Numbers) see if you can help Casey reach the finish line.

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!
