Lessons and Tut activity

I am thinking about the lesson planning that is needed for the HPE classes and what I am going to be doing with the group for tomorrows tutorial, for the opening activities. As the weather can be changable this time of year I will need to accomodate that into my ideas of what we can do, I am hoping it is fine so we can use the courts outside and play our game/activity there otherwise I am considering a ball catching activity working in a square in the gym. The outside activity is a "Traffic Light" Activity where each colour has a different meaning and involves a different form of locomotion. 
Red is as always "STOP".
Orange can be any form of locomotion from skipping to crawling.
Green is traditionally running or a faster paced movement.

Anyone that moves on Red must go back to the start and try again.
