I found this great rubric on a blog called Phys Ed Review. Great blog with lots of assessment resources, as well as some really cool PE Geek resources. And the guy is a huge Star Wars fan, so he must be awesome!
Physical Education Games - Speedway! I did this with my classes today. I really like this one! I added an item in the middle for the kids to collect after each lap. The teams counted the items at the end. I also played speed racer song from the movie during the game.
