Hmmm interesting concept...thinking.
You could teach ordinals (first point second point etc)
Tenses...What is bob going to do? He is going to throw the ball.
What is bob doing? Throwing the ball
What did bob do? Threw the ball. (You could just ask these questions as the kids play...baseball, basketball...anything.)
I'll have to think about this more. It is an interesting idea though.
