Do okey cokey with big movements
Try brushing your teeth with your non-dominant hand
Throw a ball (or crumpled up newspaper) to someone or against the wall, see you many times you can do it without dropping it, maybe get brave a clap between each throw. Or use hand to catch and throw

If you have a racket and ball, or crumpled up newspaper. Count how many times you can bat it up and down in the air, without dropping it.
Balance a book on your head and walk around the garden, time how long you can do it before it drops. Try and beat this time.
