Interval Couch Bounce: A Piano Game

I ran across some posts about using active games to teach kids with ADHD piano, but no actual games I could use in our specific situation.  But here is the one I came up with today.  It went over really well with DD, who tried to get her brother into the act as well!

Interval Couch Bounce

What you need:
2 soft chairs--a couch and an easy chair or two parts of a sectional would work fine, you could also use two piles of soft cushions
parents who are ok with bouncing in the piano room
a piano

How to play:
Teacher says, "I am going to play an interval for you.  If it is a second, you bounce on the couch.  If it is a third, you bounce on the chair."
Student gets point if they are correct.  Teacher gets point if student is wrong.  (In our case the score was highly irrelevant, but just in case it matters to your student, that's how its scored.)
