Diane at Foreign Language Fun has shared these cute games to play with your little ones but I can see playing them with kids at any age (even in high school).
All of her bean bag games are designed to teach simple concepts like numbers, letters and body parts- words that all new foreign language speakers learn first. I think playing the counting game with middle school students would inspire a lot of laughter.
Having taught high school myself, I know that teenagers would enjoy this break from drill and practice as well and would likely remember the content longer than if you used flashcards or repeated recitations.
