For a small child there is no division between playing and learning between the things he or she does just for fun and things that are educational. The child learns while living and any part of living that is enjoyable is also play.
Growing up if I hadn't had sports I don't know where I'd be. God only knows what street corners I'd have been standing on and God only knows what I'd have been doing but instead I played hockey and went to school and stayed out of trouble.
