I don't have an ADHD child, so I can't speak about experience with that. I noticed that a couple people mentioned martial arts as a possible option and thought I'd share about that option. Our kids take Tae Kwon Do and there are several kids in their classes who are on the autism spectrum (especially Asperger's, but also other types). I have been hearing that TKD (and I'd imagine any martial art) is good for kids with autism. It seems to me that martial arts would be helpful for kids with ADHD for similar reasons: it's active, involves focus, develops self-control and discipline, provides a good physical workout, encourages body-mind connection and awareness. Same thing with dance. In any case (and in my perhaps uniformed opinion), I would think that she would benefit more from an activity where she has an instructor and other students working with her. Good luck and have fun with whatever you/she choose!
