Hi Falon! I also have ADHD but I think it has helped me with learning music especially. For students with ADHD, ask a lot of questions to keep them engaged. I like to do exercises on musictheory.net with them because it is something that has helped me a lot!
I would curate an exercise for them based on their needs and their level. I would start off by doing the exercises with them whether it's note reading or pitch detection. It's a very engaging and fun way of learning core music. It's kind of like playing a game because you can turn on "challenge" mode and see how many answers you can get correctly in under a minute or something like that!
Hope this helps!
