Make your own iPad stylus... CHEAP!
I have found these to be extremely useful with students who have multiple disabilities and very limited fine motor control. It can be difficult to help these students stick out/isolate one finger to interact with (swipe, touch) the iPad, but it can be a lot easier to help them somehow hold a stylus (sometimes, the longer the stylus the better). Plus, more of the iPad screen can be seen when your hand isn't covering it!?
NOTE: Use galvanized metal wire to avoid rust.
