Make flash cards, have them read it out loud, you read it out loud to them, quiz
them, make homemade worksheets.
c. Have an area set aside with NO distractions. Some students can study with music in the backround, the TV on, or with a view of the outside world, but students with ADD can't handle that and still be productive. They already battle the distractions in their head about EVERYTHING else, outside distractions should be minimal, if not, nonexistant.
d. Take lots of breaks.
