I recently purchased and tried Division Unplugged as a remedial resource for my grade five students. I found it to be thoughtfully constructed and that the songs were quite musically done. Each song not only teaches division facts, but reviews them by reminding the student of the multiplication tables. The choruses of each of the songs also incorporate skip counting, so even the slowest of students is able to make the connection between multiplication facts and division questions. Great job. I would recommend it to anyone.
