How about simplification of fractions! Not bad for a kid with Down's syndrome. Hannah spends less than 15 minutes at a time on her VIP maths. No drama, no fear! Just smooth uninterrupted learning. When concepts are not completely grasped we repeat the book until it is grasped. She works for between 3-5 days a week on VIP maths. It's portable so she can take work on long trips or on holiday. The pages are colourful so it doesn't really seem like work.
