Hi,
I have two daughters - one 10 year old with ADHD, math issues, and dysgraphia. The other (9 years old) has ADD, anxiety/ocd, and dyslexia. We have been using the Grammar Ace purchased through Sonlight (FYI-it does not have religious references). It is a very simple grammar program that utilizes Schoolhouse Rock to help teach the concepts. The activities are simple, but have worked well for both of them, and they LOVE grammar. The concepts are sticking, and they even correct me sometimes. I have enjoyed it as well. This is a good BASIC program. Don't expect sentence diagramming, but it does help and is a lot more fun than the torturous programs we tried before. Some of the activities are a little young for the 10 year old, but I just adjust them, and it's fine.
