I just purchased several programs from
Bloomingkids.com. Their software is designed for kids with learning disabilities, autism, PDD and ADD. The software keeps track of progress on the lessons and will even generate charts. They currently have 37 programs. What I really like is the price. The software programs run between $14 and $16. They are also available for Windows or Mac. The Windows programs are available by download and the Mac software currently needs to be ordered.
