Math Curriculum for Asperger's

My daughter has struggled with basic math for several years.  She can memorize facts, but I could tell nothing was clicking for her.  This year we found Math-U-See and now math is no longer a dreaded subject.  Math-U-See has not only made math fun and easy to learn, but it is beginning to click and be understood by my daughter who has Asperger's / High Functioning Autism.
