Download the Little Reader two week trial. It will help her learn 3,000 words in the course of a year, more than any other program out there, including tons of CVC words (cat, rat, sat, mat, etc) to help her solidify phonetic rules. This is hands down my favorite and it's the most versatile. We still use this program almost 2 years later, now to teach foreign languages since my kids have mastered the program in english. They still love to watch the stories and fables tho.
I also like LeapFrog's Letter Factory as a quick and easy way to learn letter sounds, they sell some packs on amazon that include the flashcards or you can download them here.
