Internet programs or websites for help with First grade reading programs/comprehension?

ClickSmart by HeadSprout helped my little sister learn to read. It has an online program, books that come in the mail, and a progress sheet for your youngster to keep track of all the levels (there are 80) he/she completes. It also has a comprehensive parent's section so you can monitor your childs grades. My llittle sister loved all the music, animations, characters, and the fact that she could work at her own pace.
