I have used this on three boys. I use it has a supplement to First Language Lessons, All About Spelling, and Christian Liberty Press Phonics A, B, & C. I think they get more out of it when I use the exercises in the Teacher's Guide, but I do not always get to them, and I do not do all of the TG exercises-- LOL ! Sometimes they finish three lessons and THEN we do a "crash course" of some the exercises from the Teacher's Guide as a sort of review, quiz, or "test". I only do this delay, because they finish faster than I have the time to do the lessons and I don't want them waiting on me. I have not used the second edition.
