I feel like we'll probably need to do pre-algebra given our late switch to Horizons. We left MUS because of the mastery (vs. spiral) approach. I feel like we got behind. Maybe mastery is better with algebra, but I'm not sure I want to return to MUS. Instead, I've read that Lial's is self-explanatory and Forerster's is also "gentle". I like the idea of having dvd's available like Chalkdust offers. Life of Fred seems very popular, but I'm not sure how it compares to these other curricula. What pre-algebra do you all like the best?

I have a 6th grader using Horizons Math (grade 6) for the first time. (We used MUS for grades 1-5). Since this is the last book in the Horizons series, will someone share with me what you went to after 6th grade Horizons?
