We'd very much like to change curriculum in at least two subjects (SS and Science), but are at a loss as to what's good, what works, and what falls woefully short of the mark. Our oldest will end this school year about 1/3 - 1/2 of the way through 5th grade and our middle son will end about 1/2 through 2nd grade. I've looked at "The Story of the World' at the suggestion of a friend, but Amazon.com reviews have me doubtful of it. I want something accurate, engaging, and well-rounded. I've also looked at American Education Publishing books, like "The Complete Book" series, but the History book got mixed - bad reviews on Amazon.

What have you used and liked?
