Paula at Paula's Archives has a brand new page with a Latin curriculum comparison chart, gathered up from discussions at the Well-Trained Mind K-8 curriculum board. I don't frequent the boards, so I'm happy for this resource.
If you're a classical homeschooler and you're not familiar with Paula's Archives, you and your kids are missing a tremendous resource (not entirely secular, by the way). Check the previous link for an index which includes Story of the World resources; lists of literature to supplement history, living science books, movies to co-ordinate with your studies, easy chapter books, oodles of links, and much, much more. And I learned about the brand new Latin page since I'm signed up to receive e-mail alerts via Paula's Yahoo group, a very low-traffic, virtually one-way, group.
