I second the Well-Trained Mind book and Singapore Math. There is a forum for homeschoolers who follow classical curriculum:

You can get good advice from parents who have been there and done that smile

Also, check out the Veritas Press website: http://www.veritaspress.com/
They provide Christian classical curriculum. Even if you don't want to follow the religious parts (Biblical based science or religion), you can get good information on curriculum for other subjects (literature, grammar, etc).

We don't homeschool, but we have used Bauer's book and Veritas Press website to have a better idea on supplementing our kids. We are also using Singapore Math at home.
