Thank you for your reply! I do have other children. Twins who are starting 8th grade. But these two are in school and I will be just supplementing.

I'm having a very difficult time decidiing how to start the 4 year cycle as I am starting with one in 4th grade and one in 7th grade. I have read "The Well Trained Mind - A Guide to Classical Education at Home". Can I just start both with acients and just keep going? Can I follow History of the World and then complement for the one in 7th grade, and add The Great Books when he starts 9th grade? I would love some help with this. Thank you.
