For my 10th grade DD we used Story of the World 4th through 7th grade followed by 1 year of American History using the Artner's guide (available through Memoria Press). Now for high school we are using the Great Books program 4 year cycle available through Angelicum Academy.
At the same time I had my now 8th grade DD use SOTW for 2nd through 5th grade, 1 year American History, 1 year World History (Christ the King, Lord Of History)Now 1 year of Modern History, then next year she will begin Angelicum program.
I was just talking with my little sister about it tonight and talked her out of starting her 1st grader with SOTW this year. It is so amazingly wonderful that I think it is a little of a waste to start it too young. We did all the projects and so many corresponding literature suggestions and the tests as wel. They got so much out of it! lI have tried to do my kids as sets. I am now on another set of kids and again waited for 2nd and 4 th grade, b/c I think it is ideal to start in 3rd grade.
