Well, I may do this...
Have my younger ones do FIAR(we are already using and love) say K-3...we will read other picture books for history and science.
My high schooler is independent. I may do HOD CTC and up with any of my 4th-8th graders. I may have the younger ones to listen to some of the reading. It would be sort of a rotation schedule.
I wouldn't mind using SOTW, but I can't schedule music, art,...and I don;t do science or bible very good if it is not scheduled.
I am not a good make my own schedule person.
