Daughter does literature first, it was her choice and she enjoys it. Then is math, because she can concentrate best then and that's why it come after literature. The rest are as she wants to do them through out the day.
My guys are older, ages 12 & 15, so I do not stand over them much any more or require that things be done in a certain order. I just require that they all get done: the order is up to them. My youngest usually chooses Bible or reading first. My oldest usually does history or math first.
Prayer. We start our school day with prayer and Bible, then calendar, science and then we alternate history, health, manners and character each day. That is with all of them together.
When we break off separately..it just depends. Usually Math.
