You do not have to drop what you bought or built. Add the resources you already use. A resource can belong to the whole family or to one child, so a mixed shelf is fine: one math program, living books for reading, a co-op science class.
Plans and lessons draw on that library when a resource fits the day. Grades run from Pre-K through 12th. Add each child you teach.
Set one teaching approach for the family. Lessons and Ask Omega follow it. The approaches are Classical, Montessori, Charlotte Mason, Unschooling, Traditional, Eclectic, Unit Studies, and Waldorf. Choose Eclectic when you mix methods by child or by subject.
