Also check out your local library for resources. A series of books by E.D. Hirsch, "What Your Nth Grader Needs to Know" will help you formulate a plan. We don't HS(yet), but a friend who does recommended that series when we weren't sure if GS would be staying with us permanently. It helps make sure there are no gaps if the child is going to different schools. We use it to round out our afterschooling. I use it for ideas on reading material for GS9. It gives the typical math sequence, and we use Singapore Challenge Word Problems for math supplements.
