I know many families who spend a LOT of money on boxed curriculum’s for there kids. Some are really good. But you don’t have to spend thousands of dollars to have a great home school curriculum you don’t need to spend much at all.
What i have bought Life of Fred,http://lifeoffredmath.com/ that will be used by all three kids. Kumon math workbookshttp://www.barnesandnoble.com/s/kumon-math-workbooks?store=ALLPRODUCTS&keyword=kumon+math+workbooks , I buy them at Barnes and Nobles and use my teacher discount card.
