All the "Key To" books are excellent for teaching these concepts. I am using them for review and drill over the summer months. Get great marks on the state tests in Nov. if the kids stay on top of these subjects! (especially fractions and decimals)
My kids literally teach themselves. I check it every once in a while to make sure they understand and they rarely miss any. Not only that, they fully understand what they are learning. I am amazed. I plan on using the algebra and geometry series next, which I feel they have been fully prepared for.
