SarahCPA, THANK YOU for the link. I am torn about the MTH books only b/c my son, almost 9, loves reading them. I would love to find an alternative and these might just be it. I know just b/c he loves reading them is NOT a reason to keep them, but he is very strong-willed and I am really trying to pick my battles. There is much more to it, but anyway he is a voracious reader and likes the adventure … these may work. His birthday is coming in a couple of months. Our parents are more than glad to give our children books, so I am going to check these our further.
The research guides are good, but interestingly my son doesn’t care much for them!
