My son is very mathy and he loved Life of Fred - I ordered the first 4 books as a set. He read them all in a week but he goes back and rereads them. They don't just have math in them - they are told as a story and there are other tidbits of info in there relating to other subjects that he learned as well. I need to order the next 4.
