I purchased this book for DD6, I bought it mostly for a fun tool to introduce concepts. The funny thing is that she has corrected me on some of the anwsers. (OK, so I wasn't that great at math) I've given it over to my DH who IS good at math. DD loves the story line so she's very interested in it, and picks up the concepts and figuring out the problems with ease. I was worried that she might not be interested because it was about a boy, but there's enough girly things included that it does the job. It gets them ready for algebra and beyond and what a great ideal math made fun!
