This one is Grade 2 "Creature Math." Each page has at least one problem with a cute little creature in it. This is a matching game where you wrap the string from each problem on one side of the page to the answer on the other.
Once you are done, you turn the booklet over, and if you got them all correct, the string pattern will match the pattern on the back.
It is great for a quiet riding-in-the-car or waiting-in-the-doctor's-office activity. There are other books and other grade levels available. Apparently these are out of print now, which makes me very sad, but you can still find them on sites like Amazon.
Also, if you are looking for fun Math games, check out Big Brainz.com. There is a free download for Timez Attack, a video game teaching multiplication tables. I have found it to be an oasis in the desert of math-teaching-tools-that-don't-appeal-to-boys!
Have a happy math class!
