You'll certainly get your money's worth here. The story works on several levels. It's an adaptation of a familiar song; it's a math concept book (showing the numeral, the word, and a multiplication picture block); it's a "predictable book (Anthony stops every other page), it's a maze; it's an inter-active book (the reader get's to decide which of three verb and three noun combinations Anthony should do at each stop); and it's entertaining for the adult (identifying all the locations in Anthony's underground world).
This needs to be included in story kits and story times having to do with ants, of course, or math concepts, or picture books of familiar children's songs. If you're looking for a gift book consider this one.
