Written in the form of rhyming questions, and accompanied by delightful illustrations that capture the word-play of the text, this book teaches the collective terms for groups of animals while imagining what these groups might be getting up to (e.g. “Does a pack of wolves load up bags for vacation? Does a cast of hawks get a standing ovation?”).  I learned a thing or two reading this book: I knew a group of crows was a murder and a group of tigers an ambush, but I had never heard of a crash of rhinos or a shiver of sharks or a parcel of penguins.  A glossary in the back provides the common-usage definitions for all the collective terms included in the book, in case young readers didn’t understand the illustrations or word play.  I just wish it would have had (if anyone knows) reasons for how these collective terms evolved (a prickle of porcupines seems obvious enough, but why a rumba of rattlesnakes?).  This could be an excellent discussion topic for students after reading.
