This unusual approach to explaining punctuation uses pop-up scenes, flaps, tabs and other features of paper engineering to bring some pizzazz to an often dull subject. Each spread features a different group of amusing animals or cheerful children to explain several punctuation marks and their functions, usually by lifting a flap to read the explanation underneath. Pulling tabs marked with arrows can slide commas into place, create contractions or combine two sentences into one. A final pop-up page full of pigs and wolves shows a long, complex sentence that includes every sort of punctuation all at once. The fragile nature of this format limits the use of the volume, but elementary school teachers may find this a useful teaching tool. Young writers and collectors of pop-up volumes will also be intrigued. (Nonfiction pop-up. 6-10)
