When Frank, a boy, meets Lucky, a dog, “Both of them were just pups. They had a lot to learn.” That’s exactly what school is for. For Frank and Lucky, the world is their classroom. With Lucky’s help, Frank learns Botany pulling burrs from Lucky’s coat, and Chemistry and the try-again aspects of experimentation attempting to remove the skunk smell when Lucky gets sprayed. (They study Astronomy under a night sky when Lucky is banished outside.) Lucky excels at listening during Reading, while Math is everywhere (How many biscuits? How much hair is it possible to shed?), even fractions (“how much of the bed is Lucky’s, and how much is Frank’s?”) Art, History, Geography—lessons aren’t lessons at all when Frank and Lucky are together. The detailed illustrations, full of speech-bubble dialogue and additional moments of humor, are a pleasure to pour over and a seamless part of the storytelling in this warm, clever offering. (Ages 4–8)
