Max is looking for words that rhyme. His dragon is in his wagon - or was, for now its tail has left a trail, which Max follows. He finds an umbrella on the ground-- "Found, ground," he says, while his older brothers mock him for believing in dragons and sitting under an umbrella when it isn't even raining. But Max believes in possibilities--and when he can show his brothers not only a dragon in the stormy clouds but also a dinosaur, they begin to come round. When Max demonstrates the power of his rhyming words to tame the dinosaur and the dragon and make the rain come, he wins them over completely. With amusing wordplay and beguiling illustrations, Kate Banks and Boris Kulikov celebrate language and imagination in a collaboration that is bound to be oodles of fun for everyone. This title has Common Core connections.
