Math story problems aren’t always boring exercises about dividing up a bowl of apples or trains traveling between cities. Sometimes story problems can be rhyming, funny, and delightfully illustrated, as evidenced by this collaboration between Lewis (A World of Wonders, p. 48, etc.) and Remkiewicz, illustrator of the popular Horrible Harry and Froggy series. The 18 math puzzles are full of amusing names and situations, such as calculating the time for a quick trip to Kalamazoo or the weight of a poodle named Poo-poo-pee-doo. Three additional selections include a novel way to multiply by nine as well as a rebus-like round of letters between a dog and a cat (regarding a K-9 T). The text is printed on blue-lined notebook paper with the answers to the puzzles cleverly printed below each problem in reverse (adding a mini-science lesson when the answers are held up to a mirror to be read). Remkiewicz provides cheery illustrations in watercolor and colored pencil, with smiling children and comical animals in double-page spreads that will work well with a group. Most of the puzzles are at the third- or fourth-grade level, but many could be solved by younger children with an adult’s help. This is also an excellent choice for younger gifted children, who will enjoy the challenge of math problems with a humorous twist. (Nonfiction. 7-10)
