Move over, worksheets and pencils! The team behind The Grapes of Math once again proves that posing number problems through verse and vivid pictures is a powerful path to math learning. With titles like "Raining Cats and Frogs" and "Amazing Grain," the poems span the seasons, encouraging readers to look for patterns and symmetry in the playful illustrations. Each poem poses a "how many" question about the accompanying picture of seasonal items, from acorns and hatching chicks to dandelions and icicles. Several creatively convey facts about their timely topics, as in "Not-So-Dandy Lions": "These lions are a stubborn breed— / There's never just a single weed./ The trouble starts when they get loose,/ They catch a breeze and reproduce!" the simple verse then hints at effective strategies to make counting faster and easier. With 10 dandelions pictured on the opposing page, Tang poses the question "How many plants are still in bloom?" then suggests: "Count by fives the plants you see,/ Then subtract the seedy three!" Briggs sprinkles his computer-generated artwork with fun-loving graphics throughout. Summer-themed poems show a pigeon wearing swim goggles diving into a bird bath and a lemonade-drinking butterfly. Any time of year is a good time to delve into these pictorial puzzles. Ages 7-10. (Mar.)
