From Serfozo (Joe Joe, 1993, etc.), an introduction to the square, circle, triangle, rectangle, oval, and diamond. Each one is identified and defined in simple catchy rhymes—bouncy enough to be read aloud—and copiously illustrated with accompanying shapes of all sizes and textures. Cut-paper collages feature bright, anthropomorphized shapes (with very expressive faces) against landscapes suitable for the featured shape. The book is conceived as an entertaining lesson, and concludes with a carefully designed review that makes sense of shapes in an easy and imaginative way. (Picture book. 2-4)
