There is no shortage of picture books featuring geometric shapes, but surely this is one of the brightest. Grover (Amazing and Incredible Counting Stories, 1995, etc.) mimics children's art in his use of simple shapes and naive perspective, but composition and the balance of the intense colors are sophisticated. The book begins with circles--tires--on cars, then on trucks, and then as part of an interlacing jumble of ""tires and cars and trucks and roads."" Squares are shown first as windows, then buildings are added, with roads between. Circles and squares are combined as boxes are loaded on trucks and smokestacks are added to buildings; boats appear, and finally all the elements seen on earlier pages come together in a busy panorama. An eye-catching elementary introduction to the notion, also found in Dayle Ann Dodds's The Shape of Things (1994, not reviewed), that these basic shapes can be found everywhere.
