As with his recent booksTrains, Trucks, Airplanes and BoatsMachines at Work is characterized by bold, black outlines and vivid colors. Barton takes youngsters through an entire day at a construction site. The workers, a multiracial group of men and women, arrive and begin their day. Unlike other books on big machines for this age group, Barton's is not a catalogue of heavy equipment. Each vibrant spread shows people and machines actively working. The short, punchy narrative reinforces the dynamics of the illustrations. Kids are fascinated by dump trucks, bulldozers, cranes, cement trucks, etc. This will prove a popular read-aloud for preschoolers and satisfying read-alone for beginners. Ages 3-7.
