PreS-Gr 1–Children explore five different buses in this brightly illustrated interactive book. Spreads reveal one of the buses with a sturdy full-page flap to lift to discover new vocabulary. Those who can read will find a clearly labeled diagram and learn about different parts of the bus. Questions throughout ask readers if they know what each bus does, creating opportunities for group or individual discussions. There are expected vehicles like a mass transit bus and a double-decker bus, but also unexpected ones like a monster truck school bus and a road trolley. The illustrations show diversity in the skin colors and genders of the bus drivers and in the different places in the world where these vehicles are found. This is the latest installment in the “Finn’s Fun Trucks” series and can stand alone, although children may ask for more entries after exploring this one. VERDICT Sure to be popular with transportation-loving children, and the flap feature is sure to keep even the youngest child engaged.
