PreS-Gr 1 The essence of the traditional children's song is aptly captured in this picture book adaptation that retains the exuberance and rollicking action of the song. Kovalski builds a humorous original story around the traditional verse. A long wait at the bus stop precipitates a suggestion from a grandmother that she and her two grandchildren pass the time by singing ``The Wheels on the Bus.'' When grandma and the girls get carried away with their song, missing their bus, ever-resourceful grandma hails a cab. Kovalski expertly conveys the spirit with which people sing this song; indeed, this grandmother and these children become so involved that bus scenes are vividly recreated in their minds and on the pages of this book. The action of the song is followed through in detail, flowing from page to page with a cast of assorted characters depicted in watercolor with pencil illustrations. Musical notation accompanies the first verse. Good fun for young children and parents. Susan Nemeth McCarthy, Arlington County Public Library, Va.
