The latest addition to the Small World series, which shows children around the world engaged in similar activities, focuses on the very human act of smiling. Using full-color photographs, Swain supplies a rhythmic cascade of statements and queries: “Do you smile when you put on a hat? Do you smile for the camera, just like that?” Every page contains a photograph with one to two lines that are simple enough for beginning readers to attempt. The scope of photographs allows children to stretch their imaginations: all convey the information that people are more alike than different. An index provides further information on the locations and settings of the photographs. (Picture book. 3-7)
