Children as young as 3 proudly announce what they want to be when they grow up. Firefighter, store clerk, teacher, and doctor are common choices because these are the jobs they see people doing. WHO USES THIS? expands their understanding of the work people do. Now children may imagine themselves as carpenters, jugglers, football players, bakers, gardeners, dog walkers, conductors, barbers, or artists.
Three photographs are presented for each tool to reinforce how implements are used by these professionals. The text reads, "Who uses this?" and on the facing page the tool is pictured in isolation against a color background. Turning the page answers the question, as two full-page photographs show a professional using the tool at work and a child using the tool to role-play. Children from various ethnic backgrounds are represented.
