There are lots of people in our lives that help us each and every day. But, we don't see everything they do behind the scenes! What do firefighters do when they are not putting out fires and saving lives? How do bus drivers make sure the bus is safe to drive? Readers discover the answers to these questions--and others they may have--in this set! With full-color photographs depicting real people performing these jobs that complement the accessible text, these books are a great way to start talking about helping careers with young elementary readers.
