In Cranes, emergent readers will learn about the parts and functions of a mobile crane. Vibrant, full-color photos and carefully leveled text will engage early readers as they discover how a crane lifts and moves heavy materials to help do big jobs. A labeled diagram helps readers identify different parts of a crane, while a picture glossary reinforces new vocabulary. Children can learn more about cranes online using our safe search engine that provides relevant, age-appropriate websites. Cranes also features reading tips for teachers and parents, a table of contents, and an index. Cranes is part of Jump!'s Construction Zone series.
