In Police Cars, early readers will learn about the different parts of a police car and how they help police officers do their jobs. Vibrant, full-color photos and carefully leveled text will engage emergent readers as they discover the unique features of these machines. A labeled diagram helps readers identify the parts of a police car, while a picture glossary reinforces new vocabulary. Children can learn more about police cars online using our safe search engine that provides relevant, age-appropriate websites. Police Cars also features reading tips for teachers and parents, a table of contents, and index. Police Cars is part of Jump!'s Machines at Work series.
