In Tractors, early readers will discover the different jobs tractors perform on a farm. Vibrant, full-color photos and carefully leveled text will engage emergent readers as they learn about the tools tractors use for different jobs. A labeled diagram helps readers identify different parts of a tractor, while a picture glossary reinforces new vocabulary. Children can learn more about tractors online using our safe search engine that provides relevant, age-appropriate websites. Tractors also features reading tips for teachers and parents, a table of contents, and an index. Tractors is part of Jump!'s Machines at Work series.
