This appealing illustrated series explains the stages of animal and plant life cycles in a simple way for very young readers. Each book features engaging artwork showing the stages an animal goes through from egg or baby to adulthood, and a plant from seed to being full-grown. Easy-to-understand text accompanies each image explaining the process of each stage in an accessible way. A full image of the entire life cycle is presented at the end. A link printed inside each book gives readers access to Crabtree Plus, a website featuring supplemental digital content, including interactive activities that reinforce and extend key series' concepts. Free downloadable Teacher's Guide available.
