In this title, early fluent readers meet Sophie as she learns about her circulatory system. Read along as Sophie, her gym teacher, and her classmates discuss how our circulatory systems pump blood through our hearts and arteries, deliver oxygen to cells throughout our bodies, and remove waste such as carbon dioxide. Vibrant illustrations and carefully leveled text engage young readers in a supportive educational fiction reading experience. Children can learn more about the circulatory system using Fact Surfer, our safe online search engine that provides relevant, age-appropriate websites. This book also features diagrams, a review section, tools for teachers and caregivers, a glossary, an index, and a table of contents. Grasshopper Books offers simple, fun fiction for emerging readers. Sophie's Super Circulatory System is part of Jump!'s Let's Look at Body Systems! series.
