In this title, early fluent readers meet Mia, a girl who loves to play basketball, as she learns about her muscular system. Read along as Mia and her mom discuss how our muscles work together to help us move our bodies, the three different kinds of muscles and their functions, and how they repair and strengthen themselves. Vibrant illustrations and carefully leveled text engage young readers in a supportive educational fiction reading experience. Children can learn more about the muscular system using Fact Surfer, our safe online search engine that provides relevant, ageappropriate 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. Mia's Mighty Muscular System is part of Jump!'s Let's Look at Body Systems! series.
