A chapter book is a type of children's literature designed for early readers, typically aged 7 to 10 years. These books are longer than picture books but shorter than middle-grade novels, usually containing 60 to 100 pages. They are divided into chapters, making it easier for young readers to digest the story in manageable sections. Chapter books often feature illustrations, but they are less frequent than in picture books. The stories usually include relatable characters and themes, helping children develop their reading skills and confidence. Popular examples of chapter books include series like Magic Tree House and Junie B. Jones.
