Entries begin with a short third-person narrative relating to the subject. Chapters break down topics into smaller pieces, often which contextualize the topic for modern-day readers. For example, 3D Printing provides several chapters about the different fields that use the technology, and Little Rock Nine describes, step-by-step, the struggle for school integration. While complex topics, such as race and germ warfare, are featured, brief chapters and sentences with three-to-five words help simplify each subject. A controlled vocabulary also makes this series accessible for readers on a first grade reading level. Vivid covers, along with full-page color photographs and graphics, make each book visually appealing. Nonfiction text features including bold words, a short glossary, and highlighted fun facts, are sprinkled throughout. VERDICT With engaging topics, this highly readable series can be used for research by upper elementary and middle school hi-lo readers.
