Each leveled set contains 8 books (16 pages each) with full color photos. Levels are color coded and indicate the Guided Reading (G.R.) and the Development Reading Assessment (DRA) levels: Gold (G.R. L, N; DRA 22-28). The nonfiction readers are written at the same level or just a step more difficult than the fiction. The nonfiction series expands on topics. By the Gold level, students will predict content and handle new words in lengthy sentences.
