The Teen Early Fluency Libraries build on the reading base of the Teen Emergent Reader Libraries(see pages 54 & 61). These books introduce readers to longer fiction and bridge the gap between emergent reading and early fluency. By the time older developing readers approach a second-grade reading level, they have a handle on the most basic literacy skills. They are ready to increase their fluency so that text flows and makes more sense. Fluency is closely tied to comprehension.
