This document discusses early literacy development from birth through elementary school. It covers stages of literacy development, how reading and writing develop, and developmentally appropriate practices to support literacy. Some key points include: literacy is first modeled at home, stages include awareness/exploration, experimental reading/writing, and independent reading/writing. Creating literate environments, shared reading, reading aloud, and play-based activities promote literacy development. Teachers should consider students' backgrounds and use culturally appropriate practices.
