The document discusses how creating print-rich environments and encouraging free voluntary reading leads to improved reading achievement, comprehension, vocabulary, and writing ability. It summarizes several studies that found correlations between reading achievement and factors like the number of books students have access to, the amount of time parents spend communicating with their children, and how engaged students are with reading. The document provides recommendations for what families can do to support reading, such as providing access to reading materials at home, allowing choice in materials, providing dedicated reading space and time, and supporting reading through activities like reading aloud, being role models, and talking about books.
