Engages and Empowers Families

trade quality texts

School-aged children are expected to learn an estimated 3,000 to 4,000 words each year (Nagy and Herman, 1987; D’Anna, Zechmeister, and Hall, 1991). Learning this volume of words in such a short period requires some amount of direct teaching but is largely dependent upon incidental learning through independent wide reading and other activities that immerse students in language.

–Cobb & Blachowicz, 2014
