The new primary edition of Units of Study in Reading is a comprehensive reading curriculum designed in alignment with the latest research about how kids learn to read, bringing science of reading components into every lesson.

The new units focus on structured whole class instruction, including:

You’ll find rich text sets and engaging storylines. You’ll find five units of knowledge-building curriculum per grade-level. Each unit is built around a sequence of challenging texts at the target Lexile level with vocabulary and comprehension support included. You’ll find embedded professional development for educators, summarizing the research around children’s reading development progression and providing instruction in the best methods to teach essential skills. What you won’t find is instruction anchored in three-cueing or that encourages kids to guess at words in lieu of decoding.

By pairing intense work in classrooms with ongoing deep study of research, Units of Study in Reading, K-2 offers a proven, scientifically based literacy approach that gives ownership to students and fosters powerful communities of learning.
