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.

Series Components

There are five Units of Study in Reading for each grade level, and each unit represents four to six weeks of teaching.

About the Units of Study in Reading, K–2

Units of Study in Reading, Grade K

The Units of Study in Reading for Kindergarten are designed to help you introduce your students not only to the reading workshop but also to school. 

In Unit 1, We Are Readers, your task will be to get your kids excited about reading and to help them feel comfortable in the classroom. Students will work to develop essential pre-reading skills, and they’ll practice these skills both on their own and with their peers. In Unit 2, Sharing Reading, you’ll channel your students to pay attention to the words in books. Students will learn to read text from left to right, one word after another, with one-to-one correspondence. They’ll also draw on their growing knowledge of high-frequency words and of the alphabetic code to read familiar patterned books. In Unit 3, Super Powers: Reading with Phonics and Sight Word Power, you’ll rally kids to do the hard work of decoding. They will learn to use new superpowers: “slider power”—the ability to slide through the sounds of words and blend them back together, “think power” to notice and wonder about the content of what they are reading, and “fix-it power,” which helps kids look closely at a challenging word and check to make sure it makes sense. Throughout Unit 4, Boosting Reading Power, students will continue to build on the superpowers they attained in the first three units. You’ll help give these powers a “turbo boost” to help young readers tackle texts with greater complexity. Finally, in Unit 5, Becoming Avid Readers, you’ll build upon and celebrate the journey youngsters have taken since the start of the year.

Units of Study in Reading, Grade 1

The Units of Study in Reading for Grade 1 are designed to help your students continue to build on all of the skills they learned throughout kindergarten, and to help them develop good reading habits they’ll carry with them through the rest of their academic careers and beyond. 

In Unit 1, Building Good Reading Habits, it will be your job to get students excited about reading and to model the habits of good readers. Students will continue to develop their decoding skills and will be able to monitor for sense and self-correct with increased accuracy. Unit 2, Word Detectives, begins with the discovery of a top-secret, mysterious envelope from the Super-Secret Detective Agency, inviting your class to take on the role of word detectives. They’ll continue to build vocabulary, building up a bank of snap words, and they’ll practice monitoring for comprehension. Across Unit 3, Learning about the World, you’ll balance your teaching between decoding work and the nonfiction reading skills that will be important in helping children learn from books. Unit 4, Readers Have Big Jobs to Do, marks an important juncture in the reading lives of many of your students as they make the shift from a reading diet of decodable books and carefully selected leveled texts to one of less-controlled trade books. Finally, in Unit 5, Meeting Characters and Learning Lessons, you’ll teach some essential comprehension strategies, lifting the level of readers’ work from earlier units.

Units of Study in Reading, Grade 2

The Units of Study in Reading for Grade 2 are built to remind students of all the incredible skills they learned in first grade and to transition them into the big kid work of being a second grader. 

In Unit 1, Becoming a Big Kid Reader, you’ll teach your students how to read with greater fluency and help them develop strategies to become efficient and flexible word solvers as they encounter trickier words. Throughout Unit 2, Becoming Experts, you’ll invite kids into the fascinating world of nonfiction reading, ushering them into the unit by suggesting that good readers of nonfiction are interested in everything. They’ll learn to read closely, with wide-awake attention to detail. At the start of Unit 3, Tackling Longer Words and Longer Books, you’ll ask for your students’ help in refurbishing your classroom library. Throughout this process, students will begin to work through more difficult words and will practice scooping up longer phrases. In Unit 4, Stepping into the World of the Story, you’ll invite students to think about the incredible power that reading has to take us on adventures, on field trips, to faraway places, and to familiar neighborhoods. Finally, in Unit 5, Growing Knowledge Together, you’ll amplify the importance of reading partnerships, helping your students talk and collabo­rate in new and more rigorous ways. Students will work independently and with reading groups to make sense of more challenging texts.

United We Learn

Launch Students into Collaborative Nonfiction Reading

With an emphasis on social justice and culturally responsive teaching, United We Learn launches students into collaborative nonfiction reading.

In this stand-alone unit, the importance of partnerships is amplified, with a focus on helping young learners talk and collaborate in new and more rigorous ways. This spotlight on talk and collaboration is part of a larger focus on classrooms as generous, supportive, culturally responsive learning communities.

United We Learn includes 19 sessions across three bends, one of which is a video session accessible in Heinemann Flight. Each session builds in such a way that the work of one bend provides a foundation for the work of the next. By the end of this unit, children will have learned the power of collaborating in partnerships and clubs to grow knowledge while thinking critically about texts, their identities, their peers, and the world.

This unit has been designed to be used in both second- and third-grade classrooms, and you’ll find tips throughout the unit on how to differentiate when needed.

Jump Rope Readers Decodable Books

The Jump Rope Readers are a series of high-interest fiction and nonfiction decodable books that gradually and systematically introduce beginning readers to new letter-sound correspondences and high-frequency words.

The Jump Rope Readers are arranged into different series, each starring a distinctive main character that students will enjoy getting to know. The fiction series begins very simply, introducing a new phonics concept along with one or two high-frequency words in each book. From there, each book builds on previous books, introducing one or two letter-sound correspondences along with a couple new high-frequency words.

Once students finish a fiction series, they can move to the corresponding nonfiction books. The nonfiction decodables offer a sequence of landings for readers to pause, review, and practice what they have learned up to that point, while learning about new content in a new genre.
