Stories that Build Knowledge      

Open-and-go U.S. History books and lessons for upper elementary.

Fits Your Schedule

Each unit is divided into short segments you can spread across days or teach in a single block. Open to page one and go. The book, Teacher's Guide, and Student Journal do the planning for you.

Engages Your Students

Students step into the role of history detective — investigating historical evidence, debating perspectives, and reading compelling stories that expand their world. The best part of history is the story.

Builds Strong Readers and Knowledgeable Citizens

Strong readers need knowledge, not just decoding skills. Science of Reading strategies are woven directly into the book, developing fluency and vocabulary, while content-rich narratives and nonfiction paired readings build the background knowledge that makes real comprehension possible.

Knowledgeable citizens are built through practice. Students investigate evidence, debate perspectives, draw their own conclusions, and develop the habits of mind that democracy depends on.

Rigorous content. Real skills. Measurable results.
