Program overview

Amplify CKLA is a core ELA program for Grades K–5 that delivers:

  • A unique research-based approach truly built on the Science of Reading.
  • A combination of explicit foundational skills with meaningful knowledge building.
  • Embedded support and differentiation that gets all students reading grade-level texts together.
  • Opportunities for students to see the strengths and experiences that all people share while also celebrating each others’ unique identities and experiences.
  • Authentic Spanish language arts instruction with Amplify Caminos.

How it works

Amplify CKLA teaches both foundational skills and background knowledge in Grades K–2 and combines them in Grades 3–5, in alignment with the Science of Reading.

  • In grades K–2, students complete one full lesson that builds foundational reading skills, as well as one full lesson that builds background knowledge.
  • In grades 3–5, students complete one integrated lesson that combines skills and knowledge with increasingly complex texts, close reading, and a greater writing emphasis.

Rich topics

Amplify CKLA builds knowledge coherently across subjects and grades.

Students make connections from year to year by exploring grade-appropriate subject-area knowledge and vocabulary in history, science, literature, and the arts, while learning to read, write, and think creatively and for themselves.

Science of Reading resources

Watching students learn to read? Magic. Knowing how they get there? Science.

As you consider your next core ELA program, it’s critically important to understand what the Science of Reading really means—and what it tells us about how to teach more effectively. Unlike other programs, Amplify CKLA was built upon these insights and practices, making it easier for teachers to implement this proven approach.
