Designed to build a base of content knowledge

CKLA connects engaging topics within and across grades, building knowledge and connected vocabulary for deep comprehension:

  • Knowledge domains build on prior learning.
  • Repeated exposure and reinforcement.
  • Coherent vertical and horizontal design.

Brings content to life, sparks passion

CKLA combines engaging and increasingly complex informational and literary texts, with a focus on expanding knowledge across all content areas:

  • Rich texts across science, social studies, literature, and the arts.
  • Close reading, writing, and text-based discussions grounded in relevant content that supports knowledge building.

Knowledge strand

Building students’ knowledge and vocabulary while they are still learning to read is crucial for long-term success. At the heart of this strand are authentic fiction and nonfiction texts that teachers read aloud. These texts are grouped in knowledge domains that create interactive opportunities to question, discuss and share ideas centered on text. This strand ensures students are well prepared when they transition from learning to read to reading to learn.

Skills strand

Teach reading and writing in tandem. These lessons support reading and foundational skills through daily instruction in phonemic awareness, spelling patterns, decoding with engaging decodable texts, writing mechanics and writing structure and processes. The Skills Strand fully accords with the findings of the National Reading Panel and the Reading Foundational Skills section of the Common Core State Standards.


Blending print and digital materials, CKLA ensures teachers have resources at their fingertips to help plan and deliver instruction. Hands-on training on the program’s unique pedagogy and unlimited technical and instructional support accompany every implementation. Each classroom kit accommodates differentiated reading and writing instruction with components for 25 students.
