Geodes® Classroom Libraries


Engaging, accessible, knowledge-building books for emerging and developing readers

Reading to Learn While Learning to Read

Rooted in the belief that children are capable of reading to learn while learning to read, Geodes®, published by Great Minds® in association with Wilson Language Training®, are a collection of accessible, knowledge-building books for emerging and developing readers.

Named after the modest-looking rocks that contain countless crystals inside, Geodes hold a surprising amount of interesting, complex, and beautiful qualities inside each book. Students practice applying taught skills and concepts while learning about important ideas in science, history, and the arts. 

These texts combine Wilson’s expertise in foundational reading skills instruction and Great Minds’ experience at building students’ content knowledge. Geodes align with both the scope and sequence of Fundations® and the module topics in Great Minds’ English language arts curriculum Wit & Wisdom™.

About the Readables

What does the term “readable” mean? Geodes are “readable texts” because, with specific decoding strategies coupled with explicit instruction in vocabulary and content knowledge, they are wonderfully accessible to students with emerging reading skills. While written for emerging and developing readers, the books provide an authentic reading experience that builds content knowledge about science, history, and the arts, fostering intellectual curiosity.

Unique Features of Geodes

Each of the four modules cover a specific topic, and the sets within a module cover a subtopic.

  • Topics from many content areas and genres build content knowledge and context.
  • Texts are organized in grade-level appropriate sets, with each set building a “mental shelf.”
  • Geodes are 80 percent decodable or higher at a designated point in the Fundations scope and sequence.
  • Decodable words include previously taught and newly taught phonetic concepts that align with Fundations.
  • Recognizable words include previously taught and newly taught Fundations “Trick Words.”
  • Pre-selected content words related to the topic are taught for sight recognition. Including these, the decodability of the text is greater than 80%, making them “readable” and accessible.

Using Geodes

Geodes align to the Fundations Scope and Sequence, but also can be used outside of Fundations lessons or incorporated into fluency practice.

Level-specific Libraries

Geodes’ texts are organized in grade-level appropriate sets. Each library is organized into topical modules that interest young minds.

The Geodes books provide an authentic reading experience that builds content knowledge about science, history, and the arts, fostering intellectual curiosity.

Geodes are available in Levels K, 1, and 2 to align with the Fundations scope and sequence.
