  • The CK-12 FlexBook® library currently includes STEM (science, technology, education, and mathematics) curriculum for grades 6-12. Additionally, there are SAT Preparation materials, English books, and more! The library is growing all the time. We have plans to develop many more resources, and one day will offer a comprehensive curriculum for grades K-12.
