CK-12′s FlexBook® textbooks are unique in that we aim to provide a comprehensive K-12 online curriculum that conforms to curriculum standards. We currently develop content for science, technology, engineering, and math (STEM) textbooks. Our FlexBook® system is the only free web-based application for adapting open-source material and creating customized textbooks.
