CK-12 Resource Series Updated in NCLOR

CK 12 logoDue to a resource reorganization at CK-12, the NCLOR needed to re-catalog all the resources available from the CK-12 foundation. The FlexBooks® currently available (72), have now been downloaded to the NCLOR directly in PDF and ePub formats. To view the files you will need a pdf reader or an iOS device, Android device or ePub reader to view the ePub files. All older versions of the resources in the CK-12 series have been archived.

FlexBook® textbooks are CK-12’s open source digital textbooks.

The CK-12 Foundation is a non-profit organization with a mission to reduce the cost of textbook materials for the K-12 market both in the U.S. and worldwide. Using an open-content, web-based collaborative model termed the FlexBook®, CK-12 intends to pioneer the generation and distribution of high-quality educational content that will serve both as core text as well as provide an adaptive environment for learning.
