Due 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 All older versions of the resources in the CK-12 series have been archived.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.
Except as otherwise noted, all CK-12 Content is made available to users in accordance with the Creative Commons Attribution-Non-Commercial 3.0 Unported (CC BY-NC 3.0) License (http://creativecommons.org/licenses/by-nc/3.0/), as amended and updated by Creative Commons from time to time (the “CC License”), which is incorporated herein by this reference.
