Welcome to the CK12.org website (the “Site”) which is owned and operated by CK-12 Foundation, a California non-profit corporation(“CK-12” or “we”). CK-12′s mission is to reduce the cost of textbook materials for the K-12 market both in the U.S. and worldwide. Using an open-source, collaborative, and web-based compilation model, CK-12 pioneers and promotes the creation and distribution of high-quality,adaptive online textbooks that can be mixed, modified and printed (i.e., the FlexBook™ textbooks). The Site is designed to serve as both an information resource and an application platform for K-12 teachers, educators and students who wish to join our online community.
