The FKB Ultimate K-12 OER List

FKB OER CollectionThis is simply as stated our ultimate resource list of direct links to the websites of our pre-primary, primary, and secondary open educational resources providers, if we have missed anyone please contact me or leave a comment I will review and add them!

Resources are listed in order of their volume of content from our users perspective, i.e comprehensive textbooks and written resources.

About OER’s:  Open Educational Resources (OER’s) are exactly as stated, educational resources that contain an open license for sharing, this can be creative commons, or public domain, or any similar copyright. Thanks to the OER movement, educational material is becoming more open, which means people everywhere have more access to material at no cost, moving us towards 2030 UN SDG 4 – quality education.

The sources below are what we have used primarily for the compilation of our Free School Textbooks for K-12 resources collection.
