Why Students Love CK-12!
Take a look at what these students have to say about CK-12!
Wonderfull! like that it’s really to the point and precise. There’s lots of pictures and diagrams that are helpful when you are trying to learn.
My teacher made these textbooks, and it has everything that we need for this specific class.
It’s really accessible so it’s easy for the whole class to get on and we just go!
We use it every day because there’s something new that our teacher wants us to look at!
My CK-12 book is really nice because it has all of the information I need in it. Instead of hunting for all of the words and questions I have, it’s all there right in order

CK-12 really helped me last year teaching 7th grade social studies. The content, which was broken down by standard, helped me and my students get a better understanding of the material.

Comments from Educators
CK12.org has given me an online text and teaching materials that are NGSS aligned. This has enabled me to teach to the standards even though our school does not have a physical textbook. This has been such a lifesaver as a junior high science teacher!

CK-12 helped me by allowing me to access supplemental science curriculum for my students. It assisted me in the differentiation of instruction for my student body.
