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 reading selection and real world applications are engaging and informative. I like that the content is aligned to NGSS and that the lexile level and academic language support make the content accessible to challenged learners. The PLIX interactives are graphically -appealing concept reinforcements.

I am using CK-12 in both my chemistry and physics classes this year which is my 37th year in teaching. When I tell people I use CK12 to make customizable free electronic textbooks, people are very surprised that it is possible.

Margaret B.
I've been working with a student who is preparing to take a nursing exam. It it difficult to find a single website that combines all the subjects on the exam - CK-12 is one of the few and definitely the most comprehensive. The breadth of content on CK-12 is remarkable. The material is almost always of a very high quality. I'm happy to have discovered the site and will continue to incorporate its resources into my future teaching.
John P.

You have helped my teachers by provided a large and reliable source of information for them, as well as a cite that their students can go on and explore. In turn, that helps me.

I'm a first year teacher in an impoverished school district. Having virtual tools is the best way to close the achievement gap between my district and well-funded schools. Thank you!
