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

I am sincerely grateful to anyone out there who takes the time to provide kids with an education when they wouldn't have been able to get it in another way. CK-12 has definitely been a very helpful site, one that is fun, motivational, and most importantly

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.

CK-12 has helped me develop lessons that are interactive and present the material in a fun way. THANK YOU!
Holly
I have no textbooks to use in my classroom not even old ones to use as reference material for the students. Part of the educational standards is for students to be able to read content at grade level. How do you do this without books? CK12.org has been the provider of books and practice material. I am using it in all of my science classes except for AP Physics as those students are required to purchase a college textbook. Thank you CK12! Without your support and online material my job would be extremely difficult. Congratulations on 10 years of educational support.
