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

Comments from Educators
It has saved our district thousands of dollars potentially allowing the district to use the money for other needs. It has allowed the students to use the book on their personal devices, but we also were able to print hard copies at reasonable prices to th

I learned about CK-12 this year from the previous science teacher in my position at my new school. I have used CK-12 resources for all three of the subjects that I teach and my students just recently told me they would rather use CK-12 than Khan Academy.

Cyril F.
I use ck-12 in my classroom. The school does not provide textbooks for the students, so I use the textbooks from ck-12.org for all of my classes except for AP Physics.
Cynthia B.
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.
