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 Students
I am a high school biology and chemistry teacher. I assign ck-12 as a resource for students who struggle with concepts. I love the Real Life articles. The students get to understand why science is important. Thank you

With our "bring your own device" initiative, our corporation no longer buys textbooks. Thank you for giving me a way to still provide my students a way to have a good information source they can continually turn to.

Provided an integrated learning platform that permits me to choose the portions of your texts that fit my classes. One of my courses has been redesigned around ck-12 materials!

CK-12 has helped me positively impact student achievement in my classroom! I have found numerous problems that I have used with my students, discovered ways to improve my instruction, and developed a clearer understanding of how to target my instruction and interventions!

I have only recently discovered this wonderful site. I am using it as an actual teaching resource, whereby I use it to flip my class. So students will work through the content at home, regroup in class to discuss topics and issues and then they write the

CK12 works well with our 1-1 ipad program in our middle school. Students carry their work and flex books around in one small device! Yea, for saving their little spinal cords!

cK12 has helped me immensely with book resources for my students. Now they get to read smaller sections and not be so encumbered with such large science textbooks. The practice is becoming a very valuable tool with my students as well.

made it easier to teach lessons
Comments from Educators
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.

Cooper L.
I can barely remember how I used to teach with an old dusty textbook. I have kept those around, but now I use them in a special activity: I have students rip out pages to underscore the fact that science is constantly changing. Traditional text, especially in science, are obsolete before they even ship. Needless to say, they are also very expensive. I have also turned several colleagues onto CK12 and now your awesome products are used in several grades here.
