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 has helped me breeze through geometry in a private school which did not offer the class. The ability to do everything on my own gave my teacher the time he needed to teach his other classes and helped me earn my high school credit for when I advance

The CK flexbook has allowed our science department to have an up to date resource for most of our science classes. We have not had hardcopy text books for over 20 years.

I love cK12! I have used it in my high school science classes for 4 years now. I love how well the readings coordinate with the interactives and I love how I can integrate it into my Edmodo class pages as well. I REALLY love how I can find the same topic at different reading levels and in Spanish so that I can make sure every one of my students can learn science content and themes at any skill level.

CK-12 has not only been a great resource for my students, but it helped me land my first job out of college! I used a CK-12-created NearPod presentation in a lesson I taught to a panel of interviewers in my final round. Thank you for the great work!
