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

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.

Louise P.
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.
