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 a lot. My biology teachers occasionally assigns us CK-12 assignments to do. One time she made us do 23 different lessons! The whole point is that CK-12 is an easy way to learn and to have fun while doing it. Also I think that if I could change anything about CK-12 I wouldn't even do a thing.

CK-12 is a terrific resource. I'm the science chair at an independent school in Los Angeles. We have been moving away from physical texts for a while and CK-12 is the best online alternative in our opinion. Students enjoy the varied learning formats and teachers appreciate the class management options. Happy Birthday CK-12!!!!

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
