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

I did a seventh grade project using your website. It was about the different body systems and your site explained it good. Keep it up! Looking forward to coming back and seeing what's new.

CK-12 helps me understand science a lot better than just randomly taking notes. There's pictures and explanations, too, making it easier to understand the text.

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.
