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 have used it with Google classroom. When introducing a unit, I will have students view a video, take notes and follow-up with a discussion of what they learned. Students will complete some practice on the concept.

I've been working with a student who is preparing to take a nursing exam. It it difficult to find a single website that combines all the subjects on the exam - CK-12 is one of the few and definitely the most comprehensive. The breadth of content on CK-12 is remarkable. The material is almost always of a very high quality. I'm happy to have discovered the site and will continue to incorporate its resources into my future teaching.
