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 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 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.

This cite allows me to provide practice for my students that isn't always just another worksheet. We all like the immediate feedback that this site provides.
