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
Comments from Students
CK-12 has been incredible. I've been using it to homeschool my middle-schooler for two years now, and it is unbeatable.

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 actually started taking notes because of all the real world examples in science because the info doesn't click if I don't relate. Since studying and taking notes on this site every single test I have studied for on here, I passed!

Comments from Educators
I'm a first year teacher in an impoverished school district. Having virtual tools is the best way to close the achievement gap between my district and well-funded schools. Thank you!

I am an italian teacher of chemistry. I like my work and new teaching strategies. Often some of my students can speak English better than italian and as I know how much important english is, I invite them to keep an english lecture on a particular topic for the whole class, including me. Your videos, tests and documents are really helpfull in this! Thank you very much
