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

The CK flexbook has allowed our science department to have an up to date resource for most of our science classes. We have not had hardcopy text books for over 20 years.

It has been a great resource to use. I believe it benefits my students more than me, but it is certainly been a useful tool-resource.

I use it with special education students to find articles at lower reading levels. I also post links to articles on google classroom for students to read to reinforce their learning from class.

CK12 was a great resource for my middle school students because they were preloaded on their devices. Our internet connections were spotty at best in my classroom and CK12 provided a stable platform for me to teach and students to learn.

CK-12 has helped my chemistry students to understand course concepts better. Students enjoy the interactive tutorials: these online tutorials help to differentiate learning in a more engaging way. I LOVE using CK-12 in my science classes!
