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
WOW! I just absolutely can not express so helpful CK-12 has been in my science teaching. We are moving away from our old standards and adopting NGSS. We currently do not have a textbook to use with the students and CK-12 has been a life saver! Thank you!

CK-12 helps out on 2 of my subjects and it makes learning easy. And, some of the videos are funny and it makes learning fun too. I love CK-12 because I met some people who work for it and they were so nice. CK-12 is awesome, and I think it should never be

My school district went full implementation with the new NGSS standards, but did not provide us with any curriculum. CK-12 saved the day!! Thank you CK-12!!!
Comments from Educators
As a homeschooling mom, it's always a struggle to find comprehensive material that is logical and easy to understand. That is not guaranteed even when money is spent. This is science based with great links and supportive data.

I love the webinars; they helped me get my classes set up in ck-12 and helped me create my own textbook. Although I publish my own workbook I often assign extra practice for the students on ck-12.
