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 am a high school biology and chemistry teacher. I assign ck-12 as a resource for students who struggle with concepts. I love the Real Life articles. The students get to understand why science is important. Thank you

CK12 works well with our 1-1 ipad program in our middle school. Students carry their work and flex books around in one small device! Yea, for saving their little spinal cords!

cK12 has helped me immensely with book resources for my students. Now they get to read smaller sections and not be so encumbered with such large science textbooks. The practice is becoming a very valuable tool with my students as well.

cK-12 has helped me with supplemental learning for my students in Science 8th grade and HS Chemistry class. It's great since the cK-12 lessons teach the same scientific vocabulary that are in my standards. Thank you for making education free, accessible and easy to accomplish on a smart phone. You are speaking the students' language!
