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 learned about CK-12 this year from the previous science teacher in my position at my new school. I have used CK-12 resources for all three of the subjects that I teach and my students just recently told me they would rather use CK-12 than Khan Academy.

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.

I use ck-12 in my classroom. The school does not provide textbooks for the students, so I use the textbooks from ck-12.org for all of my classes except for AP Physics.

There have been available lessons that have helped my students have a better understanding of the material.
