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

ck-12 is an amazing resource that provides up to date information that I can use to supplement our science textbooks. It also has leveled activities which helps when differentiating instruction. Keep up the great work!

I am a first-year chemistry teacher in an under-funded charter school. Our books are almost 10 years old and our lab doesn't have a complete stock. While searching to remedy some of these challenges, I stumbled upon CK-12 which offers a solution to a semi-outdated text and no online option for students who have grown up in the technology age. Thank you for allowing me to add your site as a resource and have options for useful tools to teach my students. Your site helps to make me a better teacher.
