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 Educators
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 me find resources necessary for teaching standards and skills that are not in my current text book. It is supplemental material and websites that help me teach!

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!
Adam
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.

I'm a new teacher in an under-funded rural school district. I needed something to help me find quality materials for my classes. CK-12 literally saved me my first year. I will always be grateful for ck-12.
