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

Samatha Martin
Hi! My name is Madison Soboul but I really like the name Elizebeth so... Anyways back on topic. I think Ck-12 has helped me become a better reader because I want to beat my record and speed. I think you could add a few things though, I think you should put some games where you answer questions to beat other students in your class.

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

This website was a great thing for us to us because it help us to do many of our assignments. The class and I really appreciate this website and what it has provided for us. My class and I have a new assignment to do and we use cK-12 because it makes us do different things on it to provide us and them with different information they need.

CK12 was a great resource for my middle school students because they were preloaded on their devices. Our internet connections were spotty at best in my classroom and CK12 provided a stable platform for me to teach and students to learn.

CK12.org has given me an online text and teaching materials that are NGSS aligned. This has enabled me to teach to the standards even though our school does not have a physical textbook. This has been such a lifesaver as a junior high science teacher!
