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

This has been an excellent resource for my class room. Our students do not have take home text books since we are a Title 1 school and money is limited. I have used this as a resource for homework and differentiation using your different workbooks. I have also used it as a large group presentation of a topic and then practiced using materials linked. I have also created several "webquest" type activities for use in our computer lab. Thanks for all of the hard work that went into this and I would love to see Social Studies/World/American history as fleshed out as the science is! Loved it!

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
