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 Students
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.

My students love CK-12's Braingenie, and I do too. This is my 2nd year using Braingenie, and I have helped several other teachers become acquainted with it too. I especially love that I can create the goals for my students and then track their progress through the reports.

CK-12 has given my kids a great foundation of knowledge in the subject they are studying, while allowing me the opportunity to add additional information and videos if needed.
Denise R.
I would like to have access to the webinar to use some of the 3-5 resources. I liked the tremendous amount of activities I can use with my fourth grade class.
Denise H.
I love the webinars; they helped me get my classes set up in ck-12 and helped me create my own textbook. Although I publish my own workbook I often assign extra practice for the students on ck-12.
Deb M.
As a homeschooling mom, it's always a struggle to find comprehensive material that is logical and easy to understand. That is not guaranteed even when money is spent. This is science based with great links and supportive data.
