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 has been incredible. I've been using it to homeschool my middle-schooler for two years now, and it is unbeatable.

I have used it with Google classroom. When introducing a unit, I will have students view a video, take notes and follow-up with a discussion of what they learned. Students will complete some practice on the concept.

K-12 is still a new educational system here in the Philippines and its effectivity leads me to seek reliable resources and materials. And, indeed, CK-12 has answered my needs as an educator. Cheers, CK-12!

I have greatly appreciated the flex books and the connected practice sets! Those practice sets have been great help to my students that need just a little more time with material, and it saves me time from having to create more material resources myself!
