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

I was able to create worksheet practice for my students.The videos available were also helpful in helping students review concepts

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!

I work at a Stem High School - Hudson Valley P-Tech in NY. Our mission is to connect math to the real world for our students. I liked your distance formula lesson and right now I am looking at your amplitude, Freq & period info. Keep up the good work!!

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!
