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

Hi ck-12!!! congratulations!! Im one year older then you!! But....... you guys helped me get a A in science class and my teacher was very impress with my work I have. I just started when I first became a 6th grader, and I was pretty mad I had too start a new website. I always had gotten a D in science and I love science, so it hurt me to see I was failing. But I came home that day and my mom told me to do it any way, so I signed up and then BOOM!!! I fell in love with this website!! My teacher always told me that I needed some help with science, so I wold get on ck-12 and asked a helper for some help. My teacher always told me I could study more of a topic to get caught up with the other students, so I would hop on ck-12 and read,study,watch,and write down the topic. Since I started ck-12 I have an A in science,I have honor roll, and help other kids with science too!! So now that I am almost finished, congrats on having your 10th birthday!! Without you guys I dont know were I would be.Happy birthday!!! -Jasmine Whitfield-

The CK flexbook has allowed our science department to have an up to date resource for most of our science classes. We have not had hardcopy text books for over 20 years.
Jim L.
It has been a great resource to use. I believe it benefits my students more than me, but it is certainly been a useful tool-resource.
Jim K.
CK-12 IS AMAZING! It deepened my child's knowledge and understanding involving geology, health, and much more! Thanks a bunch for always being there for my child when he most needed it.

I use it with special education students to find articles at lower reading levels. I also post links to articles on google classroom for students to read to reinforce their learning from class.

This is my first time at your website. I have demystified mathematics and looking to create and publish projects that enable students to become accountable for sense making to overcome previous barriers to progressive math studies to qualify with problem solving skills for 21st century careers from math-based STEM field curriculums for starting salaries of $60,000.

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.
Jennifer
CK-12 has helped my chemistry students to understand course concepts better. Students enjoy the interactive tutorials: these online tutorials help to differentiate learning in a more engaging way. I LOVE using CK-12 in my science classes!
