Ck12 has revolutionized the manner in which I teach. This magnificent educational asset has taken the text book out of the classroom and made learning accessible to students anywhere there is a internet connection

I am a first-year chemistry teacher in an under-funded charter school. Our books are almost 10 years old and our lab doesn't have a complete stock. While searching to remedy some of these challenges, I stumbled upon CK-12 which offers a solution to a semi-outdated text and no online option for students who have grown up in the technology age. Thank you for allowing me to add your site as a resource and have options for useful tools to teach my students. Your site helps to make me a better teacher.

ck-12 is an amazing resource that provides up to date information that I can use to supplement our science textbooks. It also has leveled activities which helps when differentiating instruction. Keep up the great work!

cK-12 has amazing textbooks with really helpful questions that help you understand what you are reading. I also really like the little quizzes because they help me learn some of the tougher concepts. The quizzes will review and review the question I'm stuck on and I find that extremely helpful.
