You have helped my teachers by provided a large and reliable source of information for them, as well as a cite that their students can go on and explore. In turn, that helps me.

CK-12 has been an incredible resource in my classroom to help improve student learning. Bell work activities, extension questions, supplemental practice problems, and application graphics have all been utilized by myself and my students. Thank you for all

CK-12 has not only been a great resource for my students, but it helped me land my first job out of college! I used a CK-12-created NearPod presentation in a lesson I taught to a panel of interviewers in my final round. Thank you for the great work!

Alexis M.

I am sincerely grateful to anyone out there who takes the time to provide kids with an education when they wouldn't have been able to get it in another way. CK-12 has definitely been a very helpful site, one that is fun, motivational, and most importantly

Ck-12 has helped me understand some of the things that are happening in my chemistry pre-ap class. Without Ck-12 I do not think that I would be doing well in class. Thank you and keep up the great work.
