Comments from Educators

I have been able to use CK12 to allow my homeschooled student to explore and expand on concepts we have studied in greater depth.

ck12.org has been a great find! Free, quality on-line textbooks that can be customized as desired. PLUS on-line 'instant' quizzes that provide feedback and links to my LMS - a true TREASURE! Congrats on 10 Years!!!

Donna E.

CK-12 provides great mini lessons, which can be used as Bell Ringers or introductions to lessons.

CK-12 has helped liberate my classes from a traditional textbook. Now my students can read the content they need at their own level.

My students love CK-12's Braingenie, and I do too. This is my 2nd year using Braingenie, and I have helped several other teachers become acquainted with it too. I especially love that I can create the goals for my students and then track their progress through the reports.

CK-12 has given my kids a great foundation of knowledge in the subject they are studying, while allowing me the opportunity to add additional information and videos if needed.

Denise R.

I would like to have access to the webinar to use some of the 3-5 resources. I liked the tremendous amount of activities I can use with my fourth grade class.
