Comments from Educators

In the digital age I find have a paper textbook for a dynamic science world limiting and not budget wise. Thank you for making this service available! I find it very useful as a resource in my classroom.

Amazing resource! With so many statewide educational budget cuts, it has been extremely difficult to find quality teaching resources. cK-12 has filled that niche quite nicely! I would recommend this valuable site to anyone. Thanks!
