Free Textbooks Online at CK12 Flexbooks!
While at ISTE I stumbled upon the CK-12 booth on the exhibit hall floor. As soon as I saw the booth, I knew who they were. I'd visited their site before. I even created an account. But for some reason I never got around to sharing this great resource with others. My guess is "life" got n the way. Anyway, my apologies to you, my readers, because this is one heck of a site!
CK-12 is a collection of FREE (yes, that's right, FREE) online textbooks. The majority of the textbooks are in the math and science arena and are geared towards 6-12 grade students. But, there are also a few in other curricular areas. And, they are tied to a slew of state and national standards for you! Now, free online books alone would make CK-12 a terrific resource, but that's just the tip of the iceberg.
CK-12 are editable and customizable! Since all the material posted in the CK-12 library is posted under Creative Commons licensing, you can create your own books by grabbing a chapter here, a chapter there, a section here, and a section there/ You can create your own book (called a "flexbook" since it's use is so flexible), give it a title, and even share your new creation with others. According to the website,
"CK-12 allows one to customize and produce content by re-purposing to suit what needs to be taught, using different modules that may suit a learner's learning style, region, language, or level of skill, while adhering to the local education standards."Viewing the books doesn't require any signing in, but you will need a free account to create your own flexbooks or flag material for future use. Take a look. You'll be glad you did.
