CK-12′s FlexBook platform® allows you to create free, high-quality, and fully customizable textbooks.
You can view the book online or print a book, in whole or in part.
You can read and annotate a FlexBook® textbook on an iPad, Kindle, or other ePub-compatible device.
You can use our content in whole or in part.
You can write a book from scratch.
You can edit our books, build upon them, share them, and print them. They are aligned with US, California, and Common Core textbook standards, and since our textbooks are digital, we can easily update them, unlike a traditional textbook.
You can add or delete images, videos, graphics, web links and animations (either your own, or from the web) to enrich the student’s experience.
You can share published titles via Facebook and Twitter.
You can share all titles via PDF and HTML links (each has different attributes which serve different purposes).
You can carry your textbook in your pocket–on a flash drive, hard drive, or DVD (no need to lug a big heavy book anymore).
