CK-12 Recap from ISTE and NCSC 2013

STEM and CK-12

Two weeks ago, a few of us at CK-12 Foundation had the pleasure of attending and exhibiting at ISTE in San Antonio, Texas and NCSC in Washington DC. We had the opportunity to meet with lots of familiar faces as well as spread the news about CK-12 STEM content to hundreds of new connections!

This math concept gem has been around for a few years, but we couldn't help but get excited when we found it posted by the Washington Post today. We thought you'd find it fun to use simple arithmetic and math concepts to calculate your age. Try it!

Last week, in celebration of Teacher Appreciation Week, we asked you to thank your teachers in our Say Thanks campaign.

We were so excited to receive the thousands of submissions from students who care for their teachers so much! Students thanked their teachers for helping them to learn algebra, for drilling home chemistry concepts and for providing physics lessons that have helped them get into the best colleges.

Making Biology Interactive - on your iPad!

describe the image

When we first started our venture into the realm of free digital textbooks, our goal was to pioneer the creation and distribution of the "next generation" textbook.  With the FlexBook, a free comprehensive, fully customizable, standards-aligned digital textbook complete with embedded multimedia objects, we met that goal. But realizing new technologies like Apple's iBook Authoring platform would allow for new types of interactivity in our textbooks, we let our creative juices flow. Part of maintaining the philosophy of creating the "next generation" of anything is continuing to innovate. So, on we work - trying other exciting ways of bringing the best learning experience to students worldwide, all completely free.

20 Million Thank You's!


CK-12 Foundation has reached a major milestone today! For the past 2 years, we have strived everyday to ensure students the world over don’t fall by the wayside simply because their schools, in the face of intensifying budget cuts, are unable to provide quality educational resources. Today we proudly announce that between content downloads and pageviews we have delivered more than 20 million learning opportunities to students everywhere - without charging a cent.  11 million of those coming in the last 4 months alone! For that, we wish to sincerely THANK YOU - our growing community of teachers, administrators, students, and other users. Without your voice, support, and enthusiasm for CK-12, we would never have been able to affect so many students’ lives. To all of you that have shared our free offerings, we appreciate you.
