K-12 is still a new educational system here in the Philippines and its effectivity leads me to seek reliable resources and materials. And, indeed, CK-12 has answered my needs as an educator. Cheers, CK-12!

I have greatly appreciated the flex books and the connected practice sets! Those practice sets have been great help to my students that need just a little more time with material, and it saves me time from having to create more material resources myself!
