I am homeschooling my 8th grader for the last trimester. I am looking for things to make his education complete and fun.

CK12 works well with our 1-1 ipad program in our middle school. Students carry their work and flex books around in one small device! Yea, for saving their little spinal cords!

Kristin D.

cK12 has helped me immensely with book resources for my students. Now they get to read smaller sections and not be so encumbered with such large science textbooks. The practice is becoming a very valuable tool with my students as well.
