Comments from Educators

WOW! I just absolutely can not express so helpful CK-12 has been in my science teaching. We are moving away from our old standards and adopting NGSS. We currently do not have a textbook to use with the students and CK-12 has been a life saver! Thank you!

Lisa N.

ck-12 is helping me design my own text book for students. It is great that I can incorporate desmos activities and hands on learning.

Kande W.

Amruth L.

CK-12 helps me find resources necessary for teaching standards and skills that are not in my current text book. It is supplemental material and websites that help me teach!

M Hance

You have helped me create quick and modifiable text for my students!

Alexa C.

cK-12 has helped me with supplemental learning for my students in Science 8th grade and HS Chemistry class. It's great since the cK-12 lessons teach the same scientific vocabulary that are in my standards. Thank you for making education free, accessible and easy to accomplish on a smart phone. You are speaking the students' language!

Adam

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.

Kristin

I'm a new teacher in an under-funded rural school district. I needed something to help me find quality materials for my classes. CK-12 literally saved me my first year. I will always be grateful for ck-12.
