Comments from Educators

This website was a great thing for us to us because it help us to do many of our assignments. The class and I really appreciate this website and what it has provided for us. My class and I have a new assignment to do and we use cK-12 because it makes us do different things on it to provide us and them with different information they need.

Hi! I have used Ck-12 to supplement the resources provided by my school district for years. Eventually, CK-12 became a resource that is recommended by my school district. Congrats and best wishes as you celebrate your 10th anniversary. Also, thank you!
