CK-12 has been an awesome resource! It provided much needed Biology resources for my daughter when she was a freshman.

CK-12 reading selection and real world applications are engaging and informative. I like that the content is aligned to NGSS and that the lexile level and academic language support make the content accessible to challenged learners. The PLIX interactives are graphically -appealing concept reinforcements.

IT HELPED WITH ALL OF MY HOMEWORK!!!!!!!!!!!!!! We have our lessons on the readings and they have really helped me learn. There is an occasional grammar issue and a misspelled word but other than that the practices and all the other things are really good for a 6th grade children's science class!! By the way HAPPY ANNIVERSARY!!!!!!!!!!!!!!!
