CK 12 is a great resource to use both in the classroom and for homework. The links to the Canvas platform are very advantageous to me and cut my grading time in half.

I use CK-12 for my science, math, and asking questions. Since I am home schooled this website is a great thing for me because it is a boost on my education and for others who are like me. I really like that you can ask questions and answer them as well. Y

Hi ck-12!!! congratulations!! Im one year older then you!! But....... you guys helped me get a A in science class and my teacher was very impress with my work I have. I just started when I first became a 6th grader, and I was pretty mad I had too start a new website. I always had gotten a D in science and I love science, so it hurt me to see I was failing. But I came home that day and my mom told me to do it any way, so I signed up and then BOOM!!! I fell in love with this website!! My teacher always told me that I needed some help with science, so I wold get on ck-12 and asked a helper for some help. My teacher always told me I could study more of a topic to get caught up with the other students, so I would hop on ck-12 and read,study,watch,and write down the topic. Since I started ck-12 I have an A in science,I have honor roll, and help other kids with science too!! So now that I am almost finished, congrats on having your 10th birthday!! Without you guys I dont know were I would be.Happy birthday!!! -Jasmine Whitfield-
