This is my first time at your website. I have demystified mathematics and looking to create and publish projects that enable students to become accountable for sense making to overcome previous barriers to progressive math studies to qualify with problem solving skills for 21st century careers from math-based STEM field curriculums for starting salaries of $60,000.

CK12 was a great resource for my middle school students because they were preloaded on their devices. Our internet connections were spotty at best in my classroom and CK12 provided a stable platform for me to teach and students to learn.

I found CK-12 when I couldn't find the answers for my homework. Best thing that could have happened, even if my teacher introduced me to it in a later time. The content is amazing! It's helped alot throught the school semester.

It has helped me learn different concepts of Earth Science.

In the past, ck-12 has been a trustworthy and colorful resource that I could always rely on if I was struggling with a concept in class. In geometry this year, we're actually required to use it, and it certainly helps me to learn concepts well.
