Comments from Educators

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.

cK-12 has amazing textbooks with really helpful questions that help you understand what you are reading. I also really like the little quizzes because they help me learn some of the tougher concepts. The quizzes will review and review the question I'm stuck on and I find that extremely helpful.
