Why is Computer Science/Programming Important?

"Everybody in this country should learn to program a computer, because it teaches you how to think" -Steve Jobs

Improves abstract thinking, problem solving, and problem decomposition

Opens doors to many jobs. CS classes are the largest classes at Harvard and Yale, attended by students from all majors, and CS is the highest median salary major.

Helps them feel comfortable with using computers

Drives improvement in other coursework such as Science and Math projects

Why Should Children Learn to Code Early?

Kids will learn faster and better while they're young, just like any language. They also have the time to do so now, as they will get busier starting in high school.

An empowering skill that allows them to confidently create, problem solve, and form solutions in a world of limitless possbilities
