Caleb Bonham, editor-in-chief of Campus Reform, recently took to the streets of Boulder, Colorado, with the specific purpose of frustrating people with Common Core math. Needless to say, he accomplished his goal.

Apparently using an actual Common Core math problem, Bonham used a small dry erase board to walk unsuspecting individuals through the steps — and there are many.

After finally solving the simple subtraction problem, Bonham asked the participants if the Common Core method represents the most efficient way to teach mathematics to the next generation of students.

“No,” one man responded immediately.

“It’s inefficient, you’re wasting time,” another said.

One woman, who was holding a baby who could theoretically be required to learn Common Core-style math in the future, simply said, “I don’t like it — at all.”
