3 x 4 = 11 ? Incorrect, right? Well, not according to 'Common Core', the latest curriculum in America's schools mandated by the federal government.

Common Core's critics say that it dumbs down math standards, doing so by gutting basic math requirements and, in many cases, by accommodating 'fuzzy math', in which explanations are considered more important than correct answers.

In the video the instructor says it’s alright if a student says 3 x 4 = 11. What matters, she explains, is not the right answer, but a good explanation of the 'reasoning' behind whatever answer the child chooses to give.

The government's Common Core curriculum has been adopted in Louisiana in language arts and math. It is also being taught in 45 other states.
