To think, people believe this common core math actually works.

I know what you're doing to come up with this remark, but it's wrong. It will be FIVE years since release. You need to count the span, not your fingers.

2011 > 2012 = 1

2012 > 2013 = 1

2013 > 2014 = 1

2014 > 2015 = 1

2015 > 2016 = 1

Add up all the "1s" and you get 5.

Common core math failure.
