What are your thoughts on Common Core Math?

Inspired by this article.
I, personally, don’t know anything about it. However, when my daughter was in elementary school (at a private school) in the 80’s they taught her some absurd way of adding, that had to do with drawing circles on a number, the number of circles corresponded with the number. Then they took their finger and touched all of the circles and counted them, and that was the answer.
To this day she can not add quickly and easily.
