Watch This Math Teacher Take Almost an Entire Minute Explaining How to Add 9 Plus 6 Using Common Core Math

A simple addition problem seems to become a little more complicated under Common Core. That is made very clear in a new “Homework Helper” segment that recently aired on WGRZ-TV in Buffalo, New York.

In the new educational segments, local teachers attempt to help confused parents better understand their children’s Common Core homework. In the introductory segment, a math teacher takes nearly an entire minute explaining why 9 plus 6 equals 15.

“Our young learners might not be all together comfortable thinking about what 9 plus 6 is. They are quite comfortable thinking about their friend 10,” the teacher says in the video. “10 is emphasized in our young grades as we are working in a base-10 system. So if we can partner 9 to a number and anchor 10, we can help our students see what 9 plus 6 is.”

She continues: “So, we are going to decompose our 6 and we know 6 is made up of parts. One of its parts is a 1 and the other part is a 5. We are now going to anchor our 9 to a 1, allowing our students to anchor to that 10. Now our students are seeing that we have 10 plus 5. Having them now more comfort seeing that 10 plus 5 is 15. That is much more comfortable than looking at 9 plus 6, an isolated math fact.”

Got all that?

Essentially, the Common Core way of solving the simple math problems has students decipher that 5 plus 1 equals 6 and 10 minus 1 equals 9 before they even solve the actual problem. One has to wonder why kids can’t simply be taught that 9 plus 6 equals 15.
