IJR Review provides an example of the ludicrous Common Core math problems children are being subjected to.

A child (probably a first grader) is asked to make 10 by adding 8+5.  The child responds,

“You can not make 10 withe 8 + 5.”  (You can not make 10 with 8 + 5.)

The teacher writes back,

“Yes you can. Take 2 from 5 and add it to 8.   (8 + 2 = 10).  Then add 3.”

The teacher is performing a Common Core technique that involves “decomposing,” “partnering,” and “anchoring”.

It’s not necessary to comprehend these concepts because they have no practical use, but if you wish to, see HERE.
