True enough, but the problem comes when the tests are aligned to the CC and the student is asked to solve the problem the CC way (and show their work).  If the student does not show his work the way CC wants it done, he loses points.  So the teacher is definitely forced to teach the CC method.  Of course the teacher can add other methods, but the student has to have enough practice with the CC method in order to pass the mandated test (and they are still mandated).[/quote]

What way is the Common Core "method" or "way", please?

CCSS.Math.Content.2.NBT.B.6
Add up to four two-digit numbers using strategies based on place value and properties of operations.

CCSS.Math.Content.2.NBT.B.7
