# More Common Core math foolishness One of the most critical resources in educating our children is classroom instructional time when the student is focused. In math, it is being focused on how to properly execute solving the problem—what solution method to use that solves the problem with a minimal waste of time and how to check the answer to see if it is correct.

Here is an example of third grade common core math where being different, confusing, and frustrating appears to be the primary objective of this homework assignment.

The problem is one of subtraction: 325 – 38 = ??? We were taught to solve this by borrowing and carrying numbers. This process works quickly for all subtraction problems.

In the Common Core solution being taught in the example, it takes six steps, including one not shown in the example, to arrive at an answer. Can you imagine someone trying to actually work a problem this way? Of the five steps, note that the work associated with the necessary sum of numbers at the end is not shown. Even the text book didn’t get it right.
