A second grader’s answers to a Common Core-aligned math worksheet were marked as incorrect because they weren’t “friendly” enough… even though they were the right answers.

A screenshot of the worksheet was posted to Twitter. The teacher wrote that even though the questions — addition and subtraction problems — were solved correctly, the student used the wrong technique to arrive at the answers.
“Correct answers, but let’s find the ‘friendly’ numbers,” wrote the teacher.
The teacher wanted the student to solve “530 – 270 = ?” in the following manner: First, add 30 to both numbers, changing the problem to “560 – 300 = ?”. These numbers are the “friendly” numbers, because they are supposedly easier to work with.
The student, however, simply subtracted 270 from 530 the good old-fashioned way, arriving at the same answer. Unfortunately, this is not a Common Core-approved technique.
