Missing the point often happens when deference to the correct authority is ignored. Frequently, doubts have already been planted in someone's mind so the one's task is simply to discredit. With this agenda, we really cannot see even if we look. This also happens in education when we do not respect the teachers, the individuals with whom we have entrusted our children. It is necessary that we see teachers as the educators of our children. Otherwise, we will become completely blind.

There was a parent's rant against the Common Core that went viral on

The above homework was asking the student to write a letter to Jack. Jack was apparently trying to solve the arithmetic problem, 427 - 316 = ?, using the number line. On top of the homework is Jack's drawing of the number line:

I had to clean up the previous picture so that the question is clearer. Jack in the above picture was basically subtracting only 306 from 427. This was the reason why Jack arrived at the answer of 121. This was basically the homework question. It was plainly asking us to review what Jack did. Jack knew decimal places. The 3 in 316 is three hundreds and the 6 is plain 6 ones. What Jack forgot was the 1 in the middle of 316, which was in the tens' place. This homework had nothing to do with teaching students a specific way of subtracting two numbers. This homework was meant to be an activity for a child to review another person's work. Yet, the father who posted the rant became an instant hit on social media.

Dear Jack,

Don’t feel bad. I have a Bachelor of Science degree in Electrical Engineering, which included extensive study in differential equations and other higher math applications. Even I cannot explain the Common Core mathematics approach, nor get the answer correct. In the real world, simplification is valued over complication.

Therefore:

427 – 316: 111

The answer is solved in under 5 seconds – 111. The process used is ridiculous and would result in termination if used.

Sincerely,

Frustrated Parent

Someone who has studied differential equations and other higher math applications should have developed reading comprehension as well. This parent totally missed the point of this homework. It was not trying to force a specific method of subtraction. It was an opportunity for a student to review someone else's work. Yet, not only did this dad miss the important point, but so did the thousands who have liked and shared the above misguided rant.
