Common Core Math is Ridiculous

Quick! What’s 15-7?

While obviously the answer is eight, new Common Core textbooks have a rather confusing way of getting there. According to the textbook, students should employ “subtraction sequences” based off of 10 in order to find the answer.

While C is the correct answer, it is confusing why the textbook is making something relatively simple into something far more challenging.

Common Core is a new set of education standards that have been adopted by most states.

Addition is given the same treatment as subtraction: apparently in Common Core land, numbers after 10 do not matter.

Other Common Core math questions are just plain confusing. Take for instance this sample question from a New York State exam for third graders:

There were 54 apples set aside as a snack for 3 classes of students. The teachers divided up the apples and placed equal amounts on 9 separate trays. If each of the 3 classes received the same number of trays, how many apples did each class get?

A) 2


B) 6

C) 18

D) 27

While the answer is C, I fail to comprehend why the second sentence was added to the problem. The problem is asking, in plain, non-apple terms, 54 divided by three. There was no reason to mention nine trays, or equal amounts of apples on each tray. The question is designed to frustrate and confuse third graders, and this cannot be helpful in the long run. Do we want our third graders to hate math?

Meanwhile, the United States continues to lag in math competency.

While math was never really my strongest subject, I had a pretty strong grasp on basic addition, subtraction, multiplication, and division. Now I’m thanking my lucky stars that I learned math in the pre-Common Core era.

    Yes this problem is ridiculous for a 3rd grader but there is no unnecessary information in the problem. You could only solve the problem the way you are thinking about it if you knew that all three classes had the same number of students. Since that was never stated, you need the information in the middle to confirm that assumption and then allow the problem to be solved. Otherwise, who’s to say two classes didn’t have twenty students while one only had 14 and/or that the trays didn’t contain different numbers of apples. Then the problem would be unsolvable.
