Let's get started:
Who chose D without hesitation? Please go to the outside of the classroom ~ ~
The correct answer is a. Why? Purchase at original price, sell at original price. Boss, are you doing well in this business ~ ~
Parents who exposed this problem said in their official WeChat account that the standard of a good question should be "impartial and not difficult to make mistakes". He put it this way: in primary school students' mathematics learning, most of them are pseudo-application problems. At the same time, the crazy swimming pool manager who injects water and discharges water, the two brothers who have been moving in a straight line at a constant speed, and the gardener who grows trees into obsessive-compulsive disorder … In real life, you can't find the corresponding projectile. But this question is different. It's not 3600 divided by 9, but it also has a simple life truth: in business, you always have to make a profit-but most third-grade children don't understand. This parent's article triggered a debate among netizens, and some people questioned the authenticity of the test questions. In this regard, the reporter learned from many parents that this multiple-choice question did appear on the final examination paper of the third-grade mathematics subject in Minhang District, Shanghai, and many primary school students also fell into the "trap" on this question. Parents disagree. I quite agree with some parents that this topic of "different painting styles" combines reality well, and teaches children the concept of "profit" while examining students' math exams. This kind of attempt should be encouraged. However, there are also parents who vomit. In real life, the market price of a violin with a cost of 100 yuan is at least several thousand or even tens of thousands. In real life, this problem is not "applied" enough. Objection In addition, some parents are worried that it is debatable whether this kind of examination questions inadvertently introduce consumption atmosphere into the campus. Parents who share this test clearly think that this kind of application problem is in line with educational logic and raise it to the discussion of commercial value.
What I want to say is that simple children can't do this kind of problem. Is it really good to guide children like this from an early age?
