For a first-grade math problem, parents and teachers quarreled, netizens: it seems to make sense
It is said that today's primary school students are not easy, not only do they have a lot of homework, but also the angles of some topics are particularly tricky, and there are many difficult and strange problems. Recently, a math question for a first-grade primary school student in Hangzhou became popular.
The topic is this: Xiaotian is 10 years old this year, and his elder brother is much older than him. How old might his elder brother be? There are four answer options: 60; 18; 12; 9. The primary school student chose 60 years old, but the teacher gave the wrong judgment. It is said that the correct answer should be 18 years old.
The primary school student's parents are both university teachers, but they can't understand why this question has to be 18 years old, but not 60 years old or 12 years old. It stands to reason that 60 years old is much older than 10 years old! What's wrong with this?
Later, I asked the teacher, and the teacher gave an explanation: there is a key piece of information in the question stem. The question is about the age of my brother. Since Xiaotian is 10 years old, it would be too unreasonable for his brother to be 60 years old. And if my brother is 18 years old, such an age difference is closer to reality. In addition, if you choose 12 years old, you will not meet the requirements of the much larger title. So, the correct answer to this question is 18 years old.
The teacher said that this question not only examines the students' understanding of the concept of being much bigger, but also examines everyone's understanding of the elder brother. It is a question that combines real life.
However, many parents did not seem to buy the teacher's explanation, and they also raised different opinions.
Some parents think that the subject mainly examines the concept of being much bigger, and it seems a bit too demanding to ask first-year students to think from a physiological point of view.
Some parents said that the case where the elder brother is 50 years older than the younger brother is not non-existent. There were many such examples in ancient times, so from this perspective, it should not be wrong for a child to choose 60 years old. Besides, children's thinking is generally more one-way. When they see three words that are much bigger, they will naturally choose to be 60 years old.
Some parents think that in the concept of children, he does not actually think that a brother must not be 60 years old. Now many children like to call them elder brothers when they meet strangers who are older than themselves. This is also a social appellation. Variety.
Some parents even said that even if the child chooses to be 60 years old, he does not think the child is wrong, but encourages the child to think and question by himself.
Unexpectedly, a math problem in the first grade of elementary school has aroused such a big response from everyone.
However, in my opinion, the author of this topic still agrees with the teacher's explanation. Just like many children, when they heard the teacher ask how old their brother should be, they immediately realized that 60 years old should be the age of their grandfather.
Finally, I would like to ask everyone, what do you think about this issue?
