When it comes to brain teasers, I believe most mothers and fathers have played this kind of game with their children!

What is a brain teaser?

For example: I went fishing yesterday and caught a tailless fish, two headless fish, and three half-cut fish. How many fish do you think I caught in one day?

This is a brain teaser. Douma will tell you the answer at the end of the article. Please read the full article!

Speaking of which, there are great benefits for children to play brain teasers:

① Develop intelligence, and the more you use your brain, the more flexible it becomes!

②Activate brain cells and exercise the brain;

③Improve your imagination, after all, the brain teasers are very weird;

④Prevent Alzheimer’s disease , prepare for a rainy day!

⑤Brain teasers are fun and can liven up the atmosphere.

So, most children are not repelled by brain teasers and are even eager to try them! Moms and dads will also participate, which can also enhance parent-child bonding.

However, children’s brain teasers all appear in games. What will happen if it is placed in a math test paper?

There are 4 people in front of me and 6 people behind me. How many people are there in one ***? Points were deducted from the child’s “correct answers”

Dou’s mother saw such a case online.

Xiaohua’s daughter is a first-year student with excellent academic performance and an outgoing and cheerful personality. She is a typical “other people’s” child.

However, in the final exam before the epidemic in winter, Xiaohua’s daughter’s ranking in the class declined. She had always been in the top three before, but this time she fell to eighth. The problem mainly appeared in the math test paper.

Xiaohua’s daughter has always scored 100 points in her math test. No matter how bad she was, she never got lower than 98 points. But this time she scored 95 points and got a wrong question. This is very "hurtful". ".

If your daughter really doesn’t know how to do it, it doesn’t matter if she scores 95 points in the test. She can just correct it next time.

However, she didn’t know where she was wrong, and even Xiaohua couldn’t find out why she was wrong. So during the winter vacation, Xiaohua’s daughter asked the teacher for advice, and the teacher gave the answer It’s dumbfounding!

Original question: Peppa Pig asked: I am queuing up. There are 4 people in front of me and 6 people behind me. How many people are there in the queue?

Normal people’s algorithm is: 4 6 1=11. Is there any doubt about this? But the teacher made a big red cross and deducted 5 points directly.

“Look at the original question, Peppa Pig asked, how many people are in the team? Peppa Pig is a pig and cannot be counted as a human being, so excluding himself, it is 4 6 = 10 (human beings). ”

The answer given by the teacher was a bit unexpected, but it was reasonable. My daughter reluctantly accepted this statement.

However, Xiaohua was not happy and turned to the teacher directly:

"If you say so, the pigs will still line up? What kind of pig is this?"

"We are training children's thinking flexibility."

However, Xiaohua does not agree with the teacher's point of view. Mathematics is a rigorous subject. If the teacher randomly sets questions like this, it will destroy the children's logical thinking.

Leonardo Da Vinci once said a famous saying, "In science, any place where mathematics is not used, any place that has no connection with mathematics, is unreliable. Mathematics is the foundation of all sciences." "

Faced with Xiaohua's question, the teacher asked another question:

"There are 10 hens and 2 roosters on the farm. On average, each chicken lays 2 eggs every day. How many eggs can you lay in two days?"

This time, Xiaohua knew that this was also a brain teaser, so she didn't fall for it and answered directly, "40."

"Look, this can be considered a brainteaser, right? It's not imprecise at all.

"

The teacher's retort made Xiaohua even more angry, "Chickens are common animals. No matter how stupid a child is, he will know why roosters don't lay eggs. But what do you mean, Peppa Pig? ”

So, a heated debate began...

Should brain teasers be included in the mathematics test paper?

Opinion: Agree!

Some mothers think it is reasonable to put brain teasers into math papers.

First of all, this can exercise their children's thinking and reaction skills. Many mothers feel that exam-oriented education can cultivate them. Children in the United States are all "silly children". Children in the United States are more open-minded and have wild imaginations. They are best at this kind of interesting questions.

Moreover, even if this kind of questions can easily make children fall into the trap, It can be included in the additional questions, which will not affect the overall score and can exercise children's imagination.

Finally, the test paper is fair. Everyone has the same questions. Why can others answer the brain teasers correctly? Are you right? This shows that children are rigid in thinking and need to analyze and think frequently.

In the fifth season of "Love Apartment", Zhang Wei shared his experience in elementary school.

There is a math question: A person bought 60 watermelons and ate 40 in one go. How many are left?

Most students focused on the correct answer - 20. However, Zhang Wei asked Teacher Xiang: "Why did this person buy 60 watermelons? How did he eat 40 watermelons in one sitting? Is he okay after eating 40 watermelons? ”

Through Zhang Wei’s answer, we can see that he answered the question from a perceptual perspective, considering rationality and human touch.

If Zhang Wei answered Peppa Pig questions, you will definitely get the real correct answer.

To sum up, we agree that brain teasers should be added to the math test paper, and don’t let the children study hard!

Contrary opinion! : Disagree!

Mathematics is a rigorous subject that mainly exercises children’s logical thinking. If you want to stimulate children’s imagination and creativity, wouldn’t other subjects or games work? Peppa Pig queues up and the hen lays 2 eggs every day. Judging from the theme alone, it is not scientific, especially the former. It is easy for children to ignore that piglets are not considered "people".

This kind of story is not scientific. The question is just to make things difficult for the children, and it doesn’t have much practical significance!

If it is an intellectual game question, there is no problem with this kind of question, but if it is placed in a mathematics test paper, it is still a final exam question, and the person who wrote the question does not think it is wrong! Is it rigorous?

Can’t Peppa Pig be a person’s name? This person’s surname is Piggy, so isn’t this idea also reasonable?

To sum up, we disagree that brain teasers should be included in math papers.

How to cultivate children's imagination and creativity?

To put it bluntly, brain teasers are exercises. Children's imagination and divergent thinking are one way, but they are not unique.

If you really want to cultivate your children's imagination and creativity, you can do the following 3 things:

1. Graffiti

In the game "Chinese Parent", we can see that if children like to graffiti, their imagination points will increase.

Doodles are children's imagination. Through children's graffiti, we can see countless strange works, and these works are the result of children's release of imagination and creativity.

2. Writing

Most children have a dream of writing when they were young. After reading interesting extracurricular readings and online novels, interesting story scenes of galloping horses will appear in their minds.

Through words. Write down the scenes in your mind. This is the process of cultivating children's imagination and creativity.

3. Toy Games

The toys that children play when they are young all cultivate imagination and creativity.

Let’s take a puzzle as an example. A simple puzzle may only have dozens of pieces, while a difficult puzzle may have hundreds or thousands of pieces.

The process of children playing puzzles not only requires great patience and high concentration, but also uses their imagination and creativity to build up the prototype of the puzzle in their minds and constantly push it down. , Reproduction, this process is very important.

Similarly, the same is true for building blocks!

As for games, if you want to cultivate children's imagination and creativity, it must be "Minecraft"! I believe that all MC players will agree with this!

Message

According to the results of a survey of 21 countries around the world conducted by the International Assessment of Educational Progress, Chinese children rank first in the world in terms of numeracy, but ranked last in imagination. Creativity ranks fifth from the bottom.

It can be seen that it is urgent for us to cultivate children's imagination and creativity, but the way is not necessarily to add brain teasers to math problems, which has little effect and may cause dissatisfaction among children and parents.

After all, mathematics is an academic field, and we must be rigorous and serious, right? Dear mothers, do you think brain teasers should be added to the math test paper?
