When a child has a math problem, the teacher says that the calculation is wrong, but netizens say th

Children are right because they have their own thinking skills. It is not always possible to put yourself in a God's perspective to make a child perfect. They should be from the child's point of view.

This is because the child's mind is very jumpy, and the brain hole is also very big, and then netizens, if the child's perspective comes to the math problem, they find that the child is not wrong and does it right.

Summary. Maybe it's also a coincidence, because some things in life bring emotions to work. I suggest that you calm the child first, and then see if this is the case after a while. If you still have it, if not, please contact the teacher.

Dear, is it because the child didn't do much to correct the wrong questions, the teacher is angry?

Hello, my child is in the sixth grade this week, and there are two application questions in the four-unit exam last week, and I made a mistake and corrected the wrong questions to ask the teacher, and then this is it.

First of all, the relatives may explain that these two questions are still wrong, and the teacher may not have a good spleen and loose breath, and he was very angry when he saw that the child had not changed, and then he said this. Indeed, as a teacher, you should continue to talk to your child about what you did wrong. This teacher's attitude and temper are really bad.

The teacher is usually more kind, but after listening to the child, I was blinded.

Maybe it's also a coincidence, because some things in life have brought emotions to the Ministry of Industry. I suggest that you calm the child first, and then see if this is the case after a while. If there is any, if you don't have a family, you can pretend to be a bridge and contact the teacher.

There are many reasons for miscalculation of questions, the first of which may be that you are not careful enough. would have done it, carelessness, and the reason for this, the second is that you will not do ignorance. The first reason is that we should let the children be careful in their questions, and the second reason is that we should usually grasp it and ask more questions if we don't know how to ask.

It shows that such children are more careless, and parents should educate their children and make them more careful. It's better that way.

Generally, he will choose to let him memorize the 99 multiplication table, and use a calculator, and then ask him to do his own oral arithmetic, which can actually cultivate his mathematical ability, and the arithmetic will get better and better.

Your child fills in the process, and the teacher wants the result. Explain this to your child. The teacher is right, but he is not attentive enough.

On the other hand, sometimes the teacher reads too much homework, and it is inevitable that there will be mistakes.

Without this statement, it should have become the original 1 100

In mathematics teaching, we often find that children do problems when they do homework, but they don't necessarily get it right. Sometimes when I put the assignment to be corrected in front of the student, he immediately realizes that he is wrong, he will say "ah" and say, "How did I write it wrong".

It's either that a 0 is missing here, or that the answer is missing there. Some students always read the wrong numbers when doing questions, often writing 45 as 54, 18 as 81, and missing questions. Let's just say that in the three-digit addition we teach now, I found that students know what to pay attention to when doing pen calculations, and when you ask him, he will tell you out loud how it is, but in the real calculation process, there is either a lack of carry or a wrong answer, and few people can complete the homework seriously and carefully.

Some students can't complete the homework once or twice, you tell him which question has not been carried in place, and he will correct the question and hand it in, without thinking about the other questions and forgetting to carry the position, so it takes several times to run back and forth before the correction is completed.

I think when parents look at their children's homework or test papers, they will also find that the questions that the children would have done are wrong, and it is because of the child's carelessness. Some parents may think that their children are careless and cannot be changed. Actually, I think that carefulness is also a kind of ability, it is a kind of psychological quality, which can be consciously cultivated.

What do you mean? Correcting mistakes?

A lot of it is miscalculated, and the column formula is correct. For example, the second sheet to find the surface area of the cuboid in the middle 4x9=32, 88+55+40=143, etc., are all calculation errors

Careless, 54+27+18 miscalculated, it's very good that the child can calculate this step in this question, but he miscalculated this place carelessly, resulting in the final result being wrong.

The problem of painting the wall, the need to paint the wall is the four sides of the room, that is, (8 * 3 + 7 * 3) * 2 + 7 * 8 However, the question said that the area of doors and windows is 22 square meters, and the examination question is not clear, then 146-22 = 124 square meters, with 124 * kg of paint).

The five centimeters that rise is the volume of the fish: (5*80*50) 40=500 (cubic centimeters) This oral calculation can be calculated like this: 5*50*(80 40)=2*5*50=500

Three. 1 is also careless, 4*9=32, is 36 okay.

Three. 2. It's still a careless mistake. After counting 88 + 55 = 143, forget the 40 behind, it should be 143 + 40 = 183 and then 183 * 2 = 366

Summary: There is no problem with children's logic, that is, carelessness, more calculations, don't use calculators to do questions, it's really not good, just remember it after two more hits. These scores are avoidable.

Let the seed ** be x

2x+x= and then substitute 2x+, and the solution is 2*

A total of 150 yuan.

Find ** per kilogram first.

This question is wrong, and the answer is no solution.

Adding 1 to 8 equals 36, and in the question, 1+9+2+7=36-2a-2b=19

36-19=17, 17 is odd, so it's not possible.

The first question is equal to: 3 8 + 5 8 + 2 7 = 1 + 2 7 = 9 7

The second question is equal to: 25-(2 15+13 15)=25-1=24

The third question is equal to: 4 23 + 19 23 + (2 5 + 3 5) = 1 + 1 = 2

All three questions are wrong:

The first course: 3/8 + 2/7 + 5/8.

Three-eighths + five-eighths + two-sevenths.

1 + two-sevenths.

Seven out of seven + two out of seven.

Nine out of seven. Second way: 25 - 2/15 - 13/15.

25 - (2/15 + 13/15).

25 - fifteenths of a fifteenth.

24 The third way: four-thirds of twenty-thirds + two-fifths + nineteen of twenty-thirds + three-fifths = (four-thirds of twenty-thirds + nineteen of twenty-thirds) + (two-fifths + three-fifths) = twenty-three of twenty-three + five-fifths.

All wrong first question = (3 8 + 5 8) + 2 7 = 1 + 2 7 = 9 7

Question 2 = 25 - (2 15 + 13 15) = 25 - 1 = 24

Question 3 = (4 23 + 19 23) + (2 5 + 3 5) = 1 + 1 = 2

It's all wrong! This kid has to be in charge! To do these questions, first of all, add and subtract with the denominator, and then further calculate it is very simple, the answer given by your child is not even the basic algorithm, and the answer is confused! Different denominators should be converted into fractions with the same denominator!

The first error should be (3 8 + 5 8 + 2 7) = 1 + 2 7 = 1 and 2 7

The second error should be 25-(2 15+13 15)=25-1=24

The third one is also wrong, it should be (4 23 + 19 23) + (2 5 + 3 5) = 1 + 1 = 2

It's all wrong, I'm also drunk, the first question is nine out of seven, the second question is twenty-four, and the third question is two.

It's obviously messy. It is not possible to have a denominator with different multiples. There is no appointment.

Question 1 11 and 9/7 Question 24 Question 3 2

All three questions are wrong, and the method must be used correctly.

9/7 of the first answer 24 24 3rd answer 2

I won't type it either, so I'll send you **.

The first question is 8/23 wrong.
