How to sort out math mistakes in primary schools
Karl, a famous educator

One of Witt's educational secrets,

Is to be tolerant,

Look at children rationally.

Cut, including "error". Wei Shusheng, a special teacher, set an example for us. He often goes out to sleep.

In the demonstration class, I often tell those strange students:

"Miss Wei likes to put my foot in my mouth in class. I guess

Students' psychological state and mood at this time.

How to collect wrong questions?

Because we have to find out the wrong questions,

So I will tirelessly look for it.

We know this is not a time.

This can be done overnight,

It must go through a long process,

So students must insist,

If you give up halfway,

Then all the previous efforts will be wasted.

You can insist on recording the wrong questions you encounter every day.

Insist on once a week.

Learn to communicate, analyze, communicate and supplement,

It is required to stick to the wrong questions and study until primary school graduates.

Until it continues to students' college studies.

Study, even life.

Students can follow the knowledge points of the review content,

Step by step, orderly classification.

For each knowledge point,

Further progress

Classification of common errors in rows.

Re-extract each wrong question,

Then create an error handling statement,

Error cause point

Analyze and summarize the types of mistakes, and finally write the correct problem-solving process. If there are multiple methods, they should also be formulated. I

Second, sort out the wrong questions and standardize the problem book.

Sorting out the wrong questions means sorting out the learning resources.

But the key is to find a sustainable and effective method.

And cultivate

Good habit. Sorting out the wrong questions is not the purpose, nor can it be sorted out in order to complete this task. Generally speaking,

Children need to organize themselves and form good habits by themselves.

To sort out the wrong questions, you should prepare books and number them according to the topic and time. Get your notebook ready.

In the future,

It is necessary to copy down the wrong questions one by one.

Write down the questions first,

Then why did you do something wrong?

The real reason is written in red,

Finally, write the correct answers and steps clearly.

The requirement is the same day.

The mistakes are sorted out on the same day, summarized once a week, completed once a month, and summarized once before the final exam.

day by day

First of all, after finishing your homework every night,

Take the wrong book,

Sort out the wrong questions collected today

And planning: put an "X" in the current topic of "fully understanding and ensuring not to make mistakes in the future" and an "X" in "incomplete"

At present, the question "I know I may make mistakes in the future" is marked with "○", while "I don't know why" has not made any mistakes.

The question "understand" is currently used "?" Mark.

Week after week

First of all, I tried to solve and understand the "○" level problem summarized every week, but I couldn't.

Can't solve it by yourself,

Be sure to ask the teacher for help and ask other students for help.

Anyway, until you understand.

The title of the checkpoint has been copied down again.

If you can't solve it yourself,

Upgrade it to

"☆"

Horizontal topic,

If you already feel that you can "eliminate", you will be downgraded to "○" and try to put it in the summary next month.

It was "destroyed" and downgraded to "X"

Every month.

First of all, sort out "☆ ☆ ☆ ☆ ☆ ☆ and"

Extinguish ",and then put" at the end of the week and in the middle of the month "

"Grade" and "χ", whether there is "elimination"

Extinction ",not only think about all this from the beginning, but also think about how you" destroyed "it at that time, and

Do these questions again with draft paper.

Finally, copy the results of one semester to another.

"wrong

"Fine topic", a copy of "Fine wrong topic" every semester. If this method is cultivated, review it.

It will become very easy, except reading textbooks and connecting with basic knowledge, that is, looking at the "mistakes" sorted out by yourself.

If such a good method can be popularized all the time, learning samples will be very simple.

Third, analyze the wrong questions and deeply analyze them.

(1) Students analyze, find out the reasons and correct their mistakes better.

Perceptual error

The numbers in the title are wrong or copied incorrectly.

Students are limited by the degree of thinking development,

It is easy to cause observation.

In the topic, the perception is vague, the attention is not concentrated, the observation is not careful, and it is easy to copy the wrong numbers and symbols. Such as some research.

What percentage, increase, increase to, how many kilograms have you made, how much have you saved, average and so on. Are there any students?

Have accurate understanding and mastery.

Sometimes after students correctly understand and remember the meaning of the question,

In the process of solving the problem

But I forgot part of the meaning of the question.

Or add new conditions,

Or distorted the meaning of the question,

This is also a digression.
