What should I do if math is getting harder and harder in Grade Two?
The difficulty of mathematics subjects changes obviously, and the knowledge related to geometry is easy to understand, such as the definition and judgment theorem of geometry.
? However, in the examination, a problem often involves the examination of multiple test sites, which increases the difficulty of the examination, the gap between students begins to widen, and some students begin to show partiality.
Partial subjects are an important factor affecting the total score of the senior high school entrance examination, so we should try our best to avoid the problem of partial subjects in the second grade, allocate more time to weak subjects, and find efficient learning methods at the same time.
What problems should be paid attention to in order to adapt to the mathematics learning in the second stage of junior high school?
1
Avoid falling into the misunderstanding of mathematics learning
In the process of junior high school mathematics learning, some students' mathematics learning methods are incorrect and easy to fall into the misunderstanding of methods. They spend more time and energy on math learning, but the learning effect is not obvious.
If you want to make a breakthrough in mathematics learning, you must first change your learning methods.
For example, some students think that if you understand the content in class, you will learn the relevant knowledge points, and you will be able to make corresponding knowledge points in the exam.
But a question in the exam will involve the examination of multiple knowledge points. Without practice, knowledge cannot be linked.
In addition, some students think that learning math well needs to brush more questions.
Learning mathematics well requires strengthening practice in the process of learning and skillfully using knowledge points by doing problems, but learning mathematics well does not mean brushing problems blindly, which will cause a waste of time.
Because in the process of brushing the questions, you will encounter repeated questions, but because you have not mastered the ideas and methods of doing these questions, you will still not solve similar problems.

Follow the law of mathematics learning
In the learning process of junior high school mathematics, we should follow the learning rules of mathematics, and the learning time can be shortened, but we can't cross the learning stage.
In mathematics learning, we must first master the basic knowledge points in textbooks, such as congruent triangles's judgment theorem and the nature of special triangles, which are the basic basis for doing problems.
When you do the problem, you will make changes on the basis of basic knowledge. A knowledge point will correspond to multiple problem-solving methods, and you need to master it through practice.
In addition, the focus of mathematics learning is to grasp the thinking mode behind doing problems through the method of summarizing questions, and know where to cut in when encountering different questions.
three
Develop good study habits
To learn junior high school mathematics well, we must develop good study habits. If the habit of learning mathematics is not cultivated in the first stage, it is necessary to gradually cultivate the habit of learning mathematics from the second stage.
Students need to get into the habit of sorting out wrong problem sets.
It should be noted that in the process of sorting out the wrong questions, it is one thing to sort out the wrong questions in the wrong question set. What is more important is to review the wrong questions regularly and master the correct methods and ideas for doing the questions.
In addition, in order to improve the efficiency of learning mathematics, we should be good at using external forces, ask teachers or classmates for advice in time for questions we don't understand, and learn from and master more efficient methods of doing problems.
Skills of wrong problem set in mathematics
Learning is divided into two steps:
1
Find it. number
This step is simple. Of course, we can find many problems when we brush the questions, and generally record the problems that we can't according to the source.
2
Turn what won't into what will.
The second step is the wrong problem set, which is the essence of learning. During the review period, a lot of time should be spent misreading the problem book repeatedly.
Mathematics is the epitome of scientific thinking. Just remembering formula theorems can only be broken by drawing pictures. Many problems are buried everywhere, so we must pay attention to them.
What's more, mathematics questions are ever-changing, and the methods and combinations of solving problems are also very different.
There is a perfect wrong problem book, which is very valuable for the research and reflection of wrong problems in mathematics.
The method of doing the wrong problem set can refer to your own preferences. It doesn't matter if you like copying questions or not cutting books. It is important to know how to use the wrong problem set.
How to do the wrong problem set?
0 1
think
The train of thought mentioned here refers to all your ideological activities when solving this problem, including your analysis of the subject conditions, preliminary ideas, derivation process and so on.
In particular, the stuck and wrong parts should be recorded in detail. It is strongly recommended that you don't ignore the calculation errors.
A classmate didn't find out the reason why he always lost points in his calculation problems until shortly before the college entrance examination: he always divided 1 by 2 to calculate 2! How terrible it would be if this mistake continued to the college entrance examination!
02
Various solutions to a problem
The standard answer given by the question answer must be copied down, which is the most basic requirement.
It is also the least that students who have a bad start should do; If the foundation is good, then try to get as many ideas as possible every time you make a mistake.
The reason for doing this is to improve the thinking ability on the one hand, and to meet the requirements of the exam on the other hand.
What the students who strive for perfection should do is to draw inferences, that is, to find other 1~3 questions with similar questions or ideas to this wrong question.
I will use my experience and skills in studying the wrong questions to verify the new ones.
03
Multi-review summary
After recording the above two contents, there must be a summary section at the end, which concisely expresses the shortcomings of your thinking ability and the questioner's requirements, which links are not well done, and the experience and skills you have gained from this series of right and wrong research.

Answers to several common questions:
Some students may ask: what's the use of working hard if you don't take care of it?
In fact, if you can really use the above steps to study a wrong question, then you don't have to worry that you will forget the idea of this question, so it doesn't matter whether you look at it or not;
To say the least, even if you finally forget or don't do it seriously, you can still read the reflection part of the wrong question from time to time, and the effect is just as good.
Attention! Don't make these mistakes!
1, don't do the wrong problem set.
The wrong thing is always wrong, and it will be wrong as soon as the final exam is done.
2. The wrong problem set can only be read before the exam.
This doesn't understand why you use the wrong set of questions! Some people will spend a month brushing the questions you already know, but never try to understand them. So what are you studying? Brush grades?
3. The wrong problem set only increases.
