Doing math is always afraid of making mistakes.

How important is the draft?
Making a draft can ensure the correctness of the calculation process and results as much as possible. Especially for problems involving a lot of calculations, it is particularly important to draft. For example, after the fifth grade of primary school, it is easy to make mistakes if you only do math problems by oral calculation.
Many children don't like to draft for two main reasons. One is that they didn't realize the importance of drafting, so they didn't get into the habit. The second is that I think it is a waste of time to draft, and I want to leave the time for drafting to do more problems. As a result, I made mistakes every time. Many wrong questions were not difficult, not impossible, but miscalculated.
Therefore, it is very important to make a draft. Of course, if the time is really too late for the exam, you can flexibly decide whether to make a draft.

Problems in student drafting
Although most children can draft, they can't draft correctly. What do you mean? For many children, making a draft is nothing more than deducing, calculating and copying the results into the test paper. But few children will use the draft book in a standardized way, and the draft book is in a mess. Often because some writing is not standardized, the answer is copied wrong!

No matter which angle you switch to, you can find traces of the draft. To put it mildly, it's a mess. When you look back, you can't find the direction and focus. It is easy to make mistakes when copying answers and checking grades, and recalculation is also a waste of time.
Because of this, many students had some ideas when calculating on the draft in the examination of mathematics and physics, but when they went back to do the questions on the test paper, they were confused because the draft was too messy and did not form clear logic and ideas.
Look right, not only writing norms, but also clear steps and title numbers. This method generally does not make mistakes when copying the problem-solving process and the final check. Once there is a calculation error, it is easy to find out where the problem lies and remedy it in time.
Those children with excellent grades usually attach great importance to standardized draft calculus, which helps them to straighten out their own ideas and reduce unnecessary mistakes. Accordingly, they are more organized than other students in other aspects of their studies, which is why they get good grades!

What should a good draft look like?
1, writing should be standardized and orderly, and writing should be as serious as homework, not sloppy, otherwise it will bring many unnecessary mistakes.
Write a row of numbers one by one, don't write two rows of numbers together. Don't write too full, but make the layout of the draft paper clear, because some students "save too much" when making drafts and use the draft book at will, resulting in the whole draft paper being full and looking big.
3. Drawing should still be used as a drawing tool, but it should be faster and not perfect, but it can't affect solving problems. After all, exam time is precious.
4. In the process of examination, if you encounter any questions that you are not sure about, you should indicate the inspection link, which makes it easier to find out and fill in the gaps.
5. There should be partitions or dividing lines on the draft paper. Sometimes the draft contents of the two questions are too close, so it is necessary to separate the draft contents between the two questions with a dividing line to avoid copying the process of question A to the answer area of question B when answering questions on the test paper.
6. Mark the book name. Whether doing math homework at ordinary times or taking a formal exam, you should mark the title number on the draft paper, and locate the position on the draft paper by the title number, which is clear at a glance and convenient for quick search.
7. Draft in sequence. Some students like to pick blank places when making drafts, so that there are drafts in all directions, so that as long as there is no "draft" in the grass, they will not find it after a while. Such a draft is absolutely impossible in the exam.
8. The calculation steps, outlines and ideas are basically complete, and the process is generally standardized. Why do you say "basic" and "general"? Because this is the role of the draft. After making mistakes for a while, I still can't find the problem, and I can't find it. An incomplete draft is almost equivalent to nothing; There is no need to go into too much detail.

The draft is scribbled!
Excellent draft is valuable learning wealth, full of students' thinking traces of analyzing and solving problems, which not only greatly improves students' learning efficiency, but also effectively improves students' academic performance.
Let the draft not be "grass" and turn "grass" into treasure, which is the cornerstone of every student's performance improvement and an effective way to cultivate children's clear logical thinking.
How to Improve Math Answering Skills in Senior High School Entrance Examination
1, find out the "topic" quickly.
When you get the test paper for the first time, you will feel nervous. Don't rush to answer in this state of tension. First, we should browse the whole volume from beginning to end, from front to back, and get as much information as possible from the surface of the volume. The principles of finding out the "topic situation" are: easily answer simple multiple-choice questions or fill-in-the-blank questions that can be seen at a glance; Questions that cannot be answered immediately can be divided into two categories: familiar and unfamiliar. Mastering this information will ensure that there will be no embarrassing situation that "the difficult problems in front will not be done, and the easy problems behind will not have time to do".
2. The order of answers is "the first three and the last three".
After browsing the examination paper and answering simple questions for the first time, our mood should be much more stable and we will be full of confidence in ourselves now. We should understand that it is not easy to get most marks in math subjects, so we should allow ourselves to lose some marks. You should follow the principle of "three first and three later" when doing the questions.
The first is "easy first, then difficult". It's easy to understand. Do simple questions first, and then do complex questions. When all the questions are finished, if there is still time, come back to study those difficult problems. Of course, this does not mean that when you are doing a problem, you will jump over it when you encounter a little problem, which will leave too many problems for yourself. This goes against our original intention.
Followed by "high first and then low". This mainly means that if there is not enough time, we should do the questions with high scores first and then the questions with low scores. In this way, you can get more total scores. Moreover, high-scoring questions are generally graded in sections, and the first question or the second question is generally not particularly difficult, so try to make these two questions. Generally speaking, this will be more cost-effective than taking out the corresponding time to do a low-scoring topic.
Finally, it is "first the same and then the different". When I say "same before different", I actually mean that under the condition that the general order remains unchanged, we can distinguish difficult problems according to the major categories of topics and consider the same types of topics together, because the knowledge points used in these topics are relatively concentrated, and it is easy to improve the efficiency of unit time when thinking.
3. The principle of "one is fast and one is slow".
The so-called "one fast and one slow" here means that the questions are slowly examined and the questions are quickly done. The topic itself is actually all the information sources of this topic, so when examining the topic, we must read it word by word, and strive to truly see the meaning of the topic from grammatical structure, logical relationship, mathematical significance and other aspects. Some conditions don't seem to be given. In fact, after careful investigation, you will find that you can collect more known information and seek protection for the correct rate of doing the questions. When thinking about the methods and ideas of solving problems, the answers must be concise, fast and standardized. This will not only win time for the following questions, but also simplify the problem-solving steps as much as possible on the basis of ensuring that you step on the scoring point, so that the marking teacher can see your problem-solving steps more clearly.
4. Master the skill of "grading by sections".
For the math problems in the senior high school entrance examination, it doesn't mean that only students with excellent grades score, and other students don't score. In fact, the strategy of "grading by sections" is adopted in the big math questions of the senior high school entrance examination. Simply put, if you do the right step, you will be given a step. This ensures that you don't lose points on the topics you can do and strive for more points on some topics you understand.
5. Check and highlight the key point "Ensure score".
