What should I do if I can t understand the math application questions in junior high school?

Hello, the junior high school application questions are mainly to practice the knowledge you have learned to apply it in practice.

First of all, carefully review the question, grasp the main points and key points, and figure out the intention of the questioner.

1. The topic is very long, the key information of the handsome selection, the known information, the useless information, the hidden information, the routine information, and the information sought.

2. Analyze the known information, the relationship between the known information and the information sought, the correlation, recall the knowledge points you have learned, those that can be applied to this question, and how to apply them.

3. Problem solving ideas, using known information, plus the knowledge learned, can calculate those conclusions, how to combine these conclusions with the appeal problem or equivalent to the information sought.

4. Complete the problem solving and check the calculation. Substitute the calculation, or reverse the calculation, and continue to solve the problem below after the calculation is correct.

If it is difficult to review the question, then read the question carefully and think about it to know what the problem is.

Solve difficult problems, value information, and think about how to combine with what you have learned.

Difficulty in calculation, familiarize yourself with the key points of knowledge, pay attention to calculation methods, and practice more.

The above is the basic idea and logic of solving the problem, I hope it will be helpful to you. Hope.

1.Mastering the basics is to the point where you look at the questions and then think about what you're testing.

2.Practice more, you can look at the answers, but to figure it out, read more questions, and know what test points these questions have.

3.It is very useful to ask the teacher, and the classmates**.

Think more, don't give up when you encounter a problem, don't ask others easily, be sure to think, thinking is very important, when you stare at a topic for too long, you need to relax and then continue.

Glad for your question. First of all, don't be in a hurry. You can see if you have mastered textbook knowledge, textbook knowledge is the foundation, you must understand everything; Then you can do a lot of questions, record the wrong questions in the notebook, and check them repeatedly.

If you can't understand the math application problems in junior high school, the main reason is that you don't understand the meaning of the questions, so you can let your children do more types of questions to understand the good questions.

No. 1: Tap your potential. No matter what your situation is, you have to believe that you still have great potential.

There are many people who have improved by 50 places in the college entrance examination from now on, and it is possible that they have improved by 80 places. Plan 2: Firm will.

The college entrance examination is actually to see who persists to the end

Review: clarify the meaning of the question and the known and unknown numbers in the question; 2. Find the equivalent relationship: find the one (or several) equality relationship that can represent the full meaning of the application problem;

What to do, everyone has already seen it, do you really want to run out? At this time, you can see how your boyfriend reacts to this situation? Then you take it yourself.

Explain that the basic knowledge is not firmly grasped, and find a way to fill in the foundation later.

I think we should choose a tutoring organization to start from the basics and make our math better.

Find out the quantity relationship and the equiquantity relationship in the problem, according to the equation of the equiquantity relationship, you can also use the diagram method to find the equiquantity relationship.

The exam is approaching, and it is recommended to classify the practice type questions.

Sales, grasp the formula: selling price - cost = cost x profit margin Generally the cost is x. Then, the quantities that are known and expressed by x are substituted into the formula to obtain the equation.

Sum difference multiplier problem: Set the multiple sentence to x by the quantity before "of", then you can express each quantity, and then use another sentence with an equal relationship, that is, about the sum or difference of two quantities, to list the equation.

Itinerary problem: Remember: The problem of two places meeting in opposite directions at the same time: speed and x time = distance traveled. If it is not at the same time, then remove the time to go first and become simultaneous; If it is not an encounter, then remove the distance of the distance; Make not meeting an encounter.

Chase problem: The difference between the positions of the two cars at the beginning of the chase is the chase distance, then use: speed difference x time = chase distance.

You have to practice a few specific types of questions, and you are familiar with those routines!

First understand the book, and then figure out the example questions, get familiar, draw inferences, do the questions, if you really can't find this answer to study the answer clearly, these are self-study, you can also ask the teacher, you won't ask, hold the teacher, hehe.

If you don't know how to do it, ask more teachers or classmates, do more practice questions after class, think positively, understand deeply, and learn to draw inferences. Look at the sample questions in the books, they are very typical questions.

Do more questions and think more, go deeper from the simplest little by little, and get the unknown from the known conditions!

The most important thing is to practice more, and if you can't, ask your teachers or classmates more.

Read the question first, solve the equation and solve it! If there's anything you can't do, ask me!

Follow-up: But I can't read the question.

Follow-up: What to do?

Follow-up answer: Review the question first, read the meaning of the question carefully, and not be impetuous. Just list the relationships.

Follow-up: Uh-huh.

You understand word by word, analyze a variety of possibilities, read more questions, read repeatedly, think repeatedly, have good comprehension and association and imagination (understand by yourself, not all questions need Oh, generally more than the problem with the picture), if you really don't know, ask the teacher or parents and classmates.

Personal understanding, immature opinions.

1. Make a practical plan, and reasonably list the time period and goals to be achieved to complete the preview, study, and review of certain important knowledge.

Second, in the process of learning mathematics, it is necessary to have a clear sense of review, and gradually develop good review habits, so as to gradually learn to learn. Math revision is a reflective learning process. Reflect on whether the knowledge and skills learned are up to the level required by the curriculum; It is necessary to reflect on what mathematical ideas and methods are involved in learning, how these mathematical ideas and methods are used, and what are the characteristics of the application process; It is necessary to reflect on the basic problems (including basic graphics, images, etc.), whether the typical problems have really been understood, and what problems can be boiled down to basic problems; It is necessary to reflect on mistakes, find out the causes of mistakes, and formulate corrective measures.

Three mathematics is not equal to doing problems, do not ignore the most basic concepts, axioms, theorems and formulas, you can use holidays, winter vacation or summer vacation, to sort out the concepts in the textbooks that have been learned, through reading, copying and deepening the impression, especially the concepts that are easy to confuse should be thoroughly clarified, leaving no hidden dangers.

Fourth, mathematics needs to be practiced and needs to do a lot of problems, but it is necessary to "bury your head in the problem, raise your head and think about the problem", pay attention to the ideas, methods, and skills in the problem, pay attention to the internal connection between the problems, and "do it hard" but also "skillfully", and never "do it stupidly". When doing a similar topic to the previous one, it is necessary to discover the law and penetrate the essence through comparison, so as to achieve the realm of "touching the bypass". In addition, you should record the wrong questions in time when you usually do the questions, and think about why you make mistakes and what you should pay special attention to in the future, so as to avoid unnecessary loss of points.

If your weak links are involved in the test questions, you must pass a short period of special study, concentrate superior forces, overcome difficulties, and don't leave traps.

Memorize some question types and basic formulas first, and you will understand them later.

1.Lack of practice. There is a lot of life in life.

I haven't been in contact with anything before, and it's common for exercises or exams to be used to do dao cases and not be able to understand them.

A2Reading is small and comprehension skills are weak.

3.Not attentive enough. In the process of reviewing the questions, you need to be patient and careful to figure out the information provided in each sentence, and you can't look at it at a glance.

4.Not enough practice. Many students and parents are not interested in the sea of questions, but they have to admit that it is indeed effective.

There may also be institutional reasons, so I won't say much about it.

The first year of junior high school is okay, re-fill the foundation, and the foundation is solid.

The first floor is to be studied...

ef=4/5be

In ABM vs. EBF, EFB= AMB=90°

b is a public corner.

abm ∽ ebf

ef/be=am/ab=4/5

bf/be=bm/am=3/5

In ABM and ECG, CEG = BEF = BAM

egc=∠efb=∠amb=90°

abm ∽ ecg

ge/ec=ma/ab=4/5

gc/ce=mb/ba=3/5

Let the perimeter of BEF be a, and the perimeter of CEG be b, then a+b=ef+bf+be+ge+gc+ec=4 5be+3 5be+be+4 5ce+3 5ce+ce=12 5bc

The relationship between the perimeters of 24 bef and ceg is that the sum of the perimeters of the two triangles is a fixed value of 24

In bef and bam, the two triangles are similar because they are two right angles, and the angle b is a common angle, ab be=am ef

5/be=4/ef,ef=4/5be

bf bm = ab be, bm = root number (ab 2-am 2) = root number (5 2-4 2) = 3, bf = 3 5be

DG AB, angular BFE=90, so angular EGC=90, triangular BFE is similar to triangular CEG.

and bf=3 5BE, so CG=3 5CE, the same way ge=4 5ec (corresponding to the edge establishment ratio).

This is equivalent to the financial compound interest formula, using x square = 15%, which is not right, you may be close to a little bit with 2x = 15%.

It can be understood in this way, you have 100 yuan in the bank, and the interest is paid every year, and after two years, there is a total of 115 yuan, so 15 yuan of interest is paid. Ask what the interest rate is, it is the same, let the interest rate be x, then the first year has 100 * (1 + x) yuan, and the second year has 100 * (1 + x) square (yuan).
