Junior high school mathematics is the basic content of junior high school mathematics, with little content and not great difficulty. If I can spend more time on consolidating and reviewing mathematics during the holiday, it is entirely possible to keep up. When reviewing all the contents of senior one in summer vacation, we need to find the test sites and the key points and difficulties based on the senior high school entrance examination. Judging from the distribution of knowledge points in the senior high school entrance examination papers in various provinces and cities, the content of senior one accounts for about 20-30 points in the whole senior high school entrance examination mathematics paper (the full score is 120). Different provinces, cities and textbook versions will be slightly different, but the content of senior one will be directly examined in the senior high school entrance examination, and they are all very basic topics.
Let's take a look at what we have learned in junior high school mathematics:
The first volume of Grade 7 contains six chapters:
The test sites involved in this chapter of senior high school entrance examination are: unfolding and folding, three views, all of which are relatively basic test sites, and one topic is usually examined in multiple-choice questions.
The test sites involved in the senior high school entrance examination in this chapter are: the concept of rational numbers (positive and negative numbers, rational numbers, antonyms, reciprocal, absolute values, number axis), the operation of rational numbers (addition, subtraction, multiplication and division powers), and the scientific counting method for representing large numbers. It often appears in multiple-choice questions and fill-in-the-blank questions in the senior high school entrance examination, and the difficulty is relatively small.
The test sites involved in this chapter are: the coefficient and number of monomials, polynomial expressions and coefficients, similar terms, combinations of similar terms, addition and subtraction of algebraic expressions, and the law of removing brackets, which are also some basic test sites. Fill-in-the-blank questions and multiple-choice questions generally examine conceptual knowledge points, and the first few questions in the solution generally examine algebraic addition and subtraction operations, generally using algebraic multiplication.
There are few test sites involved in this chapter of senior high school entrance examination, but the knowledge points in this chapter are the basis of junior high school geometry learning, especially the midpoint and angular bisector of line segments, which are the basis of straight line and angle calculation. Although the senior high school entrance examination will not directly examine the contents of this chapter, the basic contents of geometry must be mastered.
Test sites involved in this chapter's senior high school entrance examination: In solving problems, you will find equation application problems, which are usually combined with the comprehensive examination of functions, equations and inequalities, and generally there are fewer questions to examine linear equations. The solution of linear equation is very important. Although the senior high school entrance examination will not directly examine the solution of a linear equation, it is the basis of junior high school equation learning. The solutions of binary linear equations, quadratic equations and fractional equations to be learned later need to be applied to linear equations, which can be solved by elimination, simplification and rounding, especially in the study of linear functions.
Test sites involved in the senior high school entrance examination in this chapter: collation and analysis of statistical charts. The senior high school entrance examination usually involves an application problem, which is relatively simple and generally involves two kinds of statistical charts. When solving problems, it is generally necessary to complete statistical charts, analyze various statistical data, and estimate the overall situation through samples. It will involve some contents of the second grade, such as average, median, mode, etc. When you have time, you will also examine variance, range and standard deviation.
The first volume of Grade 7 contains six chapters:
The test sites involved in this chapter are: power operation (same base powers's multiplication, same base powers's division, power of power, power of product), operation of zero exponential power and negative exponential power, scientific counting method for expressing small numbers, multiplication and division of algebraic expressions, application of multiplication formulas and simplified evaluation of algebraic expressions. The study of factorization is related to algebraic multiplication, including the study of later fractions, which requires the knowledge of algebraic multiplication and needs to be practiced and consolidated during holidays. Generally, there will be two or three questions related to the operation of algebraic expressions in the senior high school entrance examination paper. Multiple-choice questions and fill-in-the-blank questions will be tested for power operation, calculation questions in analytical questions will be tested for real number operation, and algebraic expressions of negative exponential power test with zero exponential power will be simplified and evaluated.
The test sites involved in the senior high school entrance examination in this chapter: the nature and judgment of parallel lines are the necessary contents of the senior high school entrance examination. Generally, there will be a question related to parallelism in the multiple-choice or fill-in-the-blank questions in the senior high school entrance examination paper, which is often combined with the internal and external angles and theorems of triangles, special triangles, angular bisectors, etc. It is not difficult.
This chapter is about the test sites involved in the senior high school entrance examination: the relationship between edges and corners of triangles, the sum theorem of internal angles and external angles, the classification of triangles, the important segments in triangles, the judgment and properties of special triangles, and the judgment and application of congruent triangles. Among them, congruent triangles's judgment is the key point. Most senior high school entrance examination papers will have a question that directly examines congruent triangles's judgment and nature, and congruent triangles's judgment and nature are often used in some geometric inquiry questions and geometric synthesis questions. Triangle is the foundation of junior high school geometry, and the content of this chapter is not difficult, so we should spend more time reviewing and consolidating this part in summer vacation.
The relationship between variables is to lay the foundation for learning functions later, which is the difficulty of junior high school mathematics. The content of this chapter is rarely directly examined in the senior high school entrance examination, mainly for learning functions in the future. However, it is not difficult to express the relationship between variables with images in the senior high school entrance examination papers of some provinces and cities. In order to learn the following functions, it is still necessary to spend more time consolidating and reviewing.
The test sites involved in this chapter are: the nature and judgment of axisymmetric figures, the nature of common axisymmetric figures (isosceles triangle, equilateral triangle, bisector of angle, median vertical line of line segment), and the axial symmetry change is essentially congruent change, which is related to folding in geometry. In recent years, it is more and more difficult to fold, translate and rotate the three major changes of geometric figures in the senior high school entrance examination papers.
The test sites involved in the senior high school entrance examination in this chapter: the calculation of the probability of possible events will be directly examined in the senior high school entrance examination, and then further study will be carried out. Generally, it is necessary to draw a tree diagram or a table to analyze and calculate, and the senior high school entrance examination will be directly examined, which is a relatively basic topic.
In the summer study, you can combine the above analysis of the key points and test sites in each chapter, first review and consolidate the knowledge points involved, and then find some related test questions, especially the real questions in this province and city in recent years, analyze the frequency of each knowledge point and test site, examine the types and difficulties, and practice more. On the one hand, you can master the test sites involved in the content of grade one, and then fully master the questions with 20-30 points. On the other hand,
My son got poor grades in mathematics in the first grade. According to the meaning of the topic, it seems that he has given up hope for his children. The first day is the beginning of children's junior high school life. From this point of view, the children in the first grade are at the same starting line, and their math scores are poor, which can be reversed. They should not lose confidence in their children because of one achievement, especially as parents, and should be full of hope for their children and make them confident in their studies. If parents think that their children's math scores are poor and there is no hope of getting points, then if children know their parents' emotions, they will definitely lose confidence in themselves and give up on themselves. This is the most terrible!
First, children have bad study habits! Primary school didn't develop good study habits! Don't listen carefully in class! Homework can't be finished seriously!
Second, children have neither good study habits nor effective supervision and management by parents!
Third, children can't adapt to the learning life of junior high school and can't learn junior high school knowledge! This kind of situation is generally less!
First, parents accompany you!
Children's learning should be grasped from both classroom and after class! Parents should play a major role in their children's homework! Therefore, it is a very good method to insist on accompanying reading. Parents can read books while the children are doing their homework. The main purpose of parental supervision is to enable children to concentrate on independent boys. In the process of children's homework, don't be half-hearted and don't copy homework.
Second, the home-school alliance!
The child's poor grades show that the child must not have listened carefully. Therefore, as a parent, you can contact the teacher to understand the performance of your child in class. Listen carefully to the teacher's advice, unite with the teacher and correct the children's bad habits in class. Ensure that children are efficient and effective in class.
Third, make up lessons to improve!
Just as the summer vacation is coming, you can use it to help your children with what they have learned in the second volume of the seventh grade and review and consolidate it. Although paid tutoring is completely banned now, I believe there will still be some tutoring institutions to find a tutoring class suitable for children and review what children have learned. I believe it will have some effect. In the process of children attending remedial classes, parents and teachers should always keep in touch and communicate, keep abreast of the children's class situation, and ensure that extracurricular counseling is effective and not a mere formality.
Fourth, get to the point!
In order to improve children's grades as soon as possible, it is necessary to sort out and understand according to the corresponding mathematics textbooks, and understand what the learning focus of seventh grade mathematics is. Children can consolidate and improve in a targeted manner when reviewing. Junior high school mathematics focuses on cultivating children's computing ability and basic thinking. Especially in the seventh grade, mathematics is basically based on calculation. Take the mathematics textbook published by New People's Education Press as an example. Some main chapters, such as the operation of rational numbers, the addition and subtraction of algebraic expressions, the operation of real numbers, the calculation and application of linear equations with one variable and linear equations with two variables, and the calculation and application of inequalities and inequality groups, are all aimed at cultivating children's basic operational ability, and they do not require very high skills and methods. Children can master certain operation methods, and then practice a lot, and they can master them skillfully!
Finally, no matter how bad the children's grades are, parents will always be their strong backing. At no time should they lose confidence in their children. Sometimes, they should help children find self-confidence in learning and convince them that they can do well. Don't give up easily! I hope my answer can help you!
Your child's grades in the first grade are not good now, and there is every hope to get a score!
Junior high school mathematics knowledge is not much, but it is so much over and over again. A little more difficult may be in the third grade, such as quadratic function, circle and similarity.
And it's only the first day, so don't worry too much. It's too late to try now.
Every chapter of junior high school mathematics has its key problems. You can buy well-known materials in the market to get these questions, so that children can study and do them seriously. As long as you persist in studying for half a semester, you will definitely see the results.
Of course, if the child's self-control is a little poor, you can also find an experienced and responsible teacher for the child and take the child to study, so that the child's promotion speed will be very fast.
I studied in a small village in primary school, and then I went to the city in junior high school. At that time, I couldn't keep up with the rhythm of other children in junior high school. At that time, the perfect score in mathematics was 120, and I got 40 points in one semester. Later, in the next semester, I bought reference books, and I followed them slowly (it was not popular for us to make up lessons at that time). After half a semester's hard work, my junior high school is over.
Because the overall content of junior high school mathematics is not much, it is entirely possible to improve it.
You have found the right person. I am a senior high school student for more than eight years. Freshman didn't score arts and sciences. I just entered high school with a fractional line, and my math is very poor. At that time, my math score was 120, with more than 70 points several times and more than 80 points occasionally. I studied liberal arts in my sophomore year. There are 66 students in my class, and I rank 33, among which I got 33 points in math, which is the second from the bottom. The enrollment rate at that time was 7: 1. I thought it was impossible to go to college without math. In the third year of high school, I enrolled more than 30 repeat students. However, after hard work, in the regional quality test one month before the college entrance examination, among the students in the class 100, I got 95 in mathematics, ranking ninth, ranking 17 in the total score of the class, and was admitted to the college entrance examination.
Experience: First, use the basic principles of philosophy to guide learning, such as principal contradiction and secondary contradiction and their mutual transformation, quantitative change to qualitative change, internal and external factors, etc. Secondly, following the step-by-step process, it is easy first and then difficult. For example, learning math starts with multiple-choice questions. Finally, pay more time and energy than others, study persistently, and adjust your physical condition at the same time.
Of course, there are many differences between junior high school and senior high school, just borrowing and signing.
First of all, as a parent, you must have hope first.
When I was in junior high school, I had a classmate who was at the bottom of primary school and counted down from grade one. I don't know why I worked hard in the second grade. I went from grade 800900 (about 1300 in the department) to grade 1005. At that time, the class teacher was shocked. 30 days before the third grade, the senior high school entrance examination was admitted to Licheng No.2 Middle School (Jinan No.2 Senior High School).
Don't believe it, it's true. So as long as you have hope, anything is possible.
There is definitely hope to get points. During the epidemic, I instructed a friend to bring my son, a senior one, to score points. It only took about three weeks, and he rose from more than 50 points to 75 points.
Simply put, the next three steps:
Step 1: Parents should sort out the goals they want to score.
Since it is a poor grade in the first grade, it shows that the child has not adapted well to the study in primary school. If children are allowed to set their own goals at this time, they are likely to fall into a situation where their grades cannot be raised, and parents need to intervene.
A confident goal is to improve the score a little bit in combination with the current exam results. Don't think it is too simple or too difficult, which can enhance children's learning motivation. So my friend wanted his son to get more than 85 points from the beginning, and he adjusted it to 70 points in the first month.
Finally, my son took the exam in three weeks and got 75 points. Everyone is very happy. Then, his confidence increased greatly and he was willing to set higher challenges. I hope he can get 85 points next time.
Step 2: After you have a goal, you should check the missing knowledge points.
In fact, mathematics is mainly about conceptual understanding and operational ability.
We should not only master the concepts, but also practice more questions. If your child has a goal, you can also refer to the first step. Don't make your daily study tasks too difficult. Do it bit by bit, enhance children's confidence and become willing to do it.
If there is too much homework to make up, it is recommended to find a professional math teacher or tutor to make up the explanation of knowledge points, and there are also online classes.
That's all that matters. Children are in a state of high efficiency, that is, they are willing to take the initiative to do everything, and there will be higher standards.
Parents can care more about their children in the process, stimulate their children's learning motivation by encouraging and providing necessary help, and let them find a sense of accomplishment in every little study, which is the source of their learning motivation.
The overall difficulty of junior high school is moderate, and the children's mathematics is poor and the elementary school foundation is still weak. Junior high school is difficult to change. I estimate that children have less math training in primary schools! For example, primary schools insist on learning Olympic mathematics, etc ... I think the current task is to thoroughly understand the knowledge points in math books and then do exercises, so that the scores can be improved quickly. Before instructing a child to get more than 30 points in the first grade math test, he got more than 70 points after tutoring, and then he could get more than 80 points close to 90 points. Children in the first grade must still have great hope. The key is to find out the weak points of basic mathematics knowledge. The child I mentioned is now studying in Jiangxi Province. There are several Tsinghua Peking University students this year!
There is hope, and it is no problem to master the basic knowledge, not to mention the great potential of boys.
As a senior one math teacher, I think I have more say. First of all, analyze whether the math foundation of your doll primary school is weak. This depends not only on her primary school grades, but also on her mathematical thinking. If you tutor dolls for a long time, you will analyze them. Secondly, from primary school to senior one, we need to adapt as soon as possible. I found that many dolls in the class are still in the passive learning state of primary schools, and they will not take the initiative to review, but rely on teachers to help them review. When I first entered the first grade, I learned a lot of knowledge, but the foundation was poor and I couldn't keep up. My kung fu is usually done, especially according to the teacher's requirements, from the writing format to the usual homework. Third, the method must be correct, the formula must be memorized and practiced more, and the foundation must be laid first. Fourth, dolls of this age are active, so we must strengthen self-discipline, especially in class. It is common for many dolls to fight when the teacher is not paying attention in class, and they can't control themselves at all. If you don't understand in class, you can't grasp the key points. Fifth, we must preview. I only think so much for the time being. Find a reference.
Don't focus on the child's grades, but try to cultivate his interest in mathematics. As long as he is interested in mathematics, his grades will advance by leaps and bounds!
