What efforts are there? Parents should care more about their children after work. Children's stress may come from parents' high demands. The happiest thing for children is to get their parents' approval. What are some ways to share their efforts with you?
What efforts are there? Seventh grade math 1 poor math foundation. You can pay attention to the foundation, summarize, learn to sort out the wrong questions and summarize the methods.
1, lay a solid foundation and start from scratch.
A journey of a thousand miles begins with a single step. The first day of junior high school should start with the most basic mathematical knowledge, keep down-to-earth and make steady progress, and recite the basic definitions, concepts, formulas and theorems of mathematics.
2. Understand the learning methods and choose the appropriate learning methods.
There are many ways to learn mathematics. You can consult some math experts in class to see how they learn math. In addition to consulting a math master, you can also consult a math teacher. After all, the math teacher is the leader of the subject.
3. Learn to do your homework correctly
When doing homework, you should be good at thinking. If you do it for the sake of doing it, you lose the meaning of your homework. Therefore, students must seriously think and find out the shortcomings.
4. Pay close attention to teaching materials and do a good job of "two regression"
Teaching materials are teaching materials, and they are teaching blueprints jointly compiled by the Ministry of Education and the top experts in electricity and salt in China, which are related to the fate of a country and the rise and fall of a nation, because cultivating successors is a major event related to the survival of the nation.
5, sorting out the wrong book
For the questions that are easy to make mistakes, you should record a mistake book, which can be a good way to check and fill in the gaps and prevent mistakes from being made again.
What efforts are there? Seventh grade math 2 1. Learn first-year math, and pay attention to some details of the teacher's lecture in class.
Although it is impossible to concentrate completely in a class, Mr. Jin still advises students to listen attentively as much as possible, because every detail the teacher says may be very important and may help you understand every knowledge point in the book well.
Senior one students must not take it for granted that this knowledge point may not be tested, and that knowledge point is not the key point, so it doesn't matter if you don't listen carefully. It is very unacceptable to hold such a mentality. When listening to the class, students must consciously take every detail of the teacher's lecture as the key content to learn, so that students can achieve better results in the mathematics learning stage of senior one.
2. When learning mathematics in the first grade, the training of extracurricular exercises should account for at least 6-80% of mathematics learning.
After all, mathematics is still a subject that emphasizes practical application. Perhaps, if you review the theoretical knowledge points for an hour, you might as well do the specific 10 question. Constantly doing problems is of great help to the improvement of math scores.
Therefore, students must do more extracurricular exercises when they study mathematics in senior one. In this regard, Mr. Spark Education Jin specially suggested that senior one students should pay special attention to the choice of math extracurricular books, a good math extracurricular book that suits them and a general math extracurricular book. Their "mathematical reactions" are quite different.
Teacher Jin suggested that students should choose extracurricular books from well-known publishing houses when purchasing extracurricular books on mathematics in Grade One. Of course, a more efficient way is to ask the teacher for advice. It would be more perfect if the teacher could help them choose a counseling book.
3. When learning mathematics in the first grade, you must not be afraid of the questions.
Teacher Jin told the students that it is definitely not difficult for us to stay away from difficult problems in the first year of learning mathematics. Maybe there are few problems in mathematics in senior one, but in junior two, when we take the senior high school entrance examination for mathematics, math problems are necessary.
Therefore, in the learning stage of grade one, students should train difficult problems. Only with more training can students really win difficult problems and get higher scores.
What efforts are there? 3. First, we should constantly cultivate our interest in learning mathematics and desire for knowledge.
Many students have had this feeling in primary school. Whenever you know a mathematical law and solve an application problem, the joy of success is irreplaceable by anything else. It stimulates your enthusiasm and curiosity about learning. The more you learn, the more you love learning. Interest in learning and thirst for knowledge should be constantly cultivated. Besides, students have just stepped into the big garden of "the kingdom of mathematics", and many mysterious and endless mathematical problems are still waiting for you to learn, watch and study.
Second, we should form the good habit of studying hard and thinking independently.
In the past, some students thought that learning mathematics mainly depended on listening to the teacher in class, and regarded our math textbooks as "problem sets" for homework. There are two cognitive problems that must be solved. First, students should realize that our textbook records the basic knowledge that mathematicians must master and how to use this knowledge to solve problems. Therefore, in order to truly acquire knowledge, study hard and cultivate self-study ability is the fundamental way. We hope that with the guidance and help of middle school teachers, students will change from not reading in the past to loving and learning to read, and then form a good habit of reading carefully; Second, students should also realize that many math problems are not solved by teachers alone, but mainly by students themselves. Confucius said, "Learning without thinking is useless, and thinking without learning is dangerous." This sentence brilliantly expounds the dialectical relationship between learning and thinking, that is, learning and thinking, thinking and learning. The process of learning mathematics is mainly a process of continuous in-depth thinking. We hope that everyone will take math classes in the future. No matter how teachers talk about new lessons, review or comment on homework exercises, they should keep a high degree of concentration, actively think about problems while listening, capture useful information, and seize budding inspiration at any time. For problems that you don't understand, you must solve them in time and actively until you understand them.
When learning the basic knowledge of algebra, can you ask yourself the following questions by reading books? Try to solve it. For example, why use letters to represent numbers? What is algebraic expression? What is the key of column algebra? How to express a law by algebra? Wait a minute. In addition, when doing exercises, if you encounter an algebraic expression of the square of the product of the sum of two numbers and the difference between these two numbers, do you know what are the different quantities? How to use letters to express and which mathematical operation symbols to connect can reflect the hierarchical internal relationship between quantities and transform literary language into algebraic language, that is. If it is written, it is not the original meaning. In junior high school, a big difference from studying mathematics in primary school is that I have learned many mathematical concepts, especially rational numbers. Because mathematical concepts are the basis of our judgment and reasoning and solving problems, we must understand them accurately. Although mathematical concepts are often abstract, they are all abstracted from concrete cases in real life. Therefore, when learning mathematical concepts (such as positive and negative numbers, number axis, absolute value of numbers, etc.). ), we should pay attention to combine them with actual life production, and we will summarize and summarize the essence of the concept from specific cases. When reading a book, we should grasp the key words in the concept definition and think about its connotation, so as to understand the textbook. We believe that a large number of students will improve their self-study ability by cultivating the habit of studying hard; Improve your thinking ability by cultivating the habit of independent thinking.
Third, we should always grasp the important basic topic of how to "progress from arithmetic to algebra"
Generally speaking, the mathematics content of first-year algebra is mainly to solve important basic problems from arithmetic to algebra. We think it is mainly reflected in the following two aspects. On the one hand, it is "number set expansion", that is, introducing negative numbers to expand the original arithmetic number set into a rational number set; On the other hand, it is the principle and method of solving algebraic equations, that is, from expressing numbers with letters to solving application problems with "column equations" instead of "column formulas".
Every expansion of the number set is the need to solve practical problems and the contradiction of mathematics itself. The establishment of the concept of rational number, the introduction of the nature of rational number and the regulation of rational number operation rules are all necessary preparations for students to further study algebra. When studying the chapter of rational numbers, I hope everyone can consciously cultivate their logical reasoning ability, observe, compare, analyze, synthesize, abstract and generalize, and use induction and analogy to reason. In addition, we should pay special attention to improving our computing ability and have excellent basic computing ability. Therefore, we can not only operate correctly according to laws, operating rules and formulas. , but also understand the calculation principle, so that the operation can be "reasonable, simple and accurate" according to the subject conditions. In order to solve the limitation of solving application problems by arithmetic, people come up with letters to represent unknowns, and algebraic equations to represent the equality relations in problems. Because the letters representing unknowns are also numbers, we can also operate according to the generality and general method of digital operation, so as to get the appropriate value of unknowns. Students should pay full attention to this "historic" breakthrough. Therefore, it is necessary to master not only the deformation and calculation of arithmetic with numbers, but also the deformation and calculation of algebraic expressions with letters (mainly algebraic expressions at present), as well as the basic methods and steps of solving equations, all of which are carried out in order to solve application problems with column equations. Through the study of solving practical problems with equations, we can understand how to abstract practical problems into mathematical problems, deal with mathematical problems with equation ideas, form the consciousness of using mathematics, and cultivate our ability to analyze and solve problems.
Fourth, improve learning methods and grasp every link of mathematics learning.
Many students who are good at mathematics have their own learning methods that are in line with their own reality, and they can better grasp all aspects of mathematics learning. For example, make a study plan for each stage; Earnestly study and preview math textbooks before class; Concentrate on every math class with "questions" and think positively; Review what you have learned in time after class, finish your homework independently, solve difficult problems seriously and timely, and correct mistakes in your homework; At the end of each unit, make a review summary, systematically sort out the knowledge and the types and methods of solving problems, prepare carefully before the exam, and pay attention to summing up experiences and lessons after the exam; In addition, I insist on participating in extracurricular group activities and reading math tutorials. All these show that the whole process of learning activities is an interrelated and organic systematic project. Although it seems like a cliche, it is not easy to stick to it. Need to have a high degree of enterprising spirit, diligent and practical learning attitude, tenacious learning perseverance. We suggest that students should focus on overcoming a shortcoming and solving a problem at a certain stage of their study. Students help each other, learn from each other, strengthen the atmosphere of research and discussion, catch up with each other and promote each other, so that all of us can lay a solid foundation for future study in the first semester of senior one. I wish the students a great improvement in their mathematics learning level and ability under the guidance of teachers and their own efforts.
