1 How to improve the overall teaching quality of primary school mathematics
Using multimedia to stimulate students' interest in learning.
In the whole process of teaching cognition, students are the main body. In order to let students learn actively, teachers must improve their teaching methods. Teachers should make full use of multimedia teaching methods in teaching, optimize teaching environment and stimulate students' interest in learning. For example, when I was teaching the perimeter of a rectangle and a square, I played the multimedia courseware "Tortoise and Rabbit Race". The tortoise ran around a rectangular flower bed 5 cm long and 3 cm wide, and the rabbit ran around a square flower bed with a side length of 4 cm. They reached the finish line at the same time. Please help them find out who ran the long-distance race. This problem is to find the perimeter of a rectangle and a square. By watching the multimedia courseware, students have a good understanding of the concept of perimeter, help students analyze and understand the calculation methods of rectangle and square perimeter, stimulate students' interest in learning knowledge, learn mathematics in a happy and harmonious atmosphere, and improve students' ability to analyze and solve problems.
Strengthen students' hands-on operation ability.
Primary school students can't learn mathematics without concrete practical activities. Paying attention to students' hands-on operation is one of the most effective ways to develop students' thinking and cultivate their mathematical ability. After learning the area of a circle, I did an exercise for my classmates. The length of an equilateral triangle is 1.5 cm. Now, let's roll this triangle ABC along a straight line and find the distance length of point A (figure omitted). Looking at the students with a puzzled face, I said four words "hands-on operation", and the students cut out an equilateral triangle one after another and started to operate according to the requirements of the topic. After a while, the students found a solution to the problem according to their own operation. After the solution, I strike while the iron is hot, so that students can find out the distance between point B and point C. This kind of hands-on practice makes this problem difficult, turns abstract into concrete, further develops students' thinking, and embodies the educational concept of "learning by doing", thus making quality education truly implemented.
Skilled teaching methods.
According to the characteristics of primary school students' physical and mental development, it is an effective means to stimulate students' learning enthusiasm to properly carry out primary school mathematics competitions. Studies have shown that primary school students can often study harder under competition conditions than under normal conditions, and the learning effect is more obvious. In the competition, driven by strong competitiveness and curiosity, they always want to win the first place and always want to be praised by their teachers. We can use this psychology to greatly increase students' interest in learning and their perseverance in overcoming difficulties. In teaching, various competitions can be organized, such as "who is faster and who is right", "who knows more", "who is skillful in methods" and "who has more people", which can make students "show their talents". There are various forms of competition, which can be played by the whole class; Can be divided into male and female competitions; You can compete in groups; Students can also be grouped according to their abilities. There is no grouping principle here. In short, in order to make every pupil succeed in learning mathematics, we must find ways to make every pupil experience the pleasure of learning success, so that the motivation of pupils will be greater and their enthusiasm for participating in learning will be higher.
2 methods to improve the quality of primary school mathematics teaching
Use "living" teaching materials
Mathematics originates from life, and life is full of mathematics. In mathematics teaching, we should closely contact with students' real life, find mathematics themes in the real world, make teaching close to life, and let students see and touch mathematics in life. Therefore, students no longer feel that mathematics is the crown jewel, unattainable, and mathematics is a mirage divorced from reality. Mathematics education is to enable students to acquire the basic mathematics knowledge and skills necessary as a citizen, and introduce fresh topics in life into the big classroom of learning mathematics. For example, reform the form of work and highlight the application operation.
For example, after learning the common relationship between multiplication and quantity, I arranged for students to go to the vegetable market with their parents on weekends to buy food or shop, and calculated the price independently according to the unit price. The students were very interested. Pay attention to the practical operation of mathematics learning, straighten out the connection between learning and application, and make them closely combined. This is exactly what one-sided exam-oriented education is seriously lacking, and we must continue to strengthen the reform of mathematics teaching. For example, in the teaching of "yuan, jiao and fen", simulated shopping activities can be carried out; In the teaching of "classified statistics", students can count the classes to be studied in a week, the number of class hours in each class and so on. In the teaching of "meter, kilometer", I lead the students to the playground to count the steps and estimate the length.
Clever teaching methods
According to the physical and mental characteristics of primary school students, it is an effective means to stimulate students' enthusiasm for learning. Research shows that primary school students can often study harder under competitive conditions than under normal conditions, and the learning effect is more obvious. In the competition, driven by strong competitiveness and curiosity, they always want to win the first place and always want to be praised by their teachers. We can use this psychology to greatly increase students' interest in learning and their perseverance in overcoming difficulties. Various competitions can be organized in teaching.
For example, "see who can calculate quickly and accurately, and who can solve more", "see who has more clever methods" and "see which group has more people" can make students "show their talents". There are various forms of competition, which can be played by the whole class; Can be divided into male and female competitions; You can compete in groups; Students can also compete in groups according to their abilities. In short, in order to make every student succeed at all levels and try to make every student experience the happiness of learning success, people can and need to be motivated. Through encouragement, the enthusiasm of primary school students to participate in learning will be higher and the learning effect will be better.
3 How to improve the teaching quality of primary school mathematics
Mathematics teaching should pay attention to application and integrate theory with practice.
A good math class should not train people who can only take exams, and our society does not necessarily need so many "mathematicians". The vast majority of students will eventually become ordinary workers. Whether you continue your studies after graduating from middle school or take part in labor directly, what you learn in middle school should be "useful" and often used, so it should be different whether you go to middle school or not. Therefore, strengthening and teaching students the methods and abilities to solve practical problems should be an important basis for judging a math class.
A good math class should first pay attention to the vertical connection of students' knowledge. Mathematics itself is a romantic history with strict logic and interlocking links, with twists and turns. The knowledge learned later can be applied to the knowledge learned earlier, so that the original knowledge can be understood more thoroughly and mastered more firmly. Secondly, we should pay attention to the horizontal connection of cultivating students' knowledge. Mathematics is by no means a castle in the air built only for itself. Many mathematical knowledge and branches were originally introduced according to the needs of production or the needs of physics and chemistry, the only brother and sister of mathematics. For example, "calculus" was invented by Newton when he calculated the "law of universal gravitation". Therefore, it is a strategic move to abandon the closed discipline concept and integrate mathematics into the big classroom of science teaching. Third, we should pay attention to integrating theory with practice. Mathematical modeling is a good attempt. An important purpose of learning middle school mathematics is to guide practice and production in the future, from practice to practice.
Mathematics teaching should change the classroom goal from "learning" to "learning", and autonomous learning is an inexhaustible source of living water.
It is better to teach people to fish than to teach them to fish. Knowledge is endless, the speed of renewal is unimaginable, and students' school time is limited and precious. Therefore, it is more important and urgent to teach students to "learn". Autonomous learning is an inexhaustible source of living water, which can be enjoyed for a lifetime.
The emergence of inquiry learning has brought fresh rhythm to middle school mathematics teaching. A good math class should be a "clone" of research-based learning; Inquiry learning is research rather than research, focusing on learning. Its remarkable characteristics are autonomy, openness, inquiry and practicality; It breaks the traditional teaching mode that all students read the same book, do the same questions and listen to the same lectures. We should really put students in the main position of learning and take students as the center; Take society as the classroom; Take the process as the carrier; Taking comprehensiveness as the material feature embodies modern educational thoughts and concepts, which is an effective way to comprehensively promote quality education and cultivate students' innovative consciousness, practical ability, adaptability to social life, active development ability and lifelong learning ability. This is a real learning revolution; This is the basic feature of a good math class.

Change the teaching method of examples and make full use of the value of examples.
Examples are reflections of new knowledge. Grasp new knowledge points through teaching examples. The traditional teaching method is a topic, and only by finding the answer to this question can it be complete. When teaching examples, the author should give full play to the utility of examples, not only try to help students understand and master the solutions of examples, but also make various extensions and transformations of examples in combination with the actual situation, turning them into forms such as asking more questions, asking more questions and editing more, so as to fully tap the intellectual value of using examples. For example, after teaching engineering problems, you can change the plot of the topic and make it an encounter problem or a general compound problem. This not only stimulates students' interest, is conducive to learning, but also broadens students' knowledge, communicates the internal relationship between knowledge and cultivates students' adaptability.
Teachers should pay attention to the individual differences of students, so that every student can get full development.
Mathematics Curriculum Standard for Compulsory Education points out that mathematics education should be geared to all students. Realization: Everyone learns valuable mathematics, everyone can get the necessary mathematics, and different people get different development in mathematics. In order to promote the development of each student, mathematics education should not only lay a solid foundation for all students, but also pay attention to developing students' personalities and specialties. Due to the influence of various factors, students have differences in mathematics knowledge, skills, abilities and interests. Teachers should recognize this difference in teaching, teach students in accordance with their aptitude and guide them according to the situation. We should proceed from the reality of students, give consideration to students with learning difficulties and spare capacity, meet their learning needs through various ways and methods, and develop their mathematical talents. The new textbook designs many problems, such as "thinking", "exploring", "trying", "thinking" and "discussing". Teachers can choose according to the actual situation of students. For students with good math scores, they can also choose some flexible questions for them to think and explore, so as to expand their knowledge and improve their math scores.
Education is fun, and learning is fun.
Everyone knows that children are very interested in stories, fairy tales and animals. Therefore, the questions in the textbook are compiled into fairy tales and short stories, with small animals as the protagonists, so that students can be in an anthropomorphic world and "do what they like". This not only enhances the interest in classroom teaching, but also effectively mobilizes students' learning enthusiasm, so that students can devote themselves to mathematics learning. According to the characteristics of primary school students, we should create interesting learning scenes for them to stimulate their interest in learning, and closely combine the characteristics of mathematics to create learning scenes that make students feel real, novel and interesting, arouse students' busy doubts, create students' mentality of "thinking but not getting it", and promote students' cognitive mood to change from subtle to positive, from spontaneous curiosity to strong thirst for knowledge, resulting in eager subjective exploration consciousness and realizing classroom teaching.
