The fourth grade of primary school is a transitional period. We must cultivate good study habits and a good study atmosphere. However, it is really not easy for students to concentrate on a 35-point class, even for good students. When the teacher is giving a lecture, he must make them pay attention to the teacher.
For gifted students, some clever boys are very active. If you want to grasp his thinking, you must leave him in suspense, and what attracts him most is whether he wins or not. I once taught Zheng Xuan, who was very clever. I often leave them questions at noon. Because of his carelessness, he seldom does everything right. So I used this to educate him not to always think that he is smart and can learn without an open mind. If we hit him, he can go to class for several days at a time. Therefore, more attention should be paid to eugenics in class.
For middle school students, it does not disturb classroom discipline. Sometimes you wake him up. He doesn't know what you are talking about. Remind them to pay attention and organize more classroom teaching.
For underachievers, the first goal set for them should not be too high, so that they can't jump up and reach. In this way, they not only felt hope, but also tasted the joy of success. As long as they make a little progress, they should be praised in time. Let them feel that the teacher has not given up on them, and they still have great hope. Warm them with love and let them experience love. If they want to succeed, they must help them more after class. It is easy for them to stick to their poor foundation, so tell them some very simple knowledge to make them progress little by little. Besides that, as a teacher, we should speak softly in class. Create a relaxed and harmonious learning atmosphere, so that students should hold back and explain patiently no matter how angry and anxious they are during the lecture.

Essays on mathematics teaching in the fourth grade of primary school 2 1. Decimal shift
This lesson mainly teaches students to master the changing law of decimal size caused by decimal point movement through mathematics. Using the movement of decimal point to solve related problems, expand students' thinking, cultivate students' ability of independent inquiry, cooperation and communication, and apply knowledge to solve practical problems.
1, I changed the boring calculation teaching and started with the guessing games that students like, so as to stimulate their strong thirst for knowledge. Taking the teaching materials as the main line, focus on guiding students to find that the decimal point will be restored to the original110 if it is moved one place to the left. When the decimal point is moved two places to the left, the decimal point will be restored to the original1100.
2. Let mathematics come from life. After discovering the rule that the decimal point moves to the left, I asked the students to guess what would happen if the original number moved to the left by four or five digits, and then asked them to boldly guess what would happen if it moved to the right. Then let the students cooperate with the students in the group to explore the changing law of decimal expansion caused by the right shift of decimal point.
3. Cleverly set the theme and let mathematics go to life. I give appropriate advice and help to students who have difficulties in exploration. After individual students explain the rules, I also ask students to give examples, so that the conclusions can be justified and all students can have a cognitive process. In the whole teaching process, I just play the role of guide and participant. Guide students to apply what they have learned in mathematics to reality, so as to realize the application value of mathematics in real life, and then cultivate students' awareness of applying mathematics and their ability to solve problems comprehensively.
4. Reflecting on the whole teaching process, there are many problems at one time. First of all, children are more cautious in class, which I think is directly related to the training on weekdays and the lack of inspiring language in the teacher's class. Secondly, the whole teaching design pays too much attention to children's oral expression ability and lacks written exercises. These problems are exactly what I want to improve in my future teaching work.
Second, "careful calculation"
"Careful Calculation" is the first lesson of Unit 5 of the fourth grade primary school mathematics published by Beijing Normal University. The teaching of this course focuses on letting students discover the calculation method of fractional division with integer divisor through independent exploration and communication with the help of life experience and existing knowledge, and experience the significance of fractional division in practical situations. Pay attention to the following points in teaching:
1, review the related knowledge of division and decimals before class. Although students have experienced the learning process of integer division, they have forgotten what they have learned to varying degrees because of the long time interval. By reviewing the meaning of decimals, it is helpful for students to explore the arithmetic and algorithm of decimal division. Therefore, from the perspective of students' learning process in class, it is necessary to review before the new lesson.
2. Pay attention to the close connection with real life. Real life is not only the source of computing teaching, but also the destination of computing teaching. By creating the scene of buying milk from the top 100 supermarkets and supply and marketing malls that students are familiar with, we can find out which store has cheap milk, highlight the theme of careful calculation, and naturally introduce fractional division, so that students can feel the significance of fractional division in specific situations and stimulate their interest in exploring fractional division.
3. The new curriculum standard of organizing students' independent inquiry and cooperative communication requires students to experience the learning process of mathematics, learn knowledge and master the learning methods of mathematics in the process of independent inquiry and cooperative communication. In the process of learning arithmetic, master the decimal point of quotient and the decimal point of divisor, add zero to the decimal part before division, and leave the class to the students completely. As the instructor and organizer, the teacher allows the students to explore themselves and organize students to ask questions and discuss together. However, after hard work, students still have obstacles in understanding the arithmetic of fractional division. At this time, teachers should change their roles and participate in students' discussions. Pass? Jiao yuanfen? Prompted by knowledge and decimal meaning, the students saw the road sign of progress, and the ship that was about to stagnate raised its sails again and broke the waves. At this time, the teacher quietly retired to the background to appreciate the collision of students' wisdom.
4, return to life, consolidate and improve This lesson has designed two exercises. The first one is jam, which closely follows the theme of careful calculation and consolidates the knowledge just learned. The second is about the openness of this year's snowstorm, which can not only expand students' thinking but also achieve the purpose of caring for education. In the teaching process of this course, I still have many shortcomings. In particular, it needs to be improved in standardizing the classroom and digging deep into students' thoughts.
Third, "Who climbs fast?"
In the "Who climbs fast" class of Beijing Normal University, it is actually the teaching of circulating decimals. Personally, I think the content is very simple and can be solved without class, but this is not the case. In teaching, I have encountered many different accidents, and my exercises have not been implemented. I will summarize myself and learn to summarize, which may make me progress:
1, I may be too wordy, sometimes I talk too much, which makes students feel bored and uninterested. 、
2. The example you choose may not be novel and can't arouse students' interest. Interest is one of the best ways to arouse students' enthusiasm.
3. I have a bad teaching mentality, so I should correct it. New teachers will inevitably have doubts and difficulties. 4. I don't know some mathematical concepts and the whole mathematics textbook system of Beijing Normal University. The content is not coherent.
Fourth, the balance game (equation)
The teaching purpose of this lesson is to let students find that the equation is still valid by adding (or subtracting) the same number on both sides of the equation through balanced games; Ask students to solve simple equations with the properties of the discovered equations. In the textbook published by People's Education Publishing House, students are required to master the relationship between addition, subtraction, multiplication and division before learning to solve equations, and then use: one addend = and-another addend; Subtraction = subtraction+difference to find the unknown in the equation; The current textbook of Beijing Normal University is the method of solving equations with balanced games. I really don't know what this design looks like because I came into contact with this textbook for the first time. In teaching, I try two different teaching methods in two classes. The first class is designed according to the textbook, and the second class observes the students' learning effect according to the method taught by the predecessors. By comparison, I found that students find the present method easy to understand and use. In the teaching process, several good students immediately thought of the method of subtracting an addend from the unknown, but for most students, the method of adding or subtracting the same number on both sides of the equation at the same time is easier to understand, and sensitive students can do it in one step. Students' activities are very interesting, and they realize the methods to solve problems from them. With timely guidance and guidance, they feel that the teaching task of this class has been successfully completed.
In the long-term primary school mathematics teaching process, I think the fourth grade is a transitional period. Before the fourth grade, they were still naughty and active, but from the fourth grade, they must be cultivated with good study habits and excellent study atmosphere. However, it is really not easy for students, even good students, to be able to concentrate on the lecture at 45 points in a class.
For intelligent and active gifted students, if you want to grasp their thinking, you must leave him in suspense and pay more attention to them.
For underachievers, first of all, don't set too high a goal for them, which will not only make them feel hopeful, but also taste the joy of success. As long as they get some achievements, they should be praised in time to make them feel that the teacher has not given up on them and they still have hope. Warm them with love and let them experience love. It is necessary to create a relaxed and harmonious learning atmosphere in the classroom, so that students can accept new knowledge in a relaxed and happy mood, and gradually let students fall in love with mathematics and like learning mathematics.
