For middle school students, it does not disturb classroom discipline. Sometimes you wake him up, and he doesn't know what you are talking about. For them, it is absent-minded. We should constantly remind them to pay attention and organize more classroom teaching.
For underachievers, first of all, don't set too high a goal for them, but let them jump up and reach their goals, so that they can feel hopeful and taste the joy of success. As long as they make a little progress, they should be praised at an appropriate time. Let them feel that the teacher has not given up on them, and they still have great hope to improve.
In addition, teachers should create a relaxed and harmonious learning atmosphere in the classroom. No matter how angry and anxious you are during the class, you should hold back and explain patiently during the class. Always remember: there are no students who can't teach, only teachers who can't teach. Be a teacher that students like. Only when students like you will they be willing to study this subject.
Mathematics education should be oriented to all students, everyone should learn valuable mathematics, everyone can get the necessary mathematics, and different people can get different development in mathematics. Teachers pay attention to teaching methods, strive to change students' learning methods, take various measures to stimulate students' interest in learning, and always take students as the main body, so that students can establish concepts, understand concepts and apply concepts in the learning of active participation, operation, communication, brainstorming and speech inquiry, so as to make the classroom full of vitality for teachers and students and make the classroom more exciting.

Since teaching, I have spent a lot of time teaching mathematics, but I don't have much time to experience it. Through my own accumulated experience in the teaching process, combined with the exchange of other teachers and the requirements of the new curriculum reform, I summed up some experiences and understandings about the first volume of mathematics teaching in the third grade of primary school. First, make unremitting efforts to do oral calculations.
1, according to the students' oral calculation in the teaching class, make specific training objectives for this semester.
(1) The purpose of oral arithmetic training is not only to improve students' oral arithmetic ability, but also to pave the way for the study of Units 4 and 6 in this book.
(2) As the fourth unit is to learn to multiply two digits by one digit, some special oral calculation questions such as 25×2, 25×4, 15×2, 15×3, 15×4, 65433 can be appropriately added in the oral calculation training.
2. According to the teaching progress and students' mastery, regular oral arithmetic test or final standard test can not only help students find the motivation to learn, find the gap, but also let parents know their children's computing ability. At the same time, teachers can also analyze and find the breakthrough point to make the training effect better.
Second, in the operation activities, let students understand the arithmetic and algorithm of written division.
In the teaching of pen-based calculation division, students can learn more about the arithmetic and calculation methods of pen-based calculation division by dividing one point with real objects. For example, 24÷2=, let the students divide the prepared straws and say how you calculate them. Which number should I count first? It is not enough to practice only one question, but also to put 1-2 ways to tell the calculation method. Because there are no calculation rules in the book, the teacher still has to write the method on the blackboard in teaching. Whether it is pen multiplication or pen division, we should also pay attention to cultivating students' estimation ability in teaching. Estimation is one of the better means to verify the calculation results, but it is often forgotten or slightly used in teaching and has not become a "good helper" for students' calculation.
Such as: 2 1× 428× 6 ()× 6
125÷596÷863÷3360÷3
Third, strengthen the connection between mathematics knowledge and life.
For the knowledge closely related to life: odometer, circumference, year, month and day, students can find things related to knowledge around them in teaching, and deepen their understanding through observation, comparison and analysis, thus strengthening their concepts.
For example, the "odometer" allows students to calculate the distance between the electric quantity and the chronograph in kind, and find out the relationship between them after observing and understanding. After class, students can be arranged to find some living objects around them to judge which weight unit is more suitable, and then exchange judgments after filling in.
The unit "perimeter" not only makes students feel novel, but also is one of the difficulties in this book. When preparing lessons, the teacher thinks it is very simple, that is, to find the sum of all sides of a closed plane figure. To find the perimeter of a rectangle and a square, just remember the calculation method. In real teaching, I found that students can't understand and solve practical problems as quickly as the teacher imagined. The main reason is: 1, less contact with the concept of "perimeter", students do not fully understand. 2. When you don't understand the concept, and after learning the calculation method about the perimeter of rectangle and square, you don't understand the origin of the method and only remember the formula, so you can't write it when you encounter a flexible topic.
Fourth, pay attention to the integration of information technology and primary school mathematics.
With the continuous development of science and technology, teachers, students and multimedia have become the three elements of classroom teaching system. Proper use of multimedia courseware in primary school mathematics teaching can stimulate students' interest and enthusiasm in learning, so that students can acquire knowledge more easily, happily, quickly and efficiently, develop their thinking and form their abilities, thus achieving the effect of cultural teaching.
In the past classroom teaching, I tried my best to arouse students' enthusiasm. Even the most basic teaching tasks can't be completed without doing well and mobilizing students' enthusiasm. Using multimedia demonstration to stimulate students' cognition and knowledge drive children to be naturally curious. When they are exposed to new things, they often have a desire to explore. We can use this feature to stimulate their interest in knowledge and learning, which is the starting point for students to learn knowledge well and develop their intelligence. Therefore, in teaching, using vivid, visual and audio-visual forms to turn static graphics in books into dynamic graphics will help to communicate the relationship between knowledge and graphics, promote students' curiosity, enhance their interest in teaching and improve their analytical ability, so as to firmly grasp students' attention and make them enjoy and love learning. Creating colorful audio-visual learning situations with the help of multimedia can not only stimulate students' senses, stimulate their interest in learning and arouse their curiosity, but also enrich their knowledge representation, reduce the learning difficulty and encourage them to actively participate in the learning process.
In primary school mathematics teaching, concepts, laws, laws, etc. They are all important and difficult points, and these knowledge are abstract to some extent, so it is difficult for students to form a new cognitive structure. If the courseware is used to demonstrate the dynamic image, it will lead the way in the movement, dynamically show the evolution process of things and show the whole process to students. In this way, not only the highly abstract knowledge can be demonstrated intuitively, but also its dynamic demonstration is helpful for students to understand the essential attributes of concepts.
Pupils are emotionally unstable and easily tired, and their thoughts are the easiest to slide down during the consolidation process. Only by constantly giving students new stimulation can we maintain strong combat effectiveness. Let students learn knowledge in a relaxed and pleasant atmosphere, use knowledge and entertain education, thus changing "passive" learning into "active" learning and improving classroom teaching effect. At the same time, the use of multimedia technology saves the time of writing on the blackboard and wiping, and can provide students with a lot of exercises in a short time, which greatly increases their ability to practice. Moreover, a question bank can be set up, so that students at different levels can choose different types of difficult topics to practice, teach students in accordance with their aptitude, get timely, appropriate and appropriate training, and let "top students" eat cymbals and "middle and lower students" eat cymbals, thus reducing the burden and increasing efficiency.
