How to teach the first-grade primary school mathematics well (1) Teachers who attend the lower-grade primary school mathematics class will feel a series of problems, such as less teaching content, students' initiative, uneven students' existing knowledge level, and great difference in problem-solving speed, which will lead to chaotic classroom discipline, difficult management, inability to learn subjects and inaccuracy in learning. How can we have a good class, which can not only ensure the smooth completion of teaching objectives, but also let students study quietly and happily?
1. Grasping students' psychological characteristics and developing colorful teaching activities are the prerequisites for a good class.
Children in the lower grades of primary school are active, curious and like new things. We will seize this feature and activate boring mathematics knowledge. Such as designing solve riddles on the lanterns, telling stories, playing games, small competitions, hands-on operations, situational performances and other activities in teaching, so that children can approach mathematics, experience mathematics and feel the infinite charm of mathematics in the activities, and mobilize students' consciousness of consciously learning mathematics and using mathematical thinking to solve life problems. For example, I designed the first-grade course "Looking for the Law of Numbers"? Mathematical military training? In the game, I asked all the children to come to the stage in a row (like soldiers) quickly and neatly, and then reported the odd and even numbers one by one, so that the children could find the laws between the numbers and the characteristics themselves. My students like this activity very much. They quickly master what they have learned and use it flexibly. Through this activity, the feelings between classmates have been enhanced.
Second, strict classroom routine is a necessary condition for a good class.
The new curriculum advocates students' hands-on practice, independent exploration, cooperation and communication, which really makes the classroom? Live broadcast? Get up. Behind the seemingly lively, there is actually impetuousness. Only when teachers come in and out freely can they become the organizer of the classroom and the guide of teaching. Therefore, teachers should cultivate children's good study habits and strict classroom routines from the lower grades. For example, raise your hand first, don't answer first, sit still after completing the task, take the school tools carefully, please put them away after use, and so on. The use of sticks, counters, cards and other mathematics learning tools makes the teaching content intuitive and vivid, but if it is not properly managed, it will also cause unstable factors? The culprit? . Sometimes a student plays a whole class with them, and it is conceivable that his listening efficiency is very low. If students are asked to put their used learning tools in the hole in the desk every time, they will not be distracted. Whenever we listen to a high-quality class, we are deeply impressed by the good quality of the students besides enjoying the wonderful lectures given by the teachers. Compared with our noisy classroom, it is very important to strictly demand the routine of the classroom. Once students form good study habits, they will benefit for life.
Third, giving full play to the role of the group is an auxiliary condition for a good class.
There is a big difference between junior students' existing experience and their own quality. For example, when I was teaching "Knowing Time" in senior one, some students couldn't master the time and minutes for several days, but some students knew the 24-hour timing method for a long time. This knowledge point is required for the second year of high school. This situation is very common in junior high school math class. In order for all students to learn, teachers have to repeat what students know over and over again regardless of the present situation. At this time, these good students may become problem students who bring unstable factors to the classroom for a time. In order to maintain classroom discipline, teachers treat them badly. In the long run, these students will feel tired of learning, which will greatly dampen their enthusiasm for learning and cause a vicious circle. If teachers can make full use of the learning form of group cooperation, give full play to the role of these people and help those students with learning difficulties in a comprehensive way, they can not only stabilize these children, but also avoid repeated learning, curb the vicious circle from the source and achieve a win-win situation. Cooperative learning is an important learning method and teaching organization form advocated by the new curriculum standard. Junior high school students' cooperative consciousness and ability are limited, so it is necessary for teachers to give strategic guidance.
Of course, in addition to these points, teachers still have a lot to do. We should study hard, explore actively, and try to make every lesson thoughtful? Lejiale's math class is orderly, effective and harmonious.
How to have a good first-year math class (2) I think math teachers under the new curriculum should find the growing point in teaching, pay attention to students' development and ensure students' interest in learning. Only by respecting and trusting students in teaching can teachers put students in the main position of classroom teaching. Classroom teaching is an organizational form of teacher-student interaction, with flexible teaching methods and flexible use of teaching materials.
First, create a situation and create a learning atmosphere
Mathematics teaching should be closely linked with students' real life. Starting from students' life experience and existing knowledge, we should create vivid and interesting situations to guide students to observe, calculate, guess, reason and communicate, so that students can master basic mathematical knowledge and skills through teaching activities, initially learn to observe things and think about problems from a mathematical point of view, and stimulate students' interest in mathematics and their desire to learn mathematics well. In the practice of mathematics teaching, it is very important to create situations. Because mathematics situation is not only an important source for students to master knowledge, form ability and develop psychological quality, but also a bridge between real life and mathematics learning, concrete problems and abstract concepts, and an effective means to stimulate primary school students' interest in learning. For example, the first class of grade one, classification, we designed one? Small department store? Situation. Through the creation of this situation, students realize the necessity and significance of classification and have a desire for classification. Then, they create a situation to organize children's learning tools. Through division of labor and cooperation, independent exploration and hands-on practice, students can experience the process of classification and complete the teaching objectives easily and happily in the whole classroom.
Second, independent exploration, cooperation and exchanges.
The learning mode of independent exploration and cooperative communication provides all students with opportunities for success. In the process of independent exploration, cooperation and communication, through the form of group cooperation, each student can put forward his own problem-solving methods, share other people's problem-solving methods and discuss the advantages and disadvantages of different methods. This is very beneficial to develop students' problem-solving ideas, enhance their self-confidence and cultivate creative thinking. For example, in the teaching process of carry addition within 20, after students find mathematical problems from their life situations, we are not in a hurry to teach students algorithms, but leave this learning task to students completely, let them explore and find solutions freely, and allow students of different degrees to have different algorithms, which not only keeps the diversity of problem-solving strategies, but also cultivates the flexibility of students' thinking.
How to teach mathematics well in the first grade of primary school (3) The students in the first grade of primary school are all newly enrolled children. They are naive and romantic, love to talk and move, have poor binding force on their own behavior and are easily distracted. In class, I sometimes play something unrelated to my study for a while. Traditional teaching thought regards these characteristics as shortcomings that affect students' learning and restrict them? Moving? , mandatory lectures, and some still think it is suffering? ADHD? . They don't concentrate in class, teachers criticize them and parents blame them. They seem to be bound by their hands and feet in class, bound by their thinking, and completely in a passive position. After the last class, they were bitter and tired, and they were tired of learning since childhood. In the long run, a large area of backwardness will be formed, which will accumulate over time and delay the child's life. If our first-grade teacher can make children feel the joy of learning as soon as they go to school, it will be of great benefit to cultivate children's strong thirst for knowledge, good thinking quality and study habits from an early age.
First, at the beginning of the story, create scenes and create a strong classroom learning atmosphere.
If students want to learn well, they must first solve the problems they like to learn. Cultivating students' curiosity is closely related to cultivating students' interest in learning. Children aged six or seven just entered school and began to learn cultural knowledge, still immersed in the world of fairy tales. I imagine the activities of small animals in my mind. They like to listen to adults telling them stories about small animals. Every time I take a new lesson, I write a story according to the content of the textbook, create a situation from the beginning of telling the story, and then ask a group of enlightening questions to introduce the new lesson. There are more than forty students in each class in our school. It is difficult to maintain teaching order only by teachers controlling classroom discipline. But when it comes to telling stories, the classroom immediately quieted down and everyone pricked up their ears.
Second, cultivate children's habit of listening attentively.
Listening attentively is the basis of students' active participation in the learning process and positive thinking, and it is also the premise of improving classroom learning efficiency. Therefore, teachers should cultivate students' habit of listening carefully in class. In order to attract students' attention and make them concentrate on listening in class, I think teachers must be full of energy, vivid and interesting language, clear organization and flexible methods when giving lectures, so as to make classroom teaching attractive and make every student happy to listen.
Third, we should pay attention to cultivating students' habit of speaking boldly and well.
Strengthening the training of speaking and cultivating the habit of speaking in teaching will help students to feedback learning information, enable teachers to grasp students' understanding of problems in time, facilitate targeted measures, cultivate students' oral expression ability and promote students' thinking development. In the class, there are always some children who dare to speak, and many students are too timid to speak. The most important thing is to let students have the courage to speak. In view of reality, I always use people who dare to speak to drive and inspire those who are afraid to speak. In teaching, I give timely praise to those students who love exploration and are willing to set an example first. The students are really brave and have a loud voice to answer questions. ? Students really use their brains; What you said is great. Wait a minute. For those students who are not good at speaking and are afraid of speaking, I will give them expectant eyes and encouraging eyes, give them proper guidance and timely guidance, and enhance their courage and confidence. As long as they can speak, even if their voices are outrageous, I will treat them with encouragement and make him feel that he can speak, even if he is wrong.
