First, cultivate students' awareness of active learning, cultivate students' awareness of active learning, and make the originally boring mathematics more interesting. Being interested in mathematics is the foundation of learning mathematics well. After a semester's mathematics study, most first-year primary school students are not ignorant of mathematics, but have preliminary computing ability. Therefore, when teaching "Understanding Numbers within 100", I let the students observe the classroom first, let them look for the numbers they can see in the classroom, such as the number of people and desks, and then lead the students to visit the campus to find out what numbers are there. Let the students say the numbers related to themselves, and see who speaks more and speaks well. Let the students feel that there are always several classmates around them, and their lives are full of mathematics, which enhances their interest in learning mathematics. Second, creating a strong learning atmosphere and lively and interesting learning situations is the guarantee to learn mathematics well. Playing is a child's nature. Even if children are playing, they can constantly accept new knowledge and new things. How do children acquire knowledge in play? According to the different learning contents of each class, I arranged and designed many different games and stories. For example, in the teaching of "position", I asked the students to talk about their position in the group and then played a roll call game. In this way, students can not only accurately grasp different positions, but also learn to think, and can communicate with each other at the same table and between the front and back tables, automatically point and identify different directions and positions. Children who are moving are particularly active and gradually develop their hands-on ability. 3. Guiding students to observe, think and solve problems from different angles is an important way for students to learn mathematics well. Nowadays, there are many exercises in mathematics textbooks with non-uniqueness characteristics, which requires us to seize the opportunity, encourage students to develop the good habit of thinking more and thinking more, and arouse their enthusiasm. At first, it was mentioned that the answers were different. When who could answer them, many students' expressions were blank. At this time, the classroom was silent. I will slowly prompt and encourage everyone to raise their hands at once. Some students are positive, some are right and some are a little off-center, but obviously, everyone wants to express themselves actively and try to think. I think the effect of praising everyone is not as good as that of praising individuals, especially students with poor grades, and everyone's enthusiasm will be higher. This will make children dare to speak and put forward different opinions in the future. Different analysts will have different conclusions about the problem, and cultivate students' ability to express their analysis results. Of course, teachers who make mistakes should also correct them. Make students learn to observe problems from different angles, think about problems in different ways, solve problems by different means, and fully realize the diversity of methods to solve the same problem. Fourth, cultivate children's life practice ability and let students apply what they have learned. It is said that "knowledge is power", and only practice can play the role of knowledge. Many students do well in school, but in practice, many students can't do it on their own. In other words, if you learn but don't know how to apply it, mathematics will lose its meaning if it can't be effectively linked with life. Therefore, it is also very important to cultivate students' practical ability in mathematics teaching. In each class, the teacher should first ask the students some practical questions, and the teaching process is the process of guidance, and then let the students use what they have just learned. In this way, students' personal experience and practice can improve their ability to apply mathematics. For example, after learning the lesson of "position", let students tell their position in the classroom and know the relativity of front, back, left and right. When you know the knowledge of money, play games to let students buy books or pens with pocket money, so that students can know how much money they have spent, how much money they have left and how many things they have bought. In this way, students have been trained in practice, and mathematics has really integrated into their real life. In a word, mathematics comes from life and is a summary of people's practical experience in production. Teachers should let students know that mathematics knowledge is indispensable in life practice and one of the necessary weapons to transform nature. Educating students to learn mathematics well is to make it more convenient to use in the future and to get a better life.
