In the teaching of mathematics, graphics and geometry in primary schools, I start with the familiar life objects of students. Although primary school students have some life experience, they are curious about all kinds of things and phenomena around them. Therefore, in teaching, we should grasp students' curiosity, mathematize life experience and bring mathematical problems into life according to the characteristics of teaching materials and students' real life. For example, taking the classroom as the situation, let students know the position clearly; Learn cuboids, cubes, cylinders and spheres in a building block environment that students are familiar with. Let students take the initiative to learn in this situation. Hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics. There are many activities in the teaching content of graphic geometry. Learn in cooperation and experience the necessity and fun of cooperative learning. At the same time, in mutual communication, students' sense of participation is constantly cultivated. Through communication with others, I feel different ways of thinking and processes, learn different ways of thinking, try different ways of exploration, and constantly improve my thinking level. In teaching, students should be provided with opportunities for cooperation and communication, and the language of teachers and books should not be simply and mechanically imitated and memorized. In teaching, we should also pay attention to guiding students to think in the process of operation and combining operation with mathematical thinking. For example, after learning the area of rectangle and square, ask, "Can you complete the following measurement and calculation with your classmates?" Then ask the students to measure the real rectangle and square, and discuss and calculate the perimeter and area in groups.
In this way, letting students learn in life can not only improve their interest in learning, but also make learning easy and easy to master; It also makes students understand that knowledge comes from life and is used in life, so the teaching effect is better. The deficiency is that there are few realistic themes in remote mountainous areas, and sometimes they can't be found, so it is difficult to achieve the expected results, and more efforts will be made in the future.
