"Mathematics is an indispensable tool for people's life, work and study", "The understanding of mathematics should be understood not only from the perspective of the essence of mathematics, but also from the personal practice of mathematical activities". This fully shows that mathematics comes from life and is applied to life, and mathematics is closely related to students' life experience. In mathematics teaching, I find that mathematics teaching is always divorced from life, which makes the mathematics knowledge that students come into contact with more abstract and increases the difficulty of teaching. Therefore, I think teachers should fully explore the life and interest of mathematics knowledge in the research, mobilize students to be good at asking questions and doing independent research, actively seek the close relationship between mathematics and life, and explore the teaching methods of mathematizing living materials and making mathematics classroom life, so that students can master mathematics easily and happily. So I established a small topic-how to make primary school mathematics teaching alive.

Second, the purpose of the study

1, cultivate students' positive and stable learning attitude. While instructing students to learn mathematics knowledge, teachers guide students to explore the relevant background of this knowledge point from various channels, highlight the historical and realistic background of this knowledge in social life, present the process of knowledge generation, development and change, reveal the development law and essence of this knowledge, and understand its practical influence and practical significance on human social life, so as to enhance students' profound understanding of the practical significance given by relevant knowledge points and promote students to form a correct and stable learning attitude.

2. By guiding students to purposefully discover and collect mathematical problems closely related to their own lives from the daily life environment such as campus, family and society, carefully observe and record them, encourage students to actively look for problem scenarios in various ways, and try to use mathematical knowledge to analyze, discuss and explain from different angles, so as to guide students to express their different views in accurate, rigorous and concise mathematical language or words, thus strengthening the accumulation of students' mathematical life experience and cultivating students' initiative in mathematics learning.

3. Create a living mathematics teaching scene to cultivate students' interest in mathematics. Through the understanding of students' life and interests, based on students' life experience, teachers re-process and integrate the teaching content and reorganize the learning materials, so that the new form of knowledge presentation is close to students' life experience, that is, the teaching content is life-oriented.
