1. Pay attention to the actual level of students, step by step. When you start writing, don't start too high. The choice of writing content and form should not only consider students' actual ability and level, but also consider whether students have the ability and conditions to observe, test and experiment. Without practical and reliable material data, it is impossible to write articles with scientific value. The value of a math paper has little to do with the size of the topic, and a small topic can still write a big article. Beginners had better discuss one problem at a time. The topic is time-consuming and laborious, and it is not easy to make it clear, so it is often impossible to write it. The topic is narrowed, the argument materials are easy to collect, and the writing difficulty of the article is also reduced, which is conducive to students' participation. 2. Pay attention to the practical mathematics around students and make it practical. Primary school students have limited mathematical knowledge, energy and time. Teachers should pay attention to closely combining students' study and life reality when instructing students to write math papers. Teachers can guide students to choose some topics, so that students can write according to their own personal experiences, which is easy for students to accept and understand and is conducive to writing. For example, after learning the area unit and the area of rectangle and square, let the students measure and estimate the area of desks and classrooms themselves, and write the process of practical activities into mathematical papers. For another example, in order to educate students to save food, students can investigate and count how many kilograms of food are wasted in the school cafeteria every day, and what can be used for the food saved by the school in one year. Only in this way can students have activities, thinking and content to write. 3. Pay attention to cultivate students' sense of participation, and let students actively write math papers. The subject of teaching is students. Only when students actively participate and turn math papers into conscious actions can this activity achieve the expected results. The purpose of writing is to improve students' learning enthusiasm, change passive learning into active learning, and cultivate students' autonomous learning ability and innovative consciousness. Due to the limitation of primary school students' knowledge and ability, most students are unlikely to write high-level compositions. For students, the greatest significance of writing mathematical papers is participation. In the process of participating in writing activities, students' ability is improved and their talents are displayed.
