Abstract: The cultivation of abstract thinking ability is an important learning task in primary school mathematics teaching, an effective way for students to know, like and master mathematics, and the basis for cultivating students' innovative consciousness. Cultivating students' abstract thinking is a step-by-step process, which requires teachers to dig deep into teaching materials, innovate teaching methods, fully mobilize students' initiative in learning, guide students to think positively, and constantly improve their abstract thinking ability in the process of thinking.

The design concept of the new curriculum standard for primary school mathematics clearly stipulates: "Mathematics is a science that studies quantitative relations and spatial forms. Mathematics is closely related to human activities, especially with the rapid development of computer technology, mathematics is more widely used in all aspects of social production and daily life. As a scientific language and tool gradually formed by abstracting and summarizing objective phenomena, mathematics is not only the foundation of natural science and technical science, but also plays an increasingly important role in social science and humanities. " From this article, we clearly know that the cultivation of abstract thinking ability plays a very important role in the future development of students. Abstract thinking is an indirect and generalized response to objective reality by using concepts, judgments and reasoning. Cultivating students' abstract thinking is conducive to training students' thinking ability, which is a prerequisite for students to learn mathematics well. Now I will talk about my own views on how to cultivate students' abstract thinking.

First, effective use of learning tools.

In primary school, students
