As a teacher, we must consider how to tap the interesting factors of teaching materials, and try our best to stimulate students' interest in learning mathematics according to their psychological characteristics such as curiosity, thirst for knowledge, activeness and competitiveness, so as to make the teaching process full of waves and vitality. In order to cultivate primary school students' interest in mathematics and receive better teaching results.

First, arouse interest with questions.

Einstein said, "Interest is the best teacher". There are many ways to stimulate interest, and asking questions is an effective way to stimulate students' interest. Teachers should be good at putting new problems to be solved consciously and skillfully in all kinds of old knowledge that are in line with students' actual situation, causing a suspense in students' psychology. Putting students in a "tried" situation can stimulate their curiosity and thinking ability, and stimulate their interest in knowledge and desire for knowledge.

Second, the interest in seeking beauty.

Psychological research shows that everyone likes to feel the beauty of things and has the pursuit of beauty. Mathematics is full of beauty such as simplicity, harmony, symmetry, singularity, form and solution. When students think about the objective laws implied by mathematics, they have endless memories of the simplicity and harmony of mathematics itself. When they suddenly understand strange, complex and profound mathematical problems, they have an indescribable sense of surprise, pleasure and accomplishment, so they are intoxicated and appreciate the charm of mathematics. Enjoying all kinds of fun in the beautiful world of mathematics will make students have a strong love for mathematics learning. For example, I am teaching "axisymmetric graphics"? At first, I showed some paper-cutting art with axisymmetric characteristics from the perspective of appreciation, in order to mobilize students' existing life appearance; Then I personally cut (or tear) leaves, butterflies and other pictures as observation objects, introduce the knowledge of "symmetry" and inspire students to explore symmetry. In the course of the new lesson, we show students things with axisymmetric characteristics in all aspects, so that students can appreciate the beauty of symmetry and enrich their perceptual knowledge. At this time, in the minds of students, axisymmetry has been painted with a mysterious color, which touches their heartstrings and inspires their desire to explore.

Third, realize interest with differences.

Pupils have a different psychology, that is, they want to be different and different. Therefore, cultivating students' divergent thinking is not only the requirement of mathematics teaching, but also in line with students' wishes and psychological characteristics. Whether it is concept teaching, rule teaching, calculation teaching or application problem teaching, students should be induced to think about problems from different aspects, different angles and different levels, so as to fully and accurately grasp the content of learning, experience the charm of mathematics and have a strong conscious motivation.

Often used in teaching, trying to tell more, thinking more about a problem, solving more problems and changing more questions will bring great happiness to students. As I once designed such a topic:? = 1, create situations in teaching to make students think from multiple angles, which leads to students scrambling to say various answers:

(1) 1+0= 1 (by addition); (2) 100-99= 1 (by subtraction); (3) 1× 1= 1 (multiply); (4)8÷8= 1 (by division); (5)2/5+3/5= 1 (think about the whole 1). This greatly mobilized students' learning enthusiasm and achieved good teaching results.

In short, students are the subject of learning, not the container of knowledge. We should make great efforts in teaching, be good at stimulating students' interest in learning and fully arouse their enthusiasm for learning.
