1. The "three-dimensional goal" in primary school mathematics teaching refers to students' emotions, attitudes and values. In classroom teaching, we should introduce vivid life themes into the classroom, skillfully apply students' life experiences to the classroom, activate the classroom with life problems, and activate students' thinking with existing mathematical reality, which will make the mathematics classroom moistened by the water of life, thus making mathematics learning more interesting and attractive.

2. In classroom teaching, students' mathematical emotions are often stimulated by problem situations and thus cultivated. Problem situations are emotionally attractive and easy to stimulate students' interest in learning. Creating problem situations is not an easy task. Ask clever questions and be attractive. In practice, teachers can combine students' age and psychological characteristics, interspersed with some interesting and novel situations, and stimulate students' love for mathematics.

3. Students are living people. They have independent thoughts and will, and it is difficult to forcibly control them. Students' emotions are directly related to the adjustment and control of classroom teaching rhythm. In a class, if the students are depressed, restless and frightened, the teacher can't achieve good results even if he dances and talks eloquently. On the contrary, a warm and cheerful classroom atmosphere will make students like math and fall in love with math classes. As long as students have positive feelings about mathematics learning, they can keep the motivation of mathematics learning and get results. Therefore, teachers must pay attention to students' emotions, adjust the teaching rhythm at any time and create a relaxed, democratic and harmonious classroom atmosphere.
