Help students purposefully discover mathematical problems related to collection and social practice, and try to solve them with the mathematical methods they have learned, so that social practice and mathematics can be integrated.

Introducing teaching experience from life practice; Mathematics is everywhere in life. In teaching, we should reasonably observe, punish and test the theory of "Goo Goo Tea and Taichao Coffee", introduce concepts from practice, and increase students' understanding and interest in concepts.

The comprehensive practice of mathematics in primary schools covers a wide range of activities, including research-based learning, community service and social practice, labor and technology education, information technology education and so on.

First, interaction and cooperation.

1 refers to the implementation forms and strategies of teacher-student cooperation and interaction in the comprehensive practical activity course. Two-way interaction, emotional communication and cooperative participation are the basic characteristics of interaction. Emphasize the two-way communication and transmission of information and emotion with the participants who advocate the implementation activities, and participate, guide and interact with each other.

2. Questions can be set and asked, group cooperation and collective discussion, teacher-student cooperation, etc. Require two-way exchanges and cooperation between teachers and students; Encourage students to actively participate, respond positively and create boldly.

Second, independent inquiry.

1, that is, inquiry learning is not only a learning field of comprehensive practical activities, but also a way of learning activities. Inquiry learning refers to a learning activity in which students choose and determine research topics from nature, society and students' own lives according to their own interests and under the guidance of teachers, and actively acquire knowledge and apply it to solve problems.

2. Inquiry learning emphasizes that students enhance their awareness of inquiry and innovation through practice, learn scientific research methods, and develop their ability to comprehensively apply knowledge. Through research-based learning activities, students form an active, vivid and independent cooperative inquiry learning mode.

Third, the teacher's guidance.

Teachers' independent topic selection and active exploration activities are the key to the implementation of the comprehensive practical activity curriculum. Students' learning style will directly affect the implementation and effect of activities. Therefore, students should master independent learning methods under the guidance of teachers.
