1, let students operate and help them understand mathematics.

Hands-on operation is an effective means of mathematics learning, which can promote students' understanding of mathematics, help students communicate with mathematical language symbols and develop their sense of numbers.

2. Encourage students to think and explore independently.

It is necessary to provide students with the opportunity to explore independently, so that students can find and solve problems on the basis of discussion. Doing so can not only help students to further master basic calculations, but also help to cultivate students' awareness of inquiry and cooperation.

To guide students to think and explore independently in teaching, we need to do the following work:

(1) It is necessary to create vivid and concrete teaching situations so that students can be diligent in thinking and willing to explore.

(2) We should arrange some exploratory and open questions.

3. Encourage students to cooperate and exchange, and cultivate students' sense of cooperation.

In order to promote students' cooperation and communication, it is necessary to change the teaching organization form and teaching method, and gradually change from a single class teaching system to a diversified organization form with rich connotations and conducive to students' active participation. Group learning is such an effective form of teaching organization.

When guiding students to cooperate and communicate, we should pay attention to the following requirements:

(1) It is necessary to create a cooperative communication situation and cultivate students' sense of cooperation.

(2) Reasonable grouping. In grouping, we should consider the differences of students' abilities, interests, gender and background, and follow the principle of "heterogeneity within groups and homogeneity among groups" to ensure that each group can carry out cooperative learning at roughly the same level.

(3) Clear the goal of group cooperation. Cooperative learning is initiated by teachers, and teachers are not one of the parties in group cooperation. This characteristic of "external initiation" determines that it is very important for students to understand the cooperation goals. It is very beneficial for students to operate in groups to sort out and fill the obtained data into simple statistical tables.

(4) Reasonable division of labor, clear responsibilities, and teaching students the skills of communication and cooperation.

Second, the "new curriculum standards" requires independent cooperation and inquiry learning methods:

"Mathematics Curriculum Standard for Full-time Compulsory Education (Experimental Draft)" (hereinafter referred to as the new curriculum standard) points out: "Effective mathematics learning activities cannot rely solely on imitation and memory, and hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics."
