The course "Generation and Significance of Scores" taught by Mr. Chen establishes a student-centered and student-centered teaching method, gives full play to the charm of the new classroom, and makes full use of the classroom mode of learning first and guiding later, so that students can get better development. "A people-oriented teaching presupposition will certainly provide conditions for teachers and students to creatively exert their intellectual potential in the teaching process, and will certainly provide opportunities for every student to actively participate and actively participate."

In this lesson, Mr. Chen's presupposition of the generation space has left a deep impression on students' wise guidance for effectively constructing knowledge in the generation process.

Mr. Wang's class gives me the overall feeling that the classroom atmosphere is active, teachers and students cooperate tacitly, students have a strong interest in learning, and the whole classroom is relaxed and happy, and goes smoothly, especially the students' cooperative learning and independent inquiry are more prominent. Before students' cooperative learning, teachers put forward activity requirements to make students clear the cooperative learning goals. In the activities, teachers participate in each group to give timely guidance, and play the role of organizer and guide. When the group reports the scores created, the teacher also guides and inspires the camera, which plays the role of threading the needle.

Finally, by comparing the old and new knowledge, guide the students to say, "Divide the unit 1 into several shares on average, and such a number of shares is called a score."

At the beginning of class, Teacher Song encouraged students to fold up their learning tools and draw a picture. This sentence is like a stone thrown into calm water, which arouses students' strong thirst for knowledge and leaves enough time and space for students at all levels to think. This flexible presupposition has aroused great excitement among students.

Through hands-on operation, the students found eight sticks of circle, square, line segment, a box of chocolates, 12 round slice and14 respectively. Through students' orderly feedback and thinking collision, the teacher led the students to have a clear understanding of the unit "1". It was this process that naturally and skillfully explained the first difficulty of this lesson.

The Generation and Significance of Scores, taught by Mr. Chen, adopts a platform interactive classroom, and has successively built two multi-directional cooperative teaching platforms: the first platform is the front platform, which allows children to review the overall knowledge of the whole unit through after-class cooperation, complete the study card, and form a system of what they have learned; The second platform is to guide students to reorganize a certain part of their favorite knowledge in self-study so that knowledge can form a knowledge network.

In the classroom, Mr. Lei also pays great attention to the infiltration of knowledge about the history of mathematics, so as to let students know that it did not suddenly appear, but gradually formed after a certain period of time. Through appropriate exercises, guide students to understand the key points and difficulties in teaching. In teaching, Mr. Lei designed concise and appropriate exercises, which improved students to varying degrees. The design of exercises is distinct and gradual, which broadens students' thinking and is diverse but not boring. However, some students have different views when explaining exercises.
