Comments and suggestions on the circumference

The draft and suggestions for evaluating the circumference are as follows:

The circle is the last plane figure in primary school. Students' understanding of learning straight lines and curves, both the learning content itself and the method of studying problems, has changed, which is a leap in learning.

Through the study of circle, students can understand the basic methods of learning curve graphics, and at the same time penetrate the relationship between curve graphics and straight graphics. This not only expands students' knowledge, but also enters a new field in the concept of space.

Therefore, through the study of circle-related knowledge, students can not only deepen their understanding of the surrounding things and stimulate their interest in learning mathematics, but also lay the foundation for studying cylinders and cones in the future.

After listening to the teacher's lesson "The Area of a Circle", I was deeply inspired and felt that this lesson was very traditional, solid and successful.

Because teachers delve into textbooks, accurately understand the intention of compiling textbooks, scientifically grasp textbooks, carefully design and effectively carry out teaching activities, all teaching objectives have been implemented, and teachers' leading role is closely combined with students' main role, which strengthens the reasoning and verification of teaching interaction and students' experimental operation.

Students should be given some time to think and discuss (shortcomings of new teachers, pay attention to controlling the rhythm and language of class)?

It has played a certain role in improving students' quality and cultivating their innovative consciousness and practical ability, and achieved good teaching results.
