Jade design baseWhen designing the base of a jade artifact, many factors needed to be considered. The first was the choice of materials. High-quality materials could not only better place jade ornaments, but also improve their ornamental value. For example, the jade seal with a pure gold base weighing five kilograms, such a combination showed the magnificent royal style. A good base could also increase the value of the jade, including increasing its economic value. It could play a tangible protection role for the jade and facilitate the preservation and collection of the jade. Secondly, he had to consider the theme, color, and size of the jade in order to choose a suitable base. The most important thing was the suitable base. A suitable base matched with the jade could play the role of finishing touch and perfectly interpret the culture contained in the jade. For example, the 42-arm, thousand-hand, and thousand-eye Guanyin jade carving full of Buddhist aura perfectly combined with the matching base, presenting the solemn culture of Buddhism very well. In addition, in the process of creating some jade carvings, there would also be jade carvers who would design and create the base of the work.

##2. Reflection on Teaching
1. ** Success **
- The visual teaching effect was good. Through visual teaching methods such as physical display, animation demonstration, and group measurement activities, the students had a clearer understanding of the shape characteristics of the cylinder and cone as well as the concept of perimeter. Most students could accurately calculate the circumference of the bottom of a cylinder and cone, and could apply the relevant knowledge to simple practical problems.
- Teamwork stimulated learning enthusiasm. The development of group activities allowed students to learn from each other and inspire each other through cooperative inquiry, increasing students 'participation and enthusiasm for learning. In the group discussion, students could actively think about the relationship between the side development of the cylinder and cone and the circumference of the bottom, and come to the correct conclusion.
- Connecting it with the reality of life to deepen their understanding. In the homework, students were required to measure and calculate cylindrical and conical objects in their lives, so that students could feel the wide application of mathematical knowledge in their lives and further deepen their understanding of knowledge.
2. ** Inadequacies **
- Some students still had difficulty understanding the cone's side profile. Although they had demonstrated and explained it, some students still found it difficult to understand the relationship between the arc length of the circular cone and the circumference of the bottom. It was easy to make mistakes when solving related complicated problems.
- The difficulty level of the classroom practice was not clear enough. In the classroom practice session, for students with better foundations, some of the questions were less difficult and did not fully develop their potential. For students with weaker foundations, some of the expansion exercises were too difficult, causing them to be afraid of difficulty.
- The timing was not accurate enough. In the group activity segment, because the students were discussing more enthusiastically, they spent more time. As a result, the classroom practice and summary segment were a little rushed, and the students were not allowed to practice and review their knowledge.
3. ** Modification measures **
- In view of the difficulty of the cone side development drawing, more diverse teaching methods were adopted. For example, they could make a conical model that could be disassembled and assembled by the students themselves, so that they could feel the relationship between the arc length of the fan and the circumference of the bottom more intuitively, or they could add some targeted special exercises to let the students deepen their understanding in the practice.
- To improve the design of classroom exercises. The practice questions were divided into three levels: basic, improvement, and expansion. They were arranged according to the different learning levels of the students, so that every student could get effective training in the practice.
- More precise control of teaching time. Before the group activities, the time limit for the discussion was clearly informed to the students. During the inspection process, the teachers guided the students in the direction of the discussion in time to ensure that each teaching session could be carried out according to the plan to avoid situations where the time was too long or too short.
