This paper introduces the lateral area, bottom area and surface area of a cylinder, and knows that there are many objects in the shape of a cylinder in life. In the previous study, application principle and class summary, we already know the cylinder:

Math lesson plans involve content 1) teaching objectives, knowledge and skills, emotional attitudes and values; 2) key points and difficulties in teaching; 3) introduction of teaching process (specific links can be set according to content), exploration of new knowledge and summary of homework; 4) design of blackboard writing; 5) reflection on teaching; teaching process in the lesson plan of "surface area of a cylinder" in primary school mathematics: introduction of new lessons. Look at this cylindrical object. Its production requires certain materials (showing a tea box). Please think about it. How much material does it take to make such a tea box? Process and method, generation principle and deepening principle? (Explain while demonstrating) 2) Generation principle: 1) Introduction of new curriculum teachers, in-depth exploration, consolidation and improvement. For example, we are actually asking what a cylinder is: asking "the materials needed to make a tea box" is actually asking the lateral area and two bottom areas of the cylinder (during the demonstration). We call the area of the side of the cylinder the area of the side of the cylinder.
