[Write a math class] We have class 30, which is active, and write a math class. But in the 40-minute class, not only outstanding talents emerged, but also classroom troublemakers appeared. Don't believe it? Let me introduce them to you! Tian teacher, our math teacher, is about 40 years old. He is of medium height, with a smile on his face, a pair of glasses on his high nose, and gentle eyes under his gentle glasses. Teach bonzi teacher? Can he hit a student? Don't! Pointer is an essential part of his class, because he always demonstrates guidance on the blackboard with pointer. In this lesson, he will talk about the sum of the inner angles of polygons. First of all, he drew several polygons on the blackboard, which is too standard, showing how high his painting level is. He carefully explained to us the sum of the inner angles of a polygon, and accidentally said a wrong word (caused by nonstandard Mandarin). The students burst out laughing. He also smiled and said, this is a math class. I can't speak Mandarin well, so I can understand more. Mr. Wang asked: Yang, how many diagonals can a vertex of a Pentagon trigger? How many triangles do they divide the Pentagon into? What is the sum of the internal angles of a Pentagon? As soon as I finished, the students scrambled to answer. Mr. Wang said loudly: I'll let Yang answer, others don't talk too much! Suddenly, there was silence in the classroom. Mr. Yang took his time to answer the question, and Mr. Yang went on to talk about the formula. During the group discussion, he made a condition: which classmate shall I draw later? If no one answers, which group will sweep the floor! (Sweeping the floor is Mr.' s unique skill) So, everyone had a heated discussion. Where's sir? Patrol around and help some groups. Oh, wherever he goes, that stick is his good partner! He always pesters the team when asking questions, and he won't let go until he is at the end of his rope. After class, he finished his homework before he put down his beloved pointer, took the book and walked to the office with mirth. Li Guoxin, a student who raises his hand 40 times a week, certainly won't miss any chance to answer questions. Math class is also a good opportunity to earn opportunities! Although he is very small, his brain is very flexible. As soon as he asks a question, he raises his hand high. A pair of bright eyes looked at the blackboard, and clever ears listened carefully to every word the teacher said. When the teacher's question came, he immediately raised his hand, but the teacher didn't slap him. He didn't sigh like other students. The second question, he raised his hand again, but he still missed the draw. During the group discussion, I saw him seriously explaining to the students in the group (he sat in front of me, so I know better). When the teacher asked the group to report, he still raised his hand and looked at the teacher sincerely. This time, the teacher finally beat him, and he also reported the results of the group. The composition of the second day of junior high school is "writing a math class". I really admire his persistence. We should learn from him and learn his qualities! I don't know why his body is always shaking when he answers questions. I asked him several times with a smile: Why does his body tremble when he answers questions? He just smiled and didn't answer me. Also, when he answers questions, his eyes will unconsciously narrow into a crack, from which he will emit black light like ink. In short, in this math class or even all classes, he will definitely answer questions, and his enthusiasm sometimes drives me. I think: Maybe only Li Guoxin deserves the title of "Raise your hand". Tong Tong, a famous questioner, is a famous questioner in our class. He can be heard heckling in every class except Chinese. He is tall, fair-skinned and flexible. He is the sports committee member of our class. He is also a real troublemaker. Although he is active in class, he always likes to take advantage of loopholes and find faults. Let's talk about this math class. This kid is restless again. The teacher asked: Is there any other way to prove that the sum of the internal angles of a Pentagon is equal to 540? Divide the Pentagon into triangles and quadrilaterals, and the sum of the internal angles of the quadrilaterals is 360. Tian teacher said with a smile: How do you know that the sum of the internal angles of a quadrilateral is equal to 360? Prove it! He shouted to the teacher: teacher, this is an axiom, and people all over the world know it! Tian teacher said with a frown, I didn't learn, I don't know! Our classmates added: tian teacher's ignorance is a great blow to us. Later, I kept whispering that I didn't do well in the class either, alas! Distress! When other groups reported, he was there again! Sweep the floor! His shouts inspired the whole class, and some people followed suit, making it impossible for the students to go on. Tian teacher greets: Who is yelling at who, just follow them to sweep the floor! Tong Tong immediately stopped for a while. As a team leader, I often turn my head to remind him, but his answer is: I'm not the only one who is heckling! God, I'm so angry. Now, I have nothing to do with him, and I will definitely punish him with the law (class rules)! These are the theoretical figures of Theory of Three Represents in our class. After the math class of Another World, too many roles are deeply portrayed in my heart. Generally speaking, our class is also a crouching tiger, hidden dragon. I firmly believe that with our efforts, those lawless elements will be brought to justice! Yeah! Grade 2 of Chongqing Tongliang Bachuan Middle School, Tongliang County, Chongqing: Warm 20 1330
