The teacher's nickname is "Lao", and king of the children's abbreviation is "Wang", which is my respectful name for the math teacher Wang. Judging from his appearance, he is quite a learned man. His thick black hair is obedient to the curry hose, his nose is high, his chin is firm, his lips are tight, and his sharp eyes are shining with wisdom. On the first day of school, Mr. Wang hurried into the classroom with compasses, lesson preparation books and books. He put down his things, looked at 70 serious faces around him, then went to the blackboard, smoothed his hair and began to scribble. In an instant, the three Chinese characters "Wang" clearly appeared on the blackboard. He looked up and said loudly, "My name is Wang, and everyone will call me Lao Wang from now on!" " "Lao Wang?" Interestingly, we were amused by him. I tell you quietly here that he is not old at all, only in his forties. "Stupidity" may be a patent for students, but Lao Wang, as a teacher, likes to use "stupidity" on himself. The other day when we were in the class of "Integer and Number Axis", Lao Wang was embarrassed to say that he still didn't understand. Teach yourself, discuss and summarize, and then tell you. The students are both excited and excited about their studies. After some hard work, everyone was ready, eager to try and raised their hands. "Ok, please ask Teacher Zhao to come to the stage!" Lao Wang invited Zhao Yang to sit in the student seat. Zhao Yang speaks generously and seriously, just like a teacher. Teacher Wang listened attentively, sometimes nodding in agreement, sometimes shaking his head against it, and sometimes raising his hand to ask questions. The classroom atmosphere is so active and the knowledge learned is so flexible. Zhao Yang say that finish, Lao wang's eyebrows relaxed. He strode onto the platform and asked, "Do you understand?" "I understand!" Under the stage, everyone said in unison, "Who will summarize" and "I ..." The students scrambled. A math class was so easy. It turns out that Lao Wang is not stupid, but to arouse everyone's interest in learning. The pen and eraser are going to fight. There was silence in the classroom, and everyone was fighting in the examination room! The topic was very simple, and soon, most of the students finished, secretly engaged in "underground activities". I was absorbed in assembling the car, but I didn't know that Lao Wang was eyeing me. Finally, I woke up suddenly in the laughter of my classmates. Looking up, I just bumped into Lao Wang's eyes. I was flushed and ashamed. I really want to find a hole to get into. Unexpectedly, Lao Wang picked up my test paper and scored full marks without looking at it. Then I gave full marks to several students who deserted, and the classroom was boiling. The students all handed in their examination papers to Lao Wang. After the goal, Lao Wang returned to the podium with a sly smile. "What do you think of simple and stable, I'll give you full marks. However, when marking papers, if mistakes are found, they will be deducted twice. " "ah!" We "winners" have carefully examined each other. Lao Wang really has a knack for treating us. Look, Lao Wang's flexible, vivid and humorous way of giving lectures has aroused our enthusiasm for learning and enabled us to learn knowledge in a relaxed and pleasant atmosphere.
