"wow! That is education for all! " At seven o'clock in the morning, I arrived early. In the hard search, I caught a glimpse of the signboard of the national education institution, jumped three feet high with excitement, and immediately crossed the road and ran to the blue two-story building.
As the first student to arrive, I waited at the door excitedly against the strong wind-this was my first time to attend a lecture in the group. After a while, several teachers rushed to open the door. I got the class permit, took a break and walked to Room 204.
Carefully walked into the classroom, suddenly looked up, and couldn't help but exclaim: What a beautiful classroom! Appreciate it carefully and find a seat to sit down. Teacher Shine Wong gave me the lecture notes and enthusiastically talked with me about the methods in course learning, which pushed my new reserve to the outside world. Just as he was talking, Teacher Guo Sanwei came into the classroom.
Near the end of class, because some students didn't come to the classroom, Mr. Guo decided to talk to us first-if the earth is tightly circled with a rope, and then one meter is added to this rope, can the distance between the circle surrounded by the rope and the earth make Mr. Guo climb over?
Hearing this strange question, I laughed to myself: of course not! One meter is too small for the circumference of the earth, and the gap formed in the middle must be too small for even ants to climb! Miss Guo seems to have read my mind and said with a smile; "Then let's list the formulas and calculate them!" After a series of calculations, the result we got is actually a third of a meter, about 33 centimeters-not to mention that ants can pass, but with Miss Guo's figure, it is also possible to pass. This result is quite different from my original idea. Teacher Guo finally concluded: "In primary school, we use perceptual thinking to judge things through our own cognition, while in junior high school, we need to learn to use rational thinking and verify through calculation." After listening to Mr. Guo's words, I understood something.
In Mr. Guo's class, all the questions about concentration and itinerary were easily noted down. Before each question, Mr. Guo always summarizes the main points of solving such problems for us, and gives us tips from time to time-"Every question is composed of many simple questions. If you learn the basic questions, you can turn them into a few simple questions and you can solve the answers. " There is also the "cross multiplication" to solve the concentration problem. I haven't heard of any way to open my eyes. During the six hours of study, I benefited a lot.
In Miss Guo's class, laughter is essential. Teacher Guo's humorous cells make us admire-"3 is a wonderful number in mathematics." For example, there are three quantities for engineering problems, three quantities for concentration problems and three quantities for travel problems. Isn't there a three in Miss Guo's name? "When Mr. Guo learned that Jiuzhong was also there, his face was full of admiration and his hands raised his fist:" Are you Jiuzhong? "I've heard a lot about you!" It's like seeing the welcome ceremony of the Great Xia in a costume drama, which made me laugh again and again and learned a lot of knowledge in a relaxed environment.
In just one day, I swam freely in the ocean of mathematics. Not only did I see many excellent bloggers' solid mathematical basic skills, but also mastered many problem-solving methods. On the day of the May Day short training class, I was tired and happy.
