To say that my favorite class is math. Because of a math class in grade three, I was fascinated by math.
It was a Wednesday in the last semester of Grade Three. It is raining, and the only ray of sunshine in the sky is covered by dark clouds. My mood is as depressed as this damn weather. My mother criticized me because I didn't get 95 points in math the afternoon before.
The bell rings, alas, it's math class again. When I was absent-minded in class, I overheard the topic "1 1 multiplied by 8" that I had heard before in the Olympic math class, and I suddenly got excited.
I immediately raised my hand and said, "1 1 times 8 equals 88. Because 1 1 is multiplied by any number of digits, both ten digits and one digit are this number. "
"good!" My speech was immediately praised by the teacher, "Yes! Great! This is the secret of mathematics, and the results can be obtained in different ways. " The teacher's eyes cast admiring eyes on me, and my heart was filled with joy. I looked at the topic at the back ... huh? How many problems can be solved in different ways? I suddenly felt refreshed and quickly raised my hand and said, "Teacher, I found that there are other ways to solve other problems." "Well, tell me about it." After listening to my words, the teacher happily encouraged me to speak my mind boldly.
"For example, 12 times 7 equals 84, 2 times 7 equals 14, 1 removes ten digits and then 10 times 7 plus 10 equals 80. Eighty plus four equals eighty-four You can also calculate this. 1 1 multiplied by 7 equals 77. Isn't it easy to calculate? Then 77 plus 1 7 equals 77 plus 7 equals 84. "
The teacher said, "Yes, the small head is quite useful!" " But what did you learn from this incident? "
"The same result, different processes, may be the harvest of my class!" I said.
"Well," the teacher sighed, "not bad!"
"Ding" is over, but I am still immersed in the excitement of solving the problem.
It was that math class that made me interested in math. It not only let me know that there are many solutions to a math problem, but also gave me an inspiration: if you do the same thing and think more about some methods, the result will be more exciting.
The ringing of "Ding Lingling" ended the ten-minute noise, and we will face another century (40 minutes in class). Everyone sat listlessly in their seats, sighing. "Oh, it's math class again!" Before the teacher came, I took out my exercise book and dozed off in my seat. The teacher came slowly and drew some function images on the blackboard. After the greeting, the class officially began.
First, the teacher asked two students to answer the questions on the blackboard. Then he left a more complicated question for the students to discuss. All of a sudden, discussing math problems has become a beautiful landscape in my class. In groups of several students, the discussion may be fierce. "No, I think ..." "No, it should be ...". You see, the "math generals" and "rap generals" in our class beat you to death. He stared at the big round eyes like table tennis, his hands rested on his hips, like an angry elephant and a red-faced Guan Gong. Another classmate, whose eyebrows are wrinkled tightly like willow leaves, can hang a kettle for boiling water. Suddenly, the indoor temperature suddenly rose 140 ... People who don't know the inside story thought that "World War III" was about to break out, and then look at the audience's reaction: "I want to go to the two wars first."
Soon, the teacher announced the answer, which surprised everyone. Everyone didn't expect the answer to be like this, and the two people who had argued before had to admit that they were candidly admit defeat. Next, the teacher introduced several functions. Because there are many and complicated images, the teacher taught us several sets of formulas to facilitate our memory. The formula is very interesting, many students are amused, some students who have no spirit are no longer so depressed, and the classroom is full of laughter. And the class is not chaotic at all. I also participated in it, and continued to answer the teacher's questions, which gained a lot.
Before that day, I didn't expect such a positive and harmonious class in a math class, which really surprised me. The classroom will be very attractive. It turns out that a teacher can be a successful conductor and dance his own personality in class. Students are the best audience, and they echo each other from afar.
Because of this, I can enjoy such a wonderful math class.
