Teacher: Please think of a number. After a series of operations of addition, subtraction, multiplication and division, tell me the operation process and results, and I can guess what number you think of and see which one you think of first.

Student: Multiply a number by 3, add 7, subtract 9, and then subtract the number you want. The result is 10.

Teacher: The number you want is 6.

2. Information games.

Before class: divide the students into several groups, and then you say a word to the first student in each group, and whisper it so that the other students can't hear you. Then let those students talk about the second one. Pass it to the end and see which group does the best! Then put the words from the first group to the last group together and say them. Of course, those groups of words together form an unfamiliar poem or prose. ) Let's see what happens in the end.

Rules:

Everyone has only one chance to tell the next person what he said (it can be changed according to the difficulty). Don't do actions, that is, body language As soon as the students in front say it, the students behind close their eyes and can't open them until the students in front say hello. So as not to look at each other's mouths!

3. Follow instructions and react quickly. From slow teaching to fast teaching, the difficulty gradually increases, and finally the students who make mistakes are eliminated, and the first place will soon be decided with a little reward. The advantage of this game is the integration of body and mind, which not only exercises students' reaction ability and quick reaction ability, but also exercises in a limited space.

4. Anti-password. The teacher said "big watermelon" and the students said "big watermelon", but when they hold their hands, they make small watermelon movements. The teacher said "stand" and said "sit". On the contrary, the teacher said "sit down" and the students stood up.

5. Teach me how to be a teacher while talking. Please touch your right ear. (To the students) Let me touch your right ear. (To the teacher) Please touch your left ear. (to students) I'll touch your left ear ... Please clap your hands with me. I will clap my hands with you. ); Please stamp your feet with me, (I will stamp my feet with you); Please bend down with me, (just bend down with you); Please nod with me, (I will nod with you); Please sit with me, (I will sit with you).

6. In the process of teaching "the basic nature of fractions", I created such a situation that students can learn this abstract knowledge in a pleasant and tense atmosphere. Just after class, I told my classmates a story of "monkeys sharing cakes": the little monkeys on Monkey Mountain like to eat cakes made by the Monkey King. One day, the Monkey King made three cakes of the same size. First, he divided the first cake into four pieces and gave it to the monkey (1) 1. Monkey (2) saw it and said, "It's too little. I want two pieces." The Monkey King divided the second cake into eight pieces and gave him two pieces. Monkey (3) is more greedy and says, "I want 3 pieces". The Monkey King took out the third cake, divided it into 12 pieces on average, and gave him 3 pieces. Children, do you know which monkey eats a lot? After a while, the students all said, "Just as much." So, I asked, "Do you want to know how the clever the Monkey King meets the requirements of the little monkey and gets a fair share?" Just as the students were absorbed in the story and puzzled, I said, "The basic nature of academic scores will be known!" " "Under the best psychological state of students, new courses are naturally introduced, so that students can transfer to the next stage of study with strong interest. Here, questions make students curious, and curiosity turns students into strong thirst for knowledge and strong interest in learning.

7, pointing "game. Taking human's five senses as the pointing object, the teacher reported the name of one of the organs, and the students quickly pointed to where. As the speed increases, your attention must be highly focused. I tried this game once, and my classmates liked it very much. Sometimes they often point their eyebrows at their eyes and make jokes before they have time. In casual laughter, how many psychological barriers have been eliminated. Unconsciously, students relaxed their vigilance and naturally let us introduce into the classroom. 8. "Sit in the Right Position"

The game is simple, but the effect is good. That is, teachers make various cards according to the requirements before class and send them to students for use in class. For example, I sent a card to every student in the class before the review class for the initial understanding of positive and negative numbers. There is a number on the card, including 0, (-1) to (-20) and 1 to 20. When I call a certain number, I ask the students to hold it. Such as "the reciprocal of+1", "the reciprocal of 3", "the number less than-10" and "the number that is neither positive nor negative" ... The students are very active and the classroom atmosphere is active. More importantly, most students have mastered the basic concepts related to positive numbers and negative numbers.

9. "Climb the peak forever"

This game is more suitable for boring calculation teaching. Stick cards on both sides of the "mountain peak" high into the sky, and choose two teams as "climbers" to advance to the peak from both sides respectively. All the other students are judges. If the team answers a question correctly, it will plant a red flag to show that it has advanced several meters. If the team reaches the top first, it will be rewarded. In the competition, the contestants are as tenacious and brave as mountaineers, and the referee silently works out the answer first so as to make a correct judgment. All the students completed their learning tasks happily in the game, avoiding boring calculation learning. In fact, there are many changes in this game, such as "step by step to zero", which means that students can make the final result as close to zero as possible through calculation. Students' interest in calculation suddenly doubled, and the learning effect naturally came.

10, "Poker Magic"

Poker is a game tool that students often use, and students are more willing to accept it as a prop for math learning. When adding and subtracting positive and negative numbers, I use playing cards to let students train their positive and negative operation ability through games. Red is positive and black is negative. Show two cards at random to make up positive and negative numbers. In class, the students are very active and raise their hands to answer. I didn't expect a small deck of playing cards to have such great magic, which is also the magic of math games. I am sincerely happy to see my classmates having fun and learning solidly. Playing cards can be used for many purposes, such as designing a blackjack game with mixed operation of rational numbers. This kind of teaching has achieved the effect of getting twice the result with half the effort and enjoying it.

1 1. Everyone should stand next to Du's seat, and then look at the place where there is a piece of paper blocking the words "endless learning" on the podium table to see what they see. Fu Jianhua looked at it first. He only saw half of the words "nothing learned" and "stop". The next one is Zhang Ruizi, who only saw the words "endless learning". The last one is Li Shuo, who saw the word "endless learning". The ultimate goal of this experiment is to make everyone understand the characteristics of observation: the higher something is, the more objects you see.

12, at first, the teacher read the numbers from 3 to 5. The students recited it once and raised their hands to recite it. When the teacher reads the numbers 6 to 9, the students recite and stand up and recite.

13, situation A teacher who borrowed a class stood in front of a strange class. There was no more time for him to get familiar with the class, only five minutes were left for him.

How to let the topic enter the students at the first time and shorten the psychological distance caused by the unfamiliarity between teachers and students?

We have asked countless times and tried thousands of times, but we always feel that there is a distance between us and our students. At the end of the mountain, we might as well step out of the deep thinking on this issue for a while and listen to how the famous teachers made the opening remarks. Maybe I will be inspired a little and find some answers. Maybe I will have a bright future.

Character: Yu Yongzheng

Style: simple but not simple

Classic clip:

Teacher: Hello, children. Nice to meet you. Do you know me?

Health: No.

Teacher: Then I have to introduce myself. (Teacher: Yu Yongzheng) What should you call me?

Student: Teacher Yu.

Health: Grandpa Yu.

Teacher: What else can I call it? (Life is silent, the teacher calls the name) Who dares to call my name?

Health: Yu Yongzheng.

Teacher: (Stand at attention) Here you are. Who else wants to make a phone call?

Health: (loudly) Yu Yongzheng.

Teacher: (hands clenched) Next. (Laughter).

The teacher concluded: Names are given to people. You can call me Teacher Yu, Grandpa Yu, or call me by my first name. This is not rude, because I am your big friend. You can call it whatever you want.

Comments:

"Simplicity is a realm." After listening to Mr. Yu Yongzheng's class, the first impression is: This kind of prologue is really simple, isn't it just asking students to "call their names whatever they want"? Listening to the language is also very simple. It seems that every teacher usually says so. Come to think of it, it's not like this. What our teacher usually says is mostly after class. As soon as they arrive at the classroom, "teaching dignity" immediately plays the role of "judge" and "preacher" Teacher Yu Yongzheng really put the equal relationship between "you and me" advocated by the new curriculum into the classroom.

The starting time is short, but the goal is very intimate: to be friends with students sincerely; The design is simple, but the function is unusual. One is "stand at attention" and the other is "clench your fist in the next place", which contains respect, trust, encouragement, care and warmth. Self-introduction is very brief, but students deeply feel that learning Chinese is very happy, and students who are teachers are very happy! Simple sculpture is a kind of beauty. 14, character: Dou Guimei

Style: Walking in the sun.

Classic clip:

Teacher: When we meet for the first time, I will give you a gift-three sentences.

The first sentence: "I am great!" (to oneself)

The second sentence: "I am really great!" Give it to your other half, too. Put your hand on your partner's shoulder.

The third sentence: "We are really great!" (Let's say it out loud)

(winning streak said that the class suddenly became active. )

Teacher: We also send this sentence to the teacher: "You are great, you are really great, you are really great!" "

(Sheng Qi says, and the teacher applauds. )

Teacher: The teacher applauded you. What do you understand?

Health: It's glorious!

Health: It's very warm!

Teacher: Did you find the feeling? How does it feel? The warm feeling is great. Let's walk into the text with this feeling.

Comments: "Gifts", we have seen many teachers give students gifts-"Big Apple", "Little Red Flower" and "Thumb" ... Flowers will wither, apples will rot and thumbs will forget. And what Mr. Dou Guimei gave the students, I believe the students will always cherish in their hearts. Because this is what they need most in their studies, and it is a very precious thing in a person's life, and that is self-confidence. "I am great!" "I'm really great!" "We are really great!" "You are really, really great!" Sunshine and rain moisten the hearts of teachers and students. This precious gift makes students feel that sharing happiness and encouragement means sharing life and happiness. Teacher Dou Guimei is not in class, but laying the foundation for students' lives.

Conclusion We selected four famous teachers and read their opening remarks, which made us strongly feel such a word: love! If you love transparently, you will show humor, wisdom, atmosphere and sunshine. Although we understand, we must know how to pay. In those short five minutes, I tried my best!

15, special teacher: Sun Shuangjin.

Preface: respect students and mobilize learning subjects.

Teacher Sun's opening remarks to students at the beginning of the class:

"Classmates, Confucius, an ancient educator in China, once said that in a threesome, there must be a teacher. In other words, one of the three people will definitely surpass me in some way, so this person is my teacher. Today, in this class, Mr. Sun wants you to be Mr. Sun's teachers. Do you agree or disagree? Please raise your hand if you agree! " The atmosphere in the classroom came alive and all the students raised their hands.

But at this moment, Teacher Sun changed the subject and said, "It's not easy to be Teacher Sun's teacher!" The students sitting below looked at each other, wondering what medicine Mr. Sun Shuangjin was selling in the gourd, and they put their hands down one after another.

Then Mr. Sun said, "Because Mr. Sun is older than you and has more knowledge and life experience than you, what must you do to be Mr. Sun's teacher?" Especially in this class. "

Some students honestly replied: "You must listen to Teacher Sun carefully in class."

Teacher Sun smiled and replied, "So, you still can't be Teacher Sun!" "

At this time, another student unexpectedly replied: "We must concentrate on this class. If we can point out the mistakes in Sun's lectures and ask questions that Sun can't answer, then we are Sun's teachers. " (Note: The following teachers all applauded)

Teacher Sun praised him in time and said, "This classmate speaks very well. As long as you can ask questions that Teacher Sun can't answer in this class, you are Teacher Sun's teachers. "

Theoretical docking: Teacher Sun's unique opening remarks, through hints, encouragement and other means, suddenly narrowed the psychological distance between teachers and students, and placed the traditional unequal teacher-student relationship in an equal and friendly relationship. From the psychological point of view, students have regarded the teacher as "one of their own" or have regarded the teacher as a friend. Under such a new relationship, students will get rid of their vigilance against teachers, and they will tell their teachers everything they think, feel and say without reservation. In this way, teachers can not only understand students' real thoughts, but also accurately grasp the weak links in teaching, which provides favorable conditions for teaching students in accordance with their aptitude and creates a relaxed and harmonious classroom atmosphere. Facts have proved that such an atmosphere is of great benefit to cultivating students' innovative spirit, innovative consciousness and innovative ability.

16, let's have a digital relay, for example, all are odd numbers. If the first student says 1, the second student has to say 3, the first student says 1 1, and the second student has to say 13, so that they can all say numbers that are multiples of 3, for example, the first student says 3. Then the second classmate will say 18 and so on. If it is difficult, say multiples of 7, multiples of 9 and so on. This method can cultivate students' quick response and digital consciousness in teaching.

17, the teacher reported one and the students gave two high-fives. The teacher reported two and the students gave three high-fives. Analogy in turn
