This semester, I took over two new third-grade classes and became a math teacher in 170 1 class and 1709 class. Two days before school starts, I have been thinking about how to have the first class. I accidentally read an article "The First Lesson of a New Math Teacher" written by the official WeChat account "Primary Math Teacher". The author of this paper, Mr. Yi Yang, believes that the "first impression" left by teachers to students is very important for the first class of new teachers. In other words, whether the initial transition of "succession" is smooth depends on whether the students in the class can accept the new teacher. If teachers can be loved and recognized by students soon, the distance between teachers and students will be closer, the communication between home and school will naturally be much smoother and the teaching work will be much easier.

This article, like "timely rain", solved my "urgent need". So, I imitated Mr. Yang and gave such a "chat-style" math class to the third-grade pupils in my own class.

preface

Preview before class, walk into the classroom with a smile and say hello to teachers and classmates.

Teacher: Students, do you know me?

Health: No, (I almost said "I don't know" in unison, and then I said "I know" and "I know" with my little hand)

Teacher: Some students said that they knew me because they came to the school to help clean up two days before the start of school, and they also met me once, right?

All the students who raised their hands nodded their heads.

Teacher: Do you know who I am?

Health 1: I don't know.

Health 2: You are a math teacher.

S3: You are Mr. Luo Zhen.

Teacher: Why did you say I was a math teacher?

Student: Because Zhang, the former math teacher, went to have a baby, Teacher Tan said that he changed his math teacher this year. And this class is a math class. You must be a math teacher!

Teacher: Oh, you are really something! In mathematics, the thinking process you just had is called "reasoning". (Turning around and writing on the blackboard: "Reasoning") "Reasoning" is a very important mathematical thought. You can reason, which shows that you have strong mathematical thinking ability. Students, let's applaud this thoughtful student!

Ask the student's name and shake his hand.

Teacher: Great! You are the first student in this class to be known and remembered by the teacher.

Teacher: Did you just say that I am Teacher Luo? Where did you find it?

Student 1: Your name is written on our schedule.

Student 2: On the first day of school, the math teacher's name was written on the blackboard. It's you. Your phone number is on it. My mother took a picture.

Teacher: Oh? Is it? Have you noticed? (To other students) Being an observant child shows that you must be very careful in your daily life.

Teacher: Did you know this word before? (Write your name "Luo Zhen" on the blackboard and point to the word "Shenzhen") The teacher's surname is Luo, and my word "Shenzhen" is Shenzhen. Do you know why you call me that name?

Health 1: Your father's surname is Luo.

Health 2: Teacher, were you born in Shenzhen?

Teacher: Yes, you are really something! You guessed it at once. It is because the teacher was born in Shenzhen that my father gave me such a name.

Topic extension

Teacher: Does the name your have any special meaning? Have you pinned your parents' expectations and blessings on you? I want to invite some students to talk about it.

Health 1: My name is Yan. When I was a child, it was called Lele, which my father gave me. "Yan" is because my father is surnamed Yan, and our hometown lives in Yanlou, where everyone is surnamed Yan. "Lele" means I want to be happy when I grow up. However, my grandmother thinks the name "Lele" is unlucky. In our village, many children who used to be called "Lele" later drowned. Then, my father changed my name to "Yan" "Yi" means "polite", and "En" is not clear to me.

Teacher: "Well", I think it should be "gratitude". Dad wants you to have a grateful heart. what do you think? (Yan nods, then shakes hands with Yan) Nice to meet you. You are the first child that Teacher Luo officially met in our class. Thanks for sharing. Please sit down!

S2: My name is Zhou Zixuan. My father's surname is Zhou, and "Xuan" stands for day lily, which is purple, so my name is. My parents want me to be as carefree as "day lily".

Teacher: Nice to meet you and shake hands with you. I hope you grow up happily! Ok, let's cheer for Zi Xuan!

Health 3: My name is Yan Ranhui. "Ran" rises like the sun, and "Hui" stands for wisdom.

Teacher: Wise, how wonderful it is that Ran Ran rises like the sun! (Shaking hands with Ran Hui)

Understanding teacher

Teacher: Facing the new teacher, you must all want to know me. What do you want to know about me? You are welcome to ask me questions.

Student 1: How tall are you, teacher?

Teacher: This classmate is the first to raise his hand to ask questions. It often takes a lot of courage to ask questions. Let's applaud his courage!

Encouraged, the students raised their hands and asked me more questions. The questions revolve around height, age, weight, teaching experience, constellation, home address, children and so on.

Health 2: How old are you, teacher?

Student 3: Teacher, did you move from Shenzhen to Changsha?

Student 4: Teacher, which school did you study in when you were a child?

Health 5: When is your birthday?

Health 6: How many years have you been teaching?

Health 7: What sign are you in?

Health 8: Teacher, do you have any children?

Health 9: Teacher, how much do you weigh?

……

Teacher: Everyone is very active. Dare to ask questions is a good learning quality, and being good at asking questions is a special ability. Asking questions to the point will help us better understand the unknown. Now, I choose two of these questions to answer you. The teacher doesn't tell the answer directly, so let's discuss it together.

Measure someone's height

Teacher: A classmate asked me about my height just now. Can you guess my height? (My actual height is 160cm)

Health 1: 1.5 meters.

Teacher: On what basis did you guess?

Health 1: a wild guess.

Teacher: Do you know how many centimeters one and a half meters is written in centimeters?

Health (qi A): 150 cm.

Health 2: My height 135 cm. I found that you are so much taller than me (gesticulating by hand), so you should be 155 cm.

Teacher: Your guess is well founded, not bad!

Teacher: I want to know my exact height. What should I do?

Aggressive answer: quantity!

Teacher: The teacher specially brought a soft ruler today. (Taking out the prepared soft ruler from the pencil box) I'd like to ask two students to come up and measure the teacher's height. A boy and a girl were invited to the stage to help measure their height.

I straightened up and cooperated with the students to make them measure. The students found that the soles of my sports shoes were thick, and they all told me to take off my shoes, so I took them off. While taking off his shoes, he joked, "What should Mr. Luo do if his feet stink?" Scared some students to cover their mouths and noses exaggeratedly. "Ha ha, just kidding! Teacher Luo doesn't have smelly feet, "I said while laughing. "

After taking off my shoes, I stepped on a piece of white paper on the classroom floor. The students stood on tiptoe to measure my height. Other children couldn't hold back their inner curiosity and wanted to know the measurement results at the first time, so they stood up and watched. A little boy sitting in the back row even left his seat and came to see me. After measuring the reading, some students found that the reading on the soft ruler was only 150 cm. Just as the two students on the stage were hesitating, a student under the stage proposed to use a ruler to assist the measurement and measure that paragraph without reading a book. Girls take a soft ruler and lay it flat on the blackboard. Boys measure it and read it, 9 cm. So the total length of the two paragraphs is 150 cm+9 cm = 159 cm. "Teacher Luo, your height 159 cm" "Teacher, you 1 59 m, a little shorter than my mother" ... The students were very excited about the measurement results and expressed many opinions. ...

Teacher: Students, it doesn't really matter what the teacher's actual height is. The important thing is that you have gone through the process of guessing and verifying. I hope that in the future study, you can also make bold guesses and seriously verify as you do today. In the second grade, we already knew the length units "centimeter" and "meter". This semester, we will learn the length units "millimeter", "decimeter" and "kilometer" (Unit 3: Measurement). By then, every student here will experience the whole process of actual measurement. It's as interesting as you measured Mr. Luo's height today. Are you looking forward to it?

Health (answer in chorus): Looking forward to it!

Calculate age

Teacher: A classmate asked Mr. Luo's age just now. The teacher doesn't tell you directly, but wants you to do the math yourself. I was born in August 1992+0 1. How old do you think I am this year?

Students think and set aside time for students to calculate.

Health 1: You are 27 years old.

Follow-up: How did you work it out?

Health 1: I introduce it every year. 1993, teacher 1 year; 1994, 2 years old ... In 2002, the teacher 10 years old; 20 12 years, the teacher is 20 years old; Seven years have passed, so the teacher is 27 years old.

Teacher: Yes, yes, it is also a method. How old are you this year?

A: I am eight years old.

Health 2: This year is 20 19. If you were born in 2000, you are 19 years old. But you were born in 1992, so 19 plus 8 equals 27. So, teacher, you are 27 years old this year.

Teacher: Wow, you used a carefully calculated middle year of 2000. Observing the puzzled expressions of most students, I decided to discuss his problem-solving ideas with the whole class. Students, let's do the math together (the cameras are listed on the blackboard). Let's use 20 19-2000= 19 (year) to calculate how many years from 2000 to this year. Then use 2000- 1992=8 (year), and finally use 19+8=27 (year), and 27 years is 27 years old. You got it? What's your name?

Health 2: My name is Zheng Yuzhou.

Teacher: Nice to meet you. Your thinking is novel and clear. Thank you for your answers. Please sit down!

Health 3: I just worked it out on draft paper. I used 20 19- 1992 to get the result that I am 27 years old. Today is September 2nd, teacher. You have celebrated your 27th birthday.

Teacher: Your calculation ability is really good! We haven't learned the subtraction within 10 thousand, but you already know it. It shows that you not only have strong calculation ability, but also have the consciousness of learning in advance, which is really good! We will learn addition and subtraction within 10 thousand this semester. You can open the catalog of math books. Units 2 and 4 are just right.

Class summary

Teacher: Students, the teacher is very happy today. She made 48 new friends in 170 1 class. Do you know more about me? What kind of teacher am I in your mind? What are your new goals for the new semester? You can think about it after class and communicate with your parents when you get home.
