On the way home from school, I asked my father, "Why should we study math?" What role does mathematics play in life? Dad said loudly: "the role of mathematics can be great!" For example, the RMB we use has numbers on it, and ... I know there are clocks, telephones and calendars. Now I finally know how important numbers are! Ha ha! We laughed happily.
I remember once, my father's company organized a trip to the park and visited the park. The doorplate reads "individual ticket to 5 yuan, 10 group ticket to 30 yuan. You can get a 10% discount if you buy more than five group tickets. There are 37 of us. How can we get the best deal? My mother asked me: "Of course, it is cost-effective to buy a group ticket! "! Individual tickets for each 5 yuan, group tickets for each 3 yuan! We can buy three group tickets and seven individual tickets! Mom said, "No! It is more cost-effective to buy 4 group tickets, only 30× 4 = 120 yuan! And yours will be 3× 30 ~ 5× 7 = 125 yuan! Dad said. I had a brainwave and said, "We can invite several other tourists to buy tickets together!" 30× 5× 9/10 ~ 3×13× 9/10 ≈100 yuan. "Yes!" Dad invited 13 tourists to buy tickets together. Play happily in the park.
On another occasion, our family baked cakes together, each with three pieces. "Dad, how long will it take us to bake three cakes at least?" ? Each cake needs to be baked for 2 minutes. "Dad said proudly," six minutes, of course! This is not difficult for me! "Really?" Mom said, "It should be 3 minutes!" How is that possible? 2× 3 = 6 points. "I shouted." Don't believe me, I'll show you! "I saw my mother bake two cakes for one minute, then the third and first cakes 1 minute, and finally the second and third cakes 1 minute." All right, it's done! Mother cheered loudly, and I saw three golden cakes in front of our eyes. I can't help drooling. I took one. Wow! "delicious! We shouted. The three of us are immersed in the ocean of joy.
After these things, I love math even more. Mathematics is everywhere in my life. As long as you find and feel mathematics with your heart, the happiness of mathematics will be displayed in front of your eyes!
Fourth grade of Nanjing mechanics primary school: children
The second week of the first week of mathematics
According to the arrangement of the practice school, I started a week's class and arranged the class schedules of all math teachers. I'm going to listen to the teacher's class as much as possible without touching it. On the one hand, I want to learn different things from different teachers, on the other hand, I want to get in touch with students in different classes and get to know their classes.
After a week of observation and detailed records, I really learned a lot. Every teacher has his own teaching methods, including body language, which is very attractive. Some of them infiltrate new knowledge in their lectures, while others treat students in a traditional way. Students of different grades have different performances in class. When I sit at the back of the classroom, I am sometimes moved by their words and deeds. Gradually, the children became familiar with my teacher, and even habitually liked a teacher to pay attention to himself behind his back.
Second week
How time flies. It's the weekend in a blink of an eye. Think about the first day when I came to the internship school. I am so strange to everything, and I know that primary education is very different from the previous middle school internship, but I am still very excited about the next internship.
The internship school received me, showed me around the teaching environment, briefly introduced the school, and introduced my tutor, Mr. Zhang, and several other math teachers to me. Every teacher, including the janitor, expressed great enthusiasm for the arrival of my intern, which made me feel very cordial. Students' activities during recess and entertainment activities on the playground seem to bring me back to primary school. That scene, like the dancing notes of youth, kept beating, but at the same time it was serious and lively. At that moment, I liked it here more, like the students here, and like the profession of teachers.
Third week
After last week's teaching stage, this week will officially enter the classroom and carry out the actual combat stage. After the trial teaching began, my daily job was to listen to excellent math teachers, write lesson plans, try teaching, revise the trial teaching, and practice and improve repeatedly. Until you practice what you want to say in a class, until you know it by heart Even so, when I went deep into the classroom for the first time, I still encountered many problems that I hadn't learned in normal schools and didn't expect in advance.
After all, my mentality when I try to teach is very different from that when I take a formal class. My tutor, Mr. Zhang, will seriously comment and analyze the results of my efforts, which also makes me more confident and curious. Under the guidance of the teacher, I understand that preparing lessons, preparing myself and preparing students is very important for a good class, and the efforts and requirements required for a short 45-minute class are endless.
Fourth week
From the moment I entered the school, the internship school gave me a warm and enthusiastic feeling. All the teachers didn't regard me as a student, but regarded me as one of their teachers. It wasn't long before the internship was invited to the party of the internship school. At the party, I felt the harmony and harmony of the teachers. The teachers are extraordinary and admire their manners. This is a group of respectable and lovely people.
Teacher Zhang took me to introduce the school leaders and other teachers one by one. Although I can't tell them apart at once, the smile of encouragement and attention is clear and profound. Through this gathering, my relationship with the internship school is closer, and I hope that one day I can really become one of them.
Fifth week
In a blink of an eye, I have been practicing for a month. In this month, I still remember everything clearly. I feel that I am slowly adapting to this new life, which is a challenge to my working ability and a test of childlike innocence, hehe! Now there is no tension and anxiety in class, and more attention is paid to development, that is, how to make the class better and give full play to one's abilities.
It should be said that my internship life has been rather tiring since this month, but watching their lovely smiles, listening to them say hello to the teacher and saying goodbye to the teacher made my tired body feel very relaxed. Sometimes those lovely smiling faces often appear in my mind, which makes me eager to see them in class as soon as possible. Maybe this also shows that I am making progress quietly.
Sixth week
Just out of school, I am like a child's big sister. With deep love for children, I often unconsciously regard children as my brothers and sisters and really love them.
I believe that children need love more when they are young. When they left home, the teacher was the only person she trusted. For the lower grades, some children did not adapt to the environment at first, and various situations appeared. I take teacher Zhang as an example and embrace every child with a true and soft heart. Gradually, the children became familiar with me and were willing to come to class. Now, the children have a good relationship with me, and they echo my feelings with their actions. From the mouth of my parents, I also know the children's deep love for math classes and teachers, just like a sentence: Maybe you only give your child one point, but your child will give you ten points, 100% or even more. I'm glad I took the first step.
Seventh week
Every time I start a new topic, I am very happy. I hope to communicate with students in a new way. Facing the current primary school textbooks, I need to study further. In the first few classes, I was not familiar with the teaching materials, which caused the lack of teaching. Therefore, I will seriously and comprehensively analyze and study the teaching of the new curriculum. As the saying goes, to give students a bowl of water, they must have a bucket of water.
I have a deep understanding of this. For example, once I was teaching a little rhythm and the students couldn't sing well. I broke down the duration of each note, but in the end the students still couldn't sing well. Later, I had to ask my tutor how to express it here. It turns out that for primary school students, some knowledge points do not need to be solved too thoroughly. Let the students imitate it. For example, it can imitate cicadas in summer.
Eighth week
For the second-grade class, it seems to be more gamification, and I began to wonder how to teach students theoretical knowledge in an interesting way. In order to prepare for the lesson "Deer", I prepared a fairy tale that children like to import before class. When I told the story in the forest vividly, I saw the children's eyes staring at me intently and turning with my body movements. At that moment, it was never quiet, revealing the innocence of children full of childlike interest.
I also personally made various animal headdresses, which are lifelike. I plan to perform a play at the end of the course. My teaching plan is complete and my thinking is clear, but the operation in class seems to be not so satisfactory. Theory will eventually be put into practice, and the effect of practice is unpredictable!
Ninth week
It is the third month of internship. Now I go in and out of school like a formal math teacher. It should be said that I am satisfied with my internship life, and I am still very full and happy. I am really happy to have a group of students who love me and students I love. School leaders and teachers recognize me and support me.
It feels good to have math class according to the curriculum, listen to other courses, have tea and chat with teachers and principals, and have dinner together when you are free. I think this should be my future career!
Tenth week
First, be serious and responsible, work hard, be a teacher by example, and actively carry out mathematics teaching.
On the third day of my internship, I made a work plan for mathematics teaching, and then I started teaching as planned.
Every day, my daily work includes: First, follow the practice. Go to the playground at 6:25 and 9:30 every morning to urge the students to do exercises seriously, check their gfd and wear school cards. After morning exercises, urge students to clean the clean area and every corner of the classroom; Check the dormitory hygiene and housekeeping; 10:25 Go to the classroom to urge students to do eye exercises. Second, study in the afternoon, get off work, manage discipline, coach individual students and do ideological work for individual students. For example, a girl stays up late and comes home late. After other students reacted to me, I used the time of self-study class to call her out to talk alone, asked why (she forgot the time when chatting with her classmates), and explained to her the stakes of coming home late: first, her safety, and second, it would affect the students who had already rested. From then on, she went to bed late on time every night. The third is to go to the dormitory at 22:30 in the evening to urge students to turn off the lights and go to bed on time.
Through my daily work, I took the initiative to care about students' study and life, and soon became familiar with and mastered the situation and characteristics of classes and students, so that mathematics teaching could be carried out smoothly.
During the period of managing the class, I organized a basketball friendly match, which enhanced the cohesion of the class; And arranged a class meeting with the theme of "career planning in senior high school", which promoted mutual understanding and understanding among students, made clear the goals and made a study plan.
Through unremitting efforts, I have established a good relationship between teachers and students, gained their trust and become the object of their concern. I also sincerely listen to their talk and enlighten them.
Second, under the guidance of teachers, learn with an open mind and improve the teaching level in an all-round way.
Teaching practice is divided into two stages:
The first stage is the probation period. In the first week, we listened carefully to each class of the tutor, recorded the lecture content, studied the tutor's teaching methods, teaching means and thoughts, discussed with the teacher after class, humbly asked for advice, deeply understood the requirements and processes of classroom teaching, learned how to prepare lessons, and prepared students.
The second stage is class. Because I was in the same class as two other interns, I was arranged to attend the third class. Moreover, the long class interval arranged by the tutor also gave me enough time to study the teaching materials and write the teaching plan in detail. I wrote the lesson plan again and again, changed it again and again, until I thought it could better meet the classroom situation. Then you will get the approval of your tutor. Under the guidance of the tutor's corrections and suggestions, make changes, rearrange the teaching plans, and try out the lectures carefully before class. My tutor and partner gave me comments after class, put forward valuable opinions on my shortcomings in class, affirmed some of my advantages, encouraged me to make efforts to correct after class and improve my teaching level to ensure that I would not make the same mistakes in the next teaching process. With such efforts, my teaching attitude, language, writing on the blackboard, questioning skills and interaction with students have all improved.
Looking back on this month, we can see that every intern teacher in the internship group of Lingui Middle School is dedicated, but dedication may not be successful, but it will be perfect. After all, we are still interns, there are still many chapters in the construction of knowledge, and we lack teaching experience. We even miss words in class and do things that make us feel ashamed and ashamed all day. However, during this period of study and practice, we have learned a lot from teachers and teammates, such as the different teaching styles and skills of class teachers.
Our internship is coming to an end, but my pursuit and efforts for teaching will continue, and my care for students will not decrease. As a prospective teacher, I will continue to work hard and grow in my future study, work and life, and strive to become an excellent math teacher.
Grandpa went to buy a case of beer to entertain guests today. In the evening, the guests came. Mom and dad took out melon seeds, peanuts and oranges. They sat together, talking and laughing. Dinner is ready, and we all sit around the table. Some adults drink beer, some drink old wine, and all children drink drinks. Everyone ate with relish. After dinner, the guests left. I found that the box of beer that grandpa bought was packed like this, with 6 bottles in each row and 4 rows. I used the formula "4624" to quickly calculate that the whole case of beer was originally ***24 bottles, and now there are 18 bottles in the case, so the guests always drank 6 bottles of beer. I counted the empty bottles and the result was six.
Math Weekly Article 4 65438+1October 25th is the time for our sixth grade exam. At the moment of the exam, we realized that the subject we got was math. Before the exam, our class teacher and teacher Zhu told us to do the test paper carefully. Teacher Zhu also said, "This paper is not difficult. As long as you do it seriously, you can achieve good results. If you do it well, you must check it! " I think: I'm good at math, too. But success or failure lies in this idea.
After reading it the first time, start writing. I looked at it carefully and went down to answer it seriously. In order to have time to check, I accelerated the time to do the problem. I went on doing one question after another and finished it in a blink of an eye. After I finished, I found many loopholes (wrong questions). After the job is done; When the teacher came to answer the question, he got 97 points and felt a little relieved, but this was not the final score after all.
When I was nervous, it was the first day of vacation after the final exam, because all the scores on that day would be known, and my heart was beating so fast! As soon as my mother's cell phone rang, I knew it was a score. I turned on my mobile phone to read the information, and it was only 93 points. I made two mistakes when I tried to check my score. Why do I only get 93 points now? When I was really discouraged, I began to be happy again when I saw my total score ranked ninth.
On the third day of school, I was afraid to face Mr. Zhu because I failed in the math exam. My mind flashed and I finally knew why I did so badly in the math exam. Because in order to check, but also to speed up the time to do, alas, a long time, sparse and not leak! Strive for the next final exam, that is, the last paper of the school exam. I will do better in the exam, so I will work harder next semester and tell my classmates that you should also cheer next semester! Don't be overtaken by me, come on, yeah!
Chapter 5 of Mathematics Weekly This is my first time to participate in the Olympic Games. I like the Olympics very much and find it very interesting. Doing Olympic math problems is like walking a maze, confused and happy, and I really want to explore what it is. A few days ago, we held the first Olympic Games.
One day, the math teacher said happily, who wants to take part in the Olympic Games? Each applicant pays 100 yuan, so I thought, I'd better not go.
I can still save 100 yuan, but on second thought, I'd better call. In case of misspelling, you can get praise from teachers and classmates, and you can also prove yourself.
There are not many people who sign up in our class, such as me, Yihao Zhang and Zhai Jinzhe. I went home at noon and told my mother about this piece. I said eagerly, after dinner, let's review math together.
The exam is not far away. I review math and do exercises at home, and some of them get sleepy after reviewing.
One Friday morning, the math teacher issued a certificate to all of us who participated in the Olympic math competition, saying that we would arrive at 1 1 tomorrow morning at Class 3, Grade 6.
On Saturday morning, I hurried to school. The teacher opened all the doors of grade six, and my seat was 2 1. After playing for a while, the game began. I looked at the paper and was surprised to think that it was so difficult. I carefully finished the questions in the paper, checked them wholeheartedly and handed them to the teacher.
A few days later, the honor list of the Olympic Games came out. Li Yizhuo was the first to see it, and he came over and told me happily, Lao Cao. You won the prize? Is it? I don't believe it, do I? Run over and have a look, really? I, Cao Zhenyuan, won the third prize, and my excited heart is about to collapse? Don't mention how happy you are.
Thanks to my math teacher, thanks to my efforts, thanks to my efforts, I will learn Olympiad well and win glory for my class.

At noon today, in order to measure the size of chopsticks more accurately, I asked my father to take a slender measuring cylinder from the chemistry room. The scale unit is smaller, and each unit is only 1 cubic centimeter. At this point, I seem to feel victory beckoning to me. I really have everything except hands-on experiments.
First of all, I drew a dividing line on disposable chopsticks with a pencil, divided the chopsticks into two sections evenly, and soaked them in water to avoid washing them when measuring. Then, insert the chopsticks into the measuring cylinder, drop water into the measuring cylinder with a dropper, let the water in the measuring cylinder rise to the dividing line of the chopsticks, take the chopsticks out of the measuring cylinder after recording the water level scale (38 ml), and then record the water level scale (34.5 ml) in the measuring cylinder. The difference between the two water level gauges is the volume of this part of chopsticks, which is 3.5 cubic centimeters. In the same way, I measured the volume of the other part of the chopsticks to be 5 cubic centimeters. When the two measurements are added together, the volume of the chopsticks is 8.5 cubic centimeters. When I got the result, I cried excitedly. How proud and proud I am at this time!
Today, I am very happy to watch my "Intelligent Mathematics" at home. I looked at it and saw an interesting math problem about math on a pair of Spring Festival couplets. The content inside is that the elders of the Yuling tribe lived in the late Han Dynasty, and the Queen of the Magic Kingdom led the courtiers to celebrate their birthdays. When she arrived, the witch Xiaoxing saw the elder's long white beard and couldn't help asking, "How old is the elder?
It's naughty to chew the head of an animal elf. He had already heard about the mathematical ability of the subjects in magic kingdom. He decided to have a look today.
So, he wrote a question in the context of couplets:
Part I: Flowers reopen, plus 37 years.
Bottom line: ancient and rare, once more in spring and autumn.
I didn't know where to start at first, because I didn't know the meaning of the flower and the ancient. Later, my mother said, "Flower armour means sixty years old, and ancient means seventy years old. Now, I finally have a clue. The reopening of the first part is two 60s in the next part, 3×7=2 1 year, 60×2+3×7= 14 1 year in the first part, and two 70s in the second part.
Ah! Mathematics is so interesting.

Today, my father and I went to the bookstore to buy books.
We came to the bookstore. I picked out a long-awaited book and went to the cashier. Dad said, "Your book 12.6 yuan, my book 16.3 yuan, I took three ballpoint pens, 1.5 yuan. How much is left in 50 yuan? If you guess right, the rest of the money can buy you ice cream. " I think: 50 minus 12.6 plus 16.3 plus 1.5 times 3 equals 16.6 yuan. I said, "16.6 yuan." "Well, this 16.6 yuan can buy you an ice cream." Dad said happily
When I arrived at the ice cream shop, my father asked me again, "I bought two ice creams with 1.5 yuan and paid 16.6 yuan. How much is left? " I think: simple, 16.6 minus 1.5 times 2 equals 13.6 yuan. I said, "There is 13.6 yuan left." Dad said, "Not bad! Not bad. " I said angrily, "You underestimate me. This is a topic for two years. If I can't even know these, am I still a fifth-grade student? "
Mathematics is inseparable from life.
