Mathematics Weekly 1 Everyone says that "teachers are engineers of the human soul." I think my teacher is no exception. In my primary school life, many teachers have taught us, no matter what kind of teachers are good teachers, we are also very lucky: burly Chinese teachers, serious and beautiful math teachers, dedicated English teachers, humorous and lovely art teachers ... this is an unusual morning. I came to school and collected all the homework sent by the group leader. I took them to a place I have been to many times-President Dong's office. But this time is different. I paid attention to everything in the principal's office. I saw a "Oral Calculations Workbook" on President Dong's desk. The word "East" is written on the cover. I think it belongs to President Dong. Curiously, I opened the "oral arithmetic workbook" and found that the answers written in red ink had been turned over many pages. At that time, Mr. Dong asked us to practice oral arithmetic, and President Dong wrote wherever we did, and she corrected every question carefully. I put the "oral arithmetic exercise book" back in its original place, thinking about something ... every time the teacher asks me to help her make a book or exercise book for teaching, I can see the topics and circles written in red ink. As the principal, Teacher Dong is also a good math teacher. She usually has too many tasks to do, but she still finds time to do the oral calculation exercise books, either by herself or by correcting our oral calculation exercise books. No matter what kind of idea, we should feel admired and ashamed. Still doing math homework so seriously, that's what we have to do. Look at what the teacher wrote and think about ourselves. How can such a good teacher not be loved?
Math Weekly 2 It will be sunny on Wednesday, May 20th.
This summer, I renovated the house. The building area of the house is 102㎡, and my mother told me that the floor area is 0.75 of the building area, so the floor area of my house is 102χ0.75 = 76.5㎡ ... The specifications of the floor tiles I bought at home are 80cmχ80cmχ80cm = 6400 square cm. Theoretically, my family should buy 765000 ÷ 6400 =119.5 tiles. Considering that the corners need to be broken, our family bought 125 tiles, each 95 yuan.
Chapter 3 of Mathematics Weekly These days, I feel very depressed because I did badly in this math exam.
I am anxiously waiting for the exam results. Finally, the test paper was handed out and my heart was pounding. The test paper was handed out. I looked at it and said, "Oh, my God, 62 points!" " I almost fainted because of this terrible number. "Is this my test paper?" I said with a grain of salt. I secretly hid that shameful test paper for fear of being seen. I looked at Mr. Yin's serious face and bowed my head shyly. Then, Teacher Yin explained each topic to us. I adjusted my mind and listened carefully to every topic.
The teacher assigned homework, and the math homework was to ask parents to sign the test paper and then correct the wrong questions on the test paper.
When I got home, I finished my Chinese homework first and corrected my mistakes. After finishing these two homework, I felt a little scared. After dinner, I took the test paper to my mother. Suddenly, my heart is beating fast. After reading it carefully, my mother pulled me and asked me, "The topic is not difficult. Why did you only get 62 points this time? " My mother asked me so that I was speechless. I had to lower my head, but I always felt a little like crying. I said to myself, cry if you want, and it will be more comfortable to cry! I can't help crying. But my mother didn't say anything about me, just said to me, "It doesn't matter, I didn't do it well this time, there will be another time!" " They all encouraged me. I finally stopped crying and smiled. My mother said, "Yes, girls have to laugh to look good!" " "I think my mother is right. I read the test paper again. I found that the reason for losing points was carelessness. I must correct this bad habit!
Yes, I failed in an exam once. Next time, I made up my mind to do well in the next math exam. Of course, I have to do well in every exam, no matter what the topic is.
Mathematics Weekly 4 Today, my mother gave me a question 3ⅹ3=? I snickered to myself, thinking that my mother had studied for so many years before! I can't believe I asked such a childish question. So I answered absently: "3ⅹ3=9." Mom asked me 33ⅹ33=? I did some calculations on the draft paper with a pen, and I got 1089. I will answer immediately.
Then my mother asked 333ⅹ333=? I got 1 10889 after a stroke of calculation, so I answered my mother's question again. Mom seemed dissatisfied and asked 3333ⅹ3333=? I suddenly froze. This is because my mother stopped asking, but asked me if I found any patterns. I read every answer carefully and finally understood. It turns out that each number is 9, ten numbers are 8, and the highest number is 1. Each occurrence of 1 3, 1 and 8 in the two factors increases by 1 respectively. I immediately got 1 1 108889 from here. We also know that we can use this law to solve many problems. I immediately told my mother about this rule, and a bright smile appeared on my face.
At this time, I deeply realized that "nothing is difficult in the world, nothing is impossible to a willing mind". This realizes that as long as we observe carefully, nothing will baffle us.
In mathematics teaching, we realize that students who can actively participate in the process of acquiring knowledge have a strong interest in mathematics and a strong desire for knowledge, and their mathematics quality will develop rapidly. Therefore, mathematics teaching must start with changing students' learning attitude and emotion, so that students can change from mechanical and passive learning to creative and active learning. Interest is the motive force of children's creativity and curiosity. As long as children are interested in something, they will pursue it endlessly, practice it and develop it.
However, driven by the long-term exam-oriented education, we sometimes think that as long as the answers to the exercises are correct and the students remember them, the exam will be fine. So in class, once students make mistakes in their answers, it is difficult for us to keep calm and we can't help scolding them. Over time, the classroom is dull and the atmosphere is dull. More students "hit a wall", so they are no longer willing to take the initiative to participate in the classroom, and their interest in learning mathematics is gone.
1, carefully protect students' interest in learning mathematics.
Timidity and excessive self-criticism are the most dangerous enemies that hinder creation, while courage and self-confidence are the most important characteristics of creative personality. In teaching, teachers should first change their ideas and participate in students' learning activities in the roles of organizer, guide and participant, thus creating a relaxed and harmonious classroom atmosphere and giving students a sense of psychological security. Teachers should fully respect and trust students, regard them as active explorers of knowledge, create a harmonious atmosphere, help students build up self-confidence and promote their active learning. I think caring for students means improving their interest, confidence and efficiency. Therefore, in teaching, I try to respect students' different opinions, tolerate students' wrong ideas and encourage students' creativity. Encourage them to think independently, be good at evaluating students correctly with appreciation, give priority to praise and encouragement, and let students sit in the spring breeze and bathe in the spring rain. "Teaching is no small matter", a casual remark and a casual look in the classroom will directly affect students' psychology. Give praise and encouragement to students who can successfully complete the training. The joy of success makes students more confident. For those students who encounter difficulties in training, we should not choose to criticize, not to discourage them, but to inspire them.
2. Use "environment" to cultivate students' interest in learning mathematics.
Weekly Reflection on Mathematics Teaching (Fine Edition) Weekly Reflection on Mathematics Teaching (Fine Edition) As we all know, many children find mathematics boring because of exam-oriented education. When it comes to math class, it seems to be endless calculation. In fact, mathematics should be the most interesting science that attracts students in primary school. Because it is not only instrumental, but also humanistic and closely related to real life. In teaching, I use various means flexibly, such as body language, courseware, audio and video recording, stick figure, story performance and so on, to reproduce the teaching content. Guiding students to appreciate the environment has achieved good teaching results. For example, in the teaching of "the invariable nature of business" and "regional and regional units", with the help of teaching courseware, I introduce new lessons with vivid stories and interesting games, and children review old knowledge and produce new problems while entertaining, and then they actively carry out inquiry learning. Teachers and students naturally find their own roles, and their learning efficiency is very high.
3. Stimulate the interest in learning mathematics with "demonstration"
Every student is a different individual, and a thousand readers have a dream of red mansions in their hearts. Our teachers should not use the majesty of "egoism" to suppress students' learning enthusiasm and initiative. Instead, we should create a relaxed learning environment for students to debate and express their opinions, and find the embodiment of self-worth in the debate, so as to stimulate their internal motivation for learning and cultivate the spirit of pioneering and innovation.
In teaching, I pay attention to seize the opportunity, light the "fuse" of the debate in time, give students some opportunities to express themselves as much as possible, and do my duty as a guide. If the teaching divisor is the division of two digits, simply calculate the problem of 1200÷500, and I will let the students try to do it in their own books first. Because of the invariance of quotient, there is no problem with the calculation method, so the students are full of interest and confidence. After that, organize classmates to exchange the results: "Quotient 2 is greater than 2" and "Wrong! There was a riot in class 200 for more than 2 minutes, and most students agreed with the first answer. At this time, I asked the students to discuss, and both sides expounded their views and could ask each other questions. As a result, students from both sides immediately launched a war of words. At first, the students all had their own reasons, but gradually, the students who agreed with the first answer realized that they were wrong and were convinced of the rebuttal. In this process, it is entirely the students themselves who are discussing and communicating. Facts have proved that the learning effect is excellent. Because they are actively learning, the embodiment of self-worth is waiting for them. Therefore, encouraging debate is an inherent need to stimulate students' interest in learning. Learning motivation can be transferred. In reality, students who are tired of learning are often interested in sports activities, productive labor and extracurricular activities. We should make the best use of the situation according to different people, and link the motivation of participating in various extracurricular activities with learning mathematics to stimulate students' interest in learning, so that our teaching will get twice the result with half the effort.
Chapter 6 of Mathematics Weekly In our life, mathematics is everywhere.
Don't believe it? What happened today proves this point. In the afternoon, my mother gave me twenty yuan to buy a bottle of soy sauce and a bottle of honey in the supermarket. After arriving at the supermarket, I first chose a bottle of "Douheng" brand soy sauce, 4.40 yuan. Then, I go to buy honey. There are only two kinds of money. The first one is 8.60 yuan, and the other is only 8.40 yuan. I thought, "the hexagon of the first type and the four corners of soy sauce can make up one yuan, which is easier to calculate." Moreover, the first one is two cents more expensive than the second one, indicating that the quality is also good. " So, I picked up the first kind of honey and soy sauce, paid the money at the cashier's desk, and went home happily with the recovered 7 yuan money. In the evening, my friend invited me to go skating, and I readily agreed. I thought, "I'm going to bring chocolate today, and everyone will share it." How much should I bring? I thought about it and brought twelve. If there are two, 12÷2=6, which can be divided equally; If there are three people, 12÷3=4, we can get an average score ... According to this calculation, 1, 2, 3, 4, 6 and 12 children can get an average score. So, I took twelve chocolates to go skating. Sure enough, three people came. I gave each of them four chocolates and just finished eating them.
There is a lot of mathematics knowledge in life, which can't be learned by careless students!
Mathematics Weekly 7 Many students are afraid to take the Olympic math class, because a series of Olympic math problems will make people dizzy. But I have a soft spot for it and feel that "the scenery here is unique." The usual teacher is monotonous and boring. Every lesson in Olympic Mathematics brings me a sense of freshness, which makes me learn a lot of knowledge that I can't learn in class. Many thinking problems that are usually difficult to solve can be solved here.
Today's class made me feel the joy of learning again. The teacher taught us to solve problems with the method of "chicken and rabbit in the same cage", and one of the questions was written like this:
Three cows and eight sheep eat grass. 5 kg; 8 cows and 23 sheep eat grass a day 1 17. 5 kilograms. If Yi eats three times as much grass as a sheep, how many kilograms does a sheep eat?
The teacher asked, "Who can solve this problem?" I raised my hand, but the teacher didn't notice, so I explained myself: "In fact, this question is quite simple. We eat grass from three cows and eight sheep a day. 5 kg, it is known that you can eat 3×3 cows and 8×3 sheep a day ... "There are four steps in the teacher's answer, and I only used three. After the teacher finished speaking, I said, "Teacher, I can solve the problem in only three steps." The teacher said, "Then tell me about your solution." I said, "The illness says that Yi eats three times as much grass as a sheep. After I convert cattle into sheep, three sheep are converted into 3×3 sheep, and one * * * has 9+8= 17 sheep. The total amount of grass eaten by three cows and eight sheep in a day is 42. 5÷ 17=2。 5 kg, found out that each sheep eats grass every day 2. 5 kilograms. " The teacher smiled and said, "Yes, An Ting's method of solving problems is called method of substitution, which makes solving problems very simple. Everyone should learn from her in the future, and don't just be satisfied with a solution. " I was flattered by the praise.
I study, I am happy, and the "scenery" here is really strange. Students, let's enjoy it together!
In daily life, we often need mathematics to help us solve problems, which shows the convenience and practicality that mathematics brings us. Although mathematics can bring us benefits, there is always a lot of controversy behind the benefits. Let me talk about the controversy about my family's different views on decimals.
Once, my family and I went shopping in the supermarket. I see that the prices of goods in supermarkets are almost all a few dollars or a few dollars. There won't be a few dollars and cents at all. So I was curious to ask my father why. Dad said: "If there are two or more decimal places after the decimal point, it will cause a lot of inconvenience to everyone, so others will pay for the integer or the number after the decimal point." Upon hearing this, my father nodded thoughtfully. But my cousin jumped out and said, "No, our teacher said: the prices in the supermarket are different, even if they are similar, what I saw in the supermarket is still a row of items with prices above two decimal places!" " "What my cousin said is true, because I went with him. This is really reasonable, and the old woman is right! Well, I had no choice but to go to the assistant's aunt, who said, "In this supermarket, we always pay in approximate figures. Generally supermarkets are like this, unless some supermarkets have special circumstances!
Pay attention to everything in life and you will find many beautiful things!
Math Weekly 9 Today is Saturday, June 65438+1October 65438+May. My father and I went shopping in South Street.
At 8 o'clock in the morning, we arrived at South Street by bus. There happened to be an old man beside the platform, and there was a talking scale beside him. Seeing me coming, grandpa smiled and said, "Little friend, do you weigh yourself?" I asked a little curiously, "How much does it cost to weigh it once?" Grandpa replied cheerfully: "You can only weigh 1 yuan at a time, and you can also measure your birth height!"
I thought to myself: this is really killing two birds with one stone!
So I stood firm on the scale. Grandpa turned on the switch and only felt something soft touch my head. Then, a small rectangular note is printed on the machine, which reads: "Weight: 27.0 kg, height 132.5 cm"! This half year is 4 cm taller, but what about the weight?
At this time, I remembered what the math teacher said, "kilogram has a name." I didn't expect to meet it today, and I know that my weight has increased by 2 kilograms! "
I was so happy on the way back! I must exercise my body!

Weekly Practice of Financial Mathematics (3)
I was assigned to work in the marketing department, mainly studying with Xx. I introduce my internship from the following aspects;
The first thing is to go to work at nine o'clock every day. If you arrive early, you can read securities, newspapers and magazines in the lobby of the company. Understand the national macroeconomic policies, financial news, the latest information in the securities market, such as information disclosure of listed companies and other announcements, mainly analyze market hotspots and watch some stock reviews.
The next step is to start the basic work of the day.
Organize customer information, including account opening application, account opening contract, bank-securities exchange application and customer information change form. And copies of customer ID cards, bank cards, shareholder code cards, etc. , related work generally includes the following three aspects:
1, sort out relevant customer information, and check all documents generated by the business on that day in time to ensure completeness, accuracy and no omissions. If there are omissions, they must be corrected in time. Please report any major discrepancy. For a long time, we have been particularly sensitive to documents and are always afraid of any mistakes.
2. Put the sorted customer data into the customer's portfolio in order. Then go back to the filing cabinet.
3. When we have time, scan the natural person registration form, copy of ID card and account opening text generated on the same day into the directories of various business entities, and then send them to the headquarters in a unified way.
Finishing customer information takes up a certain amount of work in the internship, which is a simple but quite complicated process, requiring care and patience; The orderly arrangement of customer information files is to find it conveniently and quickly in the future, so the staff gave us serious guidance and scanned the account opening text. The unscanned documents of the new account and the previous account shall be uniformly scanned and saved in electronic form.
This internship has made great progress in both knowledge consolidation and experience accumulation. In the Wang Yang sea of the securities market, individuals can only succeed if they are constantly honed until they are mature. Although the internship is only two months, it has benefited me a lot. In this internship, the college won this rare internship opportunity for us. Only with their efforts can we successfully complete this internship. In the future, we need to find opportunities to constantly exercise ourselves and accumulate experience to lay the foundation for future work in this field.

During my short two months as an intern in xx County Branch of ICBC, my thoughts have changed greatly. When I used to learn knowledge at school, the teacher always filled my mind with knowledge. I don't have such a strong thirst for knowledge at all, I'm just forced to learn. But my internship here really makes me feel great, my knowledge is poor, and the learning atmosphere of bank employees is particularly strong, which invisibly creates my own desire to learn. Everyone here is taking the time to study, which makes me especially admire. Give me a feeling that I really want to blend in with them. This will greatly promote my future life.
Only by persisting in learning new knowledge can we improve ourselves more, and there is such an atmosphere here. At the same time, this internship also provided me with unique learning methods and opportunities, which made me change from traditional passive teaching to active learning; Get rid of the rote learning mode and learn by doing instead, which enhances the ability of understanding, innovation and reasoning. I have mastered the methods of self-study, and the improvement of these methods will benefit me for life. I think these rare two months have really made me understand the basic laws of work and study.
Weekly Exercises of Financial Mathematics (5)
During my internship in the finance office, I mainly studied the comprehensive business processing system, became familiar with the accounting subjects of banks, basically mastered the bookkeeping and rechecking operations of the system, and was able to independently handle remittance, securities clearing and foreign exchange accounting in the same city. Through reading, asking questions and hands-on operation, I have a systematic understanding of the main work of the finance office, especially the check draft. Before my internship, I only learned its basic concept from books, but I didn't know the real bill specifically. Now I have a general understanding of the process of ticket inspection and payment. During my internship in the international department, I learned while doing, and found that most of my knowledge was learned in international settlement. What I have to do is to be familiar with all kinds of bills, master their functions in international trade, and help and guide customers to fill in and review bills. With the help of teaching leaders, bank employees and their own efforts, I feel that I have benefited a lot.
This internship brought me from pure theoretical study in school to practical learning environment. As soon as I entered my post, I realized that it was time to restrain the wildness of my school days. In a word, this internship has integrated all aspects of knowledge for me and paved the way for my future work and life. I think this change is a qualitative leap.
