Mathematics Weekly 1 We have studied equations these days. Through learning, I know that the equation is an equation at first, and it is also an unknown equation. Using the properties of equations, I learned to understand and test equations, and I also used equations to solve problems in my life.
I remember that during the winter vacation, I previewed the equation under the guidance of my mother. At that time, I thought it was very troublesome to solve problems with equations, and I had to set up χ and write solutions. At the same time, my thinking is different from the original, and I feel very incomprehensible. Later, under the teacher's explanation, I finally understood that a good equation can be made by setting an unknown number and finding out the equivalent relationship between the unknown number and the known number.
My mother told me that we are learning simple equations now, and we will learn some complex equations such as binary equations and ternary equations in the future, so we can solve more problems then!
Now I think: it's good to learn equations!
Chapter 2 of Mathematics Weekly My math homework was torn twice!
When I came home from school, my mother copied the math paper for me. When I got home, I had a rest and then began to do my homework. After writing, I asked my mother to change the roll paper. As a result, I made mistakes in all five reading and writing questions, and deducted 5 points. Teared mercilessly by my mother! I feel very sad! Dad copied another roll of paper for me after he came back from shopping. After dinner, I started the make-up exam again. As a result, there are still two errors in reading and writing. My mother didn't correct it for me, just tore it up.
Looking at the terrible tearing paper, my tears flowed down like raindrops! If I had been more careful the first time, the 5 points would not have been deducted and the roll paper would not have been torn; If I make up the exam for the first time, I will be more careful and won't repeat the tragedy! Why is this? My mind is not completely focused on the paper, and I don't do one thing wholeheartedly. I am always half-hearted, and I look around whenever there is trouble!
If my mother gives me another chance, I will do it seriously, intently and attentively! Mom, give me another chance. I will treat other homework with the best attitude. Let me prove it with my actions. I will make up my mind to correct it!
The third chapter of Mathematics Weekly saw a topic "Mathematical Problems in Life" in the mathematics textbook today. The topic is: "China's population is about 654.38+0.3 billion. If we save 654.38+0 cents per person per day, if so, our country will save about 6.5438+0.3 million yuan. If primary school students need to save about 65438+ tens of thousands of dollars from grade one to college, then this money can be provided to 1805 children who are out of school and have no money to go to school. Wouldn't it be nice to give these money to those people? "
After reading the above information, I thought: many hands make light work. Suddenly I remembered, many hands make light work? Not good, because I thought about it: if this population of about 65.438+300 million wastes 65.438+0 drops of water, then a * * wastes about 65.438+300 million drops of water, then what do you think is 65.438+300 million drops of water?
I did a small experiment: I put 1000 drops of water under the tap and weighed them with a scale. The weight of 1000 drops is 200 grams. I wrote another calculation.
Mathematics Weekly Article 4 20xx Year X Month X Day Week X Sunny
Today, I made an appointment with my classmates to have a picnic outside. I went to the supermarket and bought a bottle of 5 yuan. A loaf of bread 2 yuan, buy three; A pack of beef jerky 3 yuan 6 jiao; A hillbilly chicken leg, 2 yuan.
Aunt smiled and said to me, *** 15 yuan, I gave it to my aunt 15 yuan. When I walked out of the supermarket, I calculated: No, 5+2×3+3.6+2= 16.6 yuan, my aunt took 1.6 yuan, and I gave it back to her. Aunt said, "You are an honest boy"!
Mathematics can also make me understand the truth of being a man. I'm so happy.
On Saturday morning, my mother and sister went to Liangshan Park to play, and a big tree caught my eye. Mother asked, "Huanhuan, can you reach the height of this tree?" "Ok, use a bamboo pole as high as it, and then measure the length of that bamboo pole." Mother retorted, "Where did you get such a long bamboo pole?" "I ... I ..." I scratched my head. Suddenly I caught a glimpse of the shadow of the tree on the ground, and an idea flashed through my mind: by the way, didn't the teacher just teach the knowledge of proportion? I said excitedly, "Sister! Lend it to you! " My sister is puzzled: "How do you ask?" "In the same place, at the same time, the length of the shadow is proportional to the length of the object. Measure your height first, then the length of your shadow, calculate the ratio of your height to your shadow, then measure the shadow length of this big tree and calculate the height of this big tree. " I am serious.
Because I usually like small production, I always take a tape measure with me. The first time I measured my sister's height was 1. 56 meters, and then measure the length of her shadow is 0. 52 meters, their ratio is: 1.56: 0.52 = 3: 1, the shadow length of this big tree is 1. 1 m, and then the height is calculated:1.13 =. My mother and sister looked at me with thumbs up. I thought happily: Mathematics is really useful!
Math homework for weighing shoes
There is a problem in today's math homework to weigh a pair of shoes. So I went to my mother and asked for a scale. Mom said she didn't have weighing scale. What shall we do? However, as the saying goes, "Nothing is difficult in the world". I think there must be a way. So, I used my clever brain and came up with a homemade balance.
I cut off the paper covers of the empty moon cake box piece by piece, brought transparent folding tape, folded one of the paper covers into a regular triangle and put it on the table. Another piece of paper is made into the left and right disks of the balance and placed on the triangle in a balanced way. Then find something with weight at home as a weight. For example, my mother bought toothpaste, lipstick and other items, including 120g, 40g, 18g, 3g. I'm very excited to say that the shoe activity has started. I put the shoes on the left side of the homemade balance and the "weight of goods" on the right side. It is best to balance the weight on both sides. Then the sum of the weights is the weight of my shoes. Exactly 86 grams. Hard work pays off! I finally finished my math homework. Mom praised me when she found out.
He also joked with me: "In ancient times, there was a clever Cao Chong as an elephant, but now there is a clever Han Han as a shoe!" Say that finish, everyone laughed. It turns out that there are scales everywhere in life!
Reflection is a habit and consciousness, and continuous reflection will make continuous progress. Learning is a systematic project, and the measures to cultivate the habit of reflection are all-round, multi-angle and multi-level reflection. Students demonstrate and reflect on the problems that they didn't communicate with the teacher in the process of solving problems in class. The discussion of different solutions to some exercises in homework, the feelings of learning and experience can be vented and recorded in the form of math weekly diary (or math diary), so that teachers and students can have a fixed bridge of mutual understanding and communication. Therefore, writing a weekly diary of mathematics is conducive to cultivating students' reflective habits.
1. Math Weekly Journals have the function of establishing study files for themselves, which is a way to develop good reflection habits.
1, mathematics weekly diary is an important means to cultivate students' mathematical reflection consciousness and habit.
Mathematics weekly diary can record good exercise solutions or learning methods, and it is easy to solve wrong exercises and lessons of learning failure. To promote students to comprehensively monitor the whole process of mathematics learning and the gains and losses of mathematics learning experience, form the habit of being good at reviewing, summarizing and self-reflection, form the consciousness of self-reflection and improve the ability of mathematics reflection.
2. Mathematics weekly diary provides a way for students and teachers to cultivate reflective habits and form reflective consciousness.
Cultivating students' mathematical reflective ability requires not only teachers' demonstration, but also students' necessary reflective knowledge, and more importantly, students' personal experience and full participation. Therefore, in a sense, the math weekly diary can be said to be a reflection memorandum for class and problem solving.
Classroom reflection is a way to reflect on problems from the teacher's explanation, and learn to capture the problems that cause reflection or put forward reflective opinions.
Post-question reflection is to test or question the correctness of the conclusion after answering the question; Whether there are other or better solutions; Whether the title or conclusion of the question can be revised; Whether to extend the current proposition to the general situation; Further consider the completeness (sufficiency) of the problem and the accuracy of the conclusion.
3. Writing a weekly math report is not only a way of reflection, but also a measure to form reflection consciousness and cultivate reflection habits. It is an all-round, multi-angle and multi-level reflection. It is a comprehensive reflection to focus on summing up and reviewing.
The content of the weekly diary can include not only the reflection on learning mathematics knowledge and thinking methods, but also learning emotions, experience feelings and so on, so as to achieve the purpose of communication. In addition, writing a weekly diary of mathematics is less limited by time and space and less influenced by others, which provides students with a broader platform and publicizes their personality.
Second, writing a weekly diary of mathematics is self-cognition and self-monitoring in the process of self-cognition of mathematics. Reflection on Mathematics Teaching Week in Senior High School
The main purpose of writing a weekly math diary is:
First, I hope I can give you some enlightenment and deeply understand your own emotional changes and math learning experience. Through it,
You will have a better understanding of your math study. How do you study math? What kind of teaching method is best for you? What is the biggest difficulty in your math study? What makes you interested in math learning? What makes you feel depressed about your math study?
Second, the shared learning experience and the contents of the mathematics weekly diary will help teachers to understand the teaching effect and improve teaching, and find a teaching method that is satisfactory to both teachers and students faster.
Of course, it's important to insist on and encourage the writing of math weekly diary, and not to grade the weekly diary, but only to grade whether the task is completed or not.
Third, the writing guidance of mathematics weekly diary
Math weekly diary can be arranged or written once a week, about 15~20 minutes at the same time every week, or it can be summarized every weekend.
The content of the weekly diary can be constructed according to the following main problems:
(1) What math knowledge did you learn this week? Which ones are easy to learn and which ones are a little difficult? Reflection on Mathematics Teaching Week in Senior High School
(2) Do you have the most satisfactory solution to an exercise this week? What is your pride?
(3) What problems and nails did you encounter in your math study this week? Is it solved now? If so, how is it solved?
(4) Did you do wrong math exercises this week? What's wrong? Why not do this? What is the correct method?
(5) What is the biggest difficulty you encountered in your math study this week? How to solve it? What are the lessons?
(6) What mathematical ideas and methods do you think will be involved this week? What are the representative topics? What did you get?
(7) Which math class are you most satisfied with this week? What is the most lost paragraph? What is the reason?
(8) What are your learning experiences and feelings this week? Is there any confusion?

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.

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.
Weekly exercise notes (6)
During most of my internship, I learned banking business from the chief teller, and also learned lobby marketing skills from the lobby manager to maintain the queue order in the lobby and answer customer inquiries. Pay special attention to etiquette when working in the lobby. Etiquette is a code of conduct and norm formed by people in communication activities. The lobby manager who deals with customers all day represents the image and reputation of the enterprise, so be cautious in everything. The manager told me that to do a good job in lobby etiquette, we must do the following four things: capable, steady, confident and friendly. Business etiquette has four main contents:
(1) Answer customer questions.
(2) Diversion of customers in business.
(3) maintain order in the lobby.
(4) Marketing suitable wealth management products.
Among them, answering customers' questions requires the lobby manager to know every business of the bank and its operation process, so to be a good lobby manager, he must have rich knowledge. Because BOC has foreign exchange function, my main task as a lobby manager in BOC is to guide foreign customers to save and exchange foreign currency.
Harvest and experience of internship: Through this internship before graduation, I have a certain understanding of the basic business of xx Bank, and I can perform basic operations, and feel that I have gained a lot in other aspects. Because I have been living in a simple university campus, this graduation internship has undoubtedly become a platform for me to step into society and laid the foundation for my future step into society.
In life and study, I can't live without understanding and carefulness. However, in fact, I am very careless. Sometimes, I just can't speak.
I remember a math exam. I misread it because of carelessness, and naturally I made a mistake. The night before the exam, my parents urged me to say, "You are just too careless and have no confidence. You must be careful this time. Check carefully after you finish, and don't be careless. Otherwise, look at the word' serious' written on your palm. " Hearing this, I nodded and thought: I will never forget the word palm. I will examine the questions carefully, answer the questions carefully and check them carefully.
The exam has begun. From the first question, I will read it carefully and write it carefully. What should be checked is on papyrus. I finished this problem before class was over. Then I checked it again. I feel good about myself. However, when the polyurethane was delivered, I was completely dumbfounded. How can there be a wrong question? What's the matter? When I looked carefully, it turned out that the figures on the calculation were written backwards.
Through this exam, I know more about the importance of the word "earnest". In the future study, we should not be "careless" any more, but be serious again.
