Another day has passed. What's your summary? Why not keep a diary now? Is it impossible to write without a clue? The following are the math diary format requirements that I have carefully arranged. Welcome to draw lessons from and refer to. I hope it helps you.

First, the standard format

First of all, we should have a new name to catch people's eyes. Secondly, the date, weather and day of the week should be on another line. At the end of the third grade, there are classes and tutors.

Second, the materials are unique.

Writing about math diary is like writing an article. The choice of materials is very important. The selection of materials should be innovative and unique in perspective, so as to write a good math diary.

1, express the relationship between some numbers in mathematics in the form of fairy tales, which is full of childlike interest and cultivates students' imagination. For example, the oolong incident in the mathematics kingdom, the show of curves, and going to work straight.

2. As the saying goes: "There are three rivers in the chest and one river in the mouth." Therefore, in daily life, we should always pay attention to it everywhere and form the good habit of seeing, listening, asking, thinking and remembering. Usually let children observe and record their lives from a mathematical point of view, and they will no longer feel that they can't write. Usually, in our daily life, we often encounter many expenses, such as paying water, electricity and gas. Only with your heart, children will find a lot of material.

3. Summarize and sort out the knowledge of each unit. For example, we have learned the unit "Four Arithmetic", and students can sort out the knowledge of this unit. Only addition, subtraction, multiplication and division should be calculated from left to right. There are addition, subtraction, multiplication and division in the formula without brackets. You should calculate multiplication and division before addition and subtraction. First, four arithmetic expressions with brackets are calculated.

Through this combing, the following four examples of operation are enough.

4. Write a unique opinion on a topic. For example, if you encounter some exercises in your usual practice, you can write down your own unique ideas and share them with you.

5. Sort out the proposition math diary according to your recent knowledge. For example, after talking about the location and direction of the company, you can describe the general location of your home and the typical buildings near your home, and you can also write some general locations when traveling.

6. Students find hot issues in life and write on the theme of describing current events.

Third, make a good comment.

Facing children, math diary seems to have entered the children's world, where there are children's lives, their infinite reverie, their learning methods and sometimes their joys and sorrows. As a teacher, we should seize the opportunity to communicate with children and review carefully. Try to comment on children and write comments (you can write about advantages or hopes). For math diary's good writing, we should communicate in class, let students evaluate him, let students know the advantages of others and find out their own shortcomings. You can also use some available channels to show and comment on children's math diary. This will stimulate students' interest in writing about math diary.

How to write math diary format?

How many birds are there in each?

I met another math problem today, and it took me a lot of effort to solve it. The topic is: there are 30 birds in two trees, and 4 birds fly away from the second tree first. At this time, tree A flew to tree B with three birds, and the birds on the two trees were just equal. How many birds are there in each tree?

As soon as I saw the topic, I knew it was a reduction problem, so I solved it by the method of reduction problem. But when I checked, I found something was wrong. I will do it again more seriously. I think there are as many as four missing, half of them are 13, and the restored B-tree is14; A tree is 16. The formula is: (30-4) ÷ 2 = 13 (only); 13-3+4 =14 (only); 30- 14 = 16 (only). The answers are: a tree 16 and b tree 14.

By solving this problem, I understand that no matter what I do, I should be careful, otherwise, even if I master the solution to the problem, the result will be wrong.

consider

Today is Saturday, 10, 15. 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 that the math teacher said that "kilogram" has another name called "kilogram". I didn't expect to meet you today, and I know that I have gained 2 kilograms!

I was so happy on the way back! I must exercise my body!

Incredible data

Today, I came across such incredible data in a book: "A piece of paper with a thickness of 0.0 1 cm is thicker than Mount Everest after being folded in half for 30 times?"

This data is a bit "absurd" no matter how you listen to it. After all, it is a thin piece of paper. Can folding in half really surpass Everest? But many unexpected things may happen, so only through calculation can we uncover the mystery of all this.

Immediately I multiplied 0.0 1 cm by 2,1* * 30 times to get10737418.24cm.. Then, I converted the height of Mount Everest from 8848. 13 m to 8848 13 cm. By comparison, it is obvious that the thickness of paper folded in half for 30 times is indeed better than the height of Mount Everest, which is more than 10 times of the latter.

In fact, amazing data like this are everywhere in ordinary life, as long as you have a pair of eyes that are good at discovering.

The process of learning mathematics

There are still many episodes in learning math for me-in recent weeks, we have been learning how to divide by a number. Because of lack of experience, I don't know much. There are always mistakes when doing problems. My mother always teaches me when I am free, but my mind is still blank. I always feel that what my mother said is just something I don't understand.

Mother can't help me, so she has to let me do exercises by myself. My mother told me first: the division formula is like going down the stairs. If the highest digit cannot be divided by the divisor, move the second digit down. If the last digit is not enough to divide, write 0 directly where you write. What my mother said made me understand the mystery. Although there are still mistakes in doing the problem, I can correct them soon.

Understand the reasons for the split, let me understand the truth of life, do everything step by step like taking the stairs, down-to-earth, or you may make mistakes again and again!

Math diary format

"math diary" is to let students evaluate and record their studies in the form of diaries. It can be used not only to evaluate students' understanding of knowledge, but also to evaluate students' way of thinking. They can not only sum up what they have learned in mathematics, but also write their feelings, attitudes, difficulties and interests like talking to themselves. At the same time, teachers can also get some information about students' learning mathematics according to their math diary, which is convenient for evaluating students in time and adjusting teaching strategies.

Math diary's content is rich and colorful. It can be said that math diary can write anything related to mathematical knowledge, skills, will, emotion, activities, experience and practice. Specifically, there are mainly the following aspects:

1, class diary

It is mainly the record of students' own classroom learning. Usually, students' mastery, listening, cooperation, thinking, innovation and application of knowledge and skills in class will be recorded. For example:

Today, we learned about "triangle", and learned what a triangle is, its characteristics, its classification and its wide application in practice. What I learned most in this lesson is the characteristics of triangles, and there is another thing I don't understand: why can an obtuse triangle have only one obtuse angle instead of all three angles? I asked several other students, and they didn't want to. I have to ask the teacher to tell me again tomorrow. Look, it's good to have a problem. It can make me think more and understand what I have learned thoroughly.

2, thinking diary

It is necessary to record the thinking process of students in class, homework and problem solving. For example:

The teacher told us a question: 58 million kilometers = () 1 100 million kilometers. One team did this: the forward speed between 10,000 km and 100 million km is 10000, so divide 58 million km by 10000 and move the decimal point four places to the left, which is 58 million km. I have another idea: first rewrite 1 10,000 kilometers into kilometers, which is 58 million kilometers, and then put the decimal point in the lower right corner of its billion digits, which is 58 million kilometers. How's it going? Is my method good?

3. Cooperation Diary

It mainly records students' mutual help, mutual promotion, mutual learning and cooperation with classmates in mathematics learning. For example:

I didn't listen carefully today, so I handed in my homework very slowly. If not, I'll ask my classmate in the same place, but he won't talk. I know this because I have been asking him questions and bothering him these days. I don't blame him. Alas! You must listen carefully in the future. So I asked Liu Xiaoping, and she told me very carefully. When I handed in my homework, the teacher praised me for doing well, and I was very happy. In fact, the teacher should praise that classmate. As for which classmate, I think everyone already knows.

4. Life diaries are mainly used to record interesting and personally experienced situations about mathematics that children encounter in their lives, so that students feel that there is mathematics everywhere in their lives. For example:

At noon today, my mother asked me to buy 1 50 yuan of white sugar and 2 Jin of soy sauce, and gave me a piece of 10 yuan. After I bought it, the salesman gave me 30 cents change from 6 yuan. On the way home, I calculated: 1 kg soy sauce 1 yuan.60, 2 kg is 3 yuan.20, plus 1 yuan.50 sugar, one * * spent 4 yuan.70, 10 yuan -4 yuan.70: 5 yuan Triangle, so he should call me 5 yuan Triangle more. I went back to the clerk, who took back the extra change and said, "You are so honest and a good student!" " "ah! I used mathematics, and the role of mathematics is so great!

5, emotional diary

It mainly records the development and changes of students' emotions and attitudes in mathematics learning. For example:

At noon today, I found Zhang Can copying Jin Tairan's math study guide. I thought for a while, should I report to the teacher? If it is reported, it is for her good; If you don't report it, you will hurt her. So I told the teacher and the teacher called her out. She didn't say a word when she came in, as if she were angry with me. What should we do about such a thing?

6. Exam diary

It mainly records students' test-taking situation before the math test, problem-solving situation in the test and experience summary after the test. For example:

Today we finished the exam, and the results came down. I estimated that I could get more than 90 points, but I only got 87 points. I was careless and made a mistake. For example, "add two zeros at the end of an integer, and the original number will be expanded by 100 times." This judgment question is wrong, because adding two zeros after 0 doesn't count. I overlooked this point. We must carefully analyze and consider the problem comprehensively in the future.

7. Discovery Diary

It mainly records the process of students' independent inquiry, active discovery and practical innovation in mathematics. For example:

I found a phenomenon when playing with a calculator: 21-12 = 9, 43-34 = 9, 65-56 = 9, 76-67 = 9, 87-78 = 9 ... 32l-123 = 656. 765—567= 198……432 1— 1234=3087,5432—2345=3087,6543—3456=3087,7654—4567=3087……5432 1 — 12345=4 1976, 65432-23456 = 41976, 76543-34567 = 41976 ... Through observation, it is found that several consecutive natural numbers form an integer, and the number formed by them in descending order is subtracted from the number formed by descending order. If the number of' numbers' in the group number is certain, do you think mathematics is wonderful? Through research, I know: as long as you are willing to explore, you will make many wonderful discoveries, and then you will find how interesting mathematics is!

8. Story Diary

It mainly records some math stories that students have happened or heard. For example:

At home today, I asked my father a question: What is 10+ 10? Dad said, "20", and I said, "Wrong!" Dad said, "How much is it?" I said, "You should use 18, 10, 10 as the base. Isn't that 18? " After that, we all laughed.

9. The teacher's diary mainly records students' attitudes, feelings and suggestions to the teacher. For example, the teacher praised me three times for this class schedule. On one occasion, Sun Pei could not move the decimal point. I stood up and said to him, "expansion moves to the right, and contraction moves to the left." This is easy to remember. "The teacher praised me for summing up well. The second time is to do a problem that is both enlarged and reduced. I have my good method: synthesize first, determine whether to enlarge or reduce in the end, and then move the decimal point. The teacher praised my novel and unique method. The third time is that I have been actively answering questions. The teacher praised me for my energetic study. I really like this course. Teacher, I want to say to you: "You should praise us more in the future, and everyone should praise us. In this way, I can guarantee that every class in our class is happy. "

10, growth diary

It mainly records students' progress in learning, existing problems and the process of correction. For example:

I'm always distracted in class today. I always think about this and that, and my grades are also declining. It seems that I have fallen into a trap (inattention) and can't climb up. I think I must try my best to climb this damn trap! I also hope that students who fall into this trap will climb up as soon as possible. I am so happy today, because I finally climbed into this hateful trap. Trap! What a terrible word this is! But if you work hard and try again, this trap will not be so terrible. Nothing is difficult to the man who will try.

1 1, flash diary

I mainly record my experiences, thoughts, experiences and every success and Excellence in mathematics learning. After accumulation, I have written more than 30 articles about math diary. My classmates in our group praised me for my good writing. I summed it up and got some experiences: writing about the process of mathematical events that happened today; Write your own ideas about learning mathematics; The purpose of writing mathematics ... as long as you grasp the previous content and write carefully, you can write a good diary. My class's monthly evaluation is: You have been rated as a small celebrity in math diary, congratulations! We believe that according to the way you keep a diary, the whole class can write one good diary after another.

How to write the format of math diary?

"math diary" means that students record their feelings and experiences in the process of mathematics learning and application in the form of diaries. Math diary not only truly reflects the students' learning situation, but more importantly, relatively objectively reproduces the interaction between teaching and learning. By keeping a diary, students can sum up what they have learned in mathematics, write down their gains and puzzles, and inspire them to observe life with math diary.

Math diary should remember his own discoveries, thoughts, feelings and mathematical methods. What math diary recorded is not limited to one aspect. Its materials and contents are unrestrained, and you can listen, watch and practice in class, after class and in life. ...

1. Cognition of Writing Mathematics

Students can write down what they have learned, understood, mastered and unclear in class. Through writing, it helps students to review old knowledge, deepen their understanding and mastery of mathematical knowledge, especially mathematical concepts, and urge students to sort out knowledge points purposefully in order to realize the internalization of new knowledge.

For example, a classmate wrote a math diary after learning "rice and centimeters": "Today, we learned rice and centimeters. When I got home, I measured it with a rice ruler, only to know that my height is only 12 1 cm, my father's height is 179 cm, my father is 58 cm taller than me, and my feet are 19.

When teaching this content before, students were very vague about the length of centimeters. By recording math diary in practice, students not only have a further understanding of the length of centimeters, but also practice the math problem of "Yu"

2. Write math activities

When students write about math diary, they can record what they think and how they operate in class. In the process of learning, when the group discusses and communicates, how to say and think, what the classmates say and what the teacher says; In group cooperative learning, what do you do, what do your classmates do, and how do your teachers guide you. In this way, the process of writing math activities is a process of learning from classmates and summing up knowledge.

3. Write mathematical thinking

Writing mathematical thinking is the main content for students to write about math diary. They can write reflections, such as learning attitude, learning methods, learning habits, learning interests, answering methods, suggestions to teachers and so on. In this way, there is another green channel for communication between teachers and students, so as to build a bridge for emotional communication between teachers and students, and to know students' learning situation, grasp and understand knowledge and suggestions on teaching methods in time.

For example, a classmate wrote in math diary: "Do you know, teacher, I have been distracted in class recently, and my energy is not concentrated ..." A classmate wrote: "Miss Wang, you speak too slowly, and sometimes you complain too much." Some students wrote in their diaries: "We really want to play more math games in class, and it would be better if we could play them in middle schools and schools."

Visible, math diary is like a mirror, reminding teachers to constantly understand students and improve teaching methods.

4. Write math applications

Often instructing students to write and apply math diary will greatly broaden their knowledge horizons, expand their mathematical ability and improve their ability to solve practical problems in daily life.

Look at what this classmate wrote: "My mother took me to the supermarket to buy things after school this afternoon. We bought four bags of chocolates at 1 yuan 85 cents each and four loaves of bread at 1 yuan 1.5 cents each; I also bought a bag of flour, 23 yuan 6jiao. Here's my calculation. 1 bag of chocolate and 1 loaf of bread add up to 3 yuan. Multiply the quantity by 4 *** 12 yuan, and add a bag of flour ***35 yuan 60 points, which is consistent with the invoice. "

From this diary, we find that students are catching mathematical problems from their lives, exploring mathematical laws and actively using mathematical knowledge to solve practical problems in their lives. By writing math diary, students not only understand the application of mathematics in life, but also learn to observe and experience life from the perspective of mathematics.

In a word, writing about math diary is an important way of learning. Math diary not only recorded the children's flash of inspiration, but also left a mark of mathematics in their hearts, which enabled students to contact life more widely and observe life more carefully, and effectively realized the mathematicization of life. It realizes the integration of disciplines and shortens the spiritual distance between teachers and students. Let the children get a pen and write math diary. "math diary" can give them a pair of mathematical eyes, experience mathematical life and enjoy the rich rewards brought by mathematical thinking.
