How to write math diary?

The day has passed quickly, and we have a new view of people and things. We should keep a good diary. So do you really know how to keep a diary? The following is how I collect math diary's writings for you, hoping to help you.

How did math diary write 1 math diary? In fact, it's the same as keeping a diary in An 'an, except that it records things related to mathematics and can record mathematical stories around him. Can write about the application of mathematics in life; You can write about the mathematical phenomena you see and the mathematical problems you think of; Can write math-related stories; You can introduce the math knowledge you read in the book, including interesting math, math stories, math jokes, mathematicians' introduction, and how to play math games. You can write an answer to a math problem by yourself; You can also write about your experience in learning mathematics and your learning methods.

"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.

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 Diary

It is mainly used to record interesting and personally experienced scenes about mathematics that children encounter in their lives, so that students can feel that there is mathematics everywhere in their lives.

For example, at noon today, my mother asked me to buy 1 50 cents 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, a * * * spent 4 yuan.70, 10 yuan -4 yuan.70: 5 yuan Triangle, so he should look for me 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, after we finished the exam, our grades came down. I estimated that we 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, when playing with a calculator, I found a phenomenon: 21-kloc-0/2 = 9, 43-34 = 9, 65-56 = 9, 76-67 = 9, 87-78 = 9 ... 32l-123 = 66. 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 remains the same, will the number of numbers be 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. Teacher's Diary

It mainly records students' attitudes, feelings and suggestions to teachers.

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. "
