A busy and full day has passed. I believe everyone has a lot of experience. Why don't you keep a diary now? Is it impossible to write without a clue? The following is about 200 words of math diary in the first grade winter vacation, which I sorted out for reference only. Welcome to reading.
Today I learned puzzles. I spelled ducklings, rabbits, small fish, trees and so on.
I use a small triangle as the duck's head and a parallelogram as the duck's nose. Use a big triangle as the duckling's body, a square as the duckling's leg, a big triangle as its tail and two small triangles as its feet. I can spell many different shapes.
This afternoon, the teacher announced that we would go for a spring outing tomorrow. Let's prepare some snacks. To prepare two bottles of drinks about 5 yuan and a bag of potato chips about 10 yuan. If you buy another bag of seaweed, it's 6 yuan. I think left and right. 5+ 10+6=2 1 yuan. The total * * * is 2 1 yuan.
I asked Mr. Chen and found that there was only 102 yuan left. "I wanted to think about the spring outing fee 60 yuan. Only 40 yuan is left. I think the rest should be saved for stationery.
Because my parents work very hard, I can't waste it, so I only bought a bottle of drinks and a bag of potato chips 2.5+ 10= 12.5 yuan. It only took 12.5 yuan. I am glad that I can use math to solve problems in my life.
Today, my mother gave me 50 yuan money to buy fruits and vegetables. I bought a bag of apples, 6 yuan money, a catty of cucumbers, a catty of 2 yuan, a catty of shrimps and a bag of strawberries, 5 yuan. The salesman asked me how much it was.
I listed in my mind: 50-6-2-28-5 = 4 1 (yuan), and quickly said that I want 4 1 yuan. The salesman then asked, "How much do I give you?" I said I would get my 9 yuan money back. The salesman praised me as great, and I was very happy. When I got home, I gave the rest of the money to my mother, and her mother smiled with satisfaction.
Math diary's first-year winter vacation is about 200 words. Chapter 4 is about to leave school. The teacher assigned a special math homework-making learning tools, saying that it is ok to do it according to the requirements of the second question on page 36 of the textbook.
I started doing it as soon as I got home. I took out my scissors and cut the cardboard into two disks, one large and one small.
Then determine the center of the circle, divide the circle into nine equal parts, and then write the nine numbers 1~9 on two circular surfaces respectively. Finally, find a toothpick to pass through the center of the circle and fix the two circles together. After I finished, I read the instructions in the book: turn around and say the product of multiplication of two aligned numbers. Every time you turn a grid, you can work out nine numbers. I started playing at once, turned around and said I would count to nine. After another round, I can form nine different multiplication formulas. This learning tool is really a good helper for me to recite formulas!
Today, we learned about RMB. 1 yuan has 10 1 angle, and 1 yuan has two 50 angles. 10 yuan contains 10 0 yuan, 10 yuan contains 2 5 yuan, 10 yuan contains 5 2 yuan, 100 yuan contains 2 50 yuan, 10 yuan contains 10.
Renminbi is divided into two denominations: paper money and coins. We should cherish RMB, don't scribble on it, scrimp and save at ordinary times, study hard and make progress every day.
On Saturday morning, several students came to my house to play. My mother suggested, "Do you want to have a skipping competition today?"
We happily agreed to mom's proposal and the game began. Xiaohong jumped 30 times, Xiao Fang jumped 25 times and I jumped 27 times. My mother asked us how many times we danced.
I remembered the continuous addition that the math teacher taught us to calculate. The same numbers should be aligned, starting with one digit. The column formula is 30+25+27=82 (pieces). Mother smiled happily after listening to our answer.
Today, I played darts with my sister. I found many math problems from this game!
A dart board has five circles, the innermost circle is a red heart, and shooting can get 10 points, the second circle 8 points, the third circle 5 points, the fourth circle 3 points, and the outermost circle 1 minute. My sister and I had a life-and-death contest.
Sister, she hit the fourth lap for the first time and got 3 points. The second shot dropped, and she didn't score! Just as I was smiling from ear to ear, my sister suddenly made progress. Hit the key and get 10 points. I am not happy now. Sister, she got 13!
It's my turn I aimed for a long time. I ran the third lap for the first time and got 5 points. The second shot was not very good, only 3 points. If I want to surpass my sister, I have to shoot the innermost heart for the second or third time. Finally, I took the second lap and won. I'm so happy!
Math diary's first-year winter vacation is about 200 words. In today's math class, we got to know RMB, including 100 yuan, 50 yuan, 20 yuan, 10 yuan, 5 yuan, 2 yuan, 1 yuan, 5 points, 2 points, 1 minute, 5 points, 2 points, 65438+. I know that among 100 yuan, there are 10 yuan, five 10 yuan in 50 yuan, and five 1 angles are five angles, 1 yuan = 1 angle,1angle.
We should not scribble on the RMB, but cherish it. Save money from an early age, don't misuse it, and form good habits.
Math diary's first-year winter vacation is about 200 words. Today, I got to know RMB, the face value of which is 100 yuan, 50 yuan, 20 yuan, 10 yuan, 5 yuan, 2 yuan, 1 yuan, 5 points, 2 points, 5 points, 2 points, 1 minute. There are five RMB 10 in 50 yuan, and five RMB 1 is 50, 1 = 10, 1 = 10. I also know that there are two kinds of RMB, one is paper money and the other is coins.
We should not scribble on the RMB, but cherish it. Save money from an early age, don't misuse it, and form good habits.
At the beginning of math diary 10 math class in the winter vacation of senior one, Mr. Zhou said that we were not proficient in formulas, and then gave us about 3 minutes to recite formulas at the same table.
I immediately carried my back to Zou Lele, my deskmate. I thought about the two formulas "5945" and "4936" for a long time, but I barely memorized them. There is also Zou Lele, who also has two sentences that are not very skilled.
After asking about everyone's recitation, Mr. Zhou selected a small representative from each group and held a group "password matching" contest. As a result, our fourth group won and everyone was very happy. Look! Some mouths bend like a crescent moon, but they can't help laughing, some jump up and some clap their hands! With teacher Zhou's "stop", the classroom suddenly became quiet.
Math diary, a freshman, has a winter vacation of about 200 words. 1 1 I like taking math classes and thinking about math problems. I am used to thinking about math problems that even my parents are often criticized. I signed up for a math interest group. This course is really interesting.
In the first class, the teacher of the interest group taught us to know graphics. What do you mean, dot? What is a line segment? What is a ray? What is a straight line?
I replied that a point occupies a position on the paper called a point, and two endpoints are connected to form a line segment. A ray has one endpoint, and the other side extends far, far away without end. A straight line has no end points and can extend to both sides indefinitely.
The teacher also taught us a lot of interesting knowledge. I study hard, and every time the teacher praises me for learning fast and well. In this way, I like learning math more.

Math diary is about 200 words in the first grade winter vacation 14. Because I didn't bring water, I went to learn to dance tonight; So, we are going to the supermarket to buy a bottle of mineral water. Mom usually buys it, so I don't even know how much a bottle of water costs.
Mom gave me one yuan, but! Aunt salesgirl said it wasn't enough. A bottle of mineral water costs 4 yuan money. Wow! It is four times more expensive than I expected.
I ran out to ask my mother for money again. My mother gave me ten yuan this time, and I gave it to my assistant aunt.
I calculated it myself, 10 yuan -4 yuan =6 yuan, and the aunt of the salesgirl should call me 6 yuan; My calculation is very accurate. My aunt, the shop assistant, gave me 6 yuan money.
I gave the rest of the money to my mother, and she praised me for being great!
A year's winter vacation in math diary takes about 200 words 15. Time will pass by second by second. Even if you read a word, it will take time, because time waits for no one.
On this day, I want to buy clothes, because clothes are on sale and my mother can't stop for a minute. Suddenly, my mother said, "Let me ask you a question. We have to leave at 2: 00 pm and arrive at the mall at 2: 40 pm. How long did it take? "
I think: 2: 00 pm can be regarded as 14: 00, then 2: 40 is 14: 40,14/4. So, I immediately replied "It took 40 minutes". Mom said, "Yes, it seems that math has improved a lot!" " ""mom, it's too late if you don't go! " "ah! I almost forgot. "
My reply: It doesn't matter if you don't switch to 24-hour timing. Just use 2: 40 -2: 00 =40. What did you say?/Sorry?
During the winter vacation of grade one in math diary 16, Xiaowen, a "little doctor" in our class, said to the students, "Today, I will give you an interesting math problem. The topic is: two mothers and two daughters are walking by the river. How many people are there at least? " Xiaojun said: "This is not simple! Of course, there are two mothers and two daughters, so there should be 2+2=4 (people). "
Xiaowen shook his head and said, "No, who has a different answer?" It suddenly occurred to me that my father had told me a similar topic and asked two fathers's two grandfathers. I said, "Let's look at the relationship between Xiao Lin and her mother. Xiao Lin is her mother's daughter, so there are 1 daughter and 1 mother here. Mom is grandma's daughter, so there are 1 daughter and 1 mother here.
On the other hand, two mothers and two daughters are together, and there are at least three people. "Everyone said," you really think. "
Math diary Winter Holiday of Grade One in Senior High School: 200 words or so 17 This afternoon, my brother and I had a family skipping competition under the leadership of my mother.
My first appearance was me. I just made a mistake after eight easy jumps. My mother told me to keep my mood stable and keep dancing. When I jumped to the 22nd floor, I was out of breath. Alas! I can't help it I shook the rope feebly. One minute finally arrived, "35 times". Brother smiled and counted off.
It's my brother's turn to jump. He jumped with his feet. The first few moves were very fast, but at the age of 28, my brother began to gasp. Finally, he finished the race with 40 points.
The third contestant is of course my mother. She jumped with one foot and two feet, and her performance was ok, 68. The skipping competition was over, and my mother asked me to add up the skipping scores of the three of us. 35+40+68= 143 (below) is really "I don't know, it's shocking". Today, the skipping performance of the three of us is not as good as that of Shi Yuwen in our class. It seems that it will take three summers to practice hard.
Today, my mother said to me, "Xue Fei, play a game with you!" " "I said," good! "
My mother brought a round cardboard and fixed a pointer in the center of the cardboard with a nail. The cardboard is divided into 24 squares on average, and the squares say 1-24, "My mother, what are the rules of the game?" "The rules of the game are simple: when the pointer points to an odd or even cell, the next number must be added. Adding up to a singular number means I win, and adding up to a double number means you win. "
I played more than a dozen times in a row and lost every time. "Why is it always singular?" I asked my mother. My mother said, "Think for yourself!" So, I racked my brains and finally reminded me: odd+even = odd. Now I understand that if the pointer turns to the singular case, then adding the next number is an even number; If the pointer points to an even grid, the next number added is singular. Therefore, when the pointer points to any grid, the total number is singular.
Today, when I was doing homework for a math interest group, I was stumped by a math problem: "A bunch of watermelons, half and half, half is less than half." How many watermelons are there in this pile? " This topic is to count the number of watermelons, but it has no figures, so many "half" can confuse me.
I was so anxious that I shouted at my sister, "How to calculate this problem?" My sister stared at it for a while and said with a smile, "If you think about it carefully, you can draw a picture." So, I suppose there are eight watermelons, and I draw eight watermelons on the paper. Therefore, one half (1) is less than the other half (2) 1. I think this is wrong. Later, when my eyes lit up, I took off half a watermelon, that is, four watermelons and a picture. "Half of the four watermelons are half watermelons, isn't it half less than half of this watermelon (1)?" I jumped for joy! "Ha ha! I calculated that there are four watermelons in this pile! "
Math diary: About 200 words. Today, xu teacher taught us to make three-dimensional figures with plasticine and toothpicks. Xu teacher asked us to build a prism and a cube according to the three-dimensional figure on the big screen, and then create an interesting three-dimensional figure by xu teacher's method. The children used their rich imagination to come up with all kinds of three-dimensional graphics. Some built cuboids to be done in the next class, some built the same shape as houses, and some built a very complicated iron tower, especially Li Yuxin, who had a great effort to build a three-story house. It was not finished until class was over, and her work was praised by the whole class. This interesting math class makes students understand that they can also build complex graphics with the simplest materials and make them ever-changing.
Today's math class is really interesting, and the students are smiling! I hope there will be more and more such classes in the future, which will make our math learning more and more enjoyable!
