The teacher read my name and I left my seat to get the test paper. I looked at it. Oh, my God! Only 86 points! My heart suddenly became cold, like being poured with cold water, which made me cold from head to toe. I went back to my seat.
I picked up the test paper and corrected it carefully. It turns out that I made two mistakes in filling in the blank and got two points deducted. The multiple-choice questions were also wrong by two questions, and four points were deducted; There is also a calculation problem that is wrong, and three points are deducted; The application problem is wrong in a five-point problem. Alas ..... I was so careless. If I had checked carefully during the exam, I wouldn't have done so badly. I really regret it, but unfortunately there is no regret medicine in this world.
I must carefully check my next exam.
Math diary 2 20xx July 27th Friday weather: sunny.
At noon today, the weather is very hot, and the sun is burning the earth like a big fireball. Cicada can't stand the sun, so she has to hide in the trunk and complain.
My sister and I came back from crazy play outside, so hot that we wanted to eat some fruit to quench our thirst. As it happens, my aunt took out five beautiful peaches from the room. My sister and I stared at the peaches on the plate, and everyone wanted another one. Aunt saw it and encouraged us to use math knowledge flexibly to have a competition-outsmart peaches. The rule is: whoever gets the last peach wins.
My sister started first. Without thinking, she picked up two peaches and chewed them with relish. My head was running at full speed, and suddenly a coup came to me. I didn't take two first, like my sister did, but I took a Momo, and my sister was secretly pleased. I eat peaches slowly because my sister has chewed a peach and I only ate half of it. She chewed a peach and a half, so I ate all the peaches in my hand, so I picked up the two peaches left on the plate like lightning, shook my fingers smartly in front of her and said, Little sister, if you want to beat me, read more books for a few years! Then he moved a chair and sat down, munching on peaches.
Hmm! This peach tastes really good!
Three children in math diary, when they arrive for the Spring Festival, will think: How much lucky money will I receive this year? How to use it after receiving it, this year may be tuition, this year may be pocket money, and so on. What about me? My mother keeps the lucky money in the bank every year. When I grow up, I will use it if necessary, such as paying expensive tuition. Go on a trip; Buying a house and a car can be sponsored a little, and so on. There are thousands every year, and now it is estimated that there are tens of thousands.
Hope, hope, hope, the day of giving lucky money this year has finally arrived!
"Tintin ..." The doorbell rang and I hurried to open it. At the door stood my little aunt, my sister-in-law's father, aunt, grandpa, grandma, grandpa, grandma … I stood behind them, hammering their backs and rubbing their waists, which was very clever. If I do, maybe they will give me more lucky money, haha!
Today, my mother cooked a sumptuous meal for the guests. What are my favorite dishes, such as salted duck, braised pork, scrambled eggs with tomatoes and so on? After dinner, my mother sent them away. I hurried back to my bedroom and excitedly counted this year's lucky money,100,200,300 ... 900! Huh? Only 1900? I had 20xx last year. Didn't someone send it to me? I'm confused.
At this moment, the doorbell rang again, and it was my uncle who came back! He gave me a red envelope, saying that I had eaten and drunk just now, and I remembered it when I went out, and then I turned around and left.
This year, I added 20xx yuan, which includes the expectations of my elders. As the saying goes, "One hundred dollars grows in the colored thread, and then I put it away from the pillow to discuss the price of firecrackers and flutes, which kept Joule busy all night." This is because the elders hope that we can spend the first year safely. They believe that when evil spirits or years hurt children, children can use the money to bribe them and turn evil into goodness. This is not superstition, but the love of our elders. Therefore, we should study hard, live up to their expectations and live happily every day!
Math diary 4 Everything in life is inseparable from mathematics. As long as you are good at observation, you will find that mathematics cannot be separated from you. After studying the knowledge of proportion for six years, I deeply realized that mathematics has brought us many benefits.
It's a sunny afternoon. My brother and I have an appointment to meet at 2 o'clock in the forest park, and then we will go to the zoo to play together. After arriving at our destination, we had to buy a map of the park, because this was our first visit to the zoo in Forest Park. After I got the map, my brother crept up to me and grabbed it. I have no choice but to restrain my unreasonable behavior towards this "little naughty boy" Then my brother solemnly said to me, "Brother, today my guide will take you to see the lion!" " "At this time, I thought to myself: I hope it won't be the opposite!
Then my brother took me everywhere like a headless fly. After about an hour, I finally couldn't help it. I shouted, "What are you doing? I'm exhausted. Why haven't I arrived yet? " I took the map back directly, and it suddenly dawned on me at first glance that it was my pushy brother who made up figures and interpreted the scale of the map as 1: 5000 as 1 cm representing the actual 5000 cm. "Well, learning a skill is really important! If you are as self-righteous as your younger brother and don't study hard, the consequences are often self-defeating! " Then, according to what I learned, soon, we came to the lion. Look at my brother's envy. He's begging me to accept him as an apprentice!
Knowledge is the key to success, students, study hard! Let's create a better tomorrow with our own efforts!
Math diary Chapter 5 Students, when we do our homework, we must read the topic clearly. Because of carelessness, I often make mistakes in the topic, not because I can't. For example, "① The sides of the three bricks are rectangular, with a length of 20 decimeters and a width of 10 decimeter. What's the circumference? (2) The rectangular perimeter of three bricks with a length of 20 decimeters and a width of 10 decimeter? Just a few words, the practice is different. The first problem is (20+ 10)×2=60 (decimeter). The second problem is (20×3+ 10)×2= 140 (decimeter). So we can't be careless when we do our homework.
Math diary, the sixth chapter begins. Teacher Wang rushed into the classroom and told us to choose some students to take part in the labor. I thought to myself: I can't miss this opportunity. So, I raised my hand over my head, and the teacher actually chose me, which made me overjoyed. Why? Because I am the youngest and shortest in my class, I have always been taken care of at work.
What do you do? Sweep the floor, clean the glass, or ... alas! If you can't guess, just listen to the teacher. Under the leadership of Mr. Wang, we came to the "guardian" on both sides of the school gate-under the willow tree. It turns out that Teacher Wang asked us to beautify several willows on both sides of the gate with ash trees.
We carefully observe the teacher's every move. I saw the teacher put some white ash in the basin, then poured half a basin of water and stirred it with a small stick. Then, the teacher showed us two trees, and we beautified the rest. "Hey, it's not easy!" After reading the teacher's demonstration, I thought to myself.
At first, we followed the teacher's example, using a broom as a brush and dipping it in white water, starting with the red paint mark on the trunk and brushing it down the trunk. But my brush is always disobedient. You let it go left, it turned right and kept swinging, and I was soon splashed with a lot of white spots. Only then did I know that the task was "arduous" (not simple)! At first, we were very energetic and sweaty, but after brushing for a while, we were too tired to move and were listless. I think teachers often teach us that persistence is victory. So, I encouraged my companions to stick to it, and everyone cheered up and painted ... I looked up at Li Ming, haha, and I couldn't help laughing. Li Ming became a "Chinese Pulsatilla". He also looked up at me and said that my face was yellow and white.
Math diary: An unforgettable labor, a fourth-grade pupil: After the labor, our faces, clothes and trousers were covered with small white spots, all of which became "clowns" in the play. Look at all the "guards", wearing the white skirts we gave her, gloating. "Oh, I'm exhausted today!" I can't help but say. They replied, "Yes, the clothes are too dirty, and my mother should criticize them again." At this time, Mr. Wang came, looked at the fruits of our labor and gave a thumbs-up happily: "You are really capable!" " "Not to mention how proud we are.
I can't forget this job, because we exchanged hard sweat for the health of willow trees and beautified the campus environment at the same time.
Math diary 7 Recently, our students from grade three to grade six had a math exam. I only got 92.5 points in this exam. Carelessness made me do a lot. You're right. It's not that I can't. It was careless. There are often some size problems. Without these problems, I would be better. There is a saying: "The first mistake may be excusable, but the second mistake shows that you are a' fool'." Maybe I am this "idiot". My grades are like an olive. Olives hang from the cliff. If you are not careful, you will "bump into …" and fall down.
Achievement depends not on thinking high, but on hard work. An ideal without action is a fantasy. As Nietzsche said, the value of a thing sometimes depends not on people's income, but on people's efforts-on how much you have paid for it. This sentence is correct. Wisdom does not lie in profound knowledge. We can't know everything. Wisdom lies not in knowing as much as possible, but in knowing what we need most and what we don't need to know.
Through this exam, I not only tested what I have learned recently, but also exposed many shortcomings of myself, so that I can correct them in time in my future study.
Math diary is not old, but his heart is failing. I'm bored today. Ha ha.
Fractional multiplication exercises. Repeat yesterday's "story". At the beginning of the class, review the calculation methods of fractional multiplication by integer and fractional multiplication by fraction, and then ask the students to summarize the calculation methods of fractional multiplication in one sentence, resulting in cognitive conflicts. However, students go through the psychological process of summarizing concepts. To my surprise, Lu j x can also be completely summarized. Whether she attended the summer school or not, it was a relief and comfort to me. (Although it is not difficult to summarize, it is still ~ for some students, hehe) After summing up, practice one by one according to the contents of the textbook. Without much new ideas, students can cope with it, and the correct rate is quite high.
It is worth thinking that after three years of teaching life, I am still not clear about the determination of the content of practical courses. Of course, the two options of "pressing books" or customizing content will not. However, the consideration of content design is not deep enough and needs to be studied.
Judging from the practice of fractional multiplication calculation these days, students don't have a deep understanding of the sentence "scores can be dropped first" Some students sometimes can't even work out a clear formula, which does not rule out their laziness, but we can't ignore the long-term results. Or some students calculate the scores first, which is of course good, but in the long run, it is always easier to calculate the scores first and then calculate them. This should be emphasized in future exercises, but students will form a habit.
