I'm in the first grade. During the learning process of addition and subtraction within 10, my parents and I often play poker at home 10. I like it very much. I am happy to get two cards accurately every time. Sometimes I make mistakes when I'm in a hurry. It doesn't matter. If I lose, I win. Don't make a mistake next time.
Mom and dad said that this is not just a game, but also a study. It turns out that learning can be so simple and interesting.

Yesterday, when I did my math homework, I finished it quickly. My mother asked me to have a checkup. I was fun and finished the inspection. My mother saw that I was in a hurry, so she looked it up for me and found that I made a lot of mistakes.
Mom asked me to come and correct it. I'll check how many points I want to deduct as I change it. I'll deduct them ... The scores are getting less and less! I was ashamed, so I said, "We should study hard, listen to our teachers and mothers, do our homework and study hard, so as to make greater progress."

A shepherd goes to herd sheep every day. One day, he counted and found that two sheep were missing. He didn't care, and the next day he lost two. He panicked. At this rate, how did he get it? One day, two days, four days, three days, four days ... he dared not think about it and was determined to find out the reason.
On the third day, when he was herding sheep, he never left the flock.
Suddenly, he found something special about a sheep, so he took a closer look and was shocked! It was not a sheep, but a wolf in sheep's clothing. He was so angry that he hit the wolf hard with a wooden stick. Yelling, "Kill you wolf in sheep's clothing." The wolf was killed and the sheep was saved.

This morning, I came across a painting, which appeared in a book. I think this painting is very beautiful. When I enjoyed it, I found that there were many symmetrical pictures in it.
There are three landscape paintings, a four-legged table, a TV and three exercise books in this painting. I guess this must be the room of a child who loves to study.
I looked at it, and I knew: all three picture frames are symmetrical, so are the TV and exercise books!
I deeply realized that there is mathematics everywhere in life.

Then there were some small mistakes, and I thought, I'm still not serious enough. Mom said that since the beginning of school, my study has regressed, and I must redouble my efforts.
After listening to my mother's words, I think I must study hard, get rid of my careless bad habits and habits, and strive to get good grades.

Along the way, Qi Xin and Qi Xin worked together and answered all the math problems correctly. With their help, Hipatia successfully found her father. This story tells me that unity is strength!

Today, I went shopping with my parents. I saw signs selling houses everywhere in the alley, so a question came into my mind. I asked my parents: "Those agents introduced people to buy houses, and he couldn't make any money. Isn't it a waste of time? "
Dad said to me, "Of course, if you buy this house 1 10,000 yuan, the intermediary will earn 5,000 yuan." Now I see that people in the original organization can earn 0.5% money.

I saw a math story in an extracurricular book today. It is said that during the period of War of Resistance against Japanese Aggression, the great mathematician Hua taught in The National SouthWest Associated University and lived in poverty. When he spent all the money in the family, his wife gave birth to a boy, and he named the child Huaguang.
I thought the story was very interesting, so I quickly told my mother who was cooking. My mother is a math teacher, and I don't know the origin of the name "Huaguang". I make fun of her severely, hahaha!

I was bungee jumping with Yazhong and Mans this evening. We were dancing happily when Muncie said, "I have a math problem for you to solve. I have 65,438+08 sweets, 6 for Yazhong and 5 for Yanzi. How many sweets did you buy? "
We have calculated that we can add 618+518 =11. How much is left? I calculated again and put1-1118 = 718. It turns out that there are only 7 18 left!
How interesting the scores are! There is fragmentary knowledge in life.

In the second class this morning, Mr. Dong walked into the classroom with hurried steps and said it was time for an oral test. I quickly picked up the pencil box. After the teacher handed out the paper, I jotted down the class, name and student number, only to hear the teacher say, "Ready, let's go." The classroom is very quiet, and I can only hear the writing sound of "Sasha Vujacic". I was just about to hand over the paper to Mr. Dong when he said, "Don't hand it in, go back to your seat and check." I quickly stopped. After a while, Mr. Dong's timer started, and Si Zexin quickly put away our group's papers.
After getting up in the afternoon, the teacher asked several students to hand out papers. I looked at the newspaper. The result is 94 points, which means that the teacher's question is wrong, so I must be careful when checking in the future, and there will be good results!

In life, mathematics is everywhere. For example: buy food! Buy stationery! Measuring cloth, etc. , all need to use mathematics.
This semester, the teacher taught a new knowledge, that is, the multiplication and division of decimals. This knowledge can help me a lot!
Last night, my mother went to buy oranges together. A kilo of oranges is 1.8 yuan, and my mother bought 4.5 kilos, which should be 8. 1 yuan. But the clerk is careless and doesn't know how to calculate. It's 9 yuan money. Fortunately, I used the knowledge of Protestantism to do a calculation in my mind this semester and immediately corrected the salesman's mistake.
Not only did my aunt, the shop assistant, praise me for my cleverness and my ability to multiply and divide after decimal point in such a small city, but on my way home, my mother also praised me for saving 0.9 yuan for her, and the knowledge I learned can be applied flexibly in my life.
Yes! If you don't learn this math well, it's not only 0.9 yuan that will lose, but also hundreds, thousands or even hundreds of millions!
