Interesting math diary for first grade?
Children are very naive and have many jokes in their lives. So what interesting things have happened to you? Let me take a look below, for reference only. oh.
Chapter 1
Sunny day on middle. People wear new clothes, eat New Year's dinner, set off fireworks, and watch parties. What we children are most looking forward to is collecting the New Year's money! This year, I am "full of energy" and the red envelopes are "full of money." How much money is there? I have to do the math.
On the night of New Year’s Eve, Yanqiao’s grandparents***, who are also my grandparents***, took out two red envelopes from the cabinet and handed them to me. I visited my uncle's house with my sister and said with a smile: "I wish you progress in your studies!" "Thank you, grandparents!" We both said in unison. Then, my aunt took out two red envelopes from my uncle's pocket and stuffed them into our pockets. My mother also took out the red envelopes and gave them to us.
In the evening, I couldn’t wait to open the bulging red envelopes. Wow! I was pleasantly surprised to find that there was 1,000 yuan in the red envelope given by my grandpa, 600 yuan from my uncle, and 1,000 yuan from my mother! Haha, I am rich! Do the math: 100100600=2600, I Now we have 2,600 yuan!
On the third day of the Lunar New Year, we went to Liyuan to pay New Year greetings to my grandparents. Grandma hugged me, then took out two red envelopes from her pocket and gave them to me, saying: "I want Happy learning!" I opened it and saw two for 220 yuan. "Eh? Why do you still have change?" "The change is for you, and the rest is for adults to keep." Grandma said with a smile. "Oh, that's it!"
Chapter 2
Sunny day on X, month, X, 201X
On Sunday afternoon, I was watching TV at home, and grandpa said : "I want to watch the weather forecast." I turned the channel to the weather forecast for my grandpa. I reluctantly walked to the kitchen and asked my grandma to make egg pancakes, but grandma said that today's meals are already prepared, so don't bother me anymore. , I had no choice but to go to my mother’s room to play darts, and the darts flew into a box. I was dumbfounded when I saw it. I broke a few eggs. Grandma saw it and said, "If you answer a few of them correctly, I won’t hit you for math questions.” The question is like this. Grandma bought 35 eggs this morning. You broke 6 of them. How many are left? I calculated silently: 10-6=4*** eggs, 25+4=29* ******, I quickly said the number was 29, you answered correctly, I won’t hit you this time, please don’t damage things next time, okay? I said remember it, thank you grandma for your tolerance.
Chapter 3
Sunny day, X month, X day, 201X
Today, I am sick. I have a headache, a fever, and can't even walk. After I told my father, he took me to the village clinic to see a doctor. As soon as I got there, an old doctor in his 60s took my temperature and said, "Fortunately, you guys arrived in time, otherwise the consequences would be disastrous. Get some salt water!"
Dad asked me to sit on the recliner while sitting on the couch. He sat down and asked the doctor: "How much is it?" "129 yuan." Dad took out two 100 yuan bills and gave them to the doctor. The doctor gave dad a 50 yuan bill, two 10 yuan coins and a one-yuan coin. , Dad immediately put the change into his wallet. I was sitting on the recliner. Seeing that the doctor hadn't come to give me an injection, I quietly helped my father calculate whether the amount of money he had recovered was correct. Dad paid 10100=200*** yuan*** and should be able to get back 200-129=71*** yuan***. The doctor’s money was: 5111=71*** yuan* **. Oh, yes, absolutely! On the way home, I talked about it with my father, and my father said happily: "You are such a ghost, you still don't forget to count money when you are sick!"
Chapter 4
Sunny day, X month, X, 201 The master fertilizes 50 apple trees and 20 pear trees every day. After a few days, all the pear trees are fertilized, but there are still 80 apple trees that have not been fertilized. I would like to ask: How many apple trees and pear trees are there in the orchard?
I am not intimidated by this question. The difficult problem can stimulate my interest. I think that apple trees are three times as large as pear trees. If both trees are to be fertilized on the same day, Master Wang should fertilize "20×3" apple trees and 20 pear trees every day. In fact, he only fertilized 50 apple trees every day, a difference of 10 trees, and finally a difference of 80 apple trees. From this, we can know that Master Lao Wang has been fertilizing for 8 days. There are 20 pear trees in one day, which means 160 pear trees in 8 days. Based on the first condition, we can know that there are 480 apple trees. This is to use the idea of hypothesis to solve problems, so I think the hypothesis method is actually a good way to solve problems.
Chapter 5
Sunny day, X month, X, 201 expenses incurred. The first is tuition.
Tuition fee is 410 yuan, plus 20 yuan for drinking water, ***430 yuan. Then there is the fee of 180 yuan for the Olympic Mathematics School, and it is estimated that there is also a 20 yuan transportation fee, which is 200 yuan.
There is also money for exercise books: 2 copies of "Lectures and Lessons" for 21.5 yuan; 1 copy of "English Exercises" for 9.9 yuan; 2 copies of "Examination Papers" for 15.9 yuan; 3 copies of "Jiangsu Exam Papers" The book is 21 yuan. 21.5+9.9+15.9+13+21=81.3***yuan***. Study fee: 432081.3=711.3***yuan***. Living expenses: I will drink about 5 cartons of milk this semester, 5×30=150*** yuan***. Each meal costs about 2 to 3 yuan. Calculating it at 2.5 yuan, 2.5×3×30×5=1125*** yuan***. "What else is there?" I bit my pencil and said to myself, "And your school supplies."
Hey, mom is back. Yes, there are also school supplies. School supplies: a pencil case 8 yuan, a pencil case 3 yuan*** very cheap, clearance items***, six pencils 3 yuan, an eraser 0.5 yuan, two set squares 1 yuan, two mechanical pencils 5 yuan, 8+3+0.5+1+5=20.5***yuan***. Total expenditure: 711.3+151125+20.5=2006.8***yuan***. Wow, I didn’t expect that I, who usually don’t spend much money, would actually ask my parents to spend 2,006.8 yuan on me this semester.
It seems that I need to save money!
