For example, an interesting application problem, an interesting formula and an interesting solution ... This month, I saw the fun of mathematics with my own eyes. I remember one day this month, Mr. Wang, a math teacher, told us about exploration and discovery in class (1)-an interesting formula.
In this lesson, we broke through four levels in a row and all passed. The first level: wonderful pagoda. There are some interesting formulas:1*1=1*11=12/kloc-0. 1 1 1= 1232 1 1 1 1 1* 1 1 1 1=? 1 1 1 1 1* 1 1 1 1 1=? I just started thinking: the answers to the examples are all 1, and the answers should be: 123 432 1, 12345432 1.
The second level: strange 142857. The third level: the magical 9.
The fourth level: looking for mysterious numbers. I calculated according to the same idea, and in this way, I found mathematics very interesting.
There are many such examples, because mathematics is interesting, so I will keep looking for the fun of mathematics, because only by looking for the fun of mathematics can I stimulate my interest, and only by persistence can I succeed.
2. Count from 1 to 100. My favorite number is 66, 88, 99 and so on, but my favorite number is the boss's three digits-"100". Why?
100- 100. Every exam from grade one to grade six, what I yearn for most is 100. It stands for victory, for first place, and for your parents' reward. However, the ideal score of 100 is not so easy to achieve. You have to work hard to get it. Can you not say that 100 is the result of your hard work and sweat?
100- 100 yuan. It is the largest denomination banknote in RMB, commonly known as "hundred-dollar bill". It can buy many things. If you can take out a pile of money at once and let it flow and roll at your fingertips, it is a symbol of your wealth.
100- 100 days. Many foreign tourists came to China 100 days before the opening of the Beijing Olympic Games, and the Olympic Games that people all over the country are waiting for will open in 100 days. Isn't this exciting enough?
100-"Hundred Eggs". Every final exam, I will ask my mother to prepare two eggs for me, and with a fried dough stick, it will become a "hundred eggs". Morality, naturally, I want to get 100. However, this method is purely self-consolation, and the real score of 100 is earned by heart+sweat+earnest.
100-my favorite number.
3. Composition on Numbers 1234567
1234567 are seven very common numbers. Looking at these figures alone, most people think of numbers. However, aside from those numbers, every number can make people think.
1 is extreme.
1 is predestined by heaven and praised or devalued by people, but it is always special. When 1 is positive, such as champion, champion, etc. It is praised by people, and many pairs of eyes stare at it with envy, while 1 fully enjoys "once you climb to the top, you will see that other mountains look short under the sky." . However, the higher you climb, the more you are afraid of falling, so 1 works harder than others. If 1 falls, it must fall harder than others. 1 when counting backwards, it's just ridicule. If there are two 1, then it loses its luster and value. "One mountain can't accommodate two tigers".
What a pity
For 2, Heaven is extremely unfair, just one step away, which is far from the treatment of 1. 2 can only live with regrets forever, but when 1 falls, 2 has a chance to go up. In fact, I should feel lucky. After all, I am "below one person and above ten thousand people", and many people are squeezing this seat. However, people grow through hard work. How can they see the rainbow without experiencing wind and rain? Work hard! 2!
3 is luck.
You are really a lucky dog. Only gold, silver and copper are in the top three in the Olympic Games, and the fourth place doesn't even have a brand; In the ancient imperial examination, only the champion, the champion and the flower explorer had proper names, and the fourth place was only anonymous; Some competitions only have the first prize, the second prize and the third prize. The next prize may be a commemorative prize or an encouragement prize, so you also have a certain weight. Don't be too sad!
4 is to make persistent efforts, 5 is to make persistent efforts.
The combination of 4 and 5 is persistent and the least concerned. When people leave praise to the top three, 4 and 5 are enjoying the taste. When 4 and 5 stand up again, you should be careful of the top three. They are often dark horses. If you don't advance, you will retreat, just as the old saying goes: "If you don't advance, you will retreat."
Six and seven are hopeless.
6 and 7 are equivalent to the reciprocal of 1 and the reciprocal of 2. I write about them like this because it can comfort them. There is a story: a man asked another man, "Where did you run in the running race?" "Seventh." "So, how many people took part in the competition?" "Seven." As if it would make people look better on their faces. The reason why they are written together is that almost no one will think there is any difference between the penultimate 1 and the penultimate 2, unless the penultimate 2 is itself.
1234567, in fact, they are all the same, but people have given them different meanings, which makes them intriguing.
4. math diary 100 This morning, I started the "launching ceremony" of reviewing, practicing and strengthening mathematics according to the "holiday plan" my father asked me to write!
I thought it was a little difficult at first, but it became easier and easier, and I thought math was so interesting! For example:
There is a five-digit number, the lowest digit is 8, the highest digit is 3, one digit is twice the tenth digit, and the sum of the first three digits and the last three digits is 19. What is this five-digit number?
Answer:
First calculate the highest and lowest digits of this five-digit number, then calculate the ten-digit number 8÷2=4, then calculate 8+4 =1219-12 = 7, and finally calculate 3+7 =1019.
I didn't like math before. It was boring. Now I think math is so simple and interesting! You will love math!
5. I am actually very happy to learn 800 words in the composition "",actually very happy. San Mao said, "The deepest and most peaceful happiness in life is to look at heaven and earth, look at life and slowly taste its harmony and beauty." Calm down and open the book, those deposited ink will fill the space bit by bit, and those dusty happiness will open bit by bit. Learning is actually very happy ... I used to think I studied and did too much homework. The happiness in life was thrown into the wastebasket with a piece of draft paper. In hesitation, I remembered a sentence by Zhang Ailing: "Give me a reason, I can trust the world again, and I can embrace this desolate city without hesitation." I am seriously looking for a reason to make my life happy. So I stopped worrying and complaining. I quietly opened the book, every page was carefully written, and every question was analyzed. Every trace is neat and delicate. When I was resting, I was surprised to find that my sleeves were wet. A drop of sweat on my forehead no longer makes me feel inexplicably hot, but that breeze has immersed me in a world that seems empty. Because the feeling of calmness and fullness is the joy of life. I was reminded of Bi Shumin's words, "Life is meaningless. But you must give her a meaning. " She faced the vast snow on Kunlun Mountain and got the true meaning of life. The ethereal world will make people think for a long time. But in my ordinary and busy life every day, I found a happy place in life: I have no distractions, and I have completed my task in a down-to-earth manner. When I am full and calm, this quiet and empty state of mind will make people feel harmonious. Life is picturesque. The white moon seems to be a gorgeous flower blooming in the dark. In the bright moonlight, the flowers in my life bloom one after another. It slowly turned into a yellow halo, which accompanied me to study at my desk under the lamp. I looked up and soaked my dry eyes with water a little, but even if I was tired, I no longer felt lonely. Because what I face is no longer a lonely lamp, but my inner satisfaction and love for learning. Light up your dreams a little bit. Those books and papers have become a solid road, wider and flatter. Every sentence in the book seems like a blooming flower, no longer a fantasy world, but a flower that blooms on the road of life and never fades! Life is like a flower, it is as beautiful as a flower's smile. The fragrance of life permeates my heart and my world. I seem to see that my long-cherished dream is blooming in the depths of the flowers. I know I'm taking a beautiful road, but no matter which way, I'll go down steadily ... learning makes me happier! Chinese-my favorite Many girls prefer liberal arts to science. I am no exception. From grade one to grade five, I have a soft spot for Chinese. Chinese is the mother of encyclopedias, worthy of the name. Even mathematics that has nothing to do with it is actually closely related to Chinese. Look! When I meet an application problem, I can only calculate numbers but can't read words. Can you understand the meaning of the application problem? I don't know the meaning of the title when I meet it. Can you do it? I can't do it. So Chinese is the mother of encyclopedias. Chinese is an interesting subject. Someone asked, "Isn't Chinese boring?" Looking at this series of new words, I feel bored. "No, absolutely not. The interest of Chinese is reflected in the new words. Look! Adding a sum to "constant" becomes "enjoyment", "person" becomes "big" and "big" becomes "heaven". How interesting! Therefore, Chinese is a very interesting subject. Chinese is also a happy world. Someone asked, "Looking at every word in a Chinese book is simply a boring world. What can be regarded as a happy world? "No, absolutely not. The fun of Chinese lies in word for word. You see: "Duckling is eating fish in the river" can be changed to "Duckling is eating fish in the river", such as "match-firewood, accident-story, bee-honey". These words that can be read backwards are not very interesting and won't make you feel happy? Chinese has many advantages. Perhaps the fun of Chinese is countless stars, which are the biggest, brightest and hottest among the stars-the sun. During the day, it illuminates us, but at night, it shines around the stars ... China people, you are very interesting, you make people happy! You are very deep. You are my favorite.
6. An Interesting Math Lesson Composition 400 Long ago, the teacher gave us an interesting math lesson, which was the most interesting lesson I have ever had.
The bell rang and we hurried back to the classroom. The teacher was already standing on the podium, writing something on the blackboard ... I had to take out my book absently. Mathematics has always been a subject I don't like. Very boring, very boring ... I mechanically took notes on my desk, waiting for class to end.
A, b, c, square, decimal, fraction, percentage ... This lesson is about the number axis. I thought it was a boring class, but I can clearly feel the cheerful mood of the helicopter students, which is not available in any class. I couldn't help laughing and raised my hand. ...
The teacher compared the numbers to a big family. There are many small families in this family.
Positive numbers, negative numbers ... and more small families, integers and fractions ... The teacher talked about the relationship between them seriously, like telling the history of a family, and occasionally a few humorous words caused a burst of laughter ... 45 minutes passed in joy, and the bell rang slowly, and everyone left the classroom wanting more.
That class. I like math, like those small numbers, abstruse formulas, simple equations ... It was that interesting math class that made me fall in love with math.
7. How to write the first of the 50 words of math diary in the fifth grade of primary school: buy chicken legs. Today, I made an appointment with my classmates to go out for a picnic. I went to the supermarket and bought a bottle from 5 yuan. A loaf of bread 2 yuan, buy three; A pack of beef jerky 3 yuan 6 jiao; A hillbilly chicken leg, 2 yuan.
Aunt smiled and said to me: A * * 15 yuan, I gave it to my aunt 15 yuan. Out of the supermarket, I calculated: No, 5+2*3+3.6+2= 16.6 yuan (yuan). My aunt took 1.6 yuan and I gave it back to her. Aunt said, "You are an honest boy"! Mathematics can also make me understand the truth of being a man. I'm so happy.
Math diary This morning, I started the "launching ceremony" of reviewing, practicing and strengthening mathematics according to the "holiday plan" my father asked me to write! I thought it was a little difficult at first, but it became easier and easier, and I thought math was so interesting!

The sum of the first three digits and the last three digits is 19. What is this five-digit number? Answer: First, calculate the highest and lowest digits of this five-digit number, then calculate the decimal number 8÷2=4, then calculate 8+4 =1219-12 = 7, and finally calculate 3+7 =10/kloc-0. I didn't like math before. It was boring. Now I think math is so simple and interesting! You are sure to like math.
8. 100 words math diary math diary 100 words 10 (looking for a stick)
After lunch, my mother took me to the hillside to find a stick. My mother and I cut the thatched straw home first, and then my mother measured the length of 10 cm with a rice ruler and cut it open with scissors. While cutting, my mother asked me to count. When I counted 10, I tied a bundle.
I tied a 10 bundle, and my mother said, ok, I won't cut it. Then, my mother asked me to unpack the 10 bundle and count it to 100. Add five more numbers to100; I counted correctly. My mother asked me: how else to count? 10 root, 10 root number.
"A bundle of 10, how many editions do you want to bundle 100?" I thought for a moment and said, "10 bundle." Ma Maquan said happily, "Yes, you are so smart!" I think counting is really interesting!
