Sixth grade mathematics composition

Everyone has the experience of writing a composition in study, work or life, so you are familiar with it. Writing is a narrative method to express a theme through words. How to write a thoughtful and literary composition? The following are nine sixth-grade math compositions I collected for you. Welcome to reading. I hope you will like them.

Yesterday, it was really a coincidence that I received a short message from Mr. Fang, recommending children to teach math to their parents. At my home, I just finished a math class on "Numbers" taught by Yaoyao. The children are in high spirits, and finally they can give lessons to their parents who are usually "above". I am honored to be a teacher and have the opportunity to be a primary school student, listening to my son give me a math class.

"Stand up, hello, Mr. Fang." I stood up and bowed deeply to Mr. Fang played by Yaoyao, which my son personally demonstrated to me. "Hello, classmate, please sit down!" Yaoyao smiled and replied, "No, it's a smile. Now it's a class. Can teachers do this? Be serious, okay? Let's start over. " Son, go back to the bedroom and start all over again. After NG for several times, the math class finally began.

"Today, we are going to talk about numbers. For example, this is a bead, and it is 1, which means' bit'. " The son held out his little hand, pointed to his little finger and said, "Further up is 2, 3, 4, 5, 6, 7, 8, 9." He pointed to the ring finger and the middle finger and counted them. "Attention, it's running out of names!" I sat squarely on the sofa, listened carefully and opened my eyes wide. Watching my son imitate Mr Fang's tone made me want to laugh, but I still tried to listen carefully. "Note, after 10, it should be renamed and become a' ten' bit". 10, 20, 30, 40, 50, 60, 70, 80, 90, 9 1, 92, 93, 94, 95, 96, 97, 98, 99. Note that there will be no name soon. "

I reached out and made a statement. "Du Jinyao classmate, what's your problem? Teacher, how many are 10? What are the largest single digits and the largest ten digits respectively? Oh, 10 1 is ten, the largest single digit is nine, and the largest ten digit is 99. The teacher thought for a moment and answered quickly. It seems that he listened carefully in class.

"What post should I change after 1999?" The student asked.

"After 1999, it is one hundred, 10 ten is one hundred,100,200,300" "I'll count!" My son and I counted "400,500,600,700,800,900." What should be after 900? I asked again.

"After 900, it is 90 10/0,9020." I stared at the teacher. He thought for a moment and said, "Oh, no, it's 9 10, 920, 930, 940, 950 … 990, 99 1, 992 … 999.

When I heard my son say "I lost my name again", I couldn't help laughing again. Did the teacher say that? I haven't had a class, but I think he knows what it means. It's time to switch places. "Teacher, where should I change?"

"This time, it became a thousand, 1000, 20xx ... 9000, 9100, 9200, 9300 ... 9900, 9910, 9920, 9930 ... 9990. It seems that this teacher is really enjoyable.

"I have to pay more attention in the future and want to change it to' 10,000'." The little teacher spoke again.

"Oh, how many zeros are there behind ten thousand teachers?" My little teacher pulled out her finger and said to me, "There are four zeros, one, ten, a hundred, and that 1 is ten thousand." I smiled with satisfaction.

"Is there another one after that ten thousand dollars?"

"Of course, you can treat ten thousand people as one, and there are hundreds of thousands, millions, and ..." The little teacher scratched his head, as if he couldn't remember them together. "Oh, teacher, I know, there are tens of millions. Oh, great! It's' 10 million' and then' 100 million'! Wow, what a big number! You know so much! Thank you, teacher, for teaching us so much. "

Our little teacher smiled shyly, looked up and said proudly, "Oh, I know so much!" "

A math class ended in laughter.

My family is a "math" family, not because everyone in my family is proficient in numbers, but because my relationship with my parents can be expressed by some mathematical formulas. Generally speaking, "I = father+mother", because I am the son of father and mother, not only have similar appearance, but also inherit their strong and unyielding character. Although I am a nobody, I am really a member of the family. My parents treat me equally. When I meet things at home, I will be honest with each other, just like a little host.

So, sometimes "my father+mother". Do you know why? Because when my parents were doing farm work, they saw something was wrong, so they discussed with me and asked me how to deal with it. They did as I said. At this time, I feel that I am a teacher and they are like students.

Our family is such a veritable "home of mathematics".

Sixth grade math composition 3 Dear math teacher:

Hello!

I don't know how you are recently. Are your muscles comfortable? Is your throat comfortable? Don't be too tired.

You sacrifice yourself like a candle to illuminate others; Like a loving mother, you care about me in every way; Like a gardener, you have cultivated me diligently.

In my impression, you will always be great. Yes! You have done too much for us, and we have done too little for you. You are like a bright lamp, leading us to swim in the ocean of knowledge. Let us know: the truth of being a man. You are fair and just, poor students make progress and praise, and excellent students make wrong criticisms-ah! Teacher! You moisten our hearts like spring rain, and let us know the direction of progress before entering middle school.

I remember once, you had a sore throat and couldn't speak, so you wrote to us by hand. Teacher, you were ill and came to class with illness, so you caught up with your homework, but your illness delayed you. Looking at your tired and busy figure, I can't help being proud of having such an excellent teacher.

Teacher, we love you forever. You are our good teacher! Here, I am very grateful to you, thank you for your concern and love for me! I want to say to you loudly: teacher, you have worked hard! Thank you!

I wish you:

Good health! You did a good job. All the best!

Your student: Shi.

20xx February 2 1

Unconsciously, two weeks passed. As a graduating student, I can't help feeling deeply. Everyone is persistent in doing one thing-keep writing a weekly diary! This is good for everyone. It can not only help you consolidate what you have learned, but also exercise your writing ability. Looking back on my study and life a few days ago, I can't help but benefit a lot. After a week's study, we learned the knowledge of finding the lateral area, surface area, volume and volume of a cylinder. Let's recall what we have learned again! First think about the name of the cylinder: the upper and lower surfaces of the cylinder are called the bottom surface of the cylinder, and the surface surrounded by the cylinder has a curved surface called the side surface of the cylinder. The distance between the two bottom surfaces of a cylinder is called the height of the cylinder. By expanding the side of the cylinder, a rectangle can be obtained. The length of the rectangle is equal to the circumference of the bottom of the cylinder, and the width of the rectangle is equal to the height of the cylinder. In this way, we can easily see that the lateral area of a cylinder is equal to the perimeter of the bottom multiplied by the height.

How to find the surface area of a cylinder? Spread all the surface of the cylinder, then we can see that it is like a division symbol, and the surface area of the cylinder is equal to the lateral area of the cylinder plus two bottom areas. Next, I have to do the problem again, and I need a very troublesome cylindrical area. Alas, it is not easy to find the surface area. We need to find the bottom area and the side area, and then add them up. If we are not careful, we will make mistakes. Is there any good way to put it all together? I was thinking. Look at the bottom area and lateral area's formula!

S-bottom =πr2, which has two bottoms, namely 2πr2. Let's look at lateral area's formula: S-side =2πrh, add them together, extract the similar term: 2πr, and form a new formula: S-table =2πr(r+h) by using the law of multiplicative association. A new formula was born. With this formula, only phase is needed.

Eat it once and you'll be fine!

I used a formula to find the area of a ring: s ring =π(R2-r2). Come to think of it, this is actually a combination of formulas! Subtract two circles, extract π and * * *, and get a new formula.

The birth of these new formulas is attributed to flexibility and laziness! If it was not too much trouble, there would be no such formula. In fact, it is also important to use the formula flexibly. Sometimes, the questioner steals a lazy person and misses a condition, so we can ask for more. However, we need to be lazy in some places, and we can't be lazy.

There is a problem: there is an inscribed circle in a big square, and the area of the big square is 20 square centimeters. Find the area of a circle.

According to common sense, we should first find the side length of a big square, which is D, then R, and finally the area. However, in this problem, how can we find R&D? Unless a prescription is prescribed, it will be troublesome and will certainly be inexhaustible. What should I do? At this time, it is necessary to use the formula flexibly. Since the area formula of a circle is πr2, it is ok to find r2 instead of R! At this time, we can regard it as a whole a, that is, we only need to find aπ. How to ask? The area of a square should be (2r)2, which is 4r2 after simplification, that is, 4a. So we can use 20÷4=5(cm2) to find a, and then use 5×π≈ 15.7(cm2). The area of the circle is about 15.7cm2, so the area of the circle aπ can be solved without roots. Many formulas can be combined with each other to form a simple and practical new formula. As long as we innovate, we are actually kneading the steamed bread eaten by the giants into a ball and making new rolls. Is this not good?

Since ancient times, which talented student has not been trained by teachers! So the teacher is selfless, I want to cheer for the teacher.

Our math teacher is a female teacher, with a square Fiona Fang round face, slender eyebrows like wicker, long blond curly hair and a pair of intense eyes, which looks very beautiful against the gorgeous clothes.

Her teaching method is also very special. Every time in math class, she tells us a joke, which makes us laugh from ear to ear. Or when a classmate copied her homework, she told us the truth of being a man in class the next day. She usually gives us lessons with a smile. I am glad to have such a teacher to teach me. Because her class can bring me fun, let me listen carefully in class and make no small moves.

Once, she still walked into the classroom with a smile. The students are not as happy as before, because they just passed the exam yesterday and are very worried! At this time, the teacher said to everyone,' Students, the exam is just a test of your study.' Do you think you will make progress if you flinch in the face of this small difficulty? Cheer up. When the students heard this. Suddenly, the dull breath became cheerful. Open your eyes and listen to the teacher, one by one, for fear of missing a word.

Our math teacher is like our second mother. She will help when she is in trouble. Give me encouragement and strength.

Sixth grade math composition article 6 "There is a new math teacher in our class!" "The math teacher in our class is Miss Feng!" The latest news made us very happy. Because I have long heard that this teacher Feng teaches well, it is great to teach our class this time.

Teacher Feng really lives up to her reputation and teaches very well. Every time she attends class, a little joke pops up from time to time. Everyone in Doby makes boring math classes interesting.

Hey! You will ask, "Does Mr. Feng like his works?" Not to mention this: every morning, Mr. Feng takes the notebook of the classmate who did the wrong question yesterday and goes to the classroom to call them to the front and explain them one by one until the classmates can do it.

Teacher Feng is very kind and never hits anyone. She often said, "I am like the Monkey King, and you are like a monkey. The Monkey King has such a good relationship with them. How could he have the heart to hit them? " You will ask, "If someone does a small thing, will Mr. Feng care?" Don't worry, Mr. Feng will reply like this: "Mr. Feng's eyes are very picky, and nothing can be hidden from the teacher's eyes." After that, Mr. Feng glanced at the classmate again. If you see that your classmates are still playing tricks, Mr. Feng will move the chair out from under the table and say to your classmates, "Classmate, I will show you a sketch. Please don't laugh. " Later, the teacher learned from this classmate's appearance: head down, hands groping around, this classmate saw it, and immediately knew that the teacher was learning his own appearance, so he quickly put things away and listened to the teacher carefully. Students, you see how wonderful Mr. Feng's move is. It not only disgraces the classmate, but also makes him stop making small moves.

After class, the students gathered around to discuss the teacher: someone said, "Teacher Feng treats us as friends, so we should listen carefully." Someone said, "I thought Miss Feng was fierce at first, but I didn't expect her to be so kind and warm my heart." Someone said, "Mr. Feng smiled as soon as he entered the door, which made me feel refreshed at once." Someone said, "Teacher Feng's smile touched me. I must study hard and make progress every day. " Others said it was ┉ ┉.

Students, would you like to meet our amiable and humorous math teacher?

Because I like math very much, and I also like to sum up some rules to help me improve my interest in learning math, so I want to share with you the math I found in my life, so as to improve my math level and let myself go up a storey still higher.

Learning mathematics is to apply it in real life. If you learn math well, you can save a lot of money by shopping in your life! For example, when we buy ham sausage, have we ever thought about buying it in retail or packaging? In fact, if you do the math, you can save a lot of money a year.

. If you buy 10 pieces for retail, each piece is 40 cents, and ten pieces are 10×4 = 40 (cents), which is equivalent to 4 yuan. A pack of ten pieces is only available in 3.7 yuan, which is 3 cents cheaper than retail! This year is 3×365= 1095 (coke), which means that you may save 109.5 yuan a year! Another example: If you drop 3600 drops of water an hour, one day is 3600×24 = 86400 (drops), and one year is 86400×365 = 3 153600 (drops). Wow! It's really "I don't know, I'm shocked". The water resources on the earth are gradually lacking, so we should save water. Especially when washing clothes, it takes the most water. With the same amount of water, some people can clean their clothes, while others can't. Why is it different?

Let me give you an answer: suppose the dirt on a dirty dress weighs 10g, and there is 10l clean water in1g. After the clothes are wrung out, there is still 1l water in the wet clothes. J. Pour 65,438+00g of dirt and 65,438g of clean water into the basin. Because there is still 1 liter of water on the clothes after wringing, this 1 liter of water also contains 1 gram of dirt. This means that the washed clothes contain 1 g dirt; K Divide 10 liter of water into two pots, each pot is 10÷2=5 (liters). Wash in the first pot, with10g dirt and 5 liters of water, each liter contains 2g dirt, and then wash in the second pot, with 2g dirt (contained in clothes after the first wringing) and water. From the above inference, we can easily see that the clothes washed by the second method are cleaner and save a lot of water. If each of us does this, the whole country can save a lot of water, so we won't worry about water shortage. Looking closely, we also have "mathematics", such as our hands, "one?" Yes 10 cm. Is it 6 when measuring pants? That is, 6× 10=60 (cm) long; Our steps are 50 cm, so how many steps are there from home to school, we can find out the distance from home to school.

With so many typical examples, I think of an old saying: "Experience without learning is better than learning without experience!" . Yes, you can't learn math by rote. You must learn and apply what you have learned. Therefore, in my future study, I must be strict with myself in by going up one flight of stairs. If I can't, I will try my best to be right, make full preparations for my future academic development, lay a solid foundation, and strive to become a pillar of the motherland.

Today, my aunt was in high spirits when she was playing games online. Suddenly, she found it cheaper to buy clothes online. Then, my aunt said to me, "Ningning, come on, watch 50% off online shopping or full payment?" 50% off the court! Also, 300 yuan is enough to buy things online, and 300 yuan is sent. Do you think this is a good deal? "

I said, "Aunt, I haven't learned anything about discounts. How should I know? " Menstruation said, "Hey, I remember your sixth grade, right? It's in the math book, go and have a look. " I said, "Oh." I didn't know until I read it. A few discounts are only a few tenths of the original price, that is, dozens of discounts. I also know that if we want to calculate the discount price of goods, we have to multiply the original price by the discount and so on. Yu? Current price. Menstruation asked me, "The original price of this dress 156 yuan is 50% off. How much is it? " Without thinking, I said, "The original price is 78 yuan." My aunt was surprised and said, "Ningning, are you self-taught? I think so. " I said, "This is very simple. We use the original price × discount = current price, so we use 156× 0.5 = 78 yuan. " My aunt said, "Where did you get 0.5?" Once again, I said without thinking, "50% off is 50% off, and turning 50% off into a decimal is 0.5." ? I was right.

There is a lot of math knowledge around you, depending on whether you pay attention or not.

The sixth grade math composition 9 is Wednesday again, and it is also a math interest activity class. The teacher came into the classroom, tidied up the things on the platform and said to us, "Today, let's see a magic trick." Ah, why magic? I hate magic very much, because I think magic is actually hiding and having no knowledge. Why should we watch magic in math activity class? At this time, the teacher answered our doubts-this is mathematical magic! As soon as we heard it, we got excited and stared at the video with rapt attention. ...

The video begins to play. I saw the magician standing behind the desk. He drew 27 cards from a deck of playing cards and called an audience. The magician washed 27 cards and asked the audience to draw one. The magician told the audience to remember this card by themselves, not to show it to him. When I looked intently, it was 7 of hearts. Then the magician asked the audience to put the cards back. He skillfully shuffled the cards and asked the audience, "1 to 27, which number do you like?"

The audience thought for a moment: "10."

"Good number." The magician nodded and shuffled the cards. "Now I'm going to divide these 27 cards into three stacks one by one from left to right. After that, you tell me where the cards you drew are stacked. "

The magician first puts 1 card on the left, then 1 card in the middle, then 1 card on the right, and then deals cards on the left, middle and right ... everyone faces up. After the cards were dealt, the magician asked, "Where is the pile of cards you drew?"

"In the middle stack." The audience said.

The magician turned all the cards upside down, stacked them one by one, and then continued to divide them into three stacks. He repeated the actions and questions just now. This was repeated three times. The magician took the card and said, "You just said that your favorite number is 10, right?" "yes." "Now, I count this stack of cards from top to bottom, and the number you like is the card you drew."

I was very surprised to hear this sentence. The magician doesn't know the cards drawn by the audience. This has nothing to do with favorite numbers! Can he really find the card? I don't believe it.

I saw the magician counting from top to bottom, "1, 2, 3...9, 10! "The magician opens the card of 10, and it really is 7 of hearts! The whole audience was shocked, not only the audience, but also the people in our math class! What's the mystery in this?

The teacher saw our doubts and continued to play the video. Then the magician began to answer our doubts. It turns out that this magic really has a lot to do with mathematics and the median we have learned. The key point of this magic trick is that the magician constantly calculates the position of the card drawn by the audience with the help of the card. ...

My deskmate and I can't wait to start. Haha, it worked. Now, I like magic, especially math magic. If you want to learn this trick, you can contact me!
