2022 open science class explains mathematics and computing technology. How to write the composition of open class mathematics and computing technology? The following is a paper on 10 public course Mathematics and Computing Technology for reference only. Like to collect and share!

During the summer vacation, my mother saw a math game from the book, which can help us calculate quickly. Therefore, my mother suggested that I often play this game.

The rules of the game are as follows: Prepare two decks of cards, and then take out GREAT GHOST and Xiao Gui. Remember: J, Q and K represent the numbers 1 1, 12 and 13 respectively. The first time you play cards, you need to add up the whole card. After calculating the correct number,

When drawing cards, we draw cards from each other, put the drawn cards aside to prevent peeking, then add up the remaining cards, and then subtract the calculated number from the total number of cards in a deck to calculate how many cards have been drawn.

When I play with my mother, she always calculates faster and has higher accuracy than me, so I get experience from her. My mother said, "When counting cards, I mainly concentrate on mastering certain operation rules." I did as my mother said, and I really calculated the game quickly and accurately. It seems that mom knows a lot!

I suggest you try this game, because it can improve our calculation speed and make us like math!

Recently, I suddenly found myself in love with the subject of mathematics.

In recent math class, I often raise my hand, and the teacher often asks me to answer questions. Moreover, my answer is particularly detailed, and the math teacher hardly needs to give any more lectures, but only adds a little. This may be a sign that I love mathematics.

Every Saturday, I think math class is boring, but after discovering the fun of math, I become more serious in class and think better when I go home to do math homework. When I am free, sometimes I will challenge some math problems. Academic performance has also improved, and homework performance has changed from b+ and a- at the beginning to A and a+ now. The test scores ranged from 75-90 at the beginning of this school to 1 15- 120 (full mark 120), which made me feel very enthusiastic about mathematics. I have completely fallen in love with mathematics, and it also makes me feel a sense of accomplishment.

I love math, and math will make progress. I was selected by my class to participate in the "Qiaoyuan Cup" competition and won the prize. After winning the prize, my classmates also admired me and my teacher praised me. I feel much more confident. These awards are all proof that I love mathematics.

Math, I love you.

Mathematics and Computing Technology Composition 3 "Today's math homework is sixty-three to eighty-one, and the math workbook goes back to the third time." Every day, the teachers who love and respect mathematics in our class will stipulate some math homework that will make us study all night, which will make me want to cry.

I'm really curious who will like the subject of "Mathematics" and why there is such a thing as "Mathematics" in the world. The subject that bothers me most is mathematics, so I hope that "mathematics" will disappear in my life on the surface.

What exactly do we need math for? In addition to addition, subtraction, multiplication and division, braces, brackets, four operations, speed, two sum problems, chicken and rabbit problems. We are not farmers, why should we know about chickens and rabbits? We don't need to drive now, so why do we need to know the speed? How much do these formulas have to do with our lives? Who can tell me?

A lot of mathematical formulas don't exist at all, but my life is troubled by them every day, so I want to shout: "Mathematics has disappeared! Don't appear again! "

My math teacher is a woman teacher. She seldom takes charge of other classes and often helps us solve math problems. She is a very caring person and loves our teacher very much. But we are in the sixth grade and will leave this dear teacher.

I still remember one time a classmate wrote on the blackboard: Chen Jiaxing is an idiot. The teacher was very angry. The teacher asked, "Who did this?" . When none of the students admitted their mistakes, Mr. Huang flew into a rage and then doubted Gu Yi. Gu Yi said, "I didn't write it." The teacher said, "Who else but you, the classmates who usually make trouble?" Say that finish, just pull the ancient meaning to the front desk to play, too cruel! In this way, Mr. Huang had a lesson in the multimedia room.

Will leave our dear math teacher! What shall we do? I wanted to leave this school quickly. Why don't I want to leave now?

You're leaving the teacher. Why don't you give the teacher a good impression? Think about the good old days.

I hope I can get good grades in China Normal University ... Thank you teachers.

Mathematics and Computing Technology Composition 5 in Open Science Course Today, the teacher assigned us a practical assignment to draw corners with a triangular ruler. How many kinds can you draw?

There are angles of 90 degrees, 60 degrees, 30 degrees and 45 degrees in the triangular ruler. I put it together with a triangle, and quickly spelled out the angles of 75 degrees, 90 degrees, 105 degrees, 120 degrees, 135 degrees and 150 degrees in turn. However, is this all? I kept fiddling with that triangle again. Suddenly found that 45-degree angle and 30-degree angle overlap and there is a new angle, which is obtained by subtracting the two angles on the triangle. I quickly figured out that the angle was 15 degrees! At this time, I suddenly realized that spelling is not only the addition of degrees, but also the reduction of degrees when spelling inside!

At this time, my father came over and asked me, how many corners have you spelled! It's amazing! Can you tell me the rules of these corners? After listening to my father's words, I lost in thought again. 15, 30, 45, 60 ...180, these are all multiples of15! It turns out that the angles spelled by triangles are all multiples of 15 degrees!

It seems that corner spelling hides a lot of math problems! After this practical work, I know that learning mathematics is not only to complete the task, but more importantly, to observe, think and learn more knowledge in the practice process!

I hate math and fell asleep when I was doing my math homework.

When I woke up, I found myself in a place I had never been before. I raised my curious head and saw the Chinese characters embedded in Jin Guangzhong-the country of mathematics.

I walked in curiously and saw a playground. I rushed over. I saw a huge billboard. Mathematical roller coaster, ticket price: doing a difficult Olympic math problem. IQ: Don't play below IQ 100! I thought: I hate math! I ran away immediately.

I saw a huge Ferris wheel again. Ha! I like playing ferris wheel best. I rushed at the speed of light. I saw a billboard. It says, Ticket: Make a question about the circle. IQ: Don't play under 50.

I am sweating! Why math again?

I don't want it! Don't! ……

"Ah" I woke up from my dream! After that, I don't hate doing math problems anymore!

When I was in primary school, my math scores were always poor. I haven't tested 100 since the third grade. For this reason, my mother worried about me for a long time, invited a tutor and took an interest class, but it was useless. What should I do? Cold salad! Who says I have no talent for mathematics? Call me benzene! But I got the first grade in Chinese, saying that I am not smart, but I can learn it as soon as I learn to draw. ......

But this can't blame me, because my parents have no math cells and can't eat a fat man in one bite. Don't worry ... but my mother doesn't want to train me to be a great mathematician like Hua. Isn't this forcing me? ! My mother made a determined effort to change all my extracurricular books into math books, forcing me to "eat". Students lamented: "cherish the male armpits! Humble, stupid, sorry, burping, resisting alfalfa

When I see math, my head gets bigger. When I was doing my homework, my mother was watching soap operas, but when I picked up my math exercise book, my mother came out of nowhere and looked at my exercise book! I'm scared! Because I can't use a calculator!

At noon today, a sudden news-the second mid-term exam in the afternoon broke my interest in playing, so I immediately reviewed.

Finally, it's time to hand out the papers, and my heart is pounding nervously. It's really fifteen bamboo baskets that draw water with nothing-I'm in a hurry.

I turned over the test paper and didn't read much. I think the topic must be very difficult. I took a deep breath and began to "work hard" ...

Finally finished, I looked at my watch, and there were 10 minutes left, so I relaxed, wiped the sweat on my hands and started the inspection again.

After several visits, most of them are fine, but there is one question, the answer of which I am not sure. In the mathematical masterpiece Nine Chapters Arithmetic, there is a method to find the greatest common factor, which is called ().

Rarer, more damaging. B, the division over and over again. C. short division.

I thought about it and chose the modern name: short teacher. But just then, the bell rang. I handed in my test paper at once and checked it. I found the answer is a! But it's too late to regret it now, and we have to work hard next time.

Today's tense exam is over. I went home happily with a flower umbrella.

I like math very much because it is made up of many interesting numbers. These figures seem simple and boring, but you don't know there are many interesting places in them!

One day after dinner, my mother and I went for a walk in the park. We saw three grandmothers in the park. They are in high spirits and chatting in the park. I went to know their age, so I made a phone call first: "Hello grandmothers!" " "Ask them how old they are. Instead of answering directly, the old people picked up a branch and wrote a word on the soil. One of them writes "Ben", one writes "End" and the other writes "White". I was at a loss for a moment and couldn't guess grandma's age.

When I got home, I asked my mother. Mother said, "Look at these words carefully and think about their relationship with numbers." After thinking about it, I finally found that "Ben" and "Mei" can be divided into eight, ten and one, so two of them are 8 1 year. The other "white" is a hundred words short of one, so the other grandmother is 99 years old. Mom praised me for being so smart! I like interesting numbers and interesting math.

I remember when I was in primary school, my math score was still very good, and I was ranked at the top of my class every time. I also like learning math very much, especially when it comes to the math exam, I will be particularly excited and want to get a beautiful score for my mother to praise me.

But it didn't last long. When I was in the fifth grade, I don't know why, my math scores suddenly fell, which was very serious. Seeing that my grades are not as good as the last one, I feel very uncomfortable, and full of frustration has occupied my heart. So slowly, I have a fear of mathematics. Every time I take a math exam, I always feel very nervous, afraid that I will get another unsatisfactory score, which will lead to results again and again.

Later, our math teacher came to me and carefully analyzed the reasons for my decline in math. It turns out that sometimes I don't understand a small knowledge point, but the knowledge points behind it are closely related to the previous ones, which leads me to fail to understand the meaning of a concept.

After the teacher's analysis and my hard work for a period of time, my math scores picked up again, and I became friends with math again.
