Speech before math class 1 Learn math like fishing; Solving a problem is like catching a fish; From this, we have mastered a method of doing the problem, just like having a fishing net, even the most difficult problem can be successfully broken through! Therefore, whether you can learn math well depends on whether there are fish or nets. Have you ever solved a problem, or a golden key to open the door to mathematics!
In fact, it is not difficult to learn mathematics, mainly because you can be good at practice and thinking. As the saying goes, "Practice makes perfect". In our daily life, we should observe and discover more, and then you will know that mathematics is around us. The purpose of learning mathematics is to apply it to real life. Mathematics is used by people to solve practical problems. For example, when shopping on the street, it is natural to use addition and subtraction; Building a house naturally requires geometry; It is natural to look at the time with the 24-hour time method ... There are countless such problems, and all these knowledge are generated from life, and finally summed up as mathematical knowledge, which solves more practical problems.
Now, I consciously associate mathematics with my daily life. Found a lot of mysteries and fun about mathematics. Once my mother baked pancakes, and only two cakes were put in each pot. I think it takes two minutes to bake a cake, one minute on each side, two pancakes in the pot at the same time, and at least a few minutes to bake three cakes. Back in the study, I calculated and came to the conclusion that it takes 3 minutes: first, put the first cake, the second cake and the third cake into the pot at the same time. 1 min later, take out the first cake, put in the third cake, and turn the second cake over; Bake for another minute and the second cake will be ready. Then put the reverse side of the first cake in, and turn the third cake upside down at the same time, so it will be ready in 3 minutes. I told my mother what I thought, which really saved me a lot of time. Time is life! It turns out that learning mathematics also has the advantage of saving time! Deep, too deep!
Mathematics should be studied in life. It is inseparable from life. If you study thoroughly, you will find math very useful. Geometry in mathematics is also very interesting, especially the strangest "circle" in geometry. The formula for calculating the area of a circle is S=r2. Because the radius is different, the area of the circle is also different. For example, is a circle with a radius of 9cm equal to a circle with a radius of 5cm? First, we use the area formula to find the area of two circles, which are 254.34 square centimeters and 78.5 square centimeters respectively. The radii of the two circles are different, so the areas of the two circles are also different. If the radius is long, the area is large; Short radius, small area! With this rule, I will definitely do the problem in the future!
Mathematics is like a mountain, towering into the sky. When we first started climbing the mountain, we felt relaxed, but the higher we climbed, the steeper the mountain became, which made people feel scared. At that time, only those who really loved mathematics would have the courage to continue climbing, so those who stood at the peak of mathematics loved mathematics from the heart. Remember, people who stand at the foot of the peak will never see the peak! If you love math, you can learn it well!
Speech before math class 2 Dear teachers and classmates:
Hello everyone!
I believe that mathematics is a subject that makes many people have a headache. However, learning mathematics is not helpless. As long as you master the right methods, you will certainly learn mathematics well. Next, I will talk about my heart, hoping to help everyone.
First, pay attention to the lecture in class and review it in time after class.
If you want to learn math well, you should follow the teacher's thoughts in class, finish your homework independently after class and be diligent in thinking. For some problems that are difficult to solve for a while because of their unclear thinking, let yourself calm down, seriously analyze the problems and try to solve them by yourself.
Second, do more questions appropriately and develop good problem-solving habits.
If you want to learn math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various questions. For some error-prone topics, you can prepare a set of wrong questions, write your own problem-solving ideas and correct problem-solving processes, and compare them to find out your own mistakes so as to correct them in time.
Third, adjust the mentality and treat the exam correctly.
If you want to learn math well, you must adjust your mentality, calm yourself down at any time, think in an orderly way and overcome impetuous emotions. In particular, we should have confidence in ourselves and encourage ourselves to overcome difficulties.
It can be seen that if you want to learn mathematics well, you must find a suitable learning method, understand the characteristics of mathematics and let yourself enter the vast world of mathematics!
Speech before math class 3 Dear teachers and students:
Hello everyone!
I remember when I was a child, when I came back from kindergarten, my mother always asked me to count how many people in my family ate, how many hands and how many legs I had today. Later I learned that my mother taught me math.
After entering the school, I found that mathematics is a very interesting course. No need to carry it. As long as you listen carefully, master its rules, use it flexibly and calculate carefully, you will certainly get good results.
I remember that I got 100 in the final exam of the third grade of last semester, and I was the first in my class. I was very happy and proud. By next semester, I thought I had a good foundation, so I stopped studying hard. I only got more than 80 points in the final exam. My mother knew, and instead of scolding me, she sat down and patiently said to me, "Do you know why I didn't do well in the math exam? It's not that you won't, it's that you underestimate your enemy! Mathematics is not as simple as you think, it needs your flexibility and seriousness. " After listening to my mother, I bowed my head.
In the blink of an eye, in the fourth grade, mathematics becomes more and more difficult, from simple one-digit addition, subtraction, multiplication and division to three-digit division and mixed operation. I just know that it is not easy to learn anything, but I am a careless king, and there are always some calculation mistakes in my homework every day, not to mention the exam. Take this mid-term exam for example, I am fully capable of getting full marks. Because of a calculation error, alas!
A parent-teacher conference was held the other day. My mother didn't put in a good word like last time. When she got home, she said with a straight face, "If a person keeps making the same mistake, it's not that he is careless, but that he doesn't care. No matter math, Chinese or English, you must study hard and have a good learning attitude in order to have a good performance! " I am ashamed to hear that.
I promised, "Don't worry, Mom. From now on, I will definitely remember your words and improve every subject. Believe me, I will give you a satisfactory answer in the final exam! "
Mathematics is my favorite subject, and it must be my strong point!
Speech before math class 4 Dear XX:
The most promising winner is not a talented person, but a person who makes good use of every opportunity-Socrates. This famous saying explains the relationship between hope and time. Hope is not empty talk, let alone fantasy. At home, we should do some housework for our parents. At school, we should spend time studying. In our alma mater-No.3 Middle School. Full of this atmosphere of serious study.
No.3 Middle School is our alma mater. In No.3 Middle School, the most famous one belongs to the ginkgo tree in the Southern Song Dynasty. That ginkgo tree, like a giant, watched the students in our No.3 Middle School come and go in batches. Touching the "trunk" of ginkgo tree, I seem to be in that era of war and development.
The third middle school is very old. Every tree, every building and every room reveals that it has a history of one hundred years. It is young, and there is no worldly noise and disgusting garbage here. It exudes antique, and with the dance of Hua Die, you can smell a quiet and fragrant young world.
The school is like a big family. Teachers are like amiable elders, and classmates are close brothers and sisters. If there is no teacher, we will lose our direction and deviate from our course; Without classmates, it is like losing the sunshine in life and the laughter in joy. Everyone's party makes our life more exciting. There are glorious moments in life, which is also the starting point for us to meet the society. Then, we should hold hands and win glory for our alma mater.
Singing and laughing under the ginkgo tree is our youth, and we are full of enthusiasm here; Learn self-esteem, self-confidence, self-improvement and self-love here, and then strive to acquire knowledge with our full spirit and boldly deal with countless difficulties and hardships in the future. We shouldn't be afraid. The road may be long and tortuous, but when you are strong in your heart, you can be brave.
Everything we have experienced in No.3 Middle School will become brilliant fireworks in the night sky in our future memories. Although short-lived, it can leave eternal beauty in our lives.
I believe that when we step into the society one day, no matter who will think of it, the purest and best memories of our life are left under the ginkgo tree.
Thank you!
According to the age characteristics of students in this grade, I made a "three minutes before class" training plan. Details are as follows:
First, the theoretical basis of training
(1) advocate * * * participation. The "three minutes before class" training requires everyone to participate, which provides a place for every student to fully display their equal opportunities and display their talents. When students experience the fun of Chinese from participation, they will gradually change from passive to active, from "asking me to do" to "I want to do" and finally achieve "I can do it".
(2) enhance competitiveness. Benign competition can greatly enhance students' learning desire and motivation. When listening to other people's speeches, students can learn knowledge and get inspiration, thus stimulating their desire to improve their comprehensive ability and compete with others. When students put this desire into practice, they will be trained and their talents will be increased. In this sense, "competition is a silent mentor".
(3) Propagandize the uniqueness of innovation. In the "three minutes before class" training, we should follow the principle of "no one has me, no one has me, no one has me, no one has me, no one has me, no one has me, no one has me, no one has me". Encourage students to express their unique views. This idea of innovation and seeking differences can promote students to acquire more and richer knowledge, improve their comprehensive ability and increase their talents. Only with innovation can talents continue to develop and progress.
(4) Follow step by step. "Three minutes before class" training, divided into several rounds, from easy to difficult, gradually to the degree of "difficult", in line with the principle that people's cognition of things is gradual. If you train at will regardless of the difficulty level, or increase the difficulty at once, it is not in line with the principle of gradual progress, and it is difficult to receive the expected results.
Second, the training plan
The training of "three minutes before class" should be diversified, the genre of speech should be unlimited, the content and theme should be self-determined, and students should be given full freedom to play, with few restrictions, which can not only stimulate students' interest, but also satisfy their psychological desire for individual freedom, and often make the training more effective. Students can tell real math stories about themselves, people around them and celebrities, or write exercises and so on.
Third, the benefits of training.
(1) The activity time is short and the benefits are wide. The training time of "three minutes before class" is not long, which generally will not affect the completion of teaching tasks in this class. And every student has to participate, and the students in the class have to train. It satisfies every student's desire to show their talents to others, provides opportunities and platforms for students to exercise themselves and fully show themselves, and promotes mutual learning and competition among students.
(2) The training burden is small and the results are great. "Three minutes before class" training, it takes about two months for each student to take turns to train. Although it takes some time and energy for students to prepare carefully in advance, it is not important for each student to prepare only three times a semester. After a long time, students' oral expression ability and thinking innovation ability have been improved, which is of great benefit to students to engage in various activities in society. In particular, evaluation and appreciation of training have the most obvious benefits for students. Not only the students who speak have improved their ability, but also the students and teachers who listen have benefited a lot, which can improve students' ability to think from multiple angles. Moreover, after each student's training, the applause of other students can arouse the enthusiasm of the whole class and create a good emotional atmosphere for each math class.
Speech before math class Dear teachers and students:
Hello everyone!
The cold winter quietly left, and Miss Chun came to us in soft gauze. She sprinkled a little dew and moistened the world and the earth. Everything in the world absorbs nectar and thrives. In the woods of sasha vujacic, sasha vujacic, a young musician, Miss Chunyu, is playing music in the green and whispering for the sleeping bamboo shoots. The shoots of bamboo shoots woke up and emerged from the ground. They opened their eyes and looked, oh, how beautiful! Peach blossoms are crimson, green branches are dancing and green braids are dancing, and birds are chirping in the trees. Isn't all this just a report to hibernating animals that spring has come?
In the field, there are blooming flowers everywhere, and the fragrance of flowers is refreshing, attracting groups of bees to dance on it. In the field, the wheat seedlings are rippling and the rape blossoms are Huang Cancan. Under the caress of Miss Feng's little hand, they fall into English from time to time. A group of little girls who love beauty came to the flowers, picked bright flowers and put them on their heads. You smiled at me and the flowers blushed. It's really beautiful.
You see, that open river is like thousands of silks and satins blown by the wind. The fish in the water are in droves, foaming slowly and wagging their tails to play. The ducklings are swimming in the water, sometimes diving into the water and sometimes surfacing. In order to express their joy, they sometimes lead their necks to sing, as if singing: "Spring is coming!" " No wonder the ancient poem goes: "Spring River Plumbing Duck Prophet."
"A year's plan lies in spring". On the edge of the field, farmers' uncles are trying to loosen the soil, sow seeds and water.
What an infinite spring! The beauty, simplicity and tranquility of this natural world are refreshing. I hope the "spring" in my hometown will always be there! I hope that our great motherland has the light of "spring" everywhere! Spring is infinitely good!
Speech before math class 7 Hello everyone, I'm XXX, and I believe that math is a headache for many people. However, learning math is beyond your power. As long as you master the correct method, you can learn math well.
First, pay attention to the lecture in class and review it in time after class.
If you want to learn math well, you should keep up with the teacher's ideas in class, finish your homework independently after class and be diligent in thinking. For some problems, it is difficult to solve for a while because of unclear thinking. We should calm down and seriously analyze the problems and try our best to solve them ourselves.
Second, do more questions appropriately and develop good problem-solving habits.
If you want to learn math well, it is inevitable to do many problems, so you should be familiar with the thinking of solving various problems. For some error-prone problems, you can prepare a set of wrong questions, write down your own thinking and correct the problem-solving process, and compare them together to find out where your mistakes are, so as to correct them in time.
Third, adjust the mentality and be positive.
Take the exam seriously. If you want to learn math well, you must adjust your mentality, calm yourself down at any time, think in an orderly way and overcome impetuous emotions. In particular, we should have confidence in ourselves and encourage ourselves to overcome difficulties. It can be seen that if you want to learn mathematics well, you must find a suitable learning method, understand the characteristics of mathematics and let yourself enter the vast world of mathematics!
Speech before math class Section 8 Dear teachers and students:
Hello everyone!
Learning math is like fishing; Solving a problem is like catching a fish; So, I have mastered a way to do the problem, just like with a fishing net, even the most difficult problem can be successfully broken through! Therefore, whether you can learn math well depends on whether you have fish or nets. You have solved a problem and still have a golden key to open the door to mathematics!
In fact, it is not difficult to learn mathematics, mainly because you can be good at practice and thinking. As the saying goes, "Practice makes true knowledge". In our daily life, we should observe and discover more, then you will know that mathematics is around us. The purpose of learning mathematics is to apply it in real life. Mathematics is used by people to solve practical problems. For example, when shopping on the street, it is natural to use addition and subtraction. Geometry is naturally used to build houses; It's natural to look at the time by 24-hour timing ... there are countless such problems. This knowledge is generated from life, and finally summed up as mathematical knowledge to solve more practical problems.
Now, I consciously associate mathematics with my daily life. Found a lot of mysteries and fun about mathematics. Once, my mother baked a cake and could only put two cakes in the pot at a time. I think it takes two minutes to bake a cake, one minute in front and one minute in the back, and at most two pancakes are put in the pot at the same time. How many minutes does it take to bake three cakes? Back in the study, I calculated and came to the conclusion that it takes 3 minutes: first, put the first, second and third cakes into the pot at the same time. 1 min later, take out the first cake, put in the third cake, and turn the second cake over; Bake again 1 min, and let the second cake be baked and taken out. Then put the reverse side of the first cake and turn the third cake upside down, so it will be all done in 3 minutes. I told my mother what I thought, which really saved me a lot of time. Time is life! It turns out that another advantage of learning mathematics is to save time! Deep, too deep!
Mathematics should be studied in life. It is inseparable from life. If you study deeply and thoroughly, you will naturally find that mathematics is actually very useful. Geometry in mathematics is also very interesting, especially the strangest "circle" in geometry. The formula for calculating the area of a circle is S=∏r2. Because the radius is different, the area of the circle is also different. For example, is a circle with a radius of 9 cm equal to a circle with a radius of 5 cm? Let's use the area formula to find the area of two circles, which are 254 respectively. 34 square centimeters and 78.5 square centimeters. The radii of the two circles are different, so the areas of the two circles are also different. If the radius is long, the area is large; If the diameter is short, then the area is small! With this rule, you are guaranteed to do the problem in the future!
Mathematics is like a mountain peak, soaring into the sky. I felt relaxed at first, but the higher I climbed, the steeper the peak became, which made people feel scared. At this time, only those who really love mathematics will have the courage to continue climbing. Therefore, people who stand at the peak of mathematics love mathematics from the heart. Remember, people who stand at the foot of the peak will never see the summit! If you love math, you can learn it well!
The guiding ideology of speech 9 before math class;
The purpose of "listening, speaking, reading and writing" ability training is to learn knowledge well and cultivate ability. But from the current situation, the most neglected is the training of "speaking". On March 2 1 day, Director Zhou Dongqun also suggested this problem in the teaching guidance organized by the Street Education Office. She thinks that speaking at three o'clock before class is short and beneficial. The training time of "three minutes before class" is not long, which generally will not affect the completion of classroom teaching tasks. And every student has to participate, and the students in the class have to train. At the same time, the three-minute speech also satisfied each student's desire to show their psychology to others, provided such an opportunity and platform for students, and promoted mutual learning and competition among students. Therefore, the guidance office decided to start the "three-minute speech before class" activity in the Chinese class of the whole school from the seventh week, and then gradually spread it to all subjects after forming a certain scale and accumulating certain experience. Implementation purpose:
First of all, it trains students' language expression ability. Students express the prepared content within a limited time. The requirements are clear, light, accurate and convincing. Through the speech, the students' inner expressive ability is truly displayed in front of all the students. "Three-minute speech" can help students know more accurately their expressive ability: whether the language is accurate, whether the words are clear, whether the voice is loud, whether the rhythm is appropriate, whether the tone is appropriate, whether the expression is natural, whether the feelings are true and so on. In the speech, students saw others and themselves. While commenting on others, we are also regulating ourselves. Therefore, speaking three minutes before class can organically combine students' "listening, speaking, reading and writing", which can not only improve students' ability to speak boldly, build confidence, but also comprehensively improve students' Chinese literacy.
Secondly, it helps to improve students' writing ability. According to the traditional teaching method, each student writes eight compositions each semester to improve students' writing ability, and the effect is always not obvious. Through the "three minutes before class speech" can effectively make up for this deficiency. Because students want to achieve better results in a three-minute speech, they must sort out the materials before the speech, and then carry out conception, conception, writing and final revision. So the process of saying is also the process of writing. If you want to speak well, you must write well, but you can't cope with it. Only in this way can you arouse students' enthusiasm and stimulate their interest in learning. After a period of training, it is of great benefit to students' writing level.
Third, "three minutes before class" has created a lively platform and opened up a new way for ideological education. The content of students' speeches is rich and colorful, absorbing what they see, hear and feel around them. Such as ideals and aspirations, life values, social life phenomena, personal life feelings, class activities, family relations, reading experience, the relationship between classmates, etc., are of educational significance to students' thoughts and make things smooth and silent. Detailed implementation rules:
1. Before each new Chinese lesson, a student should give a speech at about three o'clock. You can ask those students who are usually bold and active to speak first; You can also do it according to your student number. This arrangement helps students master their own play time and avoid boredom.
2. Adhere to the principle of easy before difficult. Speak from the seat at first, and then speak on the stage; From free speech to propositional speech and impromptu speech; First, you can speak on stage with a manuscript, and finally you can speak without a manuscript. Speak for a minute or two, and then speak for three minutes. The content can be said, heard, seen and felt; It can be a small composition written by yourself; It can also be a beautiful sentence in an extracurricular book; It can even be a natural paragraph that I feel most deeply in the text. Teachers should pay attention to guidance and avoid the practice of letting students look down at the manuscript. As for the form of speech, there are not too many restrictions, leaving room for students to give full play.
3. Encourage more and criticize less. The age characteristics of students determine their psychological characteristics of strong self-esteem and desire for encouragement. Teachers must give priority to encouragement when commenting. Teachers should be good at discovering the bright spots in students' speeches, such as a unique topic, a fascinating beginning, a thought-provoking ending, a wonderful language, a flamboyant action and so on. This will not only inspire the speaker, but also encourage the listener to carry forward these highlights in future speeches.
4. The teacher pays attention to guiding the students to sort out their speeches, and after the speech, guide the students to copy the speeches into small composition books. Make a general evaluation once a week, reward students who speak well and set an example appropriately. After a period of accumulation, the teacher can also instruct the students to bind the speeches into volumes, and then the students will discuss the titles with class characteristics, such as "Collection of English Lecture Notes" and send them to the students.
10 after the implementation of the new curriculum reform, I decided to follow the Chinese "five-minute speech before class" and give a speech for three minutes before math class. The specific method is as follows:
At the beginning, I limited the scope, allowing students to take stories of famous mathematicians, interesting mathematical problems and anecdotes of mathematicians as the content of their speeches, which can be downloaded from the Internet or cut out from newspapers and magazines, and talk about their feelings after the stories are finished.
In this way, after a period of lectures, students' interest in mathematics will become stronger and stronger. On this basis, I will strike while the iron is hot to let students talk about the mathematical phenomena around them, so that students can clearly realize that mathematics is everywhere in life and needs it everywhere. Then, in the column selection, the scope will be expanded to small columns that can explain "knowledge summary of last class", "self-compiled synchronous exercises" and "solving small problems in life with mathematical knowledge", so that students can use their hands and brains, develop creative thinking and enhance mathematical application.
This is different from the homework assigned by the teacher in the past. Students should show great enthusiasm and interest in preparing for this "three minutes before class". Not only is the learning atmosphere of mathematics unprecedented, but students' awareness of applying mathematics is also greatly enhanced. In order to further mobilize the active participation of the whole class, I will draw lots to decide which student will speak in class, and I will also compare them every once in a while. In this way, every student can prepare actively before class. After a period of time, every student will have an "interesting math knowledge book". More importantly, students' enthusiasm for learning mathematics has been greatly improved. "Mathematics" is no longer synonymous with boredom in their eyes, but has become a broad stage for them to explore knowledge and show their talents!
Speech before math class 1 1 Dear teachers and students,
Hello, everyone. Today, I will tell you an interesting math story: both Euler and Mark were born in cities, and they decided to go to the farmhouse with their uncle who grows grapes. They went into their uncle's garden and saw his two sons picking cucumbers in the garden. Mark saw a basket full of cucumbers and asked, "How many cucumbers did you pick?" The naughty little son didn't answer, but clapped his hands and sang children's songs: "Two brothers picked cucumbers, one picked seven or eight, and the other picked eight. How many melons did they each pick? " Euler smiled: "Haha, the children are testing us." He thought for a moment and said, "My brother picked thirty-five and my brother picked forty-three."
Euler and Mark and their uncle came to the back garden. When they saw aunt calling ducks to cages by the river, Euler asked enthusiastically, "How many ducks does aunt keep?"? Let us help you catch them. " Aunt also happily sang: "The sun is setting and the sunset glow is red. I drove the ducks back to the pond. Half stay in the water screaming, half into the cage. The remaining fifteen are with me. How many ducks do I have? " Afraid that Euler would get ahead of him, Mark quickly said, "I know, 15×2×2=60."
In the evening, Euler, Mark and his uncle sat around the grape trellis. Uncle brought a big watermelon, smiled and handed Euler a melon cutter, saying, "If it's unusual, here's a melon cutting problem. Cut three knives into seven melons and eat the remaining eight skins. " Euler said awkwardly, "It's not difficult to cut into seven pieces, but how can you eat eight pieces of skin?" Mark suggested drawing a triangle on the stage, and Euler patted his forehead and said, "I see!" " "Not to be outdone after cutting the melon, Euler said," it's so strange. It is difficult to cut watermelon with a knife. Watermelon is big and round. Cut four knives into nine pieces, and there are ten skins left after eating! "
Euler and Mark spent another happy day, lying in bed, and they sincerely lamented: "There is mathematics everywhere in life!" " "
My story is over, thank you!
Speaking before math class 12 Today is math class. I want to talk about Chinese.
Chinese is the foundation of China's national language, a tool for us to learn written expression, and a weapon for us to know, face and transform the world.
I think of Mr. Lu Xun, who was the standard-bearer of China culture at the beginning of last century. Facing the poor and backward motherland, he was determined to serve the motherland and go to Japan for medical treatment. After returning home, he found that the reason for China's backwardness was not disease, but cultural backwardness. He abandoned medicine and went to literature, published many essays, attacked darkness and backwardness, and awakened the public.
I thought of Mao Zedong. After War of Resistance against Japanese Aggression's victory, I went to Chongqing to negotiate with Jiang. During this period, I published the famous poem "Chun Xue in the Garden", which made Jiang Da angry and gathered many poets to write poems. I tried to win the first place, but I failed miserably. Mao Zedong with passionate words, give directions, won the victory of the China revolution! Here, I want to tell you that I also have a cognitive process in learning Chinese. At first I didn't think it necessary to learn Chinese. Who can't speak Chinese? I began to realize the importance of learning Chinese in my study. In Chinese class, I not only learned writing, reading and analysis, but also learned a lot of truth. I love Chinese class!
Students: Let's learn Chinese well, feel the charm of language, and lay a solid foundation for future growth!
