I think there is a way to learn math. As long as you master this policy of the Party and apply it, I believe that mathematics will become your friend. The most important thing in learning mathematics is to be good at thinking.
If you compare mathematics to a lock, then thinking is a golden key to open the lock of mathematics for you. For example, some students listen carefully in class and can swallow all the contents of the teacher's speech, but they don't digest or absorb it, and eventually they are "malnourished".
Mastered because he didn't develop a good thinking result, he couldn't reprocess what the teacher taught, he couldn't sort it out, and he didn't know the ins and outs of the road. Of course, he can't grasp the true face of knowledge. We should learn the working methods of bees. Bees can not only collect honey, but also make honey.
In this respect, some students do better. They not only listen attentively in class, but also think about the reason of such a solution when the teacher talks about the solution of a certain problem, although the solution of this kind of problem will be introduced later. In this way, the teacher is integrated.
While studying mathematics, we should pay attention to cultivating our good thinking habits, learn to use them flexibly, and draw inferences from others to get twice the result with half the effort. Some people say, "Mathematics is profound and unpredictable, which makes people puzzled and unpredictable." .
But in my eyes, mathematics is at most a set of knotted ropes. You must untie one knot after another patiently, and one day you can untie all the knots. Mathematics is the use of learned knowledge to solve unknown problems.
Learning mathematics requires perseverance, patience and perseverance. Just like a person who digs a well, he digs deep and gives up when he is close to the water source; All the previous work will be in vain and fall short.
It is also important to be careful when solving math problems. As long as there is a little negligence in calculation, the whole problem may go wrong.
Just like playing chess, you may lose everything if you make a wrong move. Don't wait until you have done something wrong to regret it. No regret medicine in the world comes from one action.
Bacon once said: "When you see Wang Yang, you think that people who have no mainland are just poor explorers", and "poor explorers" are doomed to fail, and the fundamental reason for their failure is that they have no spirit of exploration. Scientific invention needs exploration spirit, and mathematics also needs exploration spirit.
Don't always think that there is only one solution to every problem, "All roads lead to Rome", but try to explore, think and discover. Self-confidence is also the key to learning mathematics.
Don't always think that what the teacher says in the textbook must be right. You should have your own opinions and don't listen to other people's suggestions. Everyone should have confidence in themselves. One can't be successful forever. In the face of failure, a person should have confidence in himself and believe that he can do it.
As Goldsmith said, "The greatest glory in life lies not in never failing, but in rising again and again." As the saying goes, "Nothing is difficult in the world".
Han Yu, a writer in the Tang Dynasty, said, "Industry is good at diligence". Academic attainments come from diligence.
Just like these reasons, learning mathematics must be previewed first, so that classes can be much easier. When the teacher is lecturing, he should preview the questions that he doesn't understand carefully, review them regularly after class, then finish his homework after class, and do more exercises in his spare time to better consolidate what he has learned.
I study mathematics. In addition to the usual preview, I will read the math textbook from beginning to end before the start of school, grasp some knowledge and get a general understanding of some contents of the math textbook. Know what is simple and what is complex.
Whenever the teacher finishes each class, I will carefully read the content of the class and dig out something from it. At this time, my reading experience.
Listen carefully and finish your homework independently. I will also squeeze out some spare time to do some related exercises to better understand, master and consolidate what I have learned.
Although learning is very tiring now, if we can aim at our ideals and take learning as fun, then we can turn tiredness into fun and learn mathematics happily. If we don't suffer now, it will be more painful in the future. If you eat more bitterness now, you can avoid a lot of bitterness in the future, so you should eat more bitterness now.
The biggest enemy of learning mathematics is carelessness. Some people are just so-so, but if you talk about him, he will say "why take things too seriously".
Yes, why take things too seriously? It seems that it doesn't matter much not to take them seriously now. What will this society look like if it is not serious? When the teacher is giving a lecture, the students can't understand. The students' homework is so poor that the teacher can't understand it; The traffic police yawned at work and the accidents continued; The factory director relaxed the management of the enterprise and suffered losses year after year.
What's more, if the satellite launch orbit is miscalculated by a decimal point, I'm afraid there is still a huge sum behind the fiscal deficit. All these show that we should be meticulous and not careless.
The same is true of learning mathematics. As long as you think you have learned something, your pride will rise. If you don't sort out what you have learned, such as formulas and definitions in mathematics, it will be easy to get confused, which will make you have some problems in doing the problem, and even confuse the problem. This learning method is impossible. Only by working hard and studying hard can we get good grades.
Great people are great people, not mediocre people. We should study hard, do things seriously, form good study habits, do things well and achieve something.
2. Write a composition that I like math. In my opinion, 300 words of mathematics is a very interesting subject. Some people say that it's sad to see math, and they don't like it the most. I don't understand. The key point is the attitude of two words.
Yes, that's the attitude towards mathematics. I can see someone smiling with satisfaction after solving a math problem. I can also see that some people ignore the problem after seeing it, which is also a problem. The attitude of giving is really different. The reason why you don't like math is that you can't put the right attitude on math. I like math because it can exercise my thinking ability and logical way.
So my brain won't stagnate. I like the process of doing math problems. When you solve a math problem, the result is more perfect. So, students, please correct your attitude. I believe that from this attitude, you will be full of infinite mathematics.
After all, it is pure hand.
3. Composition I like math. I like math. Do you know why I like math? Because of the charm of mathematics, it attracted me deeply.
I learned a new knowledge today, which is a simple addition and subtraction algorithm. After learning the simple addition and subtraction algorithm, my calculation speed is much faster and it is easier to learn to calculate.
Give an example! For example: 367 498=? I just have to think like this: add up 498 to make 500, and then use 367 500. I found that I added 2, so I subtracted 2 from the total to get 865. And what about 796 295? I think so: 796 can be counted as 800 plus, and 295 can be counted as 300. One adds 4 and the other adds 5, so the formula becomes 800 300-4-5= 109 1. Look, how convenient it is! After learning the simple algorithm of addition, learning the simple algorithm of subtraction will be much easier.
Such as: 483-299, hehe, you can find the way by gently moving your head. I'll take 299 and subtract it from 300, because it's 1, so just add 1 to the result, which is 483-300 1= 184, and the calculation is much simpler.
However, I can warn you: it's best not to think about the minuend when doing subtraction, or you'll be in trouble! Now, I like math more and more, because it makes me learn to calculate the results quickly, and math really makes me remember deeply.
4. Write a composition with "My favorite math", thank you. Other subjects are also "my favorite math".
Today, Teacher Yuan talks about how to find the least common multiple. The teacher said, "If two books are prime numbers, their product is their least common multiple." I think: the number smaller than their product may also be their common multiple!
After class, I calculated several pairs of prime numbers with my exercise book, but their least common multiple is equal to their product. It's amazing! The truth of mathematics is amazing! I will study hard and master more skills.
My discovery
Students, have you made some casual discoveries in math study like me? Now I will introduce some of my findings.
If you want to calculate a multi-digit multiplied by 5, do you want to calculate it vertically? But I can do it with my mouth, because I found a little trick. Do you want to know? Let me tell you: calculate the product of 48532*5, first find this number 485320, and then divide it by 2. Can I take it orally? 242660 This is the product of 48532*5. Do you know why? I first expanded the original number by 10 times, and then reduced it by 2 times. Is it equivalent to expanding five times? Have you mastered this little trick?
I also found the same thing: multiplying a number by 1.5 only needs to add half to itself. (think about why? How about a number multiplied by 15? Use the method just now to add one more step-you have already thought of it, and then expand it by 10 times!
I also found a multi-digit, and the last two digits meet this requirement: ten digits are odd, and one digit is 5. Multiplied by 5, the last two digits of the product must be 75. I think why is this? Because the unit of multiple digits is multiplied by 5 to get 25, the unit of product is 5, which is the tenth power of 2, and the odd number of ten is multiplied by 5 to get 15. This 5 must be added with the 5 to be written on the ten, so the product must be the tenth power of 7 and the tenth power of 5. In the same way, it is not difficult for you to deduce that a multi-digit number is even in ten digits and 5 in one digit. It is multiplied by 5, and the last two digits of the product must be 25.
Can this discovery be explained by an ingenious algorithm of multiplying numbers by 5 that I mentioned earlier? Think about it, they are the same, because after this number is expanded by 10 times, the last two digits are 50, and then divided by 2, there may be a remainder of 1 in the hundreds, and when combined with 50, 150÷2=75 is the last two digits, or there may be no/kloc-0 in the hundreds.
Students, is my little discovery insignificant? But I am very proud, this is the result of my own observation and thinking. Aren't great discoveries made up of these bits and pieces? Students, let's be a diligent thinker and discoverer!
5. I love math composition 360 words I love math composition 360 words If I want to say what I like to do best, I will definitely answer: I love counting, because I am always happy after I get the correct answer every time. I listen carefully in every math class because I can learn a lot from it.
I can know the length, width and height, and find out the area of the graph. I can also make a cube or cuboid out of cardboard and enjoy it every time. Of course, I can also learn how to get the result of a question. If I know the unit price and quantity, I can calculate the total price of the goods, which can help me a lot, because my mother sells apples in the vegetable market, and I will help my mother every time. After the customers buy apples, I will calculate the money quickly. My mother always praises me and rewards me with a delicious candy.
Mathematics brings me happiness and constantly tests my intelligence. I love arithmetic, and I love math more. I dream of becoming a great mathematician when I grow up, so that I can teach better little mathematicians.
6. My favorite math teacher's composition My favorite teacher wears glasses with red borders and has short hair.
You know who she is. She is Miss Zhao, the math teacher and head teacher we are all familiar with. She has a pair of magic glasses with a red border. One day in math class, the teacher suddenly turned around and his glasses disappeared.
The teacher said, "See what changes I have?" The student said loudly, "The glasses are gone." The teacher turned her glasses again and came back.
The students said in surprise, "Teacher, your glasses are amazing." The teacher smiled, and so did we.
What impressed me the most was that in a math class, I cut a unit and cut a picture of a villain holding hands. The teacher carefully cut the villain on the podium, and the students watched it carefully below, but it was really not easy to do it. The teacher drew a cut step on the blackboard. At the beginning of the students, the teacher checked them one by one and found that they could not be cut. The teacher always explains patiently until we all cut it.
There are many such stories. I believe you will like my math teacher after reading my composition.
