4. 1、 Cultivate students' interest in calculation
simple calculation is often boring and students are easily bored. Therefore, according to the psychological characteristics of the lower grade students who are active and competitive, we can use a variety of training forms to replace the previous single form of practice. For example: training with games, competitions, etc; Driving trains, rushing to answer questions, breaking through barriers, etc. Various forms of training, not only stimulate students' interest in learning, but also make every student actively participate, so as to get twice the result with half the effort. Senior students can explain the principle of problem-solving more, let students understand the context of problem-solving ideas, know the reasons for this problem-solving, deepen the understanding, will improve interest< Second, pay attention to the training of oral arithmetic
oral calculation is the basis of written calculation, which requires not only accuracy but also speed. The formation of oral arithmetic skills and the improvement of speed can not be achieved by one or two days of training, but by constant training. In my opinion, the effect of mental arithmetic three minutes before class is very good. Before each class, prepare ten oral arithmetic questions for students to rush to answer, or let students write in a small book, check the answers in a unified way, make a summary every other time, and praise and reward the excellent students. The enthusiasm of students has been improved, and at the same time, they will pay attention to the correct rate. Of course, remember some common values, such as 2 π、 three π、 four π……， 112, 122, 132... And so on, which have a very good effect on speeding up the speed and accuracy of oral calculation< Third, strengthen the training of estimation
many problems in daily life don't need very accurate results, so we can use estimation to solve them. In this way, the speed is accelerated, and it does not affect the actual operation. When encountering such problems, let the students estimate as much as possible. In addition, even in the calculation of accurate results, the estimation will also play a monitoring role. Every time we finish a question, we can use the method of estimation to verify its correctness< 4. Pay attention to quick calculation and skillful calculation. Quick calculation and skillful calculation, that is, we usually say simple operation, the correct use of simple methods, on the one hand, can improve the speed of problem solving, on the other hand, can also make problem solving simple, improve students' self-confidence. The teacher can teach some basic laws first, let the students answer the questions, in the example of some calculation problems, let the students find the appropriate simple method. This requires students to have a clear grasp of the basic law of operation, especially the scope of its application. For example, multiplication has distributive law, but division does not. This requires students to divide by a number into its reciprocal, in the use of distribution law for calculation.

7. The title of love ecation makes me think about what love is in this diverse world. With this thinking, I trudged with an Italian primary school student to explore an unknown answer. Love, like air, is always ignored by us because it is invisible every day. In fact, its meaning has been integrated into life, just like parents' love, When we are in trouble and no one supports us, it is our parents who are still with us. At night, we don't forget to tell them to go to bed early, I realize that parents all over the world have a deep love for their children. Amrico has a diary that they read and write with their parents, but now many students still have a small lock on their diary. The simplest things are most easily overlooked, just like the deep love between parents and children in this great love, which many people can't feel. If love is a travel, some people may have objections. But love has no end, Happy travel. Just like life, if we regard life as a sentence, people will do heavy work for the sake of one day's release and detachment; On the contrary, if you look at life as a tour, you will feel relaxed and enrich yourself with new things every day. Therefore, you want to go on, even put in enthusiasm, and don't care how long it will last. At this time, this feeling has been sublimated into a kind of love, a kind of love for life, I went into the life of amrico, I went into the life of amrico, and I saw how they learned, lived and loved. In the moving, I found that love contains the pursuit of life. If love is a galloping blood and a jumping heart, then I think it is a noble love for the country; Slogan & quot;, But as a person with conscience, this kind of love should be firmly embedded in our hearts. When I read the moving scenes of Italian people blowing up their legs for their country and defending their homeland, I can't help thinking that our motherland was also soaked with the blood of the Chinese people, Love is great because it is not only for indivials, but also for the dignity and emotion of the whole nation. In the ecation of love, love is compared to many things, which is true and not only these; What is love; There won't be a definite answer, but I have completed my thinking about love - love is great, infinite, great power. Doing housework for my mother this summer, the teacher left a special assignment --- to experience my parents' working life. I'm talking about summer vacation, so I can't let myself be idle. Slowly, used to do some housework, for mom and dad to share. I told my mother about my homework, and my mother also said that your teacher's idea is very good! I'll set up a job for you! And do not only once, you are teachers, a stay on the serious homework, usually do not do. You're going to give me a summer vacation this time. The first is to mop the floor. Just mop it twice. My mother didn't think this job had much weight, so I got an extra job - washing dishes. I will show my hands in the kitchen, and I will take the initiative to wash my parents' feet. I like washing dishes best. Just out of the pot of food on the plate is delicious, and we finished eating, leftovers piled up in the pool, is the resie. The next day when washing dishes, it may be not adapt to it, leftovers taste particularly bad. For this reason, I wear plastic gloves to wash the dishes, and the dishes are full of oil stains. There are also some leftovers lying lazily on the plate and thrown into the garbage can, which makes people cover their nose. I'm just looking forward to it. Wash it quickly. It looks clean on the surface. With such a reluctant mood, I washed the water once or twice. Slowly, I accepted the smell and didn't feel bad. I don't need gloves when I wash the dishes. I'm just imagining that I'm going to bathe the bowls and plates, remove the stains from them, and put on a brand new and clean look. My hands itch when I see my mother cooking. I said to my mother, "let me help you cook today." Then he rolled up his sleeve and washed his hands. I first pour the rice into a small bowl, then pour it into the pot, twist the water tap, connect a small half, and start to wash the rice by hand. After washing the rice three times like this, I pour the water, and then put the rice on the fire to make the water less than one centimeter. At this time, I began to cook. What do I do? By the way, make fish flavored shredded pork! My mother helped me prepare the carrots and asparagus, and also helped me find a small knife. I began to cut the carrots. First, I cut them into pieces, and then cut the carrots into two pieces. The same is true for asparagus and shredded meat. But the shredded meat is a little difficult to cut. When it's all ready, it's time to do it, Pour a little oil, then put the sauce in, stir fry twice, and then put the shredded meat in, stir fry twice, accidentally, my hand touched the pot, I immediately cried with pain, my mother quickly took the shovel, let me use cold water to wash my hands, I thought: cooking this thing looks very common, it is not easy to do it! This reminds me of one thing that happened last week... Last Sunday, our family had dinner early. My mother, who had been tired all day, began to wash the dishes according to the original plan. So I made up my mind to realize this wish today. Just when my mother was still washing her teeth, I had prepared a basin of hot water full of love for her early. I quietly went to her mother and said happily, "Mom, let me wash your feet today and do my filial ty.". Mother felt very confused after listening, said: "daughter, how did you suddenly grow up today and learn to be filial to your parents.". I said: "Mom, this is the result of Teacher Ecation in school. You helped me to do a lot of things before. Today it's my turn to repay you.". After listening to her mother, she said with a smile: "daughter, if you have this filial piety, your mother will be satisfied. You'd better try to do well in your study. That's the best reward for your mother.". I said, "no, I have to wash your feet myself today.". My mother saw that I was very tough and had to comply. I put down the basin, put my hand into the water, measure the temperature of the water to see if it is suitable for washing feet, feel a little hot, I added some cold water. Then help her take off her socks and start to work. From the front of her feet to the back of her feet, from the back of her feet to the soles of her feet, I gently rubbed her feet and found that there was a thick cocoon on the soles of her feet. I knew that she worked too hard for me, and I admired my mother more. After a while, I washed her feet clean, mother smile, "this is the first time I met this kind of happiness.". I immediately replied, "Mom, when I grow up, I will do more for you." In this holiday, I did a lot of housework, which proved that I grew up and learned to do housework. Although I have been exhausted, but can do housework for my mother, my heart is still sweet. O(∩_ ∩) O ha ha ~ come on! Books are the treasure house of knowledge. It makes the accumulation and development of human knowledge and culture, and makes the ignorant become erudite; It is it that constantly enriches my mind and brings infinite joy and hope to my life. When I didn't even know a word, I had an indissoluble bond with the book. When I was very young, like other children, I liked to hear my mother telling stories for me with storybooks. Unlike others, I always listen to every story three or four times before I give up. In the kindergarten, the teacher accidentally found that I could tell stories, so he took out a story book for me to read to the children. Just when the teacher was surprised that I could know so many words, she suddenly found that I had taken the book upside down and was staring at it. It turns out that these stories have been "heard" and "recited" since I was a child. With the increase of word recognition, I can finally read by myself. What a happy thing it is! Every time I was alone in a room, with delicious food, I was intoxicated with excellent works, and lost myself in the pages. That kind of happiness was incomparable to any other feeling at that time&# 57348; I'm intoxicated with literature. From 365 nights to Andersen's fairy tales, so many moving stories and kind-hearted images together shape my simple and optimistic character. From red rock to how steel is tempered, I graally realize the meaning of life and find the end result of my soul in those thousand times of indomitable struggle and countless iron soldiers“ The experience of "San Mao" makes me feel more happy in my life, and the allusion of "head hanging beam, cone stabbing stock" always urges me forward&# 57348; Graally, my interest turned to science books. From the first set of Knowledge Series "one hundred thousand whys" I came into contact with, I don't know how many mysteries I have solved and how many fresh knowledge I have learned. The next reading of "network book", "interesting physics" and so on, I can't help but put down my mind and forget to eat and sleep. It should be said that I would never have been so interested in natural science today if I hadn't read eagerly year after year and day after day&# 57348; Books are my closest friends. They give me knowledge and strength. Today, I roam in the sea of books and learning, tomorrow, I will use knowledge to create life. All this, how can we not say that it is the gift of the book - this is the accident between me and the book. Book, what a simple and ordinary eye! However, it occupies a very high position in my mind. In the long river of my memory, there are always "the story of books" in my mind. I have an indissoluble bond with books. Whenever I hold up a book with a book cover, I can't help thinking of the past... How important books are to me! If I believe that life is the first, then books must be second only to life one - ranking second. I used to cry for the book, sad for the book, that may be my attachment to the book. Whenever I look at a book "retirement", I feel extremely sad, it's like digging half of my flesh. I carefully hide the book in the bookcase, I can't bear to dig out my own flesh? From the first time I saw her, there was an inexplicable feeling in my heart: "she was predestined with me." In the days after that, I would try my best to get close to her and try to understand her. After a short time, I graally found that I had fallen in love with her deeply. Perhaps tired of the bitter and tasteless ABC, or to escape the suffocating x + y = 4, I asked her out again and again, from her fragrant title page, to a strange and fresh world. Don't be "there's gold in the book"
