In a village, there is a path leading to the distance. There is a big tree beside the path, and there is a fence beside the big tree. There is a rape flower in the fence. Xiaomei and Xiaoming are playing. Suddenly, a golden butterfly flew in. Xiaomei and Xiaoming saw this yellow butterfly and thought: This butterfly is really beautiful. How nice it would be to take it home and play in a cage! Thinking about it, I started catching butterflies. Butterflies fly east and west, but I can't catch them. At this time, the butterfly flew into the cauliflower and could not be found any more. Xiaomei thought for a moment and said, "The butterfly can't be found when it flies into the cauliflower, because the butterfly is yellow and the rape flower is yellow, so the butterfly disappears when it flies into the cauliflower."
2. It takes about 500 words to write an imaginary composition with arbitrary graphics. Don't reward 30 points too much. In class today, the teacher drew a circle on the blackboard. Let's imagine something and think about it. I suddenly thought of a circled pattern: a duckling with a round head.
In this semester, I have a little duck. It has a round head, big black eyes and a flat mouth. It looks smart. Its hair is golden yellow and furry, and it feels very comfortable.
It has strange feet and webbed feet, which can help it swim in the water. This duckling never seems to feel tired, and always chirps, especially when no one is with him.
I'm tired of listening, so I have to stay with him for a while. Really smart! He also likes to go out for a walk. As long as I take him out, he shouts happily and rushes out the door, but he dare not stay too far away from me outside, and honestly follows me closely, giving me a feeling of caring about him. Ducklings can eat well. They can eat anything that is fed to them.
Once it helped me a lot and ate my leftovers. I praised it as "save the little expert!" "But because of my little negligence, the duckling died unfortunately, so I was very sad and cried for a long time!" Students, shall we talk about it? "The teacher's words suddenly pulled me back to the classroom.
I decided to write my favorite duckling as a souvenir! After this class, I found that our children's imagination is very rich, but it is rarely applied to real life. We should try our best to realize what we imagine. At the same time, I also understand that we should cherish life and protect animals and plants. Only when we live in harmony can the earth become a beautiful green world.
Write a composition with any three numbers. I added a few strokes to the triangle and it became a kite.
I want to send it to the blue sky and let it fly freely. I added a few strokes to the triangle, and the triangle became a small fish.
I want to send it back to the sea and let it swim in the ocean. I added a few strokes to the triangle, and it became the Olympic torch.
I want to give it to the Olympic Games and let the torchbearers pass it one by one. I added a few strokes to the triangle, and the triangle became a purse.
I gave it to my mother so that she could use it at work every day. I added a few strokes to the triangle and it became a new house.
I'm going to give it to the children in the mountains and let them live in a new house. I added a few strokes to the triangle and it became a Christmas hat.
I wear a Christmas hat and give candy to my teacher. Triangle really changes a lot.
4. "Creative Tangram" composition 450-word Tangram/kloc-One of the most popular puzzles in the 9th century is Tangram.
The popularity of Tangram is probably due to its simple structure, simple operation and easy understanding. You can use jigsaw puzzles to spell out your own designs at will, but if you want to use jigsaw puzzles to spell out specific patterns, you will encounter real challenges.
This is the fun of jigsaw puzzles. The jigsaw puzzle has a simple structure, which easily leads people to think that it is easy to solve its problems, but this idea is one-sided.
/kloc-more than 0/600 patterns can be put together by puzzles, some are easy to spell, some are quite mysterious, and some are specious and full of contradictions. Tangram is an invention of working people in ancient China.
Invented in the early Ming Dynasty, it was widely circulated among the people in the Ming and Qing Dynasties. Lu Qing Yi Tian wrote in Volume I of Leng Lu Miscellaneous Knowledge that "there are seven close-up pictures with seven numbers in five forms, and there are thousands of variations. The body is small and changeable, and the tools of the game are enough to dispel boredom and break the silence, so secular people like it. "
I don't know when, the "seven clever pictures" spread abroad and were welcomed and valued by them. Needham said it was "one of the oldest pastimes in the East", and the library of Cambridge University in England still has a "Seven Clever New Books". American writer Edgar Allan Porter refined a puzzle with ivory.
Napoleon amused himself with jigsaw puzzles in exile. Who would have thought that Tangram would compete with Napoléon Bonaparte, Adam, Du Lei, Edgar Allan Poe and Carol? In fact, they are all fans of jigsaw puzzle.
There are many original sayings about the name of Tangram: 1. It comes from the abandoned English word "trangram": a strange-shaped gadget; 2. From the Tang Dynasty (China Tang Dynasty) with the suffix-gram (Greek meaning works); 3. It comes from the term "tanka", which means people on a coastal ship. In addition to providing food and washing clothes, they also provide some entertainment during the transportation ferry.
There is a China puzzle made up of seven boards. The word Tangram evolved from tanka game (the game of others on board).
All these statements seem to have some truth. Probably the original Tangram's strong interest and its entertaining explanation inspired the literary creativity of Sam Lloyd, a famous American puzzle solver.
1903, 6 1 year old, he wrote in the eighth tea cover book: "According to the introduction of the encyclopedia, the origin of jigsaw puzzles is extremely old. In China, as an entertainment object, its history can be traced back to 4,000 years ago ... "The development process of China first evolved into the figure of butterfly wings from the Song Dynasty, and then evolved into a modern jigsaw puzzle from the early Qing Dynasty.
Yan Ji Tu-Tangram's original face is "Yan Ji Tu", which means to entertain guests. Huang, a scholar in the Northern Song Dynasty, initiated this idea. He first designed six rectangular tables, which can be adjusted according to the number of guests at the banquet, and then added a small table. When all seven tables are put together, they will become a big rectangle, and the combination can be changed endlessly. It's almost like a modern jigsaw puzzle.
Butterfly Wings-Later, according to the principle of "swallowing several figures", Geshan in Ming Dynasty designed "Butterfly Wings", which were composed of thirteen different triangular figures, which together were the shape of a butterfly's wings, and after being separated, more than 100 figures could be spelled out. Tangram-Modern Tangram was developed on the basis of Yan Ji Tu and Die Ji.
Benefits and Uses Tangram has numerous benefits and uses. The following are the benefits and uses of Tangram: shape concept, visual discrimination, intellectual skills, visual memory, hand-eye coordination, encouraging openness, spreading thinking and creating opportunities. Tangram is a good partner to inspire children's intelligence, both ancient and modern.
It can connect children with objects and forms, and has great development space for cultivating children's observation, imagination, morphological analysis and creative logic. Now it is widely used by parents to help children learn basic logical relations and mathematical concepts.
It can help children understand the meaning of various geometric figures, numbers, perimeters and areas, and understand Pythagorean theorem. Tangram can also teach children to recognize colors and guide them to understand the division and synthesis of graphics, thus enhancing their hand intelligence, patience and observation.
It can also be used to tell stories, connecting dozens of puzzle pictures into a series of connected pictures, which can be told to children like cartoons. Spell out a few cats, a few dogs and a house first, and you can tell a wonderful and touching story.
5. Regarding the composition with graphics as the main topic, I bought a ticket when I arrived at Changzhou Dinosaur Park. After buying the ticket, my mother said to me, "have you seen the peas?" It's too big here. It looks like many figures. You should observe them carefully and say what you see. " Just before math class, we learned triangles, quadrilaterals and so on. I thought my mother was trying to test me, so I didn't feel embarrassed when my mother said that. I didn't hesitate to tell my mother that it was no problem. As soon as I got to the gate, I saw a car beside me. I looked at it and said that the doors, windows and seats are all rectangular, and there is a canteen in it that is square. Further down, there is a big dinosaur. I think its body is oval, its neck is cylindrical, its tail is like a Yangtze River Delta, and its legs are like four big cylinders. I happily took a picture with the dinosaur.
When we went to the maze, I saw many dinosaur fossils in it. And some oval dinosaur eggs. Now science is really developed. Those electronic dinosaurs will walk back and forth and roar from time to time. In that environment, you feel as if you have really returned to the dinosaur era. Through a long rectangular tunnel, we also played high-altitude surfing and rushed down from the height of 18 meters. The shape should look like a Yangtze River Delta. Although we were all wearing ponchos, we were still wet by the rain. I also saw some figures in the dinosaur park, including trapezoid, parallelogram, right triangle, isosceles triangle and so on. I had a great time today. I not only visited the dinosaur park, but also saw so many people. My mother told me that there are many things in life that we learn from numbers. As long as you observe carefully, you will find the mystery. It turns out that the graphics in mathematics are so interesting!
6. How to write an interesting graphic composition Today, we learned how to assemble plane graphics. The teacher arranged for us to combine various patterns with school tools. I am very happy. First, use the school tools as the head, △ as the neck, □ as the body, and then two sticks as the feet. A lovely little man appeared in front of my eyes. I watched it and suddenly had a good idea: why not make him a sugar-coated gourd? So I made hawthorn with three "○" s, and then made a stick with a small stick, so a string of bright and attractive candied haws was given to the lovely little people.
In the afternoon, Teacher Chen showed many children's works, including trains, small houses and so on. Of course, my Sugar-Coated Berry is also on display in the Learning Park. Children, do you think graphic puzzles in mathematics are interesting?
