Ms. Li Jing told us to stand next to the long table and observe her rolling out the dough. Ms. Li Jing rolled out the dough very quickly! She grabbed a small piece of dough and gently pressed it down with her left hand, turning it into a small round cake. Then she worked with her left hand and right hand at the same time, holding the edge of the cake with her left hand and turning it, while her right hand held the rolling pin and kept crushing the cake. In the blink of an eye, a piece of dumpling skin was lying on the panel. Tsk, tsk, that's great craftsmanship! I watched with envy, so I also picked up the rolling pin and rolled out the dough like that. Within a few seconds, the dough stuck to the rolling pin like a piece of plaster, and when I tried to remove it with my hands, the dough cracked. Looking at the "injured" crust, I was at a loss for words, but the teacher next to me, Ms. Li Hong, patiently taught me how to solve the problem. With the help of the teacher, I successfully rolled out a piece of dough without any damage. I was so happy to see my own work!
Next, I began to listen to the teacher teaching dumplings. He saw the teacher's hand upward, and then a spoon scooped up a spoonful of dumpling filling in the center of the dumpling skin, and then the dumpling folded a little bit, with both hands of the thumb and forefinger skillfully pinched, a chubby dumplings presented in front of us. I followed Mr. He's example and scooped up a spoonful of dumpling filling and put it on the dumpling skin. What's wrong? Why can't I wrap it? Mr. Wang looked at me and said, "You put too much meat into the dumpling." After I heard that, I put less filling. After a while, a "medium-sized" dumpling was lying in the palm of my hand.

"A fox." Everyone answered in unison.
"I say it's a leprechaun." The teacher said. We all opened our eyes wide in surprise at the teacher's words.
The teacher went on to say, "In the countryside, there is often this phenomenon, some people are sick, not to the hospital for treatment, but they go to the witch, the witch lied to him that there is a demon attached to him, and so, they make some false signs of exorcism, and burn incense and kowtow, and ask for blessings from the gods. Are there really demons in the world?" Some of the students shook their heads, and some were half-hearted.
The teacher added: "Do not believe, please look at the students on this piece of paper is a fox spirit." We laughed and laughed, the painting is clearly a fox, how to say it is a leprechaun? It's funny!
The teacher, however, said in a serious manner, "Well, now I kill the demon to show you!" Just see the teacher from the basin full of water, took out a kitchen knife, toward the fox's neck cut. All of a sudden, the fox's body was literally "bleeding".
"Class, do you know why this happened?" the teacher asked. The teacher asked. "It's probably because the fox's color recedes." "And?" The classroom was silent, and everyone cringed.
"Let me tell you." The teacher explained, "My tub of water was not a tub of ordinary water, but a tub of lye. I sprinkled some more phenolphthalein on the fox beforehand, and the combination of alkaline water and phenolphthalein will turn red, which is called a chemical reaction, and you will learn about this when you go to middle school." After hearing these words, the students came to a realization.
Finally, the teacher also told everyone that: "In nature, there are many phenomena that people can not explain at present. So some people with ulterior motives, make up what ghosts ah, demon ah to scare people. Witches take advantage of people's weaknesses to deceive those who do not understand science. Therefore, we should study hard to learn scientific and cultural knowledge, believe in science, and eliminate superstition."

This afternoon, the teacher gave us an interesting class team class. The game is one, two, three wooden man, the rules are waiting for the teacher to turn his head can not move or laugh, who moved or laughed counted as a loss, who first touched the teacher's back counted as a win. The teacher divided us into two teams, a team called vowed not to laugh team, the other team called praise laugh in the heart, to stop laughing in the face.
The game began. After the teacher said "start", some of the students walked forward a few steps, some still stay in place, some lying on the table, some sitting on the chair ...... we are like cheetahs waiting for the opportunity to touch the teacher's back. When the teacher saw that we neither moved nor laughed, she thought of a brilliant plan. Then she kept telling jokes and making "ha-ha" noises. After a few minutes of laughing, someone from the team that vowed not to laugh finally couldn't hold back and laughed along with us. So, the team lost because the student didn't have enough stamina.
My favorite part of the game was the third game, because the teacher sent the players who were eliminated in the first two games to make us laugh. They made a "haha" sound of laughter in the ears of others, and blew air in front of the face of others ...... the situation, as if they were playing a monkey. However, the team being played are very strong-willed, very tacit understanding to take the distraction approach to hold back the laughter. In the end, until the bell rang they did not succeed in teasing a person, had to return to their seats resentfully. At the same time, the classroom also broke out a burst of earth-shattering laughter, waiting for so long, we can finally laugh.
Ah! What a funny class! I hope the teacher can draw a lesson every week to let us play, because this will not only let us grow insights, but also relieve the pressure of learning, which makes us more like going to school.
An Interesting Lesson Essay 500 Words 10Today, as soon as I walked into the classroom, there was a burst of music. The melody of that music was so nice, and the lyrics were so familiar. Fascinated us to move and concentrate on listening. We listened so attentively that even Xiaogang, the "king of naughty ghosts" in our class, quieted down. Later, we listened carefully and realized that the teacher was playing "The Descendants of the Dragon". Accompanied by the song, the teacher told us that today we have to swim in the paradise of the dragon, to understand the dragon, feel the dragon, feel the endless charm of traditional Chinese culture!
The game began. The first round is even a company, the teacher let each group choose a representative of the "battle".

Started, the teacher let me go on stage even afterword, I put "Dragon Gate Formation lack of people - can not swing up" connected to the "spirit". I said, "I'm not convinced," I said. The teacher said, "If you're not convinced, you'll have to try harder next time!" In the end, I was wrong two, Xiaohong also wrong two, we tied.

", everyone was talking and competing to be the first to say it. The classroom was thrown into chaos. "Quiet!" The teacher's "long whistle" finally made the classroom quiet. The final evaluation of our group won.
The game continues, and the excitement continues. In the game, there are like dancing like the performance of the "tornado"; there are like a desperate man like back and forth performance of the "dragon boat"; there are also like a silly goose like nothing to perform. The performance has brought us a burst of laughter.
This class is really interesting. Not only let us feel happy, but also let us learn a lot about the knowledge of the dragon, let us be proud of themselves as the descendants of the dragon. I love the myth of the mighty dragon. More love our Chinese people **** and country.
An Interesting Lesson Essay 500 Words 11As a real Tongxiang person, I can't speak the local dialect, which makes me a little ashamed.
A few days ago, my mom took me to a community dialect class.
At the beginning, the teacher started with a familiar song called "Family Song", which we all sang along with (in Mandarin). Then, the teacher showed us a table with dialect versions of family members' names, and she pointed to the board and said, "Look, children, this is a character relationship table. A boy raised his hand high and said slowly and red-faced, "Grandma is 'Niang Niang', sister is 'Ah Da', and grandpa is 'Satay' ......" "Well said." The teacher praised, "These are relatively simple, it's not difficult to defeat you, next let's learn a few harder ones." The teacher smiled and pointed to the words "端蛋汤" and said, "'Get egg hot.' Xu Zhixin, you recite it." Because I was afraid that my odd pronunciation would draw laughter, I gently squeezed out the phrase "得蛋烫". As expected, it made a few of the students next to me laugh.
The teacher said, "Don't laugh. Mandarin can make you go far, but dialect can teach you not to forget where you started from; Mandarin makes you communicate smoothly, and dialect can make you feel infinite warmth."
The teacher also called several students, everyone's pronunciation is not very standard, learn a word, the classroom "boiling" once. The teacher also smiled and said: "It seems that there are still many students will not say, we come back to read along, play - white phase, time - Tatsumi ...... "We are very engaged in learning, like opening a new door!
Following the dialect, the teacher took us back to our childhood and revisited the game of "Catch the Week".
Back home, I shouted at my dad, "I want to go to the White House tomorrow!" Dad was surprised, busy asking me where I learned. "Hey, hey, can't imagine, today I participated in the dialect activity, of course, the teacher taught me!" I smiled proudly.
Dialect records the local customs of a place and depicts the rituals and culture of each place. I felt the fun of it, and I will try to use dialects in my future life.
An Interesting Lesson Essay 500 Words 12Today I had a very interesting lesson.
The teacher taught us a lot of new knowledge in the class, which gave me a new understanding of the language. In the past, in the language class, the teacher would only talk about the paragraph of the text, the meaning of words and phrases, I always thought that the language is just so little, just copy and memorize, but after Mr. Le's class, I changed my mind - it turns out that the language can have so much to learn.
During the class, Mr. Le talked about a lot of new knowledge: such as the central idea of the article is created to make people understand the truth of being a human being; read aloud the composition with feeling, you can taste the composition more y, so that the composition is easier to understand; the techniques in the reading of the exam can be accumulated as much as the usual reading; writing is not to have talent, but rather, to have feelings, to be able to feel.
In the class I also know a lot of truth, Mr. Le said well: "Learning language is learning to be a person." We have to learn to use different attitudes to the mood, life labeling, that is how to produce a hundred and eight generals. We have to learn to feel life, and that's how we produce sense. We have to become giants of thought, that's how we produce mindfulness. Being human is a good teacher and a good friend, and being human has a close relationship with language.
In this class I got to know the 108 generals for the first time. They are divided into two kinds of emotion and reason. They have many names: such as Life, Beauty, Happiness, Health, Tolerance, Respect, Mindfulness, Habit ...... Each card is a story, each card represents an emotion, they pull us how to write essays, they pull us how to feel. Grandpa Barkin said well: "I write not because I have talent, but because I have feelings ......" Only by using feelings correctly will we go further and further down the road of composition.
This interesting class, let me re-know the language, it let me know that only "feeling" will lead you to the right way in literature.

Since school, interesting and lively lessons we have heard many times, but the most memorable to me to count a math class.
That day, the math teacher, Mr. Liang, walked into the classroom with a lesson plan in his hand, and the chattering in the classroom stopped immediately. Mr. Liang said to us, "Students, today we are here to learn Unit 5 - Tree Planting Problems, please turn your books to page 73." Everyone took out their math books at once, and the sound of "brushing" could be heard in the classroom. The teacher said, "Now please do the math for the first problem." Within a moment, the duty student Liu Xiurui raised his hand, the teacher said: "Liu Xiurui, you say, a 600-meter-long road, every 15 meters to plant a tree, both ends, how many trees can be planted?" Liu Xiurui answered, "You can plant 40 trees." Mr. Liang said aloud, "Please all draw a picture on the paper." After a while, Liu Zhenglin spoke, "Mr. Liang, no, it should be 41 trees." Mr. Liang smiled and said, "That's right, today we are going to talk about the 'one cut plus one' principle. Now, please discuss in groups to see if you can come up with other solutions to tree planting problems."
After a heated discussion, our group sorted out three ideas: 1, when neither end is planted, the trees are equal to the number of segments minus 1; 2, when only one end is planted, the trees are equal to the number of segments; 3, when both ends are planted, the trees are equal to the number of segments plus 1. It was at this time that Mr. Liang barked out an order, "Okay, stop!" The students in the front row turned their heads and looked at Mr. Liang. Mr. Liang said, "Which student would like to come to the blackboard and write down the ideas summarized by your group?" Everyone scrambled to raise their right hand, and Mr. Liang named Wu Songyang, the leader of our group. Wu Songyang quickly wrote down the results of our group's discussion on the blackboard. Mr. Liang said, "Good writing, please copy these three laws into your textbooks." At this point, a student spoke up, "Mr. Liang, how is a tree equal to the number of broken, broken numbers?" We took a look, it really is the word "broken", the classroom burst into laughter.
ding bell, ding bell ...... the bell rang, this class is finished. This is really an unforgettable math class ah!
An interesting class composition 500 words 14The first class in the afternoon is a science class, Mr. Wang told us in the last class to do experiments in the next class. Out of the desire to do experiments, I returned to the classroom early without waiting for the class bell to ring.
"Ding bell bell", finally got to class. Students returned to the classroom one after another, ready for class. Not long after, Ms. Wang came, only to see her hand carrying a big green basket. The students immediately talked excitedly. After a while the classroom quieted down, Ms. Wang gave each of us a small box in the basket. I couldn't wait to take it apart, and found that inside were some iron blocks with a look of red and blue colors, the teacher asked, "Does anyone know what the iron blocks in the box are?" The students were silent, after a while, finally a student stood up and said, "This is a magnet." Oh, so this piece of iron is called a magnet! The other students suddenly realized. Mr. Wang asked us to look at an illustration in the textbook showing a train suspended on the tracks and asked us to say what we had discovered. Most of the students answered that the train could fly. Mr. Wang shook his head and said, "This train does not fly, but uses the principle that magnets are attracted to the same poles and attracted to different poles. I was puzzled and asked, "Teacher, what is 'homopolar repulsion, anomalous attraction'?" Mr. Wang told us, "homopolar repulsion, that is, put the same two poles of the magnet together, it will produce the force of mutual repulsion; heteropolar attraction, that is, put the different poles of the magnet together, it will produce the force of mutual attraction."
After saying this, the teacher asked us to verify it. I urgently will be a magnet red end, against another magnet iron blue end, suddenly, like a pair of invisible hands, the two magnets firmly squeezed together; I will be two magnets red pole together, strange, like a deep stream between them can not be crossed, is not willing to suck together. Forced them together, as long as the hand is loose, they will immediately pop open.
It turns out that magnets are so magical that when they meet the opposite sex, they are hard to part with each other; when they meet the same sex, they avoid each other. The world of science has this endless anecdotes, which I did not know before. "It's a long way to go, and I'm going to go up and down."
An interesting lesson essay 500 words 15Today in the composition class, the teacher took a bag in his hand mysteriously walked up to the podium and said to us, "Today we will do an experiment to make quail eggs float in the water. The students looked curiously at the teacher how to do the experiment.
See the teacher from the bag out of a quail egg, a plastic transparent cup, a chopstick, a small spoon and a bag of salt.
The experiment began, the teacher first took the cup to receive more than half a cup of water, and then put the quail egg into the cup, only to see the quail egg slowly sank to the bottom of the water. Then, the teacher said to the class, "Everyone watch, I want to let the quail eggs float to the surface." My classmates and I all looked at each other with half-hearted looks. Without further ado, the teacher dug a spoonful of salt into the cup with a small spoon and stirred it with chopsticks, but the quail egg didn't move at all. The teacher put another spoonful of salt, stirred, the quail eggs are still lying at the bottom of the water, refused to come up. I was really worried that the experiment would fail and the quail eggs would not float. Later, only to see the teacher again and again to add salt, stirring, the miracle finally appeared - the quail eggs really floated to the surface!
After the experiment, the teacher told us why the quail eggs will float up the principle. The teacher said, the water is buoyant, so when swimming we will feel the body involuntarily upward. Quail eggs in the water began to sink to the bottom of the water, because the quail eggs heavy, the buoyancy of the water is small; add salt to the water to increase the buoyancy, so the quail eggs can float up.
Today, this interesting composition class, not only so that I learned to write, but also let me learn a little knowledge of science, the harvest is really big ah!
