An open class composition
Careful observation is the golden key to improve the writing level. Only by careful observation can we find broken jade from the mineral deposits of life phenomena and grab the shining treasure from the mixed sediment. Without mastering the golden key of "observation", the "iron gate" of composition will never get past. How to write a composition for an open class?

Today, our whole class happily took the bus, sang and laughed all the way to Nanning No.3 Middle School Gymnasium, and had a unique and interesting math open class.

As soon as I came in, I saw a sea of people at the meeting. They are all teachers from all over Guangxi who come to attend classes. After the introduction of the judges at the front desk, a young male teacher began to give us lessons.

This math class is about the parallelism and verticality of quadrilateral. I think, we are only in grade three, can you understand? I put a big question mark in my heart. I saw the teacher play a guessing game for us first. The teacher pulls out one of the numbers, let's guess what it is. Our classmates scrambled to answer, some guessed quadrilateral, some guessed irregular figure. I saw the teacher smiled kindly and turned into a trapezoid with a gentle pull. Then the teacher asked what are the characteristics of trapezoid? Tan Xinghan, the king who raised his hand in our class, immediately raised his hand and answered first: "Only one side of the trapezoid is parallel and the other side is vertical, and it will intersect." The teacher nodded frequently and smiled for everyone to applaud him. I only heard warm applause from the audience, which was deafening. The teacher conjured up a trapezoid and a triangle. Let's think about it. Can these two graphs be merged into one graph? * * * * How many spellings are there? I had a brainwave. It was so simple! So I immediately raised my little hand. The teacher asked me to spell it on the platform. I spelled a parallelogram and proudly waited for the teacher's praise. The teacher asked, do you think of any other graphics? I was stunned. No sooner had I thought of an idea than I raised my hand. Now I didn't think of it at the moment. I scratched my head with my hand and shook my head gently. The teacher smiled and encouraged me. "Great, go down and think about it." The students in the class also raised their hands to answer. Then, I put together a special figure, which is both like a parallelogram and a rectangle. Tan Xinghan also spelled a big triangle. The teacher praised us for being great and coming up with so many figures. At this point, the whole class was in high spirits. Everyone followed the teacher's guidance and summarized, and soon mastered the characteristics of parallelogram.

How time flies! A vivid and unique math class feels like it starts and ends with the bell ringing in Rinrin. I really hope that we can have such an interesting and informative open class again in the future.

Open class composition 2: We will have an open class this Thursday. It is said that many teachers will come to attend classes that day. I am extremely nervous at the thought that there will be many teachers listening to our classes and watching our performances in the back that day. I thought: If I got the wrong answer, I would lose face. Even when I read words, I stutter. That's my natural timidity. Forget it, then don't raise your hand, but if you don't raise your hand, the teacher won't give our group extra points, and it will also bring bad influence to the class. Or I'll raise my hand and not answer. But how is that possible? Forget it, forget it, we'll talk about it then.

In this way, in my heart, Thursday is coming. I found that other students in our class are different from me. They all walked happily to the amphitheatre on the first floor, full of energy and spring breeze. Really, that's what they are. I am not exaggerating at all. I guess they are not as timid and thoughtful as I am. That's all right, teacher. He has a keen eye. He will know my cowardice and won't ask me questions. When we all got to the amphitheater, we quickly found our seats and sat down.

Our Chinese teacher glanced at it a few times, and it was estimated that when he saw the absence of the class, he put his hand down, which meant that everyone should have a rest first. Let's lie prone on the table and have a rest at once. In fact, at that time, we can have a rest there. I think everyone is as nervous as me. The public class is coming soon. How to rest? Sure enough, before we had a rest for a few minutes, a creaking sound suddenly sounded. Everyone looked up from the table and cast a curious look at the door. So the teacher is coming. Everyone's laziness disappeared at once, and several stooges in the class also knew the importance and seriousness of this open class, and sat up straight at once, which had never come out in class.

The text we are going to learn in this class is "Building a Railway to Lhasa". Our teacher has told us this for a long time, telling us to preview carefully, read the text more than five times and write it down in the notebook. Teacher Zhang also said that every student should ask at least ten questions in the book. It can be said that in this way, we basically "rake" every sentence in the book. What we have to do now is to try our best to cooperate with the teacher and not to lose face in class.

"Please look at the topic I wrote. Wait a minute, I want to ask a question. " The teacher's voice interrupted my thinking. I looked at the blackboard and saw the words "building a railway to Lhasa" written by the teacher. We usually say that our teacher writes beautifully, but today he writes more carefully, which makes him more beautiful. When I grow up, I want to write such words, and my thoughts float out of my head. "Yiling, you answer this question." I'm back to reality. No, I can't be wild. See yee ling talking to Kan Kan, thinking is very clear, the answer is also very complete, she is like me at ordinary times don't raise your hand, it seems that she is also prepared.

No, I also want to answer questions, but because I don't usually raise my hand for fear that the teacher can't hear me, I put it down.

"If Xin, you answer ..." Another loud and fluent answer, and the teacher nodded with satisfaction. It seems that the teacher is very happy and the students cooperate well. It seems that our preview is also very effective. The teacher spoke more attentively, and I took notes more carefully. Soon there are many small words in the book, which are my notes.

I don't know how long it took, but with the music, we ended this open class. When I turned to say thank you to them, I heard thunderous applause. We proved to the teacher that we can do our best as long as we work hard.

After this open class, the Chinese teacher was very satisfied with our performance and rewarded us with a snack in the canteen. You know, in normal times, our boss Mr. Zhang is not allowed. Of course, I am even happier that those teachers gave us such a good evaluation.
