Dear judges, hello everyone, I am candidate XX, and the topic I want to try to talk about today is "Understanding Seconds". Now I'm going to start my trial.
First, the physical import.
Teacher: Hello students!Shh Well, here you go. I listened so carefully.
Teacher: Listen, another voice, you come. Well, great.
Teacher: Let's listen again, okay, come to the last classmate, and tell the teacher, can you imitate this sound?Yes, tick-tock-tock, imitation is really similar!Then you tell the teacher what kind of sound it is, well, it's the sound of seconds.
Teacher: Hey, why do you have different ideas?
Sheng: Teacher, I think this is the footsteps of the old man of time.
Teacher: Your imagination is so rich, and the footsteps of the old man of time are ticking towards us. Let's follow the footsteps of the old man and run towards the New Year together. Tick tock, the New Year is coming, and we are counting down with the old man of time.
Teacher: 54321, the New Year is coming, are you happy?Why are you pouting?Oh, time is too short, such a happy time is always short. Very good, just said that this time is very short, like we measure a very short time, the score is still a short time, we have to realize that this time unit is one second. In this lesson, let's get to know the second. (Board book topic: understanding of seconds).
Second, ** new knowledge.
Teacher: The village chief of Slow Sheep has opened a watch shop, let's go and have a look.
Teacher: When you were looking at it, the teacher had a personal task for you, can you find a tool to measure seconds?
Teacher: Come on. What did you get?Tell everyone, oh, it's an electronic watch (sub-board book: 1, electronic watch).
Teacher: Tell me why an electronic watch can measure seconds?Oh, he meant it had the time on it, 14:15:25.
Teacher: You've found it, come here. He had a clock in his hand. (Sub-board book: 2, clock).
Teacher: Another classmate has also found it, so come on. The one you take is a stopwatch. (Sub-board book: 3, stopwatch) Do you know this thing?(Simulation props) are a tool used by PE teachers to measure your running performance.
Teacher: We borrowed the clock from the village chief's shop to show you. Okay, let's take a look, are you familiar with this?What kind of needle is thick and short?Hour hand, very good.
Teacher: What about this?A little longer than it and a little thinner than it, what kind of needle is it?Minute hand. Teacher: Can you tell the teacher what the minute hand does?Awesome to represent a few minutes.
Teacher: Isn't there one who is particularly busy, and he keeps turning around. What is this?It's the second hand we're going to learn Xi today.
Teacher: What are the characteristics of the second hand?Who's going to talk about it. Here you come. The thinnest and longest needle. Great!The characteristics of the second hand he caught. Thin and long, this is the second hand we learn to Xi today. (Board book: thin and long second hand).
Teacher: What is the second hand used for?Everyone told the teacher together, it's good. Indicates a few seconds. (Board book: means a few seconds).
Teacher: Let's take a look at the clock in the teacher's hand. What is this needle (borrowed utensils: hand. Point to the index finger) points.
Teacher: Why don't you move?Tell me why he didn't move. Teacher, he plays the hour hand. Well, we rarely see the hour hand turning.
Teacher: Okay, let's do it again, (body rotates quickly) What kind of needle is this?Well, it's good, the busiest thing is always the second hand. Teacher: There is another needle, let's ask the last student to play it (the body turns a little slowly). Well, it's a bit slow. This is the minute hand.
Teacher: Can anyone use the knowledge they have learned today to explain the different performance methods of these three students? Okay, here you go. Sheng: Teacher, because the hour hand indicates a long, long time, we saw that he didn't move. The second hand is busy, which means a very short time.
Fourth, the class summary.
Teacher: That's a good answer. What else did you learn in today's lesson?
Teacher: It's very good, I can turn what I have learned into my own knowledge.
5. Assign homework.
Teacher: Before the end of class, the teacher has a task, and everyone should think carefully about what meaningful things can be done in one second. It must be something meaningful. I'll tell the teacher in the next class, okay?Class!
Conclusion: I am done with my trial lecture, thank you for the examiner's patience and listening!Can I erase the blackboard, please?
