Elementary school math teacher interview, trial lecture, understanding RMB
The following is an example of a primary school math teacher interviewing and trying to teach Understanding the RMB: ##1. Introduction (1 - 2 minutes) Students, in our daily life, there is something very important. We need it when we go to the store to buy our favorite stationery and snacks. Do you know what it is? (Pausing for a moment to guide the students to answer) Yes, money. The money in our country is called RMB. Today, the teacher will bring everyone here to learn about the RMB. ##2. New teaching (5 - 7 minutes) 1. ** Understand the types and units of RMB ** The teacher has some pictures of the RMB here (you can show the prepared pictures of the RMB with various currency values or take out the simulated RMB props). Everyone, take a closer look. What's the difference between these RMB? Some students noticed that some of the notes had the word "Yuan" written on them, some had the word "Jiao" written on them, and some had the word "Fen" written on them. Very good."Yuan, Jiao, Fen" was the unit of the RMB. Now, let's classify these RMB according to units, okay? (Please come up to the stage to do the classification.) 2. ** Understanding RMB of different currency values ** Let's first look at the yuan. Everyone, look at this 1 yuan note. What color is it? What was the pattern on it? (Guide the students to describe the characteristics of 1 RMB) What about this 5 RMB note? In this way, let's get to know the RMB of 10 yuan, 20 yuan, 50 yuan, and 100 yuan. Next, let's take a look at the RMB in the unit of "jiao". What do 1jiao and 5jiao RMB look like? (Ask the students to observe and describe it carefully.) Finally, let's look at the "cents" as the unit of RMB. Although the cents are rarely used in daily life now, we still have to know what are the characteristics of the 1-cent, 2-cent, and 5-cent RMB? (Guide the students to describe the characteristics of the penny.) 3. ** Conversion of RMB ** Students, the teacher is going to test everyone now. If a teacher had one yuan and wanted to exchange it for dimes, how many dimes could he exchange it for? (Guide the students to think and answer. According to the answer, 1 yuan = 10 cents.) Then how many points does 1 cent equal? (For example, 1 small eraser is 1 point, and 10 small erasers are 1 angle, which means 1 angle = 10 points.) Then how much angle is 2 yuan? (Guide the students to use the knowledge they have learned to answer and consolidate the conversion relationship) ##3. Consolidating (1 minute) Now, the teacher would come up with a few small questions to test everyone. The teacher has the price tags of some products (you can show the cards with the prices, such as pencil 30 cents, notebook 5 yuan, etc.). If the teacher gives you 1 yuan to buy a pencil, how much change should the salesperson give you? (Please stand up and answer. Consolidating your knowledge through this kind of real-life practice.) ##4. A summary (0.5 minutes) Alright, today we got to know about the RMB. We learned that the units of the RMB are yuan, jiao, and fen. We also learned the conversion between yuan, jiao, and fen. Which student can stand up and tell us what you learned today? (Invite a student to summarize, and then the teacher will briefly add.) ##5. Homework (0.5 minutes) After class, please go home and play a game called "Little Store" with your parents. You can use the simulated RMB to buy and sell things. In this process, you will have to use the RMB knowledge we learned today. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Elementary school mathematics second grade second volume corner understanding
In the second volume of the second grade of elementary school mathematics, the understanding of angles included the following contents: 1. ** The definition and composition of an angle ** - An angle was a geometric figure formed by one or more rays intersecting at a common end point. This common end point was the apex of the angle. The rays that formed the angle were called the sides of the angle. The angle was usually represented by the symbol "". For example, ABC represented the angle ABC. A corner had one apex and two sides. 2. ** Horn classification ** - ** Right angle **: An angle equal to 90 degrees is a right angle. One could use the right angle on a triangular ruler to compare to determine whether a corner was a right angle. - ** Sharp angle **: An angle less than 90 degrees is an acute angle. For example, when the hour hand is at 10, 20, 10, or 110, the angle formed by the minute hand and the hour hand is an acute angle. - ** Obtuse angle **: An angle greater than 90 degrees but less than 180 degrees is an obtuse angle. For example, when the hour hand is at 40, 50, 70, or 80 degrees, the angle formed by the minute hand and the hour hand is an obtuse angle. 3. ** Comparing the sizes of the horns ** - The size of the angle depended on the angle between the two rays. The larger the angle, the larger the angle. When comparing the size of an angle, one could use the overlapping method. First, the two vertexes were aligned, and then one side of the two angles overlapped. Looking at the position of the other side, the corner of the other side on the outside was large, the corner of the other side was the same size, and the corner of the other side on the inside was small. 4. ** Angular measurement and tools ** - The most basic unit of measurement for angles was degrees, which divided a circle into 360 degrees. The tool used to measure the angle was a protractor. The protractor had two inner and outer scale rings, corresponding to 0 degrees and 180 degrees respectively. When using a protractor to measure an angle, the center point of the protractor should be coincided with the apex of the angle, and the 0 degree scale line should be coincided with one side of the angle. Eyes should be aimed at the inner scale circle of the protractor, and the corresponding degree of the other side should be found, which is the size of the angle. At the same time, attention should be paid to the accuracy. Try to choose a suitable protractor or measure the average value many times. 5. ** A corner in life ** - On the clock, the minute hand and hour hand formed different angles at different times. For example, at 30 or 90 hours, the angle formed by the minute hand and hour hand was a right angle; at 3:30 in the afternoon, the angle formed by the minute hand and hour hand was a right angle. 6. ** Corner related teaching activities ** - Students could learn how to recognize and compare the sizes of the horns through folding paper. For example, the teacher would ask the students to prepare a square piece of paper before class. After class, the teacher would first use the pictures in the class to find the corner with the child, and then find the corner in the classroom. When the students had an understanding of the corner, the students would fold a corner themselves, and then try to compare whose corner was bigger. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is an essay suitable for a third-grade primary school student to write about pandas: The Cute Giant Panda The giant panda was a unique treasure in China and a favorite animal of people all over the world. Its appearance was very unique and cute. Its fur was black and white, as if it was wearing a black and white fashion coat. Two furry ears stood on its round head like two little balls of fur. The most eye-catching thing was its pair of big dark circles, as if it was wearing a pair of oversized sunglasses, making it look funny and cute. Below the eyes was a small nose, and below it was a mouth that was always chewing bamboo. Its limbs were short and strong. Although it was round and chubby, this did not affect its movements. It also had a short tail trailing behind it, like a little ball of fur. The living habits of giant pandas were also very interesting. It loved to eat bamboo. It sat on the ground and hugged the bamboo tightly with its two front paws. Then, it used its sharp teeth to bite off the bamboo and chewed it in big mouthfuls. It was eating very well. It was also very good at climbing trees. Although it was usually slow, it was very flexible when it climbed trees. Sometimes, it would climb up the tall trees to bask in the sun or take a nap. Giant pandas slept in all sorts of strange postures. Sometimes, they lay on their backs, revealing their round bellies. Occasionally, they would scratch their bellies with their claws, looking charmingly naive. The giant panda was not only a national treasure of China, but also an important symbol of the world's biological variety. Since they are so few in number, we have to protect them well and let them live happily on Earth.
