Big Class Mathematics Open Class Model ClassThe following are some examples of a large mathematics public lecture:
1. ** Regarding the understanding of numbers **
- You can set up activities to let children find the numbers in their lives, stimulate their interest in numbers, and improve their ability to express the direction of numbers. For example, through conversation, the child could talk about the numbers he found yesterday and the function of these numbers.
- In the teaching of the division and combination of numbers, such as the content of "the division of 10", the goal of the activity could be to explore the division and combination of 10, understand its different composition and decomposition relationship, further perceive the order of the division and combination of numbers, and cultivate scientific inquiry awareness. During the teaching process, the children could be guided to perform the operation of dividing and combining numbers through stories and other situations. For example, the children could help find the cow and then divide the cow, so as to learn the division and combination of 10, which could be expressed with simple formulas. At the same time, the children could feel the convenience and interest of the multi-media in the cooperation and communication.
2. ** Understanding RMB **
- In the public class with the theme of "Understanding RMB", the teacher could show the different face values of RMB and ask the children which face values they knew. From the perspective of food, clothing, housing and transportation, they could not do without RMB, so that the children could understand the importance of RMB in their lives.
3. ** Diagram and Space **
- In the three-dimensional figure recognition teaching, for example, to recognize the cube, cuboid, cylinder, sphere and other basic three-dimensional figures. The teaching goal included allowing students to recognize and differentiate these three-dimensional shapes and grasp their basic characteristics. Through observation, practice, and thinking, the students 'spatial imagination and logical thinking ability were cultivated. During the teaching process, physical models such as cubes, cuboids, cylinders, spheres, and other three-dimensional graphic models could be used to let the children learn the characteristics of various shapes through various links such as talking, dividing, recognizing, and playing. They could correct their vague understanding and connect them with life.
4. ** In terms of pattern exploration **
- In public classes such as Gem Forest, teachers could let children explore different arrangement rules through the forest game, such as the repetition, increment, and arrangement of objects from both sides to the middle, to stimulate children's interest in math games.
- In terms of graphic combinations, teachers could create scenarios to allow children to spontaneously imagine the changes in the graphics, further consolidating the concept of statistics, bringing into play children's imagination and creativity, and making the game run through the entire activity process.

The title of a novel that was once in " Science FictionWorld " was " The probability!" It's about tossing a coin in math class, but the probability of it appearing upside down is not…The novel," The probability!" The author was Liu Cixin, the well-known author of " Sci-fi World." The story was about a mathematics student who was tossing a coin in class, but the probability of the coin appearing on both sides was inconsistent, which made him fall into trouble.
In the story, the protagonist found that the probability of the coin being flipped was uncertain, neither 05 nor 1, but there was a certain fluctuation and uncertainty. This kind of fluctuation and uncertainty led to all kinds of interesting plots and challenges. For example, the result of each coin toss was different. Sometimes it would appear many heads in a row, and sometimes it would appear many tails in a row. This situation would affect the protagonist's studies and future.
The protagonist in the story finally discovered the secret behind the coin and the true meaning of probability through constant thinking and exploration. This story also triggered people to think about probability and uncertainty, and made people more aware of the importance of mathematics and probability.
Big class mathematics observation, game lesson plan and reflection briefThe following is a lesson plan for a large class mathematics observation game:
* * 1. Teaching objectives **
1. Through the game activities, the children's observation, judgment and hands-on operation ability were cultivated.
2. Stimulate children's interest in mathematics activities and improve their enthusiasm for participating in mathematics activities.
* * 2. Teaching preparation **
1. Prepare a number of cards of various colors and shapes (such as triangle, circle, square, red, blue, green, etc.).
2. Number cards 1 - 10.
3. Small toys (such as small cars, small dolls, small building blocks, etc.).
* * 3. Teaching process **
#(1) Diagram Observation Game
1. Show the graphic card
He mixed the different shapes and colors of the cards and displayed them in front of the children.
2. Guiding Observation and Questioning
- Ask the child to carefully observe these figures and tell them what shapes and colors they see. For example,"Children, look at these cards. Tell the teacher what shapes are there? Is there a red card?"
- He asked some questions of comparison, such as,"Which type of card has the most cards? Which color is the least?"
3. Infant Operation
Ask the child to put the cards of the same shape together, then put the cards of the same color together, and then count the number of cards of each shape and color.
#(2) Number Observation Game
1. Show the number card
He took out a numbered card and placed it in front of the child in a random order.
2. Observing and searching
- The teacher said a number and asked the child to quickly find the corresponding number card. For example,"Please find the card with the number 5."
- Then let the child observe these number cards and say the relationship between the adjacent numbers, such as: "What is the number after the number 3?"
3. Number Ranking Game
Ask the children to arrange the number cards in order from small to big or from big to small.
#(3) Toy-watching game
1. display toy
He placed the various small toys that he had prepared on the table.
2. observation and description
- Let the child observe the toy and describe the shape, color, material, and other characteristics of the toy. For example,"What color is this car?" Is it made of plastic or metal?"
- He raised the question of comparison between different toys, such as,"What's the difference between a small toy and a small building block?"
3. classification game
Ask the children to classify the toys according to their own standards, such as by color or by purpose, and ask the children to state the basis for the classification.
* * 4. Reflection on Teaching **
1. the key of success
- In the process of playing, the children showed high enthusiasm and participation, and could complete various observation tasks well, indicating that this play-based teaching method was suitable for the learning characteristics of the children in the upper class, which could attract their attention and stimulate their interest in learning.
- Most of the children could accurately observe, describe, operate, and judge in the observation game of figures, numbers, and toys, indicating that the teaching goal was basically achieved, and the children's observation, judgment, and hands-on operation ability had been trained to a certain extent.
2. deficiencies in
- Some children did not have a clear understanding of the concept of adjacent numbers in the number observation game, and they also made some mistakes in sorting the numbers. Perhaps they were not familiar enough with the size relationship of the numbers, so they needed to strengthen the practice of comparing the size of the numbers in the follow-up teaching.
- In the toy observation game, it was found that the children's vocabulary for describing materials was relatively lacking. Perhaps it was because they did not have enough knowledge in their daily life. In the future, they could add some simple introductions to the characteristics of different materials in the teaching.
3. improvement measure
- For children who could not grasp the concept of numbers well, they could design some small games that specialized in comparing and sorting numbers, such as number solitaire, so that they could deepen their understanding of the relationship between numbers in the game.
- In the future, he would guide the children to come into contact with different materials and enrich their vocabulary. For example, he would introduce the materials of the objects around him in daily life to help the children better observe and describe them.

Hegemony reward probability"We can come to the following conclusion: the probability of an orange card appearing in the Hegemony Card Pack is 5.6%. However, the exact number of orange card draws was not certain, because different card packs had different guarantee mechanisms. Some card packs guaranteed an orange card after a certain number of draws, while others did not have a minimum number of draws. According to the information provided, the probability of obtaining other Hegemony rewards cannot be known.
10,000 words signing probabilityThe signing rate of Zongheng was less than 0.8%. Some authors had received more than 10,000 words of short messages, but this did not accurately indicate the probability of signing a contract for 10,000 words. Although there were cases of successful signing, the overall signing rate was relatively low. There were also cases where the signing threshold was lowered but the quality was not strictly controlled. There were many novels signed on the website but the general quality was not high. Therefore, it was difficult to determine the specific signing probability at 10,000 words.
Hearthstone painting probabilityUnder normal circumstances, an average of 181 normal packs would give out a mutant orange. However, on December 7, 2022, after Hearthstone's patch 25.0 was released, players found that the probability of the game's standard packs giving out mutant orange cards was extremely high. Therefore, Blizzard temporarily closed the opening function of the standard packs to investigate. The special drawing card can be opened through the package.(Use in-game gold coins or real money to buy card packs to activate), participate in activities (You can get a special drawing card bag or get it through the event reward route), participate in the competition (Official Stairway or Single Player Challenge), Combination (There is a certain chance of getting a special drawing version from the normal version), joining the guild (through the guild treasure chest and missions), pre-ordering the super collection (such as the "Lich King's March" super collection can get two special drawing cards), completing the Death Knight Prologue (can unlock the Death Knight profession and get 32 core series cards including 6 special drawing cards for free), etc., but these methods did not mention the specific probability of getting special drawing.
