Mathematics teaching plan for large class in kindergarten of "No.4 Normal University" 1 Activity objective:
1. Learn to divide an object into four equal parts.
2. Explore the methods of bisection of various objects to stimulate children's interest in bisection.
3. Cultivate children's ability of observation and comparison.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Develop good qualities of thinking, doing, studying hard and being happy to learn.
Activity preparation:
Learning tools: there are several shapes of graphics, each with an operation paper and scissors.
Teaching aids: two house maps.
Activity flow:
First, lead in and learn the quartering of circles, ellipses and triangles.
1, Teacher: There are many small animals living in the forest, but today's strong wind and heavy rain have blown out the window paper of the small animals' homes. Are the children willing to put up enough papers for them?
2. Show me the map of the pigsty
Teacher: Come and have a look, children. Whose home is this? What shape is the window of piggy's house? (Circle, ellipse, triangle) Piglet wants the child to divide enough paper into four parts of the same size. Can children do it? 1, the child began to divide the circle, ellipse and triangle into equal parts.
(1) The teacher put forward the operation requirements: choose a good enough piece of paper, fold it in half first, divide it into four equal parts, then cut it according to the crease and spell it again.
(2) Encourage children to choose a variety of graphics for division.
(3) Ask individual children to demonstrate their own division on stage and post their own operation results on the window.
(4) The teacher summed up the concept of quartering: dividing a figure into four parts of equal size is called quartering.
Second, learn the quartering of various squares.
1. Show me the photos of the kitten's house. Teacher: Just now, we put up all the enough papers for the pig. Piggy is really happy. But the kitten is still very sad. Let's help the kitten, too. Look, what is the shape of enough paper in the kitten's house? (square)
2, the child began to divide the square into four equal parts.
(1) The teacher asked for operation: Can you divide this square paper into four parts? Kittens will let children divide them in different ways. would you like to have a try？
(2) Ask individual children to demonstrate their own division on stage and post their own operation results on the window.
(3) The teacher summed up four quadrants.
Third, children explore various quadrants of a rectangle.
1. Show me the photos of the rabbit's house. Teacher: the children's skills are known to the rabbit. The rabbit also wants to ask you for help. What is the shape of enough paper for rabbit's house? (Rectangular)
2. The child began to divide the rectangle into four parts.
The teacher put forward the operation requirements: children can come up with different ways to divide it into four parts, stick one part on the window and then divide the other part to see who gets the most.
3, individual children on stage to show their views (different views)
4. Teachers and children summarize five methods of rectangular quartering.
The teacher demonstrated the sixth most difficult rectangular division.
Fourth, end the activity.
Teacher: Just now, our children put enough paper on the animals. The animals are very grateful for your help. Besides these figures, what other figures can be divided into four parts? Please wait a moment, look in the classroom and have a try.
Activity reflection:
The concept of quartering is not difficult for children in large classes next semester, but it is not easy for children to really understand the specific methods. Therefore, in this activity, we designed different links to guide children to fold, divide, cut and spell themselves, and explore step by step, so as to get the differences of various graphics. The activity process is from easy to difficult, step by step, which is suitable for children's age characteristics, cognitive characteristics and operational characteristics. Judging from the operation of children, most children can actively participate in the operation activities, boldly think of different ways of dividing various graphics, and quickly master the basic methods. For individual difficulties, they can also be inspired and promoted under the tips of teachers or companions.
The whole activity enables children to master four parts of knowledge in doing, playing and learning, which embodies the teaching concept of the new syllabus, so the effect is still good. However, it is also found that the homework data is not prepared adequately, which may be a calculation error. In addition, more consideration should be given to the placement of operating materials, so that the activity effect may be more perfect.

Activities to be prepared
A picture of a square flower bed, several flower bed cards in various shapes such as rectangle, circle and ellipse; Scissors; glue
Activity process
(A picture import, leading to the topic
1. Show pictures of typical flowers in four seasons: winter jasmine, lotus, chrysanthemum and plum blossom.
Teacher: Here are some flowers in a certain season. Can you tell me in which season they bloom?
Under the teacher's demonstration, the children draw these four kinds of flowers on white paper and cut them out.
(B) examples of operation, understanding of knowledge
1, showing square flower beds.
Teacher: A small flower bed will be built in Teacher Pei's yard to plant the four kinds of flowers just now. Please help me find a way to plant four kinds of flowers in this flower bed, so that each flower occupies the same space. (Children speak freely)
2. Teacher's summary: It is necessary to divide the square flower bed into four pieces with the same size to ensure that the flowers of the four seasons occupy the same position.
Teacher: Look at this square flower bed. How can we divide it into four pieces of the same size on average? How to divide it? Are there any other children who are different?
4. Teacher's summary: By folding the square in half, you can get four flower beds with the same shape and size.
5. Teacher: Let's think, children. Where have you used the method of folding in half in our life? Organize skipping rope, folding handkerchief, etc. )
(C) problem expansion, sublimation classroom
1, showing various shapes of paper (rectangle, circle, ellipse). Take the children to know some of these numbers.
Teacher: There are many flower beds of various shapes in the garden, all of which should be planted with flowers of four seasons. Please try to divide the flower bed into four pieces of different sizes.
3. Assigning tasks, children can choose a flower bed with their favorite shape from three kinds of graphics for equal activities.
4. Complete the task and communicate the results of the challenge:
Who got the rectangular flower bed? How to divide it? Is there any other way?
(2) How to divide the round flower bed into four pieces on average? How do you divide it?
(3) Which shape is the same as the oval flower bed?
The children stick the flowers painted at the beginning of the class on the flower bed.
(4) Extended activities
Think about it, can a triangular flower bed be divided into four flower beds of the same size? How to divide it?
Activity reflection:
In today's math teaching, I have prepared some figures (square, triangle, circle, rectangle, etc. I invite the children to divide the circle into two parts with their own brains, and the two parts should be the same size. Stimulate children's interest, interest is the best teacher for children to learn. Only in this way can we effectively interact with children in teaching. Children are willing to try, let them do it themselves, let them concentrate on how to divide the object into two parts, and also boldly try various methods. However, children are unfamiliar with the word "bisection" and need the help of teachers to better understand it. Through this link, children's interest in learning is improved, and children's mathematics learning becomes a voluntary and happy thing. Also let the children concentrate their thoughts and start to study how to divide them into two parts. After learning dichotomy, the concept of division has been initially formed. The next four parts will be easier for children to master.
The next step "dividing the cake" is to let the children divide the cake into four parts. This material is very good, let children realize that many scenes in life are full of mathematical knowledge, let children learn independently and enjoy learning from it.
After the whole activity, the children gradually realized that it is an effective method to solve practical problems by using mathematical knowledge. Over time, children will consciously think about problems in real life from the perspective of mathematics, and then solve problems, that is, use mathematical knowledge to solve problems in real life. I gained a lot through this activity. As a teacher, I should pay more attention to the importance of mathematics in teaching.

Show a piece of paper with numbers. Ask children to introduce which numbers can be divided into four parts and demonstrate how to divide them into four parts. Teachers and children should check together.
Fourth, experience summary:
For the sake of fairness in life, we often use equal division. I hope that children can apply the equal division method we learned today to their later lives, so that they can divide quickly and fairly and avoid unpleasant quarrels.
Verb (abbreviation of verb) activity extension: share food.
Teacher: Mother Bear wants to give you some food to thank the children for helping her baby bear. Please divide the food that can be divided into four parts. And give it to the guests and teachers to share. You can't share dormitory food with your partner.
Reflection after class:
All the children in the class have learned dichotomy. In the process of organizing learning, I found that children are very interested in dichotomy and have the desire to continue learning, so I designed this activity on the basis of children's learning dichotomy.
Before designing this activity, I considered the interest of the activity. Even the children in the big class, how to learn to learn and learn the graphic quartering in happy games? Therefore, I chose the way that the story runs through the situation, and used courseware and animation to stimulate children's desire and interest in learning. Judging from the whole activity scene, the children showed positive performance, strong interest, serious participation and bold exploration. In addition, in the process of learning quartering, teachers guide children to learn quartering step by step in the process of exploration and hands-on operation. From simple circle to square to rectangle, step by step, following the law of children's learning and development. In the process of sharing the quartering method, teachers pay attention to guiding children's habit of expressing as a whole and promoting the development of children's language logical thinking ability. From this, the teacher also helped Bear to find ways to let the children know how to help others, know how to share, and experience the happiness after helping others. In the last part, the teacher guides the children to apply what they have learned to their lives and connect them with real life.
Activities also have many shortcomings, such as the time of activities. When grasping, we should arrange the links more compactly and compress the short parts again.
Chapter 5 Activity Purpose of Mathematics Teaching Plan for Large Class in Kindergarten of "Four Teachers"
1, the significance of quadrupling children: after quadrupling, each share is the same size, so we can compare the relationship between the whole and the parts.
2. Explore the quartering of different objects and materials, develop children's ability to observe and try, and improve their ability to solve practical problems.
Activities to be prepared
1. The walls around the activity room are lined with houses with small animals.
2. Each group has two small baskets (one basket contains a number of rectangular, round and oval colored papers, and the other basket contains scissors, pencils, lines, rulers and other tools), and a number of square papers are placed on the table.
3. Prepare a basket of special materials for each group, such as sawdust, soap, cloth, ribbon, plasticine, etc.
4. Paste, several rags and a magnetic blackboard.
Activity process
First, let children help small animals and arouse children's interest.
Teacher: Children, are you happy that we came to the Animal City today? The little animals want to ask our children a favor today and put up enough paper for the beautiful house they just built. Because the enough paper bought from the store was too big, I couldn't use it until I whispered that I divided each piece into four parts in a toothpaste, and no small animals could divide it. Are children willing to help small animals?
Second, the first attempt: quartering
1. The teacher tried to divide the square into four equal parts.
Teacher: Now, would you please have a try and see how to divide the square enough paper into four parts of the same size?
Children try to operate and divide the square into four parts. Teachers patrol and observe children's operations, praise children who have done well in the exam in time, and encourage children to think about how many points they have.
3. Ask questions after the trial operation.
Teacher:
(1) Please tell xx children how you divide it. How do you know if these four copies are the same size? (Comparison by overlapping method)
(2) Which children have something in common with him? Which children are different from him?
4. The teacher showed the children the three divisions of a square on the magnetic board, and then asked the children to compare the relationship between the whole and the part.
5. summary.
Teacher: dividing a thing into four equal parts like this is called quartering. After quartering, each part is the same size, each part is smaller than the original whole, and the whole is larger than each part.
Third, the second attempt: quartering other figures (rectangle, circle, ellipse, etc. )
1. Let the children put enough paper on the small animals, and the teacher makes a second attempt: divide other graphics into four parts.
Teacher: It's clever of the children to think of so many ways to divide the square into four parts, but the windows of small animals are of various shapes. Let's try, divide the enough paper of other shapes into four parts, and then help the small animals stick it up, shall we? Please gently open the towel, which contains enough paper of other shapes.
"Four Teachers" kindergarten large class math teaching plan 6 I. Activity objectives:
1, understand the meaning of quartering, and be willing to explore various quartering methods for squares and rectangles.
2. Perceive the relationship and composition between the whole and the part, and experience the happiness of solving problems through observation and comparison.
Second, the activity preparation:
Teacher: PPT courseware and two round cards.
Children's operation materials: several square and rectangular graphic cards, scissors and templates.
Third, the activity process
1, Xiong sub-topic
Teacher: Today is the body of Little Bear Yuanyuan and Huahua. Friends gave them a cake. They were very happy. Yuanyuan said, Let's share the cake. We should eat as much as we want. How do two bears eat the same amount of cake? Why don't you help them divide it?
Ask individual children to introduce the method.
Teacher: Your method is really good. Bear thinks it's fair. It divides an object into two parts of the same size like this. We can say that this division is called dichotomy.
If there are four bears eating a cake together, how to share it?
Show the circle chart and ask some children to come forward and operate.
Teacher: Thank you. Just now, the teacher saw you fold a cake in half, then fold it in half and divide it into four cakes of the same size. This division is called quartering.
2. Explore and try various methods to divide squares and rectangles.
Just now, we helped Bear divide the cake into four equal parts. Now, we use this method to divide other graphics into four equal parts and show PPT. The teacher prepared some graphics for you in the laundry list. Please go to the table gently and try it and see how many points there are. Please tell the teacher and the children how to divide them in the future.
3. Perceive the relationship and composition between the whole and the parts.
Just now, we divided the square and rectangle into four parts in different ways. Now I let the children cut it with scissors (children's operation)
What is the difference between the separated graphics and the original graphics? What's the difference between the divided square and the original square? Taking a square as an example, comparing the size perception of the whole and the part before and after equal division, the whole is larger than the part and the part is smaller than the whole.
The teacher prepared a square template for the children on the table and asked them to put the four parts together into the original whole.
Step 4 exchange discussions
How did you divide it just now? Ask several children with different points to tell stories and show their partners the operation cards.
Summary: The children are great. We not only learned how to divide the graph into four parts, but also learned that they are smaller than the original graph after separation. Let's go back to the classroom later. Those things can be combined into one.
(After the children demonstrate, the teacher will show PPT.
5. Extended activities
