The design background of kindergarten large class math teaching plan1Decomposition of 6.
After learning the decomposition and synthesis of numbers within 2-5, a child suddenly asked me this day: "teacher, I know the decomposition and synthesis of 5, but we will be six years old soon." Can you tell us the decomposition and composition of 6? " Children have had some experience in the composition of numbers. I try to let the children do it by themselves, then record the results, find the law of decomposition and composition under the guidance of the teacher, let the children play middle school, and achieve the combination of activity goals and children's interest optimization. Recently, we learned two poems, The Name Card of the Tree and Letter from Mother Tree. The children know that autumn is coming, and Mother Tree tells the little animals to prepare for winter. Combined with the content of poetry, this activity tries to divide the house for small animals and learn the decomposition of 6.
moving target
1, children feel the decomposition of 6 through independent exploration and hands-on operation, and master the five points of 6.
2. On the basis of the decomposition and composition of perceived numbers, master the laws of number increase and decrease and mutual exchange.
3. Develop children's ability to observe, analyze and record, and cultivate children's interest in mathematics.
4. Experience the fun of math group games.
5. Cultivate children's comparative judgment ability.
Emphasis and difficulty in teaching
1, focus: perceive the relationship between the whole and the part, learn and record the five points of 6.
2. Difficulties: Summarize the law of decomposition and synthesis of numbers within 6.
Activities to be prepared
Teaching AIDS: a large wall chart (there are two houses on the map, and there is a decomposition of 6 spaces on both sides of the map), 6 panda cards, markers and recording paper.
Learning tools: each child has a picture (there are two houses on the picture, and there are spaces on both sides of the picture with a score of 6).
Each person has 6 animal cards, pencils, erasers and 1-5 digital cards.
Activity process
(a), the beginning part
1, import:
Teacher: Autumn is coming. Mother Dashu is busy writing letters, writing here and there, and all the red leaves and yellow leaves are finished.
Q: Who has received the letter from Mother Tree? Guide children to answer which small animals have received the letter from mother tree.
Q: What did Mother Tree write in her letter? Tell the animals to prepare for the winter.
Teacher: The little animals received the letter from Mother Tree and built many new houses. They are going to spend the winter in the new houses.
2. Show the big wall chart, which leads to "the decomposition of 6"
Teacher: The panda family has been allocated two houses. There are several pandas in the panda family (including six with children) to display the digital card of "6".
Teacher: How to divide six pandas into two houses? The panda is worried. I don't know how to divide it. There are several kinds of distribution. Please tell the children.
(2) Basic part
1, please help your little animals to divide the house.
(1), children observe their learning tools, talk about what small animals they are and count the number of small animals (6).
(2) Children divide six small animals into two rooms and record the results of each division.
2. Let the children talk about the results of their own points. The teacher recorded the children's division of labor on the record paper.
3. The teacher summed up the children's points and summed up the five points of "6".
4. Observe the disorderly division of children and guide the orderly decomposition of learning to form "6".
(1), the teacher demonstrated that six pandas were divided into houses, and counted the number of small animals in the two houses with the children, and recorded the results. "6" can be divided into 1 and 5,2 and 4,3 and 3,4 and 2,5 and 1.
(2) Children observe the decomposition formula of "6", initially grasp the orderly decomposition and composition of "6", and understand the law of number increase and decrease and exchange.
5. The child divided the house for the small animals for the second time, tried to break down the "6" in an orderly way, and recorded the results of each division.
(3), the end part
The game "find friends"
Each child chooses a digital card (1-5) to wear, and together with the music of finding friends, find the child with the number "6".
Teaching reflection
According to the spirit of the new syllabus, the design of this activity requires children to "perceive the quantitative relationship of things from life and games", and also pays attention to children's ability to explore, operate, communicate, solve problems and cooperate. This semester, the children in our big class have learned the decomposition and composition of numbers within 2-5, and the children have had some experience in the composition of numbers. I try to let the children do it by themselves, then record the results, find the law of decomposition and composition under the guidance of the teacher, let the children play middle school, and achieve the combination of activity goals and children's interest optimization. The design idea of the activity comes from two poems we recently learned, namely "The Business Card of the Tree" and "Letter from Mother Tree". The children know that autumn is coming, and Mother Tree is busy writing letters. Mother tree told the little animals to get ready for winter. According to the content of the poem, this activity tries to divide houses for small animals. Children can feel the decomposition of 6 through exploration and independent operation and master the five divisions of 6. On the basis of digital decomposition, they can master it
The activity revolves around allocating houses to small animals. Each child is assigned to six small animals, which are different, including six puppies, six kittens, six rhinos, six elephants and six lions. Every child also has a picture with two houses. Lovely teaching AIDS, coupled with children's happy mood to help small animals divide the house, fully mobilized the enthusiasm of children to operate and explore independently. In the process of assigning houses to small animals for the first time and recording them, the children found five points of "6" through operation and exploration. When showing children's housing allocation records, some children didn't find the five points of "6", and some separate figures didn't add up to "6". This is the first time a child has tried recording. I will pay more attention to those who have not mastered it in the next link. Next, guide and observe the disorderly division of children. The teacher will demonstrate that six pandas are divided into houses, count the number of small animals in the two houses with the children, and record the results of the division. "6" can be divided into 1 and 5, 2 and 4, 3 and 3, 4 and 2, 5 and 1, which leads to the orderly decomposition of learning to form "6". Children will observe "6". When children divide small animals into rooms for the second time, they master the orderly decomposition of "6" and record the results of each room division. The activity ended in the cheerful atmosphere of "Find Friends" game, and the children realized the combination of activity goals and children's interest optimization through exploration, operation, communication, playing and learning.
The goal of "Decomposition VI" 2. Mathematics teaching plan for large classes in kindergarten;
1. Learn the decomposition and composition of 6, deepen the understanding of the relationship between the whole and the parts, and be interested in division and activities.
2. Know that every number has several division and combination methods that are smaller than this number 1.
3. Write the number 6.
4. Experience the life of mathematics and the fun of mathematics games.
5. Be able to cooperate with peers and try to record the results.
Activity preparation:
1. A photo of an old man, 16 fish and two goldfish bowls, a disk, a digital card, and some symbols on and off.
2. Each child has six hats, stones, buttons and beans, some digital cards and symbols for opening and closing, and each child has a recording paper.
Activity flow:
1. Show pictures of six goldfish and two goldfish bowls and ask a question: Grandpa bought six goldfish. He wants to keep these six fish in two goldfish tanks, and asks that there are goldfish in each tank. What can he do? Can you help grandpa? Ask the children to say the division, and the teacher posts the physical decomposition diagram and the digital decomposition diagram (not necessarily in order).
Second, please take six bottles, stones, buttons and beans and divide them into two piles, each pile requires different points. Say how it is divided, how many ways it is divided, and try to record it.
Third, show six disks and symbols on the blackboard, let a child come up and put out his points one by one, and then let a child put out the corresponding decomposition formula with a digital card. Guide children to observe and read several points of 6, and know that there are five points.
Four. Discussion: 3 How many methods are there? 2 How many ways are there? Put the decomposition formula of 2~6 on the blackboard one by one to guide children to find that there are several points less than this number 1.
Exercise: Open the book, add pictures or fill in the decomposition formula of 6.
Activity expansion:
Further review the composition and writing of Consolidate 6 in the workbook.
Teaching reflection:
Mathematics comes from reality, exists in reality and is applied to reality. Mathematical process should be a process to help children turn practical problems into mathematical problems. The content selection of educational activities should be close to children's life, and choosing things and problems that children are interested in will help expand children's experience and vision.
The activity goal of "decomposition of 6" in the math teaching plan for large classes in kindergarten.
1, learn the composition of 6, and understand that 6 has five different methods, which can be split and combined in order.
2. Perceive the complementary relationship between two partial numbers.
3, preliminary training observation, comparison and reaction ability.
4, like math activities, willing to participate in various arithmetic games, and cultivate rebellious thinking.
Activities to be prepared
Courseware and teaching AIDS
Activity process
First, the quiz game "Answering Songs", review the decomposition of numbers within 5.
Teacher: "Let me ask you, little friend, how much is 3 divided by 2?"
Teenager: "tian teacher, tell you, 3 can be divided by 2 and 1."
Teacher: "Let me ask you, little friend, how much is 5 divided by 4?"
Teenager: "tian teacher, I'm telling you, 5 can be divided into 1 and 4."

Second, the decomposition of operational exploration 6.
1. Give each child a bag of flowers of different sizes, colors and shapes.
Teacher: "Today, the teacher brought a bag of gifts to every child. What is it? " "What's the difference?"
2, children's operation exploration, the decomposition of perception 6.
Teacher: "The teacher gave each child the same six flowers. Please divide it into a little according to the characteristics of flowers and see how much can be divided. "
Children's operation, teachers' tour guidance.
3. The child tells the result of the operation and the teacher demonstrates the composition on the computer.

4. Guide children to observe the ingredients and look for the decomposition characteristics of 6.
Teacher's summary: 6 points and 5 kinds. The number on the left of each group is larger than the number on the right 1, and the number on the right is smaller than the number on the right 1. This decomposition method is called complementary method.
Third, show the consolidation and decomposition of computer animation games 6.
1, teacher: "Children all know the decomposition method of 6. Now let's play a game of scrambling to answer. The teacher asked questions and the children answered them. If you answer correctly, you will be praised by the little penguin. If the answer is wrong, the little penguin will fall. "
2. The computer shows the decomposition fill-in-the-blank form of 6, and the children answer in the form of quick answers. The answer is correct. The little penguin jumped up and said, "Hey, you are great." Wrong answer, the little penguin fell to the ground with the music.
Activity reflection
The decomposition of learning number can help children understand the relationship between whole and part, part and part, further deepen their understanding of logarithm concept and lay the foundation for learning addition and subtraction. The decomposition of learning numbers is somewhat difficult for children and not easy to master. Children can really understand and master the decomposition of numbers only by perceiving them in actual hands-on operation. Therefore, in this activity, I focused on children's operation exploration, so that children can find the decomposition method of 6 in the operation, then assist the teacher's summary, so that children can have a clear understanding of the decomposition of 6, and finally consolidate it in the form of games, so that children can consolidate their knowledge in a relaxed and happy atmosphere. However, due to individual differences in children's ability to operate, analyze and summarize, some children can't fully master all the decomposition methods of 6, so they need individual guidance in future self-selection activities.
