Decomposition and Composition of 5 1 First lecture, textbook
Decomposition and Synthesis of 5 is the learning content of the first book of the series of textbooks for large classes in Aierfang Kindergarten in the future. According to the age characteristics and life reality of the children in large classes, I try to integrate math activities with game activities, and choose to use the animation courseware Pleasant Goat and Big Big Big Wolf, so that children can intuitively and quickly master the decomposition and composition of 5 in the process of happy games. Through the animated characters and game links that children are very interested in, mathematical problems are put forward, from abstract to intuitive, from easy to difficult, which not only achieves the purpose of cultivating children's logical thinking ability, but also allows children to experience the joy of mathematical activities. This also reflects the educational goal of science in the second part of the new syllabus: to feel the quantitative relationship of things from life and games, and to appreciate the importance and interest of mathematics.
Activity objectives:
1, knowledge goal: master the decomposition and composition of 5; Guide children to summarize the arrangement law of the number of two sides of splitting type; Supplement to preliminary perception 5.
2. Ability goal: cultivate children's analytical ability, observation ability, hands-on operation ability and language expression ability.
3. Emotional goal: stimulate children's interest in learning mathematics and cultivate children's love for learning mathematics.
Activity focus: Let children master the decomposition and composition of 5 and learn to decompose 5 in an orderly manner.
Activity difficulty: by learning the decomposition and composition of 5, feel the addition of 5.
Activity preparation: the theme song of Pleasant Goat and Big Big Wolf, the animation courseware of Pleasant Goat and Big Big Wolf, and some clips. The reason why clips should be used as teaching AIDS for activities is that small clips can be seen everywhere in life, close to children's lives and easy to operate. At the same time, it can meet the needs of our class and reduce the pressure on teachers to play teaching AIDS themselves. Moreover, it can also be put into different regional activities, which not only makes up for the lack of playing teaching AIDS, but also allows children to operate independently.
Second, oral teaching methods
The new Outline points out that the organization of educational activities should fully consider children's learning characteristics and cognitive laws, pay attention to comprehensiveness, interest and activity, and integrate education into life and games. So, first of all, the teaching method I use is the game method. Kindergarten mathematics is a systematic and logical subject, and it is very boring to study mathematics alone. Nowadays, children's education advocates happy learning, so I combine math activities with game activities to let children learn happily in games.
Pleasant Goat and Big Big Wolf is an animated film that children can never get tired of watching, so I made an animated courseware of Pleasant Goat and Big Big Wolf by using children's psychological characteristics. The whole teaching activity is linked by playing courseware, which also reflects the application of multimedia in teaching, so the second teaching method I adopt is multimedia teaching method.
In guiding and enlightening children, I also used the talking method and questioning method, and in summing up, I also used the teaching method.
Third, theoretical study.
The thinking characteristic of large class children is that the seeds of abstract thinking have begun to appear. Their knowledge and understanding of the composition of numbers cannot be instilled by adults. If children have been passively accepting knowledge, they can't cultivate their logical thinking ability. Piaget, a Swiss psychologist, also stressed: "Mathematical relationship is a kind of logical mathematical knowledge, which does not exist in actual objects. Children acquire knowledge of mathematical logic not from the objects themselves, but by playing with them and organizing their own actions in their hearts. " Therefore, it is of decisive significance for children to learn mathematics by operating physical objects. The main learning methods embodied in this teaching activity are: hands-on operation, observation and inquiry.
Fourth, talk about the teaching process
1, design idea
The first link: rhythm, talking into the game.
The second link: the game breaks through. Let me give you a brief introduction to this game: Pleasant Goat invites children to help him break through the three levels set by Big Big Wolf and rescue Meiyangyang from Wolf Castle. Because this game is very challenging and interesting, children's desire to participate is very strong. This is also the focus of the whole teaching activity, and the activities I designed can basically be completed in the second link.
The third link: the small game "driving the train" ends the activity.
The fourth link: activity extension.
2. Activity flow
(a) the beginning part
1, rhythm: Play songs, children dance freely in the music.
2. Teachers teach by example and fully mobilize the enthusiasm of children to participate in games.
(2) Game part
(1) level 1
1, play the courseware and show the task of the first level: please break down the number 5 and say how many ways?
2. Children begin to operate small fragments, and the teacher will summarize the results of children's operations and record them on the blackboard. Through children's operation and observation, they can say that the number 5 has four decomposition methods.
(2) the second level
1, play the courseware and show the second task: please observe the opening and closing formula of the number 5 carefully and think about its arrangement law.
2. Teachers guide children to observe the changes of the split type, one is bigger and the other is smaller, thus summarizing the law of increasing and decreasing in turn.
(3) the third level
1, play the courseware and show the third task: you have learned the decomposition and composition of the number 5. Can you talk about the addition of the number 5?
The children began to operate the small clips again. After the hands-on operation, the teacher will guide the children to know that the decomposition and synthesis of 5 and the addition of 5 can all be reflected in the on-off formula. Through the teacher's guidance, children can easily say the addition of the number 5.
3. Play the courseware and the game is over.
(3) Conclusion.
Game: driving a train. This little game is the consolidation and memory of the decomposition and composition of 5, and it also paves the way for learning the addition and subtraction of 5 later.
(4) Activity extension
Please put the small clip back to the math corner, and further feel the conservation of numbers by operating the clip and the digital card of the math corner.
Lecture 2 of "Decomposition and Composition of 5" is based on "Guidelines for Kindergarten Education". "Mathematics education must let children feel the quantitative relationship of things from life and games, and experience the importance and interest of mathematics; Teachers should guide children to be interested in the phenomena of number, quantity, shape, time and space in the surrounding environment, construct a preliminary concept of number, and learn to solve some simple problems in life and games with simple mathematical methods. " Therefore, mathematics education should be life-oriented and game-oriented. According to children's age characteristics and learning situation, I designed the following activities:
Decomposition, synthesis and learning of 1
2. Stimulate children's interest in active exploration.
3. Friendly exchanges and discussions with peers.
Among the above three activity goals, due to the limitation of children's cognitive rules and age characteristics, the decomposition and composition of 5 are not easy for children to master, so I list it as the focus of the activity; On this basis, it is difficult to guide children to communicate with peers in a friendly way and explore what they have learned.
In order to achieve the goal of the activity, I made the following preparations:
1, knowledge preparation: synthesis and decomposition of 2,3,4
2. Material preparation: multimedia courseware, each person has a set of plates with Mickey Mouse and Donald Duck heads, five little penguins, pens, record cards, drums, and two circles composed of colored stickers and digital cards.
In order to achieve the purpose of this activity, I adopted the methods of creating situations, games and exploring. The reason why situational creation method is adopted is because children's cognition is relatively shallow, and their perception of knowledge cannot be separated from the support of specific things. Creating situations is more conducive to children's understanding and stimulating their interest. Games are the main activities of kindergartens and children's favorite activities. Playing is a child's nature, so games can help children master knowledge. Because children have a strong curiosity and like to explore things, we use this characteristic of children to cultivate their interest and habit of active exploration by means of inquiry.
Children are the main body of learning, so it is very important to choose methods to let children actively participate in exploration activities. According to the content of teaching materials and the characteristics of children's age, I create suitable conditions to improve children's cognitive ability and practical ability closely around the activity goals. The main application methods are:
1, operation trial method: let children operate, middle school teaches middle school, and let every child try.
2. Group discussion: Through children's communication and discussion, let children know the differences of 5 and improve their language expression ability and logical thinking ability.
In order to achieve the activity goal, I designed the following activity plan:
First, create a situation and import it.
Show the multimedia courseware "Mickey Mouse and Donald Duck invite five little penguins to their home at the same time, let the children guess whose home the little penguins will go to?" Through this suspense, stimulate children's curiosity and thirst for knowledge, and mobilize children's interest in participating in activities. This is what children will say. Who will be a guest? The teacher will guide the little penguin to visit two houses. How many ways will there be? Let the children take out five little penguins, two plates, pens and record cards with the heads of Mickey Mouse and Donald Duck, and let the children start to operate. Children divide penguins into two parts, put them on two plates respectively, and then ask children to count the number of penguins in each plate and record the results on a record card, one for each type. Then communicate in the group and tell your partner your opinion. In the process of decomposition, some children may not get comprehensive scores, and teachers should give individual counseling. Finally, the teacher summed up several points. According to the principle of "try to create conditions for children to actually participate in inquiry activities, let them feel the process and methods of scientific inquiry and experience the fun of discovery" in the Guiding Outline of Kindergarten Education, I let children try to operate, let children divide 5 into four points in two parts in the initial perception operation, and let children tell the operation process and results, which is not only the feedback of activities, but also the cultivation of children's language expression ability and logical thinking ability.
Second, game integration.
Consolidate the decomposition and composition of 5 with the game of "listening to drums and running circles" The teacher put two circles composed of colored stickers in the middle of the activity area, and asked five children to stand outside the two circles at will. When the teacher beat the drum, they walked around the circle. When the drums stopped, the children jumped into two circles and stood still. The teacher asked other children how many people are there in each circle, that is, how many can five be divided into? How many people are there in two circles? How many can five be divided into? The game is repeated several times until several points are over. The "Guidelines for Early Childhood Education" points out that "provide rich and operable materials to provide conditions for each child to use a variety of senses and ways to carry out inquiry activities". Therefore, this link is mainly to let children use their mouths and brains in pleasant games, which not only trains their judgment ability, but also improves their thinking ability. At the same time, consolidate the five laws and train children's language expression ability.
Third, the extension of activities.
1, the teacher plays Mickey mouse and greets the children, and gives each child a digital card, so that the children can combine freely. As long as it is combined into 5, it will reward a little star, correct the wrong child in time, let the child deepen his impression of the decomposition and composition of 5, and improve his thinking ability.
2. Introduce the record sheet to the family, let parents participate in the interaction, fill in the correct smiling face, and bring it back to the kindergarten the next day, so that children can pass on information and promote family interaction.
In the whole activity, we strive to stimulate children's interest, cultivate children's inquiry ability, make children happy in learning, have fun in playing, and actively participate in activities, so as to achieve activity goals, solve important and difficult problems, and develop children's thinking ability and expression ability.
