Design Intention of "Classified Statistics" 2, a teaching plan for large classes in kindergarten
This semester, there is a special activity about thread in the class. The children were very interested and brought all kinds of threads from home. For a time, lines with different textures, materials, colors and uses appeared in the class. In order to let children know more clearly, I sorted out the classification and statistical activities of lines. Let children know more about the types of lines.
moving target
1. In observation, comparison and discussion, lines are classified in terms of color, thickness, texture and length.
2. Under the guidance of teachers and scorekeepers, learn to design simple statistics by yourself.
3. The operation of language expression makes children's language and thinking develop simultaneously.
4. Cultivate children's observation, analysis and hands-on ability.
5. Take an active part in activities and speak your mind boldly.
Activities to be prepared
1, various lines.
Paper and pens were distributed to everyone.
3. Statistical demonstration diagram.
Activity process
1, provide children with a variety of lines, please observe and compare, and learn the preliminary classification skills by yourself.
Teacher: Today, I brought you many different lines. Please observe them yourself later and see if you can tell how many lines there are.
After listening, the children observed the lines in twos and threes, and became interested in the lines.
Teaching reflection: in this link, teachers can let children observe and compare themselves first, give them enough free space, let them try to classify and stimulate their interest.
2. Teachers guide children to classify according to different characteristics such as color and thickness.
Teacher: Just now, I heard a child say that you can put the same colors together. Let's have a try.
children
Try to sort by color, put the same color together, and count each one when all the parts are ready.
Teacher: What else can it be divided into? Besides the different colors, did you find any other different features? The children are under the guidance of the teacher.
Teachers continue to guide children, so that children continue to think about classification methods in discovery and comparison. Guide children to classify the long, short and purpose, and make classification records.
Teaching reflection: In this link, teachers play an enlightening role, and children are the main body, so that children can discover and speak for themselves, which fully reflects that children are in front and teachers are behind, which can fully mobilize children's initiative in learning.
3. Teachers will record the results of children's observation and discussion on the blackboard, and guide children to design their own statistical charts to record.
A, children see records for operation activities, and statistics of all the records.
B, teachers tour guidance and discover various methods.
Teacher: Just now, all the children thought of many ways to classify them. I recorded everything the children said on the blackboard. Now I want you to think about it and help me design the most beautiful one.
Yang: Teacher, can I design two? ……
Teaching reflection: In this link, the teacher only asks the children to explore and try. The teacher is just an observer, touring to observe the children's works. If children don't answer their questions, teachers don't bother them, which fully shows that children are the main body and are no longer influenced by teachers.
4. Teachers summarize and find different examples. Ask children to introduce their own statistical methods for everyone to learn.
Teacher: Whose is this? Please tell me how you designed it. Why do you want to design like this?
Teaching reflection: In this link, each child's answer will be different. Some children can speak very well, a lot and completely, while others don't know how to express it, but they should be encouraged and praised, because they should affirm their design achievements and enhance their self-confidence.
5. Activity evaluation: This activity design fully captures the hearts of children. Faced with such diverse lines, children can distinguish clearly and remember quickly, so teachers are good at observing, finding problems and starting from life. In the teaching process, the materials are well prepared, and the teacher's language is concise and less inspiring, which also leaves children with time to fully understand and explore. This is a class mainly for children.
6. Keywords: texture, use and statistics.
"Classified Statistics" 3 Activity Objectives of Kindergarten Large Class Teaching Plan:
Through practical activities, learn to classify and count things in life in your own way, and realize the fun and importance of mathematics.
Guide children to actively interact with materials and experience the fun of mathematics activities.
Can think positively and improve understanding ability.
Activity preparation:
The teacher chooses the practice venue (in the kindergarten) in advance, practices in person and makes records, knowing fairly well; Paper and pen.
Activity flow:
(1) Review and consolidate:
1, how much can you count from 1? Count.
2. Fast counting method: 5 digits, 10, 10.
3. Can you write any number within 100? Give it a try (let some children dictate on the blackboard).
(Note: The purpose of this link is to let the teacher know how to master some necessary knowledge about children in practice, so as to better master it in activities. )
(2) Contact with life:
1, what do you meet in life that counts? For example.
2. There are also many numbers hidden in the kindergarten. Please tell the children.
3. What method is convenient for statistics? (every 5 or 10 records, then 5 or 10/0 plots; List statistics and so on. )
(3) put forward the task:
1, grouping statistics and classification statistics of some projects in kindergartens (teachers allocate according to the differences of children's grouping ability).
Group 1: Garage-How many cars are there? How many bicycles? How many motorcycles? How many cars are there in each color?
The second group: the front playground and the back playground-how many trees are there? How many trees are there in the playground before and after? How many big and small trees are there?
Group 3: Elevated Station-How many columns are there? How many white ones? How many green ones? How many round and square ones are there?
(The first three groups let the children "count-classify-count again" to understand that the total score came out.
There are many people going, and the sum of a few points is equal to the total)
Four groups: computer room-how many computers are there? How many teachers are there in the office? How many of them have long hair? How many short hairs are there? (Test children how to solve the "criteria for judging the length of hair")
Group 5: Teacher's Office-How many desks are there in the teacher's office? How many chairs are there? Which is more? How much more? Which is less? How much is missing? (Comparison and one-to-one correspondence of numbers)
Group 6: Overhead on the first floor-how many chandeliers are there? (There are more than 70 lamps, so it is not easy to accurately count the number of children, so check the number of children within 100).
Group 7: Corridor-How many stairs should I climb from the first floor to the fifth floor? How many steps? How many steps are there on each floor? The height of each floor is different, so that children can find more high steps on the floor. )
2. Requirements: ① Reasonable division of labor and cooperation;
(2) Classify, count and record in your own way;
③ Learn to verify statistical data.
3, children perform tasks, teachers observe and understand the practice of individual groups of children.
4, children report the completion of the task, teachers put forward new tasks according to the actual situation.
5. Centralized communication (send one child from each group to report communication):
What are you? What are the statistical results?
② How do you divide your work and cooperate in practice?
Did you encounter any difficulties? Have you thought of a solution?
(4) Assigning exercises after class:
Let the children find out what can be counted at home or in the surrounding environment after returning home, count them and record them in the form of charts.
Activity recording and reflection:
The fourth goal in the field of science in the Guiding Outline of Kindergarten Education mentions that we can feel the quantitative relationship of things from life and games and experience the importance and interest of mathematics. Starting from this goal concept, I designed this activity. After the implementation, the effect is very good, and the predetermined goal is well achieved, and the children's comprehensive ability (cooperation ability, logical thinking ability, judgment ability, ability to overcome and overcome difficulties, adaptability, etc.). ) has been effectively developed in the practice process.
Observation notes:
(1) The fourth group reporter Li Yanxian came to report: "Teacher Huang, our group has completed the task, 37 computers, 17 office teacher, 5 long hair and 5 short hair." Miss Huang: "Five long hairs and five short hairs. How many teachers are there? " "10" Miss Huang: "What about the hair of other teachers in 17?" "Ah-"The whole group of children rushed to the computer room again (the children have realized that there is an error in the classification statistics). The second report said: "Miss Huang, long hair and short hair are too ugly. Some teachers are sitting in the back, others are walking around all the time, and we can't count them. Another teacher with long hair said that we were noisy and had to come down. "
Yes, this classification is too difficult. In addition, I am not sure what criteria should be used to judge long hair and short hair. I was going to try, but the children were too serious. My fault is: I didn't talk to the computer room teacher in advance, and I didn't tell the children what to do when I got to the computer room, which led to the "noisy down" in the end. ) Miss Huang: "Who in your group can solve these problems?" "What we told the teacher was learning, not arguing"; "Everyone speaks in a low voice, which does not affect the teacher's office"; "We each have a row"; "Hair that exceeds the shoulders is long hair, and hair that does not exceed is short hair." Children, help each other, I went to the computer room for the third time. ...
(2) The first group of reporters Su Feinan said, "Mr. Huang, there are 19 motorcycles and three bicycles in the carport. By color, we have always forgotten what color this car is. Let's count it again. " The children are carrying out their tasks seriously, but they have encountered difficulties, but they don't want to give up. After a while, I came back to report: "Teacher Huang, there are 19 motorcycles, 1 1 black, 6 white and 2 red; 3 bicycles, 1 green, 2 white. We use watercolor pens to mark it, so that it won't be messy. " These little guys came up with a solution to the difficulty, and the statistics were very accurate. )
(3) The second group of reporters Du Qianyun said, "Miss Huang, we have finished the task. What is the second task? Can you go to other groups and count them? Wait a minute, let's see if they are right or if we are right. " The children are so enthusiastic about this activity, have the desire to continue to perform the task, and put forward the task they want to perform to the teacher. What a group of independent children. )
The Design Intention of "Classified Statistics" 4, a teaching plan for large classes in kindergarten
The class will carry out the theme activity "Let's Plan" next semester. With the approach of the "Scholarly Childhood" activity, the children's recent planning tasks are coming to an end. In order to introduce the Dragon Boat Festival to other classes more comprehensively on the day of the event, the children in the art district made delicious zongzi and exhibited it on the same day. In order to support the smooth development of children's planning activities, we take the multi-angle classification of zongzi as the goal, make statistical records in the form of groups, and cultivate children's category concept and statistical ability.
moving target
1, which can classify objects from different angles according to different characteristics and count the number.
2. Negotiate with peers to count and record the number of zongzi and enjoy the happiness of cooperation.
Important and difficult
According to the different characteristics of the object, it is enough to classify it from different angles and group the statistical results.
Activities to be prepared
Experience preparation: experience recorded in useful tables.
Material preparation: ppt, several kinds of zongzi in each group, two record sheets in each group, and one display stand in each group.
Activity process
First of all, dialogue can lead to problems.
1. The children all know that our class is planning the activities of scholarly childhood recently. In order to introduce traditional Dragon Boat Festival food to other classes, Teacher Zhu brought many zongzi.
Second, look at the picture and make classified statistics.
1. Divide the zongzi in the picture into two categories.
If you were asked to divide them into two categories according to the same characteristics, how would you divide them?
The teacher concluded: It turns out that we can divide by color or by shape.
2. Add a kind of zongzi and observe the difference.
Now Mr Zhu has taken out some zongzi. Can you find any difference between these zongzi and those just now?
The teacher concluded: the color of the rope is different.
3, 3 people a group of classification and record.
The first time: work in groups of three to find out the most classification methods.
The method summarized by the teacher: We can divide the rice dumplings not only according to the shape, but also according to the color of the rope.
The second time: each group has a record sheet. How many zongzi are there?
Third, organize small shelves.
1. Show tally sheet and observe the shelves.
Show tally sheet and put the zongzi neatly and beautifully on the shelf according to the list. Can you read this tally sheet? Guess what? There are little secrets hidden on the shelves and plates, which will help you put the zongzi in the right place. Let's challenge together!
2. According to the inventory list, divide the small shelves into six groups.
First time: Each group has a tally sheet, a box of zongzi and a shelf. Please arrive at the designated location in groups quickly and arrange the small shelves according to the order.
Teacher's summary method: Classify all zongzi according to tally sheet and the tips on the shelves.
The second time: Add several kinds of zongzi, and according to the tips of tally sheet and the shelves, remove the "disturbing" zongzi that does not belong to this category and tidy up the small shelves.
Four. Promotional activities
1, put a small bookshelf at the door of the class as a prop for the "scholarly childhood" activity and introduce it to other classes that day.
Activity-related pictures
Tally sheet:
Activity summary
This educational activity is based on the theme. In order to introduce the Dragon Boat Festival to other classes on the day of Shuxiang's childhood activities, the children made various works related to the Dragon Boat Festival. There are many kinds of zongzi made by art department. How to put these zongzi neatly and beautifully? So this educational activity came into being. By observing the different characteristics of zongzi, we can make multi-angle classification statistics on zongzi to help children establish the concept of category and understand the record form. In practice, the zongzi are classified and placed in layers, and the role of classification in real life is felt. In the activity of sorting zongzi, cultivate children's self-care ability after entering primary school and help children develop good sorting habits.
