Classified statistics of mathematics teaching plans for large classes in kindergartens
Activity objectives:

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 the car of this size 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. )

Encyclopedia: classification refers to classification according to category, grade or nature.
