Countdown lesson plan for kindergarten large class 1 activity goal:
1, starting from any number within 10, and starting from ordinal number or reciprocal number, we can perceive the inherent law between numbers.
2. Improve the sensitivity to numbers and experience the importance and fun of numbers.
3. Actively participate in exploration activities and exercise the agility of thinking.
4. Let children understand simple mathematical principles.
5. Cultivate children's interest in calculation and the accuracy and agility of thinking through various sensory training.
Activity preparation:
1, PPT courseware includes: tour bus, license plate is12345; Countdown to traffic lights10 ~1; The elevator goes up and the floor shows1~10; When the elevator goes down, the floor displays10 ~ 6,6 ~1; Picture of prize area; Turn on the car music.
2. Physical teaching AIDS: red and black tickets, caves, jumping circles, plum blossom piles, grass, etc. marked with the numbers 1 ~ 10 respectively. Marked with the number 1 ~ 10, one for each operator.
3. Operation learning tool information: design license plate number.
Activity flow:
First, directly introduce games to stimulate children's interest in activities.
Teacher: Today, the teacher took you to the amusement city. Are you happy?
Second, observe the license plate number and ticket, and perceive and learn the serial number.
Teacher: This is our tour bus. What is the license plate number?
Teacher: You need a ticket to take the bus. The teacher has prepared the tickets. Let's see what the figures are.
Show the red ticket of 1 ~ 10 to guide the children to observe and count.
Summary: Just now, we started counting from decimals, and the following numbers are more than the previous ones 1. This counting method from small to large is called ordinal number.
Show the 1 ~ 10 black ticket and guide the children to observe and count. Question: What is the name of this counting method from small to large? (ordinal number)
Kid, get in the car and sit down.
Third, feel and learn the countdown when you encounter a red light during your journey.
Children imitate driving with driving music.
The first time I met a red light.
Teacher: There are traffic lights ahead. What light is on now? The red light is on. Can we get there? We should obey the traffic rules. The red light is on and stop the car. There is also a digital timer on the display. Let's take a look and count (guiding children to observe, number 10 ~ 1).
Summary: Just now, we started with the big number, and the following numbers are all less than the previous ones 1. This counting method from big to small is called reciprocal.
Teacher: The green light is on, and we move on (children continue to imitate driving to the music of driving).
The second red light.
Teacher: There is a traffic light ahead. What light is on? Can we go over there? How long do we have to wait? Let's count down together (guide the children to observe and count 10 ~ 1).
Teacher: The green light is on. Let's move on.
Fourth, play the amusement city, and further practice the sequence and countdown.
(1) Take the elevator upstairs and practice the 1 ~ 10 sequence.
Teacher: This is the entertainment city. Go to the amusement city on the 10 floor first! How to get to the 10 floor is faster?
The children imitate taking the elevator, and the teacher reminds the children to stand firm and hold on, and the elevator is about to go up. At the same time, guide children to observe the elevator floor display and count out 1 ~ 10.
Teacher: Here we are 10. Let's get on the elevator safely!
(2) In walking, jumping, drilling and climbing, children practice counting backwards or forwards from any number.
1, guide children to observe the venue completely, practice the sequence and count down.
Teacher: So many interesting things in the amusement park are numbered. Look! This is a cave. What's the number on it? (1 ~ 10) This is a jump cycle. What is the number? (10 ~ 1) This is ...
2. Children are free to play in music and further perceive the inherent laws between numbers.
Teacher: Children! You can choose to play freely, but pay attention to safety and give in to each other! When you play, it depends on which number you start from and which numbers you have passed. Go and choose the number you like to play!
3, exchange gameplay.
Teacher: It's time to have a rest in the amusement park. Please rest in the rest area.
Teacher: Did you have a good time? What did you just play? What date did it start? What numbers have you passed?
Children are free to choose to start with any number or count down in music.
Teacher: Besides the two ways of playing from 1 to 10 and counting backwards from 10 to 1, which number can I start with? You can play freely, but please remember that the requirement of this game is to start from any number in chronological order or countdown.
The child will go to the rest area to rest. The teacher summed it up.
5. Take the elevator downstairs and practice the countdown to 10-6.
(1) Play the courseware: Tell everyone a good news. Today is the anniversary of Amusement City 10, and a prize quiz is being held on the 6th floor. Welcome everyone to participate actively.
Teacher: Children, there is a quiz on the sixth floor! Let's take the elevator to the sixth floor quickly. Hang in there, everybody. The elevator is descending (countdown 10 ~ 6).
(2) Expanding experience: the application of ordinal number and reciprocal in life.
Teacher: Sit down, children. The test will begin.
Question: When should ordinal numbers or reciprocal numbers be used in life?
The child discusses before answering, and the teacher guides the child to think. If you answer correctly, you can get a prize.
Question: When do you need ordinal numbers or countdown in your life? Go home and look for it with your parents.
6. Take the elevator downstairs and practice the countdown from 6 to 1.
Teacher: It's getting late. It's time for us to take the elevator downstairs and go home (from 6 to 1).
5. Design the license plate number, and practice the sequence number or countdown one step from any number within 10.
Teacher: There are two cars here, neither of which has a license plate number. Ask children to help design the license plate number. The number must be 5 digits in the sequence or 5 digits at the bottom. What number do you want to design? Think for yourself first, or you can discuss with the children next to you.
(a) distribution of operating materials, children's pattern license plate number.
(2) Let the children tell their companions the license plate number they designed.
(3) End the activity
Teacher: The license plate number is designed. Let's drive home together.
The children imitated music and drove out of the activity room.
Activity reflection:
After the activity, some children consciously lined up, and asked one person to be the monitor to count in order, and some counted in the form of driving a train, which can show that children are interested in exploring, so our teacher should let go and let the children play and explore by themselves. After all, learning can't be completed only through one or two group activities.
Encyclopedia: reciprocal is a mathematical term, and the pinyin is dàoshù. Mathematically, it means that the product of a number x multiplied by it is 1, which is recorded as 1/x, and the process is "multiplication inverse". All numbers except 0 have reciprocal, and the numerator and denominator, in turn, are the reciprocal of 1, and 0 has no reciprocal.
Kindergarten big class countdown teaching plan 2 goal
1, learn to count backwards and forwards, learn to count backwards and forwards.
2. Perceive the law of reciprocal and ordinal number in the game and develop children's thinking development.
3. Emotionally, children can take the initiative to learn in a happy mood, experience the happiness of mathematics activities and feel the fun of collective activities.
Focus of activities
Understand the inherent law of ordinal number and reciprocal.
Activity difficulty
Learn to count backwards and backwards.
Activities to be prepared
2 sets of 1, 1—1magnetic digital cards and1directional arrows.
2. Frog 10, some lotus leaves.
3. Two pictures of the same locomotive (difference: different license plates)
4. High-rise model 1, 1— 10, and paste number 1.
5, "Driving a Train" music
Activity process
First, the beginning part:
(1) Teachers introduce themselves to express their joy in meeting new friends.
(2) Teachers introduce frogs and visit frogs' new buildings by talking to attract children's attention and enthusiasm for participating in activities.
(3) Teachers and children play games to pave the way for knowledge.
1. Perceive the relationship greater than 1 less than 1 by clapping games.
2. Digital perception is greater than 1 less than 1. Relationship: For example, how much is 1 more than 2? 1 What is the number less than 9?
Second, the basic part:
(1) Teachers guide children to count off, so that children can initially perceive the inherent law of ordinal number and reciprocal, and make a summary: we arrange the last number in order from small to large, which is more than the previous number 1. The number of rows arranged in this way is called ordinal number. Arranged from a large number to a decimal number, the latter number is L less than the previous number, so the number of rows arranged in this way is called reciprocal.
(2) Teachers guide children to observe and perceive from four directions: up, down, left and right. With the change of orientation, the order of numbers will also change.
(3) review and consolidate:
1. The teacher introduces frogs in a magical tone, finds out the differences between frogs, guides children to find that some frogs have no numbers on their chests, and inspires children to fill in numbers according to the rules.
2. The frog wants to play hide-and-seek with the children, and guide the children to practice counting, counting backwards from any number.
3. Teachers take a small train to visit the frog's new building, introduce the small train, guide children to observe the changing direction of license plate numbers, and once again perceive that the order of numbers will change due to the change of orientation, and guide children to take the train according to the arrangement law of license plates and report the numbers, so as to experience and perceive the order and countdown in the form of participation.
4. By observing the building, guide the children to practice the number of continuous connections and the number of backward connections. For example, if * * who lives on the fifth floor wants to visit * * on the 1 floor, which floor should he take? ……
5. The teacher guides the children to participate in the game by blessing the frog to move to a new home, and practices the sequential counting and countdown again, such as: "Clap your hands, 123, then count ……" (456), "Clap your hands, 987, then count …" (654).
Third, the conclusion part.
Expand children's thinking, guide children to recall where there are ordinal numbers and reciprocal numbers in life, and enrich children's life experience.
Activity expansion
Ask the children to go home and seek and consult information with their parents. What other uses do ordinal numbers and reciprocal numbers have? Come and share it again next week.
Countdown Teaching Plan 3 for Kindergarten Large Class Activity Objectives:
1, knowledge goal: inspire children to find the order of numbers within 10 through their own attempts and know what ordinal numbers and reciprocal numbers are.
2. Ability goal: Perceive the positive-negative relationship between ordinal number increasing by 65,438+0 and reciprocal number decreasing by 65,438+0, understand different counting methods, and experience the reversibility and transitivity of a natural sequence within 65,438+00.
3. Emotional goal: cultivate children's spirit of trying and develop children's agility and logic of thinking; Stimulate children's interest in learning, experience the happiness of mathematics activities and feel the fun of group activities.
4. Develop visual perception and judgment.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Focus of activities:
Learn to understand the inherent laws of ordinal numbers and reciprocal numbers.
Activity difficulty:
Reversibility and transitivity between sensory sequences.
Activity preparation:
1, teaching AIDS: teaching wall chart "Squirrel Picking Pine Nuts", animal pictures, some pictures of mushroom house, digital card of 1- 10, projector, TV.
2. Learning tools: one set of point cards and one set of number cards from 1 to 10.
Activity flow:
I. Organizing teaching
The game "clap your hands" (to attract children's attention and consolidate old knowledge)
1, clap your hands as much as you said. For example, I say X, kid: I shoot X. (being photographed)
Second, stimulate the introduction of interest, arouse children's interest
1. Today, the teacher brought a child to the children. Let's see who it is. Question: Who is in the photo? (Little squirrel) What is it going to do? Counting: How many steps are there from the home of the little squirrel to the pine tree on the top of the mountain? (Grade 10)
Activity: I'll pick pine cones.
(How to learn ordinal numbers and reciprocal numbers)
1, squirrel, this is the first time to pick pinecones on the mountain alone. Oh, I'm afraid I'll get lost So, he thought of a good way, that is, mark the steps with numbers, step on these numbers up the mountain, and then step on the numbers down the mountain when he comes back. Now, would you please ask the children to mark the numbers for him?
Individual children come forward to try. Put the digital card on the corresponding step. (1-2-3-4-5-6-7-8-9-10, just10 steps up the hill. )
2. When I get to the mountain, how can I get down if I go back the same way? ( 10-9-8-7-6-5-4-3-2- 1)
Question: What's the difference between the figures found by the children when they come back and those found when they go? (Inspire children to feel that when we reach the top of the mountain, we start counting from a small number, and the following numbers are all 1 greater than the previous number, while when we go down the mountain, we start counting from a big number, and the following numbers are all 1 less than the previous number. ) The sensing range is from 1 to 10, followed by numbers greater than 1, and the countdown is less than 65438.
Teacher's summary: Establish the correct concepts of ordinal number and reciprocal number, and arrange them in descending order. The latter number is more than the former number 1, so the arranged number is called ordinal number. (The number of children's songs) is arranged in descending order, and the last number is less than the previous number 1, so the number arranged in this way is called reciprocal. (Children singing)
Fourth, hands-on operation: send small animals home
1. Show me the test question: Building a new house for small animals.
Little squirrel has many friends, including lamb, white rabbit, deer, pig and little squirrel. They are also invited to play at home. They love the squirrel's home, and they all want to have a house like this. They live on the mountain, and they can often play together in the future, so they want to ask their children to help them build their houses, okay? There are requirements for building a house. Every small animal's home should be separated by a certain distance, just 10 step, so that everyone can move up and down.
(1) The teacher demonstrated how to build a house for a lamb by reciprocal method, just 10 steps away from the squirrel's house. Build a house there (please ask the children to come up and put pictures of the house and the lamb on the wall chart)
(2) Children use the same method to help other small animals build new houses in turn. For example, there are 10 steps from lamb's house to rabbit's house, 10 steps from rabbit's house to deer's house, and 10 steps from deer's house to piglet's house. (Let children further master the method of countdown. )
2, the second attempt: true and false "house"
There are many identical houses on the mountain. This time, Coke broke Big Wolf. He thought of a good way to catch small animals. What can he do? That is to tear up all the photos on their houses and build many identical houses, making them all traps. Big Big Wolf wanted to keep the animals from finding their homes, but they fell into his trap. Will small animals be fooled? What good ideas does the child have? Inspire children to teach small animals to count, arrange them in chronological order and countdown order, and find the "real" house. Try to find a home for the small animals yourself.
Step 3 do it yourself
Arrange the counting cards and counting cards within 10 in chronological order and reciprocal order respectively.
Fifth, thinking expansion.
Where can I use ordinal numbers and reciprocal numbers in my life?
Elevator, traffic lights, rocket launch, countdown ... by watching multimedia demonstrations, feel the application of ordinal number and countdown in life.
Activity expansion:
The game "Climbing the stairs". Children are free to go up and down the stairs. When they go upstairs, they count 1, 2- 10, and when they go downstairs, they count 10, 9- 1 in order to consolidate their understanding of what is ordinal number and what is reciprocal.
Countdown teaching plan for kindergarten large class 4 I. Activity objectives
1, master the ordinal number and reciprocal of 1- 10.
2. When the ordinal number is known, it increases one by one, and it decreases one by one when counting down.
3, like math activities, willing to participate in various arithmetic games, and cultivate rebellious thinking.
4. Develop visual perception and judgment.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Second, the activity preparation
Puppy crossing map 1 piece, 1-5 digital cards, various square building blocks, several flower pieces and 6 operation cards.
Third, the activity process
1, drive the train-review the ordinal number and reciprocal within 5.
Teacher: "Today, we are going to visit the dog's home. Let's take the train together! " "Play oral counting games while driving, such as showing the number plate 5, the number of teachers 12345, and the number of children1;
2. Puppy crossing the bridge
(1) Enjoy the Rainbow Bridge
"The puppy wants to bring gifts to the elephant house to entertain the children, but there is a big river in the middle and he wants to cross a colorful Gao Qiao. You see, how did the uncle worker design this bridge? " (Children discuss freely and the teacher summarizes)
This bridge is made up of many small squares. The middle of the bridge is high and the sides are low. The steps of the upper bridge and the lower bridge are 10.
Teacher: "The first step of the bridge is 1 brick, the second step is 2 bricks, and the tenth step is 10 brick." (1 can mean that there are 1 bricks, or the first step, 2 can mean that there are two bricks, or the second step ...)
(2) counting step
Teacher: "The puppy started to cross the bridge. Let's count them together. How many steps did it take on the bridge and how many steps did it take off the bridge? "
Children: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, Shangqiao 10.
When getting off the bridge 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 10.
Teacher: When counting, you can count backwards, or you can count backwards, that is, count backwards from larger numbers to smaller numbers.
Teacher: When the puppy came home, it had already walked the fifth step. Will the children help him get on and off the bridge? Put the puppy on another step and let the child help it go home and practice counting. )
3, children's operation
(1) number: an eight-digit telephone number, which requires children to fill in the spare four digits. You can fill in the numbers sequentially or count backwards. (When you fill it backwards, you must fill it backwards according to the four digits provided by the teacher. )
(2) Counting flower pieces: Children put out small flower pieces from 1 level, one by one, and the number of sides is increased until 10. Then count down, pick one at a time, count again and practice counting down. (10 person)
(3) Take Gao Qiao: Cooperate to build colorful bridges, and take the number of sides. (4 persons)
Fourth, the game "Train Whoops"
Countdown Teaching Plan 5 Activity Goal of Kindergarten Large Class
Interested in the application of ordinal number and reciprocal in life, and understand the role of ordinal number and reciprocal in life.
Starting from any number within 10, the process and result of operation activities are expressed in words, forming reversible thinking.
By comparing the different laws of 1- 10, we can perceive the arithmetic relationship of natural sequence, and know that the last number in chronological order is more than the previous number 1, and the last number in reciprocal order is less than the previous number 1.
Activities to be prepared
Experience preparation: children count the numbers within 10 and compare the numbers.
Courseware preparation: "Carton staircase" picture; "Shopping" pictures; "Go to the station" picture; "Take the wrong bus" picture.
Activity process
Show the picture "carton stairs" to guide children to perceive the arithmetic relationship between the numbers 1- 10, 1 more, 1 less.
Qiqi Panda is going to his friend's house to play, but his friend lives on a high platform. Here are some cartons. Do you have any good ideas?
The cartons are all packed. What do you think they look like? (stairs)
-How many cartons are used on each floor of the stairs? ( 1- 10)
-How many cartons are there between every two adjacent steps? ( 1)
-So what's the difference between every two adjacent numbers? (No.1)
Summary: the number 1- 10, and the difference between every two adjacent numbers is 1, for example, 1 is less than 2, and 2 is greater than1; 2 is smaller than 3 1, and 3 is larger than 21; ..... (and so on).
Show the picture "shopping" and guide the children to learn the ordinal number within 10.
Kiki and his friends are going for an outing. They need to go to the store to buy something first. How many steps are there from their friend's house to the shop? (Grade 10)
-Kiki wants to go upstairs in what numerical order? ( 1、2、3、4、5、6、7、8、9、 10)
-What changes have been made to the figures after the first step? (getting bigger and bigger)
-What's the number behind? (large 1)
Summary: Numbers arranged in the order of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 are called ordinal numbers, and the ordinal numbers are arranged from small to large, and the latter number is higher than the previous number 1 large 1.
Show the picture "Go to the station" and guide the children to learn the countdown within 10.
Kiki and his friends are going to the station after shopping for the outing. How many steps are there from the shop to the station? (Grade 10)
-What numerical order does Qiqi want to go downstairs? ( 10、9、8、7、6、5、4、3、2、 1)
-What changes have been made to the figures after the first step? (getting smaller and smaller)
-How much is the last number smaller than the previous one? (small 1)
Summary: Numbers arranged in the order of 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 are called reciprocal, and the reciprocal is arranged in descending order, and the last number is smaller than the previous number 1.
Show the picture "Take the wrong bus" to guide children to further consolidate the ordinal number and reciprocal, and master the ordinal number and reciprocal of any number within 10.
-Here comes the bus. Qiqi and his friends got on the bus, but they mixed up their tickets and got on the wrong bus. Listen carefully to the request and help them get back to the right car.
-Qiqi/Miaomiao/Mimi/Fu Xiao is going to car No.8/No.4/No.2/No.7. Which cars does it pass? Is this ordinal or reciprocal?
Activity expansion
Family education
Let the children go home and observe carefully to see what is in chronological order in life. What are the reciprocal things? Further feel the role of ordinal number and reciprocal in life.
