Mathematics teaching plan for kindergarten large class: ordinal number and reciprocal 1 activity target;
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, the numerator and denominator are in opposite phases, and the two products are the reciprocal of 1, and 0 has no reciprocal.
Mathematics teaching plan for kindergarten large class: ordinal number and penultimate activity 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. Relationship between number perception of 1 and number perception of 1: For example, what is the number of1greater than 2? From: big; 1 What is the number of "Kao Ba" 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.
