How to guide children to understand the purpose of the odd-even number lesson plan 1
1, by trying to calculate, children are required to recognize and distinguish the singular and even numbers within 10, and have the ability of preliminary judgment.
2. Cultivate children's hands-on and trying spirit and develop children's thinking flexibility.
Activities to be prepared
1, projector, slide show, tape recorder, toy motorcycle, etc.
2. Texturing teaching aid: from 1 to 10, there are five cards and five small disks (60 small disks each).
3. Each group has several notes from 1 to 10.
4. The child has a small red and yellow flower (one is odd and the other is even), a geometric pendant and a "magic paper".
Activity process
First, take children into the knowledge hall to stimulate their interest.
Teacher: Today, the teacher took the children to the Knowledge Palace to play bowling. In the knowledge palace, teachers will give children many gifts, but these gifts can only be obtained after children think hard. Do you want to go? Now, please ask the children to find their seats according to the figures on their chests and the numbers on the figures. If you find it, this number will be given to you as the first gift. (Children enter the activity room)
Second, let the children find the odd and even numbers within 10 by trying.
1, show slide 1. Children can perceive what is singular and what is even through observation.
Teacher: The children are very clever. They have found their seats. Now I want to test you. Please come to the front in a semicircle and line up from left to right. (Children check and read collectively) Well, that's good, but don't think these figures are simple. There are many secrets in it. Let's have a try today and find out the secret, shall we?
Now I'm going to invite children to watch a small movie. Let's take a closer look at what's on it and what's the difference between them on the line. (Slide 1: 6 fish, 5 shrimps)
(The children answered, and the teacher concluded: Like six fish can line up in pairs, the corresponding numbers are even; Like five shrimps, there is a single unpaired one in the end.
2. In the first attempt, each child put two small flowers and said how many red flowers and yellow flowers were put respectively, whether they were odd or even.
Teacher: The children already know what is singular and what is even. Now, please try to show the little red flowers and yellow flowers on your desk, and then tell your shoulders how many red flowers and yellow flowers there are, whether they are odd or even.
(children's operation, the teacher reminds children to think about how to put it, so as to see if it is odd or even)
3. In the second attempt, children are free to choose different mining methods and try to find out what odd and even numbers are in 10.
Teacher: The children are so clever that they can't even beat you in the puzzle of the Knowledge Palace. Would you like to try again and find out which of the ten numbers of 10 are singular and which are even? The teacher has prepared a lot of materials for you, such as flannel, counting cards, discs, paper, pens and so on. Now, please try to find it yourself and see who can find the odd and even numbers within 10 first.
Let a group of children put a CD in front of them, and then let them answer how they found it. Why, 1, 3,5,7,9 is singular, and 2,4,6,8, 10 is even.
Third, deepen the difficulty of trying and quickly distinguish between single and double numbers within 10.
1. Show slide 2. Please show the children what's on it. How many/much? Is it singular or even?
2. What do strange children look for in themselves or around them? How many/much? Is it singular or even?
3. Magic: Please fill in odd numbers (or even numbers) on the "magic paper" with colored pens as required.
Teacher: It's amazing that children have discovered the secrets of odd and even numbers. Now let's do a magic trick together, shall we? It has been changed, so I'll give it to you as a second gift. Now listen to the teacher tell you how to change it. ...
Fourth, drive a train game and walk out of the knowledge hall.
Teacher: Today, we found the secrets of odd and even numbers in the knowledge palace. It's time for us to go home by train. Teacher Ni and Teacher Lu are locomotives. Please look at the numbers on the chest. It's time for us to start ... (play music and drive the train out of the activity room)
How to guide children to know odd and even teaching plans II? First of all, talk about textbooks.
Teaching material analysis: This activity uses odd and even numbers in the first volume of the provincial textbook. The goal of mathematics education is to "feel the quantitative relationship of things from life and games, and experience the importance and interest of mathematics." Under the guidance of this spirit, I conceived this math activity. In the second class, there will be a series of games throughout the activity, so that children can enjoy learning while playing.
Talking about objectives: According to the age characteristics and actual cognitive situation of large classes, the teaching objectives are set as follows.
1. Stimulate children's interest in odd and even numbers and actively participate in math activities.
2. Through the creation of situational and gamification teaching, children can understand and distinguish odd numbers and even numbers within 10 in their operations.
Emphasis and difficulty: the focus of the activity is to stimulate children's interest in even and odd numbers. The difficulty is to understand and distinguish between odd numbers and even numbers within ten.
Activity preparation: animal cards and train tickets for 3 rabbits, 4 puppies, 5 kittens and 6 goats.
Second, oral teaching methods
Interest is the best teacher, and games are activities that every child is interested in. In order to let children master boring mathematical concepts easily and happily, I used the method of games to attract children's interest. As Dewey said, the game is like a layer of "sugar coating", which makes children swallow the "bitter medicine" that was originally difficult to swallow under the temptation of "sugar coating". Let children actively explore and discover in the game situation and gain experience in their own way. Really reflect the child's dominant position in the activity. Teachers, on the other hand, run the game through the whole activity with full emotions and timely guidance, and further deepen and consolidate the distinction between single and double numbers and master the ordering law of single and double numbers through the game from easy to difficult. Let you experience the happiness of success in the process of breaking through difficulties. This kind of teaching also conforms to the concept of "teachers should be supporters, collaborators and guides of learning" in the syllabus. In addition, I also use the observation operation method and appreciation incentive method to guide children to find and solve problems in the game, establish their self-confidence, and make this activity scientific, interesting and harmonious.
Third, theoretical study.
According to the spirit of the outline, mathematics education should "guide children to construct a preliminary concept of numbers and learn to solve some simple problems in life and games with simple mathematical methods". Children in large classes are in the late preschool period, and their learning ability and game level have been greatly improved. Therefore, in a series of step-by-step and challenging games, children are promoted to have a more thorough understanding of even and odd numbers and related concepts. Rich games promote the interaction between students and teachers, which not only embodies the concept of "children's development-oriented", but also helps to form the interaction between teachers and students of "cooperative inquiry".
Fourth, talk about teaching procedures.
In order to fully mobilize the children's various senses to participate in the activity, I organized this activity in a way from easy to difficult:
First, create a situation and perceive "single" and "double"
There will be animal parties in the forest, and teachers and children will participate, but the small animals will test the children. What "bachelors" do we have? What are the "double"?
(In the dialogue, the children said that they have one mouth and two eyes. The teacher concluded that there is only one mouth and one nose, which is called "single", and two pairs of shoes, hands and eyes are called "double". )
Second, attend animal parties.
1. small animal waltz
Story situation: Three rabbits, four puppies, five kittens and six goats came today. They will waltz together. Help them find a partner!
Children operate animal cards and pull them together in pairs.
Teacher: What did you find?
Young children: some small animals have one left and no companion; All the animals have found partners.
Teacher: Which small animals have only one without a partner? How many of these little animals are there?
Children: rabbits (3), kittens (5)
Teacher: Which small animals have companions? How many of these little animals are there?
Children: puppies (4) and goats (6)
The teacher summed up: two people look for friends, and in the end there is only one left, and there is no single friend. This number is called singular; Two people look for friends, and finally they both have friends, and nothing. Such numbers are called even numbers.
Now, let's play a game of "double avoidance", shall we
Third, consolidate the odd and even numbers-the game "hold the double, hide the single"
Rules of the game: children should teach according to what they are taught.
The teacher reads odd or even numbers. If teachers read odd numbers, they will bury their heads in their knees. If teachers read even numbers, they will hold their arms with both hands.
Fourth, the end.
The children are great. The teacher likes you clever children very much. The teacher will reward each child with a train ticket. The teacher will take you to travel by train later. Children will wear train tickets on their chests and carefully look at whether your tickets are odd or even. If you get on the wrong train, the ticket inspector will kick you out, so you can't travel with the children. Everyone is ready for the train to enter the station.
Children summarize the sorting rules of single and double numbers through personal operation.
Children consolidate single and even numbers in the game of "holding double hidden orders".
End session: The teacher will reward each child with a train ticket. The teacher will take you to travel by train later. Children will wear train tickets on their chests and carefully look at whether your tickets are odd or even. Odd trains will go to odd trains and even trains will go to even trains. This mathematical activity begins with the form of a game and ends with the form of a game. The whole activity runs through a series of dynamic and static games, allowing children to master even and odd numbers in a relaxed and happy atmosphere. Rich and varied games make logical and abstract mathematical knowledge vivid, and make children more acceptable and like learning.
How to guide children to know the activity goal of odd-even number teaching plan 3;
1. Children can identify and distinguish odd numbers and even numbers within 10 by trying operations.
2. Let children explore and understand odd and even numbers freely through games, and develop the flexibility of children's thinking.
3. Cultivate children's practical ability and spirit of trying, and feel the fun of communication between peers.
4, preliminary training observation, comparison and reaction ability.
5. Develop children's logical thinking ability.
Activity preparation:
Some toys; Several large number cards (one for each child); A Chinese phrase card with even and odd numbers; An old wolf headdress; Driving train music.
Activity flow:
First, import-the game "counting toys"
The teacher knows that children like playing with toys very much. Today, the teacher asked the children to grab a handful of toys and count how many toys there are. How did you know? (one number at a time)
Second, explore odd and even numbers-the game "find friends"
1. Now the teacher asks the children to help them find good friends, show the number 8 and match it with the same number of small black dots. The teacher demonstrated how to find friends, trying to make them good friends and see if they can both find good friends.
2. How many toys did you take just now? The children answered and the teacher showed different numbers, 10, 7, 5, 4, 9. ...
Let the children say: What did you find? Can find good friends; Can't find a good friend)
(1) I took six toys and divided them both.
(2) I took seven toys, and two got one.
(3) Summary: Digital cards that can find good friends have a nice name. Do you know what it is called? (Even) Digital cards that can't all find good friends also have nice names. (Singular) Displays Chinese phrases. So which numbers are even? (2, 4, 6, 8, 10) Which numbers are singular? (1, 3, 5, 7, 9) Children repeat several times.
Third, consolidate even and odd numbers.
1, game "Hug"
Rules of the game: children read aloud or give odd or even numbers according to the teacher's meaning. If the teacher reads odd numbers, they hold their arms in both hands. If the teacher reads even numbers, the two children hug each other.
2. The game "What time is it, Wolf?"
(1) The teacher shows the wolf headdress and leads to the game "Lao Wolf, what time is it?" .
The teacher explained the rules of the game: Lao Lang said that odd-numbered children should lie prone on the table quickly, and Lao Lang said that even-numbered children should hold each other tightly, or Lao Lang will eat you.
(2) The first game: The teacher plays the wolf.
The second game: children play the old wolf.
3.End: After introducing your good friend, you can introduce it to the visiting teacher.
Fourth, the game of driving a train.
Teacher: The children are great. The teacher likes you clever children very much. The teacher will reward each child with a train ticket. The teacher will take you to travel by train later. Children will wear train tickets on their chests and carefully look at whether your tickets are odd or even, whether Mr. Zhu's train is odd or Mr. Tang's train is even. If you get on the wrong train, the ticket inspector will kick you out. We should get going.
Activity reflection:
In this activity, I used the textbook of the big class (knowing odd and even numbers) to let the children know that the numbers in 1- 10 are 1, 3, 5, 7, 9. Even numbers are 2, 4, 6, 8, 10. In the whole class, I used games such as "Hug Hug", "What time is it for Lao Lang" and "Start the train" to further distinguish odd numbers from even numbers, and at the same time, I also cultivated children's positive thinking and the ability of unity and cooperation. After the activity, I think the children are excited and happy about "What time is Lao Lang", especially when Lao Lang wants to eat them. Unconsciously, the child once again has a further understanding of the singular and even numbers, and the degree of mastery has been further improved, reaching the expected goal.
In this class, I personally feel that I can't speak even numbers well, so some children answer irrelevant questions in the process of asking questions. In one class, because there are many children, the children's interest is a little out of control when playing the "train" game, and they can't move around the teacher's wishes, so the discipline is a bit poor.
