The design intention of kindergarten mathematics 5 subtraction teaching plan 1;
Mathematics is an abstract logic subject. When organizing teaching, children often feel that their interest is not high and their desire to learn actively is not strong. It is clearly pointed out in the syllabus that games are children's basic activities. In order to create a space for children to actively explore and learn, I created a game situation space for children, so that children can actively gain the experience of "adding and subtracting 5" in a series of operations and game activities such as "arranging supermarkets" and "buying activities".
Activity objectives:
1, learn the addition and subtraction of 5 to further understand the relationship between addition exchange and addition and subtraction.
2, can use a relatively complete language to write application questions, can correctly write addition and subtraction formulas, and maintain a correct writing posture.
3. Being able to play games with peers and experience the fun of cooperating to complete tasks.
Activity preparation:
1, tell children to set up Beibei toy supermarket in advance, so that children and teachers can prepare various toys together.
2. Create Beibei toy supermarket with children (divided into 4 pieces, with different sticky notes of the same color for each group of children), 40 toys with different numbers (dots), and 5 toy boxes (with the number 5 on them) for each group.
3.40 record cards for children to record (Tian Zige).
Everyone has an envelope with five hard banknotes.
5. Two large exhibition boards for teachers (Tian Zige).
6.20 foam pads.
7. Divide the children into groups of 5 people, and each group of children will stick different colored post-it notes.
Activity flow:
First of all, please arrange Beibei toy supermarket with children and teachers. Stimulate children's desire to clean up and tidy up.
Teacher: "This morning, the children brought many toys with price tags. Now let's decorate them together, shall we? "
Second, guide children to find the addition of 5 and ask them to record the formula.
Kindergarten Mathematics 5 Subtraction Teaching Plan 2 Purpose:
1, learn the subtraction of 5, and learn four groups of subtraction to calculate 5 correctly.
2. Children understand the calculation process of addition through operation and realize that it is the simplest method to calculate the subtraction of 5 with "the composition of numbers".
3. Cultivate children to actively participate in mathematics activities, gain successful experience and enhance self-confidence.
4. Develop children's logical thinking ability.
5. Stimulate children's interest in learning subtraction.
Focus of activities:
Learn the subtraction of 5. Difficulties: master the subtraction of 5 in the operation.
Reflection: Children know that 1 object and 4 objects add up to 5 objects, and we all know that 1 object is taken from 5 objects, but it is difficult for children to understand "5- 1=4", so the focus of this activity is to master the subtraction of 5 by operating children.
Activity preparation:
There are several composition formulas of 5, several operation formulas within 5, a background picture, a digital operation card of 1-5 and an operation card (five squirrels, five butterflies, five birds and five ducklings).
Reflection: children can't understand it and are not interested in abstract subtraction operations such as "5-2=3". However, if some physical objects are put into nature, children can subtract with appearances, so they have prepared the above teaching AIDS.
Activity flow:
One: the beginning part
Orff's music "Trains Fly Fast" The children "drove the train" into the fields.
Reflection: skillfully combine songs with mathematical knowledge to improve children's interest.
Second, the basic part
1, composition review of the game "Driving a Train" 5.
Now the teacher will invite children to play the game of "driving the train". Children who get the correct answer in the game can start training with the teacher.
"Train" game-the teacher "Hey, hey, what time does our train leave" (show the composition of 5); The child "Hey, our train leaves at ××".
Ask some children who speak actively to come up and play "driving the train" (with music) Teacher: The train is leaving, please come up.
Play the game twice and let every child participate.
Reflection: Crusca Ya, a famous educator, said: "Games are an important form of learning, working and educating children." Mathematics education combined with games can help children get rid of the boring concept of abstract numbers, thus improving their interest in reviewing the five components. In the game of driving a train, the children actively participated in answering questions and finally got on the long train through their own efforts.
2. Show the background picture
1 Teacher: We drove the train to a meadow. There are beautiful trees and flowers on the grass. Look, children, how many little squirrels have come down from the big tree? What's the number of five little squirrels? (5) How many squirrels are there left? What is the number of a little squirrel? (1) Five little squirrels are gone. 1 little squirrel. How many squirrels are left? (4) What symbol is used to represent (1)? We use the formula: 5- 1 = 4.
The noisy sound on the grass attracted the beautiful flower fairy. Who do you think will come? (Teacher performs butterflies) Let's count how many butterflies have come to pick flowers. There are flowers there, too, and two butterflies fly away (the following process is the same as above)
3. After a while, the bird came to play the game. How many birds did the children see flying? How many birds flew away? (The following process is the same as above)
Guess who's here, children. (The teacher plays ducks) How many ducklings are coming to swim? After a while, several ducklings swam away. (The following programs are in the same context)
Reflection: For these abstract subtraction of 5, proper explanation and demonstration can help children overcome difficulties, guide their thinking, and enable them to acquire scientific and systematic knowledge and analytical reasoning methods. In the demonstration while explaining, it is easier for children to understand that "on the original basis, staying is reducing". Explain the operation repeatedly, and the focus of this activity is also solved here. The addition of objects and scenes is also easy to concentrate children's attention.
3. Show the operation data, the teacher explains the requirements, and the child explains the questions.
Reflection: During the explanation, I found that some children didn't understand subtraction at first, but gradually realized that "there were five balloons flying away from 1, how many are left now?" The problem contains the meaning of reduction, and subtraction is used for operation.
4. The game "Set off firecrackers"
Teacher: What do children like to play best during the Spring Festival? (Setting off firecrackers) Now the teacher and the children play a game of setting off firecrackers.
Fireworks game-play 1 (show the formula of subtraction of 5 or addition and subtraction within 4 just learned) The teacher said, "It's New Year, set off firecrackers, and firecrackers will ring a few times." When the teacher answered correctly, the children said "Bang" together. When the teacher answered incorrectly, the children said "Hey" together. Play 2 (invite several children up, with the first person as the fuse). Show the formula of addition of 5 or addition and subtraction within 4 that you just learned. The teacher said, "It's the New Year. Let off firecrackers. How many times will firecrackers ring?". The following children act as referees, and say "bang" when they get the correct answer. The children on the stage say "hey" when they answer wrong. (You can give your child another chance to correct it)
Reflection: Mathematical games are a powerful lever to shape children's cognitive structure, and the content of "setting off firecrackers" is completely in line with this teaching, which promotes the development of children's cognitive ability of subtraction of 5. Let children study in a relaxed and natural atmosphere and like math.
Third, the conclusion part.
The song game "New Year is really lively" ended the activity.
Kindergarten Mathematics 5 Subtraction Teaching Plan 3 Activity Objectives:
1. Understand the meaning of haircut.
2. Master the hairstyle of 5 and know "-".
3. Experience the fun of math games.
4. Cultivate children's ability to recognize numbers.
5. Let the children judge the quantity correctly.
Activity preparation:
"-"card, 1-5 digital card, small animal headdress
Each person has an operation card and a toy card.
Activity flow:
1. Review the decomposition of 5, and understand the relationship between quantity and quantity through clapping games.
Teacher: Let me ask you, little friend, how much can 5 be?
Child: Teacher Yu told you that 5 can be divided into 3 and 2.
2. Create a scene, put a digital card, and use the corresponding relationship between number and quantity to understand the meaning of haircut.
Teacher: It's a beautiful day today. Bear invited his good friend to his house. Bear prepared a lot of delicious food, five bones, five bundles of feelings, five carrots and five bugs. His good friends, dog, lamb, rabbit and chicken, were so happy when they came. They ate so delicious. Let's see how much they ate.
Teacher: The bear brought five carrots, which are represented by the number 5. The rabbit ate two carrots, which are indicated by the number 2. How many carrots are left? The remaining three are represented by the number 3, and 5-2=3.
Understand that cutting your hair means reducing the number after you lose it.
3. Play games and let children play small animals. Count the five kinds of food on the plate in front of you. How many did you eat? How many are left?
4. Subtraction calculation exercise. Children are free to work in pairs. Children in each group take five toys and guess. After the child B closes his eyes, the child's family takes some toys, and asks the child B to calculate how many toys the child A takes for a haircut, and mark the formula with a digital card.
Suggestion: In order to consolidate and master the haircut within 5 hours, the teacher can provide colorful toys for the children in the activity area after the activity, so as to stimulate the children's desire for operation and interest in participating in the activity.
Activity reflection:
The math activity "bear treat" introduces the story of Bear Treat, and takes children into the matching learning of numbers, points and objects in a gamification and life-oriented way. Because the teaching AIDS and learning tools were fully prepared before class, the class went smoothly. The children listened carefully, learned well and, of course, finished their homework well. The activity flow is like this. Combined with the arrival of two festivals, I released the protagonist "Little Bear" and told the children, "In order to celebrate the arrival of the festival, Little Bear invited his good friend to be a guest like Mrs. Mouse today (I have learned from the early reading of" Mrs. Mouse Treat "). Look! How many guests did Bear invite today? " Then I show these animals one by one. Let children learn to be heroic bears. Welcome friends. These are familiar animal friends, such as cats, dogs, chickens and monkeys. Children like them very much. Let the children count individually and collectively. Today, the bear invited several guests, and the children quickly said "six guests". Then I asked some children to come up and look for the number 6 card and the number 6 dot card.
Step two, invite guests to dinner. According to the food prepared by the bear for his friends, count it with your hands and mouth, for example: 1, 2, 3, 4. There are four bugs in all. Say, learn to express yourself in complete sentences, for example, the bear prepared two carrots for the rabbit, which can be represented by the number 2. Look for and find the corresponding digital card from a pile of digital cards, such as the number 2 or a point card with two points. Take it, find the corresponding card and put it in the place where the animals and food match. In the form of individual, collective and pairwise cooperation, let the children match the physical quantities with the numbers and points in the bear's treat scene, correct their mistakes, learn from each other and experience happiness with the help of their peers.
The third link is to let the children operate on the third page of the activity material "Mathematics". I remind and inspire some children with weak ability in time, and guide them while patrolling. The children's completion is very good.
"Mathematics comes from life and is applied to life." Children use what they have learned in gamification scenes and consolidate it to serve their lives. Mathematics knowledge is based on life experience, so that children can further develop on the basis of the original knowledge and experience (near the development zone), which is more in line with children's development law and learning characteristics. Teachers' teaching methods should emphasize "interest" to arouse children's interest. Life-oriented and game-oriented methods are more suitable for children, easy for children to accept, and stimulate children's interest in knowledge and desire for operation. At the same time, I also found that the ability of individual children is really weak, especially the newly arrived children. It is necessary to communicate with parents more so that children can adapt to learning as soon as possible.
Subtraction Teaching Plan 4 Kindergarten Mathematics Activity Goal 5:
Learn to say the meaning of subtraction in language and experience the meaning of "remainder"
Observe the arrangement of the patterns, and then draw according to the patterns.
Activity preparation:
Teaching aid: Three pictures with numbers and symbols on them.
Activity flow:
Group activities.
Show me the picture 1.
"These three photos tell the same thing. Take a closer look at who can make each picture clear in one sentence? " Let's start with the first picture. There are four bees on the flower. ) "Look at the second picture. Who will speak? ""How do you know if you are coming or leaving? " (Two bees fly away. ) "Let's connect the first picture with the second picture and think about what the third picture should say?" There are two bees left on the flower heart. "Let's talk about three pictures together."
Record with a formula and express the meaning of the picture.
1, "Who will use a formula to record this? Do you think he remembers correctly? "
2. "Who can tell me what each number and symbol in this formula in the picture means? Read the formula twice. "
Look at the subtraction formula of three pictures in group activities.
Feeling after teaching: Through the study of this lesson, let the children say the meaning of each picture in concise language, learn to say the meaning expressed by the subtraction formula in language, and experience the meaning of "Yu".
Subtraction teaching plan 5 activity goal of kindergarten mathematics 5;
1, learn the subtraction of 5, understand the quantitative relationship between each picture, and understand the meaning of "used up" and "left over".
2. Learn to express the meaning of subtraction formula in concise language.
3. Experience the fun of math activities.
Activity preparation:
PPT, each child has a set of digital operation cards, a mailbox with the number 1 ~ 4, and several "letters" with an addition formula problem within 5.
Activity flow:
1, play the game of "touching the ball" and review the composition of 5.
Teacher: Children, today the teacher will play a game of "touching the ball" with you.
Explain the rules of the game: the number of balls the child said and the number of balls the teacher said add up to five. For example, the teacher said, "How many balls does my ball touch?" The child replied, "Your 1 ball touched 4 balls". Children can answer in groups or practice alone.
2. Show PPT and learn the subtraction of 5.
(1) How many cups are there on the table? What is the number of babies? How much of this have you used？ What is the number of babies? How much is left?
(2) Teacher (showing the minus sign "-"): What does this symbol mean? (Guide children to discover the meaning of "minus sign". )
(3) The teacher answers the blackboard according to the children: 5- 1 = 4 (Read this formula together. )
(4) Teacher: What does this formula mean? Ask children and teachers to look at the picture and say the meaning of the formula, and put a formula on it.
3. Combine with life.
(1) There are five cups in the pig's house. There are three guests in the house. Piglet pours tea for the guests. How many empty cups are left now? Please use the formula.
(2) When the little monkey saw five bananas in the pigsty, he ate them happily. The pig looked at the bananas, and there were only two. How many bananas did the little monkey eat?
Activity expansion
Put the digital cards and symbols in the math area and take out the subtraction formula of 5.
Subtraction Teaching Plan 6 Kindergarten Mathematics Activity Goal 5
1, can add and subtract numbers within 5 with representation, and can express the operation process in language.
2. Develop thinking in images.
3. Cultivate children's ability to recognize numbers.
4. Let children learn simple math problems.
Important and difficult
1, key point: understand the meaning of addition and subtraction.
2. Difficulties: express the operation process in language.
Material and environmental creation
1, material: plastic animals, snowflakes and other items. 1-5 digital card. Picture card for addition, subtraction, multiplication, division and drawing. Sealed.
2. Environment creation: Place the above materials in the math area for children to manipulate, explore, review and consolidate activities.
Design concept
Oral addition and subtraction is the beginning for children to learn addition and subtraction, and the focus of the activity is to let children know the significance of addition and subtraction. In teaching, it is necessary to avoid making children form a wrong mindset, that is, having "total" in the topic means addition, and having "surplus" means subtraction. When designing, children can be exposed to different expressions, such as addition, one is to "combine" two partial numbers, and the other is to "add a few" on the basis of one partial number. Another example is subtraction, one is to remove a part from the total and find the remaining part, and the other is to find the reduced part by knowing the total and the remaining part. Help children to combine the psychological operation activities of combination or division with addition and subtraction with concrete image methods, so that children can really understand the significance of addition and subtraction.
Another purpose of this activity is to develop children's thinking in images. Because representation is the intermediary of the transition from concrete image thinking to abstract logical thinking, children have to manipulate and use representation to calculate addition and subtraction. Finally, the calculation of abstract numbers can be realized. Therefore, when designing, we should first let children accumulate rich representations, and then encourage children to use representations for operations by solving oral application problems. In addition, it is also an effective way to improve children's thinking level to let children express the calculation process in language. However, at the beginning, children will have some difficulties. In teaching, visual teaching AIDS can be presented appropriately to help children clear their minds.
Activity flow
Operating experience-> discussion and understanding-> review and consolidation
1, operation.
(1) physical operation. Let children use plastic animals, snowflakes and other items to add and subtract, and use the corresponding digital cards to represent the operation results. For example, how many rabbits are three white rabbits and two gray rabbits combined?
(2) Look at the picture and calculate. Let the children add and subtract according to the meaning of the picture. Let the children say the pictures first, and then calculate the results.
Note: The graphic meanings provided should have different expressions of addition and subtraction. Such as addition, some count how many fruits are in two plates. Some children are playing and some are coming.
2. discussion.
(1) Show visual teaching AIDS to help children understand the meaning of addition and subtraction.
(2) Teachers make up application questions orally, and children use images to calculate and tell the calculation process.
(3) Children orally compile application questions.
3. review.
Children use seals of animals, fruits, etc. to make picture cards of addition and subtraction. , and answer the addition and subtraction questions on the card made by your partner.
Activity reflection
"Addition within 5" is taught on the basis of students' understanding of numbers within 5 and their preliminary understanding of the meaning of addition. The standard holds that: "Because students' living backgrounds and thinking angles are different, the methods adopted must be diverse. Teachers should respect students' ideas, encourage students to think independently and advocate the diversification of calculation methods. " So according to the characteristics of students, I designed the following teaching links:
1, review Ask students to set up learning tools. Set three and five first, then divide the three into two piles and the five into two piles, and talk about how to divide them separately. Ask the students to recall the composition in 5 minutes and prepare the addition in 5 minutes.
2. Explore new knowledge. Use the dynamic pictures of multimedia courseware to attract students' attention. After asking the students to tell the meaning of the pictures, let them take out sticks instead of balloons and swing them. Let the students know that addition is needed to close the balloons on the clown's hands. When they speak, they use gestures to show that they can do it. They are eager to show in conversation that they can do it. At this time, let some students talk more and deepen their impressions. Then ask the students to list the addition formula and guide them to know the plus sign. After the formula is listed, ask the students to talk about what each number in the formula represents, so as to prepare for learning to solve problems. When calculating the results, ask the students how to calculate. Some students said to divide, to combine, and some students said to count. They don't emphasize a certain idea, but affirm each one and encourage students to have different methods. When adding a larger number in the future, students will choose the most convenient and appropriate method and leave room for thinking.
3. Practice in layers. First, let the students take three sticks in their left hand and two sticks in their right hand. Ask how many sticks are together, and experience that the combination of sticks with two hands is 3+2=5. After playing this game several times, let the students read p24 and "Do" and say the meaning expressed by the formula. For the third picture, some students will say the meaning of the formula from the words on the picture, and some will say the meaning of the formula from the paper crane on the table, and they will all be sure.
This lesson tries to embody the concept of "respecting students and paying attention to development". Through students' observation, independent exploration, operation and expression, students can feel and understand the generation and development of knowledge and taste the fun of discovering mathematics. At the same time, after teaching, the diversity and interest of sensory practice need to be improved.
Subtraction Teaching Plan 7 Kindergarten Mathematics Activity Design Background 5
Addition and subtraction within 5 is the basis of addition and subtraction within 10. It is difficult for students to learn from kindergarten, and it is difficult for most students to master it well. Therefore, I focus on the connection between the calculation of perceptual number and life, and experience the significance of addition and subtraction in specific situations and activities.
moving target

3. Display visual teaching AIDS
4. Guide children to dictate the addition and subtraction application problems of 5.
5. Play the game "Who is the fastest"
Step 6 write the formula
7. The teacher makes a summary
Teaching reflection
1, contact students' real life, and let students realize that addition and subtraction are around us.
Students' real life makes them realize that addition and subtraction are around us.
3. In order to make students do oral calculation correctly and quickly, they must also be trained through various forms of exercises. I actively advocate the diversification of algorithms and provide students with opportunities for mathematical communication, with the aim of promoting students' mathematical thinking activities and improving their mathematical thinking ability. Because of the diversity of algorithms, different students have different problem-solving strategies. They will use their own methods to solve problems and have a deep understanding of solving mathematical problems, thus gaining experience in learning mathematics. These algorithms are the results of students' thinking according to their own basic knowledge and life experience. Each different algorithm represents a sense of innovation, thus effectively training divergent thinking.
Subtraction Teaching Plan 8 Kindergarten Mathematics Activity Name 5
Mathematics Activities in Kindergarten Large Classes —— Subtraction within 5
moving target
1. Let children understand the meaning of subtraction and the meaning of subtraction by matching subtraction questions according to the meaning of the picture, and learn the fast oral calculation ability of subtraction questions within 5.
2. Cultivate children's abilities of observation, comparison, language expression and positive thinking.
Activities to be prepared
1. beverage card, bus arrival card, window opening card, and several subtraction cards within 5.
2. There is a mailbox with the number 1 ~ 4, which contains several "letters" with an addition formula within 5.
3. Everyone has a picture of an animal with a subtraction formula and some crayons for coloring.
Activity process
1. Look at the picture, match the formula questions and say what the formula questions mean.
(1) The teacher shows the drink card and the bus arrival card, and asks the children to use the pictures on the table to find the formula card for making friends.
1) Read the formula on the card you find.
2) Talk about the meaning of the pictures expressed in the formula questions.
Summary: We understand the meaning of the picture, find a formula to make friends with it, and know that we should remove a few cups of the original drinks and the people who got off the bus from the original passengers. When you want to calculate how much is left, you can use the subtraction formula to express and calculate the result.
3) Think about whether things around us about eating, using, playing and happening can also be expressed by 3- 1=2 or 5-2=3.
(2) Show the window card and let the children look at it carefully and think about it. What different subtraction formulas can be found in this picture to express the meaning of the picture?
Summary: Some pictures can only express one meaning, so you can only find a formula to be friends; Some pictures can express several meanings. You can find several different formulas and make friends with them. Look at the picture more carefully in the future and try to find out all the formulas that can make friends with it.
Play the game of delivering letters
(1) Show the game materials-4 mailboxes and many letters for children to observe, think and discuss the rules of the game.
(2) Let the children open four mailboxes in groups and check whether the "letter" is delivered correctly according to the rules of the game.
Computational coating
Show the problem card of subtraction formula within 5, calculate the problem of subtraction formula, and color it according to the answer. If the answer is 1, draw your favorite color. If the answer is not 1, you can't draw it.
Step 3: Make up the questions freely.
The teacher does not provide any conditions for compiling questions, so that children can compile questions completely according to their own life experience and knowledge. This is also a form of compiling questions that children like very much. At the same time, self-made application problems can arouse the appearance of addition and subtraction scenes in children's minds, and play the role of intermediary and bridge for children to master addition and subtraction operations from concrete to abstract, thus promoting the improvement of children's abstract ability.
