Lecture notes on mathematics in large classes

As a teacher, you have to write a speech, which can correct the shortcomings of the lecture well. So what kind of speech is good? The following are three drafts of mathematics handouts for large classes, which I compiled for reference only. Welcome to reading.

The teaching goal of 1 in the draft of large class mathematics handout;

1. Cultivate children's abilities of observation, thinking and calculation through independent exploration and learning.

2. Learn to say the corresponding answers according to the points on the two dice surfaces, and put the pieces one by one.

3. Develop the ability to analyze problems, and let children realize the relationship between numbers and chess through game activities.

4. Mention children's sense of competition through their operation, exploration and personal attempts.

Teaching preparation:

There are two big dice, a five-pointed star, various game of chess and a small dice.

Teaching process:

First, look at the dice.

1. Look what the teacher has in his hand. (Dice) Where have you seen it?

2. Let's see how many faces the dice consist of. Are the points on each surface the same? (one for each person)

Second, play dice.

1, the teacher took out a big dice and threw it gently on the ground. Please show the children what time it is. what do you think? You should look at the top of the dice.

The teacher gently threw two big dice on the ground together. Please show the children what time it is. Count the points on two dice together.

3. The teacher demonstrates how to write compound sentences and tells the children how much they add up to. 4+5=9

4. To understand the concept of composition, please ask one child to roll the dice like a teacher, and two children will come up to write the composition. Everyone will check whether his writing is correct, and if it is correct, a five-pointed star will be awarded.

5, free combination, divided into four groups of cooperative dice and record synthesis, the teacher tour guidance. When finished, put it on the blackboard and let all the children check whether the writing is correct. Use the five-pointed star as encouragement.

Third, play chess.

1. Today we learned two dice to count, which was really great. Each group also won a five-pointed star, which won the honor for the group. Shall we all play chess in this special way now?

Think about the advantages of playing chess in this special way. Chess pieces can be made faster, you can play more chess after class and learn to count.

3. Let's talk about the rules of the game first: in order. When the number is 6, you can throw it once and play it again. Whoever reaches the finish line first wins and gets a star.

4, children's games, cooperation and mutual assistance, teachers give some guidance.

5. End.

Lecture Notes on Mathematics for Large Classes 2 I. Design Intention

New > requires children to "perceive the quantitative relationship of things from life and games", and also pay attention to children's ability to explore, operate, communicate, solve problems and cooperate. Children learn the composition of 6 on the basis of knowing the composition of 5. Through learning, children can initially understand the relationship between whole and part, part and whole, lay a foundation for learning addition and subtraction, further deepen their understanding of logarithmic concepts, and cultivate their

Ability to observe, compare and calculate, thus promoting the development of mathematical thinking quality.

Second, talk about teaching materials.

(1) According to the "Guidelines for Kindergarten Education" and teaching materials, and in view of the age characteristics of children in large classes, I have determined the following teaching objectives:

1, learn the composition of the number 5 and know that the sum of the two parts is "6".

2. In the operation activities, constantly explore various divisor methods, know how to exchange the positions of two partial numbers and keep the total number unchanged.

I determined the focus of teaching: learning the composition of 6, knowing that 6 is divided into two parts and there are five ways to divide it. Teaching difficulty: the order of dividing and combining perceptual numbers.

(2) In order to complete this activity, I made the following preparations.

Some pictures of chickens and bugs; Draw a piece of homework paper with arithmetic problems for everyone; Some pencils, erasers and digital cards.

Third, oral teaching methods

One of the most prominent features of modern teaching methods is to emphasize the comprehensive application of various teaching methods and pursue the optimization of the overall effect. According to the content and goal of this activity and the actual situation of students and teachers, I adopted demonstration method, operation method, practice method and game method.

The thinking characteristic of large class children is that the seeds of abstract thinking have begun to appear. Their knowledge and understanding of the composition of numbers cannot be instilled by adults, but must be carried out through their own observation and operation activities. Piaget also said: "Mathematics begins with the function of objects". It shows that this operation method has the advantages of practicality, initiative and discovery. Every child's psychological development potential is different. Teaching practice shows that children will have "not enough to eat" and "not enough to eat" in the process of learning mathematics. Therefore, in the last link of teaching, I let the children practice by means of activities, so as to experience the joy of success.

Fourth, the methods of speaking and learning

According to the characteristics of teaching materials, I inspire and guide children to compare in observation and learn independently in operation, so that children can truly become the masters of learning.

On the combination of vision, hearing and motion perception, review the composition within 5 minutes. In the operation, let the children freely explore the division of six chickens and summarize them, so that the composition experience gained by the children is more clear and systematic. After that, in group activities, the children practiced and achieved the teaching goal well. Finally, let the children find a 6-year-old friend in a pleasant game atmosphere, and truly realize "learning by playing" and "learning by playing".

Fifth, talk about the teaching process.

(1) Review Composition 5) The teacher asked the children to play the game of touch ball to stimulate their interest in learning. )

Teacher: How many balls did my 1 ball touch? How many balls did my three balls touch? ) Yang: Your 1 ball touches 4 balls ... (Let the children review the composition of 5 while walking, mobilize their visual, auditory and motor senses, improve the accuracy and sensitivity of their multi-sensory perception, and lay the foundation for learning the composition of 6 later. )

(B), a preliminary understanding of the composition of "6"

1, Teacher: There are a group of chickens on the grass today. How many chickens are there?

A * * * has six chicks.

2. Teacher: Look, there are two houses. How can six chickens live in these two houses? Do something, children. How to divide it? Who will tell me? (Let the children help the chickens, which suddenly aroused their curiosity and actively carried out exploration activities. )

3, encourage children to actively use their brains to say the decomposition method, the teacher recorded the main points of the children on the blackboard one by one.

4. Teacher's summary: The total number of these two parts is "6".

5. Teacher: The chicks are very happy to live in the new house. "Gollum-"They are hungry. What can we do? Don't worry, mother hen has prepared delicious bugs for them! The teacher showed a picture with six bugs. )

6. Teacher: Now there is a chicken on the left and five chickens on the right. Who is willing to send them meals? The teacher laid out the rest of the pictures for the children to choose from and asked for one more. )

7. Teacher: If there were two chickens living on the left and four chickens living on the right, how would you divide the bugs?

8. Teacher: If there were three chickens living on the left and three chickens living on the right, how would you divide the bugs?

9. Teacher: If there were four chickens living on the left and two chickens living on the right, how would you divide the bugs? 10, Teacher: If there were five chickens on the left and 1 chicken on the right, how would you divide the bugs? (Guide the children to say where the two pictures are exchanged. )

1 1. Teacher's summary: The total number of exchange positions of two partial numbers is unchanged, and a component method is added.

(3), children's operation

1. In order to give children a chance to challenge, Teacher Zhang has prepared several difficult problems for you to see if you can challenge success.

2. Show the drawings. The decomposition method on this paper should be done by the children themselves. Please observe carefully and write the missing correct figures in the empty circle. Please do it in your seat immediately after the children finish it quickly. Please finish the composition of 6. )

Fourth, the game is over.

How to arouse children's enthusiasm again? Playing games is a child's nature. Playing games with plots and fun can keep children interested in activities for a long time. At the same time, combining games with learning mathematics is also in line with the principle of cultivating children to learn mathematics in many ways. So I designed a music game "password pairing" to let children find a friend whose numbers add up to 6 according to their digital cards. Let children be familiar with the composition of 6 in a pleasant atmosphere.

1, game "password pairing" rule: Teacher: Teacher Zhang got a password number today. Let's see what the teacher's password is. (Number 5) Teacher: The password to open this box must be 6 before it can be opened. I'm looking for my good friend. The combination password is 6. What is the other password I am looking for? (No.1)

2. Children's Games: Please hold the digital card in the desk in your hand. Let the children observe what their password is. What is the other password you are looking for?

Teacher: Make sure you have the right number. The password in your hand and the password you are looking for add up to six before you can open the box.

3. Children's game is over: play music and children sing hand in hand.

Lecture notes on mathematics in large classes 3 I. Talking about teaching materials

Around the age of 5, children gradually abstract the initial concept of number and can think logically about the relationship between number and number. Learning the composition of numbers is not only helpful for children to perceive and understand the quantitative relationship contained in the composition, but also the basis for understanding addition and subtraction operations and promoting the development of children's thinking ability. "Wukong parting peaches" is the fourth theme of mathematics activities in the big classroom. Its initial goal is to learn the composition of less than 4, explore the basic laws of composition, understand the meaning of addition and subtraction, and write the formula of addition and subtraction of 4 according to the composition law of numbers. We comprehensively consider the development level of children and the spirit in the Guide to Learning and Development for Children Aged 3-6. Understand the meaning of addition and subtraction in the original goal, and write the addition and subtraction formula of 4 according to the law of number synthesis as the content of the next activity. The content of this activity is mainly based on the Monkey King, a figure who is interested in Journey to the West. Focusing on the fun of Journey to the West, through hands-on operation and independent exploration, we can learn the composition of 4, understand the relationship between numbers and cultivate children's problem-solving ability.

Second, talk about children.

Children in large classes have initially acquired the ability to understand the reversibility, transitivity and relativity of quantity. After a period of study, they have basically understood the meaning of division and the relationship between quantity. But in the process of operation, they are sometimes disturbed by the specific characteristics of things. In this activity, through Wukong's peach splitting, help children realize the transformation of quantity from concrete to abstract, from individual to general.

Third, talk about the goal of the activity.

Kindergarten mathematics is a systematic and logical subject with its own characteristics and laws. The new syllabus puts forward that "mathematics education must let children feel the quantitative relationship of things from life and games and experience the importance and interest of mathematics"; Teachers should guide children to be interested in the phenomena of number, quantity, shape, time and space in the surrounding environment, construct a preliminary concept of number, and learn to solve some simple problems in life and games with simple mathematical methods. It can be seen that life and play have become the most basic principles of constructing mathematics courses. After having a certain understanding of the teaching materials and the learning situation of the children in this class, I made the goal of this activity:

1, learn the composition of numbers within 4 and explore the basic rules of composition.

2, can correctly record and express their own operation results, and dare to try different methods.

3. Experience the fun of solving problems.

In order to ensure the realization of this goal, I fully demonstrated the role of Wukong in teaching activities, and created Wukong test skills, Wukong fruit shop, monkey learning skills and other links to let children feel the number of things in the game.

Quantitative relationship, consolidate the knowledge learned.

Fourth, talk about the key points and difficulties.

The germination of abstract logical thinking appears in large class thinking. When we know things, we can not only perceive the characteristics of things, but also make preliminary induction and reasoning.

The key point of this activity: understand the composition within 4.

Difficulties: Explore the basic rules of composition.

Verb (abbreviation for verb) Speaking and teaching methods

This class belongs to the teaching of mathematical concepts, which is difficult for kindergarten children to understand. In order to help children master the key points of teaching and break through the difficulties, this lesson mainly adopts the following teaching methods:

1. Game method: Create vivid and concrete Wukong game situations, so that children can learn math knowledge in a pleasant situation. Through a series of game situations, review the composition within 3, explore the composition within 4, and consolidate the knowledge learned. We will use vivid and interesting storylines to show children's activities, stimulate their interest, mobilize their emotional input and activate their original knowledge and experience. On this basis, start thinking and consciously build knowledge.

2. Operation method: Encourage children to think independently, explore independently, cooperate and communicate in Wukong fruit shop and fight monsters. The current teaching needs to change children's traditional "accepting" learning style, and hands-on practice, independent exploration and cooperative communication have become important ways for children to learn mathematics. In teaching, let children think independently in specific operational activities, communicate with peers, experience the process of knowledge generation, and experience the fun of learning success.

In addition, I also respect children's individual differences in teaching. Because children's life background and knowledge level are different, teachers should pay attention to individual counseling in the process of participating in teaching activities.

Six, said the learning method

According to the new curriculum standards, children's learning style must be changed. This lesson adopts the methods of discovery, games and discussion, and strives to embody children's learning methods in specific situations, so that children can learn to solve problems by themselves and experience the success of exploration and the joy of learning. On the basis of hands-on, independent thinking and personalized learning, carry out peer communication and class communication activities, and let children establish learning methods through mutual help.

Seven, said the teaching preparation.

Material preparation: Wukong 1 headdress, theme song of Journey to the West, pictures of three fruits and price tag.

Signboards (respectively 1, 2, 3), bowling pins, several token cards, several baskets, cardboard record cards and several digital cards. It is mainly used to create game situations and explore the use of children in groups.

2. Children have basically mastered the composition of numbers within 3, which provides a knowledge base for children to learn the composition of numbers within 3.

Eight, said the teaching program

Mathematics is a rigorous discipline, and every knowledge point has certain rules. It is the core of this activity to let children discover the rules in exploration and apply them to their study life, so the activity mainly includes four links: scene introduction-Wukong relies on skills-Wukong fruit shop-monkey learns skills. The whole activity embodies the scientific part of the outline, "Curiosity and thirst for knowledge, from

(A) situational import, leading to the theme

Play the theme song of Journey to the West, lead to the animated character the Monkey King, stimulate children's interest in activities, and ask us for help through the Monkey King to lead to the next link.

(2) Wukong test skills, review the composition of numbers within 3.

Review the composition of numbers within 3 by watching the courseware, and review the original knowledge and experience in the game with the help of the situation of Wukong skill test, so as to lay the foundation for children to explore the composition of numbers within 4 freely.

(C) The composition of game inquiry 4 in Wukong Fruit Shop

In the game of Wukong Fruit Shop, every child will get a small basket and four token cards before entering the supermarket. Each child is required to buy only two kinds of fruits and must spend all the money. Let children freely explore the classification of 4, exchange game results, understand the composition of numbers within 4, and guide children to discover the laws of the increase, decrease and exchange of numbers through orderly arrangement.

This link is the focus and difficulty of this activity, and it is also the highlight of the teaching link. In this process, guide children to actively explore, bravely express their ideas, and strive to discover and summarize the laws, thus effectively breaking through the key and difficult points of this activity.

(d) Little monkey learning skills-consolidate the composition of the numbers in Exercise 4.

There are two small games designed in this ring. The first is a group battle against monsters. Children learn from Monkey King and use bowling pins to represent monsters. The game is introduced: bowling pins are a group of four. Children stand behind the prescribed line, play bowling pins, record and exchange their own game results, and help children consolidate their knowledge of the composition of 4 by combining objects.

The second is to test the ability of the little monkey, which is also to consolidate the knowledge that the child has learned by using the question-and-answer game, but without the support of specific images, it is helpful for the child to understand and master the abstract concept of numbers.
