Kindergarten mathematics lesson plan "Addition and subtraction of 5"

As a conscientious people’s teacher, you often need to use lesson plans. With the help of lesson plans, you can effectively improve your teaching ability. So do you know how to write a formal lesson plan? The following is a kindergarten mathematics lesson plan "Addition and Subtraction of 5" that I carefully compiled. You are welcome to learn from it and refer to it. I hope it will be helpful to you. Kindergarten mathematics lesson plan "Addition and subtraction of 5" 1

Activity goals

1. Be able to use visual representations to perform addition and subtraction operations of numbers within 5, and be able to express the operation process in language.

2. Develop representational thinking.

3. Cultivate children’s ability to understand numbers.

4. Let children learn simple math problems.

Key points and difficulties

1. Key points: Understand the meaning of addition and subtraction.

2. Difficulty: express the operation process in language.

Materials and environment creation

1. Materials: plastic animals, snowflakes and other items. Number cards from 1-5. Picture cards with addition and subtraction diagrams. seal.

2. Environment creation: Place the above materials in the math area, let children manipulate them, and conduct exploration and review consolidation activities.

Design ideas

Oral addition and subtraction is the beginning of children learning addition and subtraction operations. The focus of the activity is to let children understand the meaning of addition and subtraction. In teaching, it is necessary to avoid causing children to form wrong thinking stereotypes, that is, if "一***" in the question means addition, and if "left" means subtraction. When designing, children can be exposed to different expression methods through illustrations or direct demonstrations, such as addition. One is to "merge" two partial numbers, and the other is to "add a few" on the basis of a partial number. Another example is subtraction. One is to remove a part from the total and find the remaining part. The other is to know the total and the remaining part and find the reduced part. Use concrete images to help children combine the mental operations of adding or dividing with addition and subtraction, so that children can truly understand the meaning of addition and subtraction.

Another goal of this activity is to develop children’s representational thinking. Because representation is the intermediary in the transition from concrete image thinking to abstract logical thinking. Children must master addition and subtraction through manipulation and using representation to perform calculations. Finally, the calculation of abstract numbers can be achieved. Therefore, when designing, we must first allow children to accumulate rich representations, and then encourage children to use representations to perform calculations by answering oral word problems. In addition, requiring children to express the calculation process in language is also an effective method to improve children's representational thinking level. However, children will have certain difficulties at the beginning. Appropriate visual teaching aids can be provided during teaching to help children clarify their ideas.

Activity process

Operational experience—gt; discussion and understanding—gt; review and consolidation

1. Operation.

(1) Physical operation. Let children use small plastic animals, snowflakes and other items to perform addition and subtraction calculations, and use corresponding number cards to express calculation results. For example, if you calculate three little white rabbits and two little gray rabbits, how many little rabbits are there together?

(2) Calculate by looking at the picture. Let children perform addition and subtraction operations according to the pictures. Ask children to describe the picture first and then calculate the result.

Note: The diagrams provided must have different ways of expressing addition and subtraction. For example, addition, some are calculating the total number of fruits on two plates. There were a few children playing, and a few more came over...

2. Discussion.

(1) Provide visual teaching aids to help children understand the meaning of addition and subtraction.

(2) The teacher composes word problems orally, and the children use visual representations to calculate and explain the calculation process.

(3) Oral composition problems for young children.

3. Review.

Children use animal, fruit and other seals to make addition and subtraction picture cards, and answer the addition and subtraction questions on the cards made by their peers.

Reflection on the activity

"Addition within 5" is taught based on students' knowledge of numbers within 5 and preliminary understanding of the meaning of addition. The "Standards" believe: "Due to the different life backgrounds and thinking perspectives of students, the methods used must be diverse. Teachers should respect students' ideas, encourage students to think independently, and promote the diversity of calculation methods." Therefore, according to the characteristics of students, I designed The following teaching links:

1. Review and preparation. Let the students place the learning tools, first 3, then 5, then divide the 3 into two piles, and divide the 5 into two piles, and talk about how to divide them. Let students recall the components within 5 they have learned and prepare for addition within 5.

2. Explore new knowledge. Use the dynamic images of multimedia courseware to attract students' attention. After asking the students to tell the meaning of the picture, let the students take out small sticks instead of balloons and swing them. Let the students know that adding the balloons on the clown's hands requires addition. While speaking, they use gestures to express the combination. The students really want to Show that you know how to do it, and strive to "put it all together" while talking and doing it. At this time, let more students talk about it to deepen the impression. Then ask students to list the addition formulas and guide them to recognize the plus sign. After the formula is listed, ask students to talk about what each number in the formula represents and what it means to prepare for learning to solve problems. When calculating the result, ask students how they calculated it. Some students said they thought of the division and combination formulas, and some said they calculated them by counting. We did not emphasize a certain idea, but affirmed each one. We encouraged students to use different methods and wait until they can do larger numbers in the future. When adding, it is up to the students to choose the most convenient and appropriate method, leaving them room to think.

3. Layered exercises. First, let the students hold 3 small sticks in their left hand and 2 small sticks in their right hand. Ask how many sticks there are in one. Experience that when the sticks in the two hands are combined, it becomes 3 2 = 5. How many times will this game be played? After the second time, let the students read the book p24 and "do it" and explain the meaning of the expression. For the third picture, some students could tell the meaning of the formula from the characters on the picture, and some could tell the meaning of the formula from the paper cranes on the table. They all gave positive feedback.

This lesson strives to embody the concept of "respecting students and focusing on development". Through students' observation, independent exploration, operation, and expression, students can feel and understand the generation and development process of knowledge, and experience the discovery of mathematics. fun. At the same time, after teaching, I feel that the diversity and interest of exercises need to be improved. Kindergarten math lesson plan "Addition and subtraction within 5" 2

Activity design background

Addition and subtraction within 5 is the basis for addition and subtraction within 10. Students learn the basics from kindergarten. Calculation is difficult for some students, but most students have better mastery. Therefore, I focus my teaching on the connection between perceptual number calculation and life, and experience addition and subtraction in specific situations and activities. The meaning of this content comes from above.

Activity goals

1. Let children understand the meaning of addition and subtraction.

2. Let children master the addition and subtraction of 5.

3. Enable children to learn to answer simple oral addition and subtraction word problems, and develop their ability to initially analyze problems.

4. Sing along with the melody of the song.

5. Able to sing the tune accurately, enunciate clearly, and be able to sing boldly in front of the group.

Teaching focus and difficulty

Enable children to learn to answer simple oral addition and subtraction word problems, and develop children's ability to initially analyze problems.

Activity process

1. Introduce the conversation and arouse children’s interest.

2. Review the components of 5

3. Provide visual teaching aids

4. Guide children to verbalize the addition and subtraction word problems of 5

5. Play the "who is the fastest" game

6. Write calculations

7. Teacher summary

Teaching reflection

1 , contact students' real life, let students realize that addition and subtraction are all around us.

2. The actual life of students allows students to realize that addition and subtraction are all around us.

3. To enable students to do oral arithmetic correctly and quickly, they must be trained regularly through a variety of exercises. I actively advocate the diversification of algorithms and provide students with opportunities for mathematical communication. The purpose is to promote students' mathematical thinking activities and improve students' mathematical thinking abilities. Due to the promotion of diversification of algorithms, different students have different problem-solving strategies. They will use their own methods to solve problems and have in-depth experience in solving mathematical problems, thereby gaining experience in learning mathematics. These algorithms are the result of students' thinking based on their existing basic knowledge and life experience. Each different algorithm represents an innovative consciousness, thus effectively training divergent thinking. Kindergarten math lesson plan "Addition and subtraction of 5" 3

Design intention:

This semester, children in the top class have begun to learn the division and combination of numbers and the addition and subtraction of numbers within 10 , in view of the situation where children’s image thinking is dominant and logical thinking is almost non-existent, I integrated the learning of mathematics into activities such as stories, pictures, games, etc., and achieved relatively good results. Children learn with ease and ease in this learning atmosphere, and the teaching goals are accomplished unconsciously. This is how we designed this math activity.

C Game: Question and Answer Teacher: Children, let me ask you, 23=? Student: Teacher, tell you 2 3 = 5 and finish all the calculations in sequence. After getting familiar with the game, children can ask each other questions and answers to consolidate addition and subtraction calculations.

D rush answer: Who is the fastest?

The teacher prepares some oral addition and subtraction word problems , teachers and students rush to answer and compare, who is the fastest? For example: 3 ducks swam in the river, and 2 ducks swam, how many ducks were there in one day? (The one with the most correct answers is If you win, you can get rewards from the teacher. Teacher summary: Praise the children who actively answer the questions, encourage the children who are relatively inactive, and lead the children to consolidate their knowledge again.

Activity extension: Ask the children to do the addition and subtraction they learned today. Share it with your parents or good friends

Reflection on the activity:

In this activity, teachers can create mathematical situations based on the spirit of the "Outline" and provide intuitive and operable materials. Various teaching methods are used to trigger children's observation, thinking, exploration, and operation, which effectively trains children's multi-directional thinking and mobilizes children's enthusiasm and initiative in learning. Kindergarten Math Lesson Plan "Addition and Subtraction of 5" 4

Design intention:

Mathematics is a subject with strong abstraction and logic. When organizing teaching, children often feel that their interest is not high and their desire to take the initiative to learn is not high. Strong. The "Outline" clearly states that games are basic activities for children. In order to create a space for children to actively explore and learn, I created a game situation space for children to "deploy the supermarket" and "buy." Actively gain relevant experience in "addition and subtraction of 5" in a series of operations and game activities such as "Activities".
