The Decomposition and Composition of 7 large class lesson plan

As a teaching worker, you often need to prepare lesson plans, with the help of which you can effectively improve your teaching ability. How should I write a lesson plan? The following is my carefully arranged "Decomposition and Composition of 6" large class lesson plan, I hope to help you.

Activity Objectives

1. Through independent exploration and hands-on operation, children perceive the decomposition and composition of 6 and master the 5 divisions of 6.

2. On the basis of the decomposition of perceived numbers, grasp the increasing and decreasing laws of number composition.

3. Develop children's observation, analysis, and recording skills, and cultivate children's interest in mathematics.

Highlights of the activity

Perceive the relationship between the whole and the parts, learn and record the 5 divisions of 6.

Difficulty of the activity

Summarize the decomposition and composition law of numbers within 6.

Event preparation

Teaching aids, multi-** courseware.

The process of the activity

First, the beginning part

1. Game: Collision (review the decomposition and composition of 5).

Teacher: I said 5. J: I'm right 5

Division: 5 can be divided into 1 and several young: 5 can be divided into 1 and 4 (...)

Division: 5 can be divided into 4 and several young: 5 can be divided into 4 and 1

2. Review the divisions and several, and lead to 6 and 5 divisions.

3. In today's activity class, let's learn "The Decomposition and Composition of 6" together. (Present the topic and read it twice).

Second, the basic part

1. Children operate the building blocks with their hands, explore the five divisions of 6, and record the results of the exploration on the homework sheet.

2. Children do hands-on operation, and teachers inspect and guide.

3. Ask the children to report the results of the operation. Which child will tell the teacher the division of 6 you found?

Invite the children to speak and put their results on the board and compare).

4. Guide children to observe the split and combine of 6, what do you find? The numbers on the left are one more than one by one, which is called increasing, while the numbers on the right are one less than one by one, which is called decreasing.

There are also two sets of numbers that have been reversed, but the total number has not changed. This is the law of the decomposition of numbers.

5. Ask the children to demonstrate the 5 divisions of 6.

6. Read 6. Split-and-combine.

6 can be divided into 1 and 5, and 1 and 5 together are 6.

3. Concluding part

1. It's time for a little question mark: he wants to check the learning of our children.

1) (Presentation of courseware) Fill in the missing numbers.

2) (Presentation of courseware) Fill in the missing points.

2. Make games: In today's activity class, the children learned the decomposition and combination of 6, and knew how many divisions there are 6? (5 types) Let's play a game together.

Old: Kid, tell me, 6 can be divided into 1 and how many?

Young: Mr. Liu, let me tell you that 6 can be divided into 1 and 5.

Fourth, extension activities

The children in our class are really great, they have learned the decomposition and composition of 6 in such a short time, and now the teacher assigns a task to each of the children, if the children now have 6 peaches, and the teacher wants the children to share them with your parents to eat, then how should they be divided? Would it be okay to invite the children to share them with their parents when they go home?
