Ten plus a few do not carry addition lesson plan large class

First of all, write the teaching objectives, and now it is the stage of curriculum reform, and the new concept in class is divided into three parts: knowledge, ability, emotion, attitude, and values. Then analyze the textbook:

Key Points and Difficulties 3 Teaching Aids 4 Teaching Methods 5 The teaching process can be divided into detailed cases and brief cases, detailed cases should be conceived how to say each sentence is more troublesome, and the brief case only needs to write the time arrangement, and each part of the teacher's activities and students' activities 6 Board book outline 7 Teaching feedback Such a teaching plan is more complete and can also summarize the problem in a timely manner. I think the most important thing in writing a lesson plan is to establish the teaching concept first, that is, the first part, and you must not underestimate this part, otherwise the class will be aimless and the effect will be poor.

Writing a good lesson plan is the basic condition for ensuring the success of teaching and improving the quality of teaching. The pedagogical process is a bilateral process of activity consisting of the teacher's teaching and the student's learning. Teaching success and improving the quality of teaching are twofold:

First, it refers to the basic knowledge, skills and techniques that students must master as stipulated in the syllabus, which should be deeply and thoroughly understood, and can be firmly memorized and mastered proficiently; On the other hand, on the basis of mastering the prescribed basic knowledge, skills and techniques, students are required to give full play to their enthusiasm and creativity in learning, and apply the basic knowledge they have mastered to relevant problems to understand, analyze and solve new problems. In order to achieve such a goal, it is necessary to fully understand the laws of students' cognition and physical and mental development before teaching, design a teaching plan that conforms to objective laws according to the specific characteristics of the physics teaching process, and teach in a targeted manner according to the teaching rules. If you don't write the lesson plan carefully, you will inevitably have vague goals, countless hearts, improper requirements, and arbitrariness in the teaching process, and it is impossible to achieve good teaching results.

Teaching Objectives:

1. Make students calculate the carry addition of two digits plus two digits within 50.

2. To enable students to use what they have learned to solve problems in life.

3. Cultivate students' sense of cooperation and the ability to summarize calculation methods through practical operations.

Teaching process: 1. Introduction of new lesson situations:

In the multi-** classroom, there were originally 38 chairs for the teacher, and 25 chairs were borrowed in order to allow more teachers to listen to the class. Please help me think about it, there are about 60 teachers coming to the class, can you sit down?

1. In addition to using the estimation method to know that 60 people are not enough seats, we can also use the method of accurate calculation to solve this problem. (Paste this question).

2. If you want to know if 60 people are enough to sit, what do you need to ask for first? (There are a few chairs).

3. Who can make an equation based on this content? (Board Book 38-25).

Board book topic: two digits plus two digits).

Today we will learn the carry addition of two digits to two digits.

4. Think about what methods you can use to calculate this problem? Next, please talk about your good algorithm with your group classmates, or you can use learning tools to set it up. I will invite the representatives of the group to come and talk to you in a moment.

5. Which student would like to talk about different algorithms on behalf of the group?

Report and exchange, teacher board book method).

The method of pen calculation.

6 3 Methods of oral arithmetic.

How to swing a stick.

Ask a student to come to the projector and set it up with school tools.

6. Use your method to calculate, although the numbers are correct, but let's take a look at which method is better to calculate?

7. The vertical method is simpler and less prone to errors. Vertical calculations are also called pen calculations. So what should we pay attention to when calculating? (Summary).

Identical digit alignment; Counted from single digits; If the unit digit is full of 10 digits and further one to the ten digits, you can mark the carry position "1".

2. New lesson content exercises:

1. (Problems in life) Do an exercise on page 12 of the math book. Students do the calculations in a row, and then check each other's correctness and error at the same table.

2. Game (apple picking).

Ask the students who are doing well to play a game with the teacher, and guess how many are hidden behind the apples? Whoever guesses correctly will be rewarded with apples.

03. Please play a game (test your eyesight).

Judging and correcting the wrong question, whoever finds the problem will raise his finger first.

3. Lesson Extension:

Capture the Red Flag Competition.

Everyone learned very well in this class. Would you like to show off your skills? Okay, let's take a red flag game in the group, and the winning group will plant the flag of victory. Listen to the requirements of the competition:

4 players are selected from each group to compete;

Which group completes the task first and most accurately will win;

After watching the Olympic games, the audience should be quiet so as not to affect the good performance of the players on the field, so please be a civilized little spectator.

Enter a yarn, and the big baby will teach these, and after teaching, I really don't know what they should learn in a few years of primary school.
