Teacher: There are so many teachers coming to our class today. I want to know who can make a good impression on teachers, and who do they like best?

1, specially trained:

Teacher: Last time we learned the division of 2 and 3. Let's review it together.

Clap your hands: small hand preparation (2 can be divided into 1 and 1, 1 and 1 composition 2; 3 can be divided into 1 and 2, and 1 and 2 constitute 3; 3 can be divided into 2 and 1, and 2 and 1 form 3).

② Password:

Teacher: Great! Answer first: 2 can be divided by 1 and what number? Health: 1 and1;

Teacher: What number can 3 be divided by 1? Health: 1 and 2;

Teacher: Can 3 be divided by 2 and what is the sum? Health: 2 and 1.

2. Great! Children, there lives a mother rabbit in the forest. She has a problem. What is this? Let's see who can help mother rabbit solve this problem. Mother Rabbit has two clever and lovely children, one is Bao Bei and the other is Beibei. Today, Mother Rabbit pulled out four radishes (stickers) (What are four radishes? Write on the blackboard: 4) These four radishes should be distributed to the baby and Beibei (paste pictures and write "Divide into symbols"). But how should we divide it? Both Tutu and Beibei need radishes. You can help Mother Tutu share one point. (Find individual children to perform the score) Children who guide the demonstration after the score: 4 points and "points and" on the blackboard) Whose score is different? Write on the blackboard.

Teacher: Just now, everyone used their brains and thought of so many ways. It's really amazing. Then let's read the division of 4 together. The teacher guides reading. Boys read, girls read, clap your hands and read together.

Answer first: how much can 4 be divided by 3 and? What is the sum of 4 divided by 2? What number can 4 be divided by 1 and?

Teacher: It's amazing that you can help mother rabbit solve the problem so quickly. Do you know what we learned today? Division of 4. Look at the topic together.

3. rhythm:

Teacher: Now let's have a rest: find friends.

4. Classroom games:

Teacher: We have all played hide-and-seek games. Today I want to play with you: there is a number hidden under each picture. I choose the most beautiful child to guess. Other children guess silently in their hearts, don't say anything, and see if your guess about the same thing is different. Ask individual children to guess on the stage, and then take off the picture to see if it is correct. If it is correct, send the pictures to the children. And read this sharing together.

Teacher: Everyone guessed correctly just now, so I want to know who is the fastest. Now I invite my two favorite children to play the game of "grabbing cards". There are many beautiful digital cards on the podium, and each card has a number on it. Listen to my question carefully and see who grabs the cards quickly and accurately. Yes, 4 can be divided into 1 and what number? Robbery 3 ... and so on.
