I. Activity objectives:

1, learn the adjacent numbers within 5, and let the children know that the adjacent numbers of 2, 3 and 4 are 1 and 3, 2 and 4, 3 and 5.

2. Understand the simple relationship between adjacent numbers and apply it to real life.

3. Cultivate children's concentration, imagination and helpful spirit.

Second, the activity preparation:

Digital card (1-5), 5 rooms, 5 guest cards, 1-5 digital brooch, and children are equipped with an operating tool and a creative card.

Third, the activity process:

(1) arouses children's interest in operation, and puts it on the table to find the relationship between the multiple neighbors of 1 and the minority neighbors of 1.

(1) Today, a little guest who is deeply loved by children came to our class. He came to learn new skills with the children. (Showing his joy) I'm glad to hear that the children in our class love to do things and use their brains. He wants to compete with us. Let the children take out their learning tools and put them on the table. Compare with Joy to see who finds the law of numbers first.

(2) Individual children answer and the teacher summarizes.

(3) Summary: The middle small disk is one more than the front small disk, and the middle small disk is one less than the back small disk. 2 is 1 greater than 1, 2 is 1 less than 3, 3 is 1 greater than 2, 3 is 1 less than 4, 4 is 1 greater than 3, and 4 is 1 less than 5.

(2) Understand the simple relationship between adjacent numbers.

1, Xiyangyang said that the child is so smart and really happy with you. Do you want me to invite some good friends to play with you?

2. Show lazy, boiling sheep, beautiful sheep, slow sheep. With so many guests coming, we arranged a beautiful house for each of them. The teacher asked the children to help them move into the new home, numbered the houses in turn and sent the sheep to the new home.

3. Guide children to know the adjacent numbers. We saw lazy sheep, boiling sheep, beautiful sheep and slow sheep all moved into new homes. 1 lazy sheep, 2 boiling sheep, 3 pleasant sheep, 4 American sheep, 5 slow sheep. They all have neighbors, No.2 Boiling Sheep. Its neighbors are lazy sheep living in room 1 and pleasant sheep living in room 3.

4. Boiling sheep has neighbors, and so does our digital baby 2. Who are its neighbors? Numbers 1 and 3, the children just put a small disc, 2 is the central number, 2 is the front 1 more, 2 is the back 1 less than 3, 1 and 3 is 1 less than 2,/kloc.

Adjacent numbers are numbers arranged in sequence, one number is less than the other 1, and the other number is more than the other 1.

Children know that the neighbors of No.2 boiling sheep are lazy sheep living in room 1 and pleasant sheep living in room 3. Who are the neighbors of Pleasant Goat and Beautiful Goat? Who are the neighbors of 3 and 4? Why?

Summary: The adjacencies of 2 are 1 and 3, 3 is 2 and 4, and 4 is 3 and 5.
