The mathematical cardinal number and ordinal number of the middle class are less than 5.
Activity objectives:

1, know the ordinal number within 5, and perceive the directionality of the ordinal number.

2, can correctly use "which" to represent the order of objects.

Activity preparation:

1, school tools: digital card 1-5

2. Teaching AIDS: pictures of small animals, drawings of green, red, blue, yellow and purple houses. Architectural map, small chairs in green, red, blue and yellow.

Activity flow:

First, create a situation of "small animals moving" to help children know the ordinal number within 5.

1. Guide the topic: Tell the child a good news! The small animals in the forest are moving to a new home! They also asked the children to help divide the house. Look! There are so many beautiful new houses in the forest community. What color are they?

Don't worry, let's talk one by one from left to right. Green, red, blue, yellow and purple. )

Hey, why don't these small houses have house numbers? Don't get lost when the little animals come. Tell you what, let's help them nail it together, shall we?

4. First count how many houses there are in a * * * and see how many house numbers to get.

5. Now confirm the number. Tell me, where is the green house? (Block 1) How many digits can it represent? (Children hold the "1" card, so choose a child's "1" and nail it on the house.)

6. Where is the purple house? Please count it carefully. What number can (No.5) be represented by? (Take some cards and nail them to the house)

7. Where is the yellow house? (Area 4)

8. Where is the red house? (Area 2)

9. Where is the blue house? (the third district)

Two, to further consolidate the ordinal number of the first to fifth.

1. If the number is nailed to the small house, the small animals won't get lost. I'll get it, okay? Look, who's here? (Puppy, squirrel, deer, rabbit, monkey)

2. How many small animals are there? (Count: 5. ) Five small houses are just enough to live in. Line up the houses quickly. ("Key" is displayed)

3. Where is the puppy ranked? (No.1) (We put the key of the first house on it "1") 4. Where is the little monkey ranked? (No.5) ("No.5")

5. Where is the deer? (No.3) ("No.3")

6. Where is the rabbit? (Fourth time) (-"4 ")

7. Where is the little squirrel? (No.2) (-"No.2")

The teacher concluded: Deer, pigs, bears, puppies and rabbits all moved into their new homes happily, so they were very happy. They sang and danced on the green grass in front of the new house, and they also said thank you to the children!

Third, learn to find the corresponding position according to ordinal number.

1. What's that noise? (showing the map of the small zoo) are kittens, lambs, birds, frogs and turtles. Oh, they are late and haven't found a suitable house yet! Let's help them find another room Do you have any vacant rooms?

There is a new building behind the lawn. Looking at the window, we can see that there are many vacant rooms. How many floors does this building have?

3. How many rooms are there on each floor? (collective number)

4. The little turtle said, I don't like living upstairs. I am so tired that I climb up and down every day. I just want to live on the first floor. Kid, can you help me find it? When you find my photo, please post it on the window of the new house.

5. The bird said: I like living in high places. I want to stay in the last room on the third floor. (Find and publish photos)

6. (Show lamb and kitten): Lamb and kitten are good friends. They want to live closer. Are there two adjoining rooms? Where is it?

7. (Looking for) There are two vacant rooms next to each other on the second floor. How many rooms are there? (From left to right) Please let the lambs and kittens live here.

Fourth, the game: "watching movies"

Are you happy that we helped so many small animals today? The small animals have all moved into their new homes. They are very happy. In order to thank us, the little animals invited the children to the cinema to watch cartoons. Now let's line up and watch them together.

1. Rules of the game: provide 4 rows of red, yellow, blue and green chairs, and affix the number 1-5 on the back of each row of chairs.

The teacher gave each child a red, yellow, blue and green movie ticket, and the seat number was written on each movie ticket. Children look for seats according to the color and seat number on the movie tickets.

Teacher's guidance: first, let the children carefully observe the color of the movie ticket and find the row with the corresponding color, and then find the seat according to the seat number on the movie ticket.

Children can buy tickets and find seats freely. Please tell them which row and seat they chose, or see which row and who are sitting in which seat. Then watch cartoons.
