Activity goal: 1. Learn to use and compare the number of two groups of objects in corresponding ways, and specifically perceive the number of objects. 2. Learn the skills of juxtaposing a group of objects and placing them under or to the right of another group of objects. Key point: let children learn to compare the number of two groups of objects in corresponding ways.

Difficulty: I will juxtapose one group of objects and put myself under another group of objects or on the lower right.

Activity preparation:

Magnetic teaching AIDS: 8 puppies, 7 cats and 6 fish.

Activity flow:

First, introduce the content of the class.

(1) First, put eight puppies in order.

Teacher: Many small guests came to visit our Class Two today. Let's see who is here.

Teacher: Oh, it's a puppy! How many puppies are there? (Guide children to talk more)

Second, demonstrate and ask questions.

(1) Arrange 7 cats one by one.

Teacher: Today, the puppy invited many kittens to their home, so let's look at the puppy.

Are there as many dogs as kittens? (Guide children to say different things)

Teacher: Let's talk about "there are not so many puppies and kittens".

(2) Inspire children to say that there are 1 dog and 1 cat.

Teacher: Please think about it. How can we have as many dogs and cats as possible? (plus 1

Only or minus 1 puppy).

(3) Inspire children to say that there are 1 cat and 1 fish, and try to make the number of cats and fish one.

There are many kinds.

Teacher: the kitten went to the puppy's house as a guest, and the puppy brought the kitten's favorite fish to entertain the kitten.

The teacher asked questions while demonstrating: Let's see if there are as many kittens and small fish together. There are many cats.

1 fish, 1 fish)

Teacher: Let's talk about "there are not so many puppies and kittens".

Teacher: Then the children use their little brains to think carefully about how to make kittens and fish become.

Is there that much? (plus 1 fish or minus 1 kitten).

Teacher's summary: By arranging the objects one by one, we can clearly see who has more objects and who has fewer objects in the two groups. Adding 1 or subtracting 1 to the objects with different numbers can make the objects with different numbers the same.

Third, summarize the activities, pack up the teaching AIDS and end the activities.

Teacher: Now children have learned how much to compare two objects. When they get home, they can also compare the things at home.
