1, through operation, guide children to master the formation of 7 and the relationship between 1 and 1.

2. Experience the fun of mathematical operation and exploration.

Second, the activity preparation:

Disposable plate, fork, 7 cake pictures, large demonstration board and smart box.

Highlights and difficulties of the activity:

Key points: Let children know that 6 plus 1 is 7 through arithmetic activities, and it can be described in words.

Difficulties: Know the relationship between numbers greater than 1 less than 1, and understand that there are 71in 7; Seven 1 adds up to seven.

Third, the activity process:

(A) Enter the game: "Mouse and Cat"

The mouse is going to buy a cake and meets a cat on the way. There was a cat among the six mice in the past. Let's see how many cats appear.

Let the children join hands in a big circle, and the teacher pointed at them one by one while saying nursery rhymes.

Children's Song: A little mouse went shopping for a cake and met a cat. Say "mouse" if you point to it. When it refers to six people, children will learn to meow. )

Example: mouse, mouse, mouse, mouse, mouse, mouse, cat. See which child counts clearly and responds fastest.

(2) Explain the operation:

1. Learn the formation of 7 through the story of cat and mouse eating cake.

The teacher said: Who did we invite just now? What do I mean by mouse? (pointing one by one) Now let's invite the mice out one by one!

Ask the child: How many mice are there? Let's count together.

The teacher summed up: 6 The mouse has come to a cat again. How many animals are there now?

Six mice and a cat are seven kinds of animals, and six plus 1 is seven.

2. The teacher took out six empty disposable plates as cake boxes, arranged them in order, and the children counted them.

Ask the children: (1) How many plates are there? (2) Are there as many animals as plates? Who is more and who is less? How much more? How much is missing?

The teacher said: we gave the mouse a plate, and the cat was not happy. How can I make six plates into seven plates?

Teacher's summary: Yes! 6 disks plus 1 disk (color) is 7 disks, and 6 disks plus 1 is 7.

3. Send cakes.

The teacher said, children, let's give each mouse a piece of cake! Please put the cakes on the plate one by one.

Ask the child: How did the cake get on the plate? 6 How many 1? Please count the number of children and tell the total.

The teacher said: the cat said I want to eat cake, too. Let's give it a cake, too! How many cakes are there? How many copies is 6 1?
