1. Children can compare the number of objects in two groups by overlapping method.

2. Find out the extra parts of a group of objects and place them from left to right.

3. Children like to participate in math activities and can get happiness from them.

2. Activity preparation:

1. Each child has 4 large discs and 3 small discs.

2. Picture: 4 bears, 3 biscuits, and some headdresses for mice and cats. There are 4 circles on the ground, and each circle can accommodate 7 children.

III. Activity process:

L. Question pouring: Show pictures of bears and cookies. Teacher: We give bears cookies to eat. One bear can only get one cookie. Let's see, are there more bears or cookies?

teacher: "how do you know?"

The teacher demonstrates on the blackboard: put the bear cards on the blackboard one by one, and let the children pay attention to how the teacher places the bear cards (the hand moves from left to right). Then, put cookies on the bears one by one, and say, "Here's a cookie." And let the children pay attention to the direction of the teacher's hand movements. Teacher: Which is more bears and biscuits, which is less? Please take out the extra ones.

2, children's operation. Let the children take the large and small discs in each hand and have a look. Which one is more, which one is less, or is it the same? Then one by one-put the big round pieces on the table, and put the small round pieces on the big round pieces one by one. (Pay attention to the direction of hand placement) Tell which one is more and which one is less. Show more to everyone.

Note: When teachers ask questions again, they should encourage children to take part in the answers, and praise the positive children in time.

3. Game: Cats catch mice.

Dress the children in headdresses, the music is loud, and every four cats and three mice dance around the circle. As soon as the music stops, each cat quickly catches a mouse, and then tells the cat and the mouse, who is more than who, who is less than who, so that more people can come forward.

note: cats and mice can only move in their own circles; There is one more mouse than cat when playing the game again.

IV. Summary of activities:

Teachers summarize children's performance today, and praise and encourage children who are active in activities. Let children feel the joy of mathematics activities while operating. At the same time, teachers should take care of the children who are quiet in the activities, so that they can get happiness at the end of the activities, so as to cultivate their interest in mathematics activities.
