1, understand the meaning of distance, learn to compare distances with tools, and learn to record preliminarily.

2. Experience the fun and success in the game.

Activity preparation:

Natural investigation experience.

2. Various tools that can be used to measure the distance: paper sticks, boxes, green tea bottles, books and small baskets. ...

3. Six small baskets containing 1 post-it notes, 1 record sheet, 1 marker, 1 chalk, 1 five-pointed star stickers.

4. A map.

Activity flow:

First, the visual distance.

1, children and teachers line up in the marching classroom and stand at attention.

Teacher: Who is farthest from Miss Huang? Who is closest to me?

2. Children sit in a semicircle.

Teacher: Who is farthest from me? Who is closest to me? how do you know

Summary: It turns out that visual inspection can be used to compare distances.

Second, the tool measures the distance.

1, a and b (they are sitting close together, so the distance from the teacher can't be seen visually). Who is near Miss Huang? Who is far away from me? (controversial)

2. What can we use to measure the distance when we can't see it visually? (Tools: such as hands and feet. )

Let a child measure with his hands or feet, and the teacher will observe and guide him.

Teacher: Now I stand up, and the stool represents my position.

(Forecast: 1. The children's measurement is correct: his measurement is really good. At the beginning, his hands or feet will touch his stool, and at the end, he will touch my stool.

2. The child's measurement is incorrect: at the beginning, his hands or feet should touch his stool, and at the end, he should touch my stool. One hand should touch the other hand, heel and toe should touch, and so on. )

4. Show all kinds of items in the box (paper sticks, boxes, green tea bottles, books, small baskets ...).

Teacher: I have many things here. Can they measure the distance?

Yang: Yes.

Teacher: I'll let a child try it. (The teacher corrected and guided in time)

Third, the long jump competition.

1, Competition: Just now we learned to measure distance with tools. Do you want to jump long? Now I ask the children to take a piece of material in groups of three, find an open space and post it in time. Everyone takes turns to jump, and the other two measure and record separately. Write the student number on the top line, the distance on the bottom line, and the star representing the champion on the farthest line.

2, check (focus on checking two records)

Fourth, extending activities-mapping maps.

Teacher: Just now, in the long jump competition, each group produced a champion. Now they will take part in the competition in the gymnasium on behalf of our class. This is a map from kindergarten to gymnasium. Can you understand?

Yang: There is a hotel on one road, a hospital on another road and a bank on the other road. ...

Teacher: Which way would you choose? Why?

Young: Being closer can save time.

Teacher: Which is the shortest way? Let's go back to the classroom and test together!
