Mathematics Understanding the Near and Far large class activity design

Activity objectives: 1. Understand the meaning of distance and proximity, learn to use tools to measure distance, and learn to record preliminarily.

2. Experience the fun and sense of success in the game.

Preparation for the activity: 1. Experience in natural measurement.

2. All kinds of tools that can be used to measure distance: paper sticks, boxes, green tea bottles, books, small baskets, ......

A small basket containing 1 sticky note, 1 record sheet, 1 marker, 1 chalk, and 1 pentagram sticker.

4. A map.

Activity process: 1. Visual inspection of distance and proximity.

1. The children line up and follow the teacher into the classroom and stand upright.

Teacher: Who is the farthest away from Teacher Huang? Who's closest to me?

2. Children sit in a semicircle.

Teacher: Who is the farthest away from me? Who's closest to me? How do you know?

Summary: It turns out that visual inspection can be compared between distance and proximity.

Second, the tool measures the distance.

1. A and B (the two sit relatively close to each other and can't visually detect the distance from the teacher) Who is closer to Teacher Huang? Who's far away from me? (disputed).

2. What can we use to measure the distance when it is not visible to the eye? (Tools: e.g. hands, feet, etc.).

3. Ask a child to measure with his hands or feet, and the teacher will observe and guide.

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

**：1.The toddler measured correctly: he measured so well that his hands or feet would touch his stool at the beginning and my stool at the end.

2.The toddler's measurement is incorrect: at the beginning of the measurement, the hand or foot should touch his stool, and at the end of the measurement, he should touch my stool. One hand should touch the other, the heel of the toe should touch, etc. ）

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

Teacher: I have a lot of things here, can they measure the distance?

Young: Yes. Teacher: I'll ask a child to try it. (Timely correction and guidance by the division).

3. Long jump competition.

1. Competition: Just now we learned to use tools to measure distance. Would you like to have a long jump competition?

Now I ask the children to go in groups of three to get a material, find an open space, paste a timely sticker, everyone takes turns to jump, jump to where to use chalk to make a mark, the other two people measure and make a record respectively, the upper line of the record sheet writes the school number, the lower line writes the distance, and the farthest one is pasted with the star representing the champion.

2. Inspection (focus on checking two record sheets).

4. Extension Activities - Survey Maps.

Teacher: In the long jump competition just now, each group produced a champion, and now they are going to the gymnasium to participate in the competition on behalf of our class. This is a map from kindergarten to gymnasium, can you read it?

Young: There is a hotel on one road, a hospital on one road, and a bank ...... on one road

Teacher: Which path will you choose? Why?

Young: Near, which can save time.

Teacher: Which road is the closest? Let's go back to the classroom and measure it together!

Hope it helps!!
