Written in the front: this question has nothing to do with the word "enhance physical fitness" First imagine that this big grid is a piece of cardboard, and then you cut it along those intersecting lines with scissors. Each cell is independent.

Each grid is an independent brand.

Together, it is a model (enhancing physical fitness)

(By the way, the small X under the written box is the person holding the sign. Did you get a look at him? There is a person under each grid)

"10*40" means 40 people in the horizontal station and 10 people in the vertical station (that is, those small ×).

What you need to answer this question is how to distribute this 10*40 board with the words "strengthening physical fitness" in a planned way to the people of 10*40 in an orderly manner (just like the symbol of a large-scale event like a sports meeting).

Solution:

This question should be related to the knowledge of Go in the picture below. The lines and columns of Go are marked with numbers, which should inspire you. The latitude and longitude on the earth are the same, and they will be after studying geography. )

Steps to solve the problem:

1. First mark 1~40( 1~ 10) from left to right (from top to bottom) on the diagram.

Just like the map of Go below, there are small numbers on the top and left. Do you see it? )

2. Then draw the corresponding pattern on the corresponding board according to the drawing.

(For example, the three rows and four columns on the picture are all red, so you can paint the corresponding boards red. )

3. The problem of orderly distribution is similar to the production steps, that is, the board corresponding to each person is assigned to the corresponding person.

(that is, if you stand in a row, the person standing in the corresponding position has a whiteboard in his hand)

4. as for the number, look at the picture.

I will learn rectangular coordinate system in junior high school, and that knowledge can also solve this problem.
