Mathematical skills of first-year students in position recognition
The math skills in the first year of job identification are as follows:

1, find out:

Determine the left and right sides according to the positions of your left and right hands. The right hand is on the right and the left hand is on the left.

2, before and after understanding:

The meaning of front and back: generally speaking, it means that the direction facing is front and the direction facing is back.

The same object will also change its positional relationship relative to different reference objects.

From this, it is concluded that when determining the front-back position relationship of more than two objects, it is necessary to find the correct reference object, and the relative front-back position relationship will also change with different reference objects.

3, up and down:

Understand from the position of two objects: the upper refers to the high object and the lower refers to the low object.

4, left and right, front and back, up and down nursery rhymes:

Stretch out your left hand, stretch out your right hand, touch your left ear and touch your right ear; Pat your left shoulder, pat your right shoulder, stamp your left foot, stamp your right foot, and look up and down. Point forward and look back.

Expand knowledge:

Advanced position determination method:

1, use the compass:

Compass is a common tool to determine the direction. After keeping the compass horizontal and stabilizing the pointer, the pointer will point to the magnetic north pole of the earth, thus providing a direction to the north. According to the pointer, other directions (such as east, south and west) can be determined.

2. Observe the sun:

If it is during the day, you can use the sun to judge the direction. When the sun rises in the morning, it is in the east; At noon, the sun is at the highest point in the south; When the sun goes down in the evening, it is in the west. By observing the position of the sun, we can determine the general direction of east, west, north and south.

3. According to landmarks or maps:

When you are in a strange environment, you can refer to landmarks or maps to determine your direction. For example, maps with compass directions, street signs, building directions, etc. This information can help you determine your direction.

4. With the help of mobile phone applications or navigation devices:

There are many free navigation applications on mobile phones, which can provide the current position and direction by using the built-in GPS function. By downloading and using these applications, you can accurately determine your direction.

5. Observe the natural direction:

Some animals and plants are affected by the earth's magnetic field when looking for food or habitat. They can be used as direction indicators. Such as ants, birds and so on. Will show certain behavior when looking for direction, and you can observe their activities to judge the direction.
