What has been taught, how to teach, and what is the truth in the second volume of second-grade mathematics of Jiangsu Education Press?
Direction, position. Teaching methods should be based on specific topics. There is no fixed method. But there are fixed points: up north, down south, left west and right east. Let the students know the direction first and look at the pictures. Students know how to look at pictures, and teachers can understand them at a glance. Because this is an intuitive teaching, you need a picture to make it clear.

In each direction, students should first look at the picture from the positive direction of the central point (observation point), and then see which direction it deviates and how many degrees it deviates. The angle of deviation also depends on which positive direction is taken as the standard.

For example, take Fangfang's home as an observation point and talk about it.

At 70 degrees 500 meters east longitude.

? It's 15 degrees, 400 meters west of due north.

? At 52 degrees 700 meters south latitude.
