The content of learning mainly includes the following two aspects. First, by solving practical problems and understanding the method of determining the position, we can determine the specific position according to the direction and distance. Second, learn to look at the simple circuit diagram and tell the direction and route of walking according to the circuit diagram.
The key and difficult point of learning is to be able to mark the specific position of the object on the plane. In addition, students can have a huge gap in the learning process, and can flexibly describe the route according to the changes of observation points.
Knowledge points of position and direction in unit 2 of the first volume of mathematics in the sixth grade of primary school
The position and direction unit is mainly expanded and improved on the basis of the previous study. Mainly learn to determine the position of objects and describe simple road maps according to the two conditions of direction and distance. This chapter mainly determines the position of the object through the row and column where the object is located. Can describe a simple road map, in terms of direction representation, it will also involve measuring angles with a protractor.
In the learning process of expressing orientation, it should be noted that the direction deviation is determined according to the angle given by the topic. For example, if a given angle is close to the direction of four towns, then the direction representation will start from four directions: east, west, north and south, for example, 30 degrees south of east. Or 60 degrees east of south.
