Second, talk about introduction
(Showing the situation map of the textbook) Xiaoming learned to distinguish the four directions of east, west, north and south through the study of previous classes. Today, he brought a tool to indicate the direction and came to the campus playground again, ready to continue to learn more knowledge related to the direction. Guess what he brought? (compass)
Third, practice and accept new knowledge.
1, understand the history and usage of the compass, and enhance national pride.
(Show the compass chart) Students report the information collected in the communication preview 1, and the teacher summarizes it, focusing on how to use the compass to identify the direction:
The compass is used to indicate the direction. As early as more than two thousand years ago, our ancestors made a kind of directional instrument-Sina with magnets, and later invented the compass. Compass is one of the four great inventions in ancient China. The hands on the surface of a compass are influenced by the earth's magnetic field. The red end always points north, and the white end always points south. According to this principle, people use a compass to tell the direction.
According to the compass now, tell me what buildings are in the east, west, south and north directions of the campus. There are teaching buildings in the north, flower beds in the south, libraries in the east and gymnasiums in the west.
3. Know the southeast, northeast, southwest and northwest directions with the help of the marks on the compass.
Q: Where are the multifunctional halls and canteens on campus? how do you know
Guide students to sum up: from? East? At first, the direction between east, west, north and south is called northeast, and the direction between east, west, north and south is called southeast. From where? West? At first, the direction between west and north is called northwest, and the direction between west and south is called southwest.
4. Find out what buildings are in the southeast and northwest of the campus.
Fourth, consolidate the use.
1. Give a direction, and make a direction board after discussion. ? north
2. Use the direction board to identify the eight directions in the classroom.
Sit in your seat and tell me who your classmates are.
4. Exercise 2, Question 1, 2, 3.
5. Exercise 2, Question 4: Show me the map of China's administrative regions and ask: Which country does this map belong to? Educate students in patriotism in time.
Ask the students to find out the location of Beijing, the capital of China, and the location of Shiyan. What is the direction of Shiyan in Beijing and Wuhan and Beijing?
