Teaching objectives:
(1) Make students know the four directions of east, south, west and north, cultivate students' awareness of distinguishing directions, and further develop the concept of space.
(2) According to the specific situation, we can use a given direction to identify the other three directions, and we can use these words to describe the direction of an object.
(3) By allowing students to speak, draw and move, students' ability to recognize and identify the four directions is strengthened, and the position of objects can be flexibly determined according to the directions.
(4) Integrate rich life materials into teaching, create vivid and interesting situations, cultivate students' ability to think from multiple angles and appreciate the diversity of problem-solving strategies.
Teaching emphasis: identify the east, south, west and north directions, and use these words to describe the direction of objects.
Difficulties in teaching: Under specific circumstances, we can determine the other three directions according to a given direction.
Teaching AIDS: campus situation map, multimedia courseware.
Teaching process:
First, connect with reality and introduce new courses.
Teacher: shall we introduce the location of the school in the new semester? (Exhibition theme: location and direction)
Teacher: Today we use new knowledge from east, west, north and south to help us identify the direction.
Second, contact life and explore independently.
(1) Learn to distinguish between east, west, north and south.
1. Looking for Mathematics in Life
Teacher: In your life, have you ever observed which direction the sun rises?
Teacher: Now sit in the classroom and observe. Which direction can you draw the sun on the blackboard? Name a student to draw, and the teacher indicated that the rising direction of the sun is the east. )
Teacher: From the position of the sun on the blackboard, can you know which side of our classroom is the east? Please face the east.
2. Group discussion and cooperative inquiry
Teacher: We know the East with the help of the sun. How do we determine the other direction?
3. The game is exciting and consolidated.
(1) Use gestures to indicate orientation.
When the teacher says a direction, the students will quickly point out their fingers (requiring students to master knowledge skillfully and cultivate quick response ability)
(2) turn quickly to determine the position
Teacher: facing north (student: front north, back south, left west, right east)
Facing south (health: front south, back north, Zuo Dong, right west)
Facing the east (health: front east, back west, left north, right south)
Facing the west (health: front west, back east, left south, right north)
(2) Describe the direction of an object with east, south, west and north.
1. Describe what objects are in the classroom in four directions: east, south, west and north?
2. Simulate the scene: tell the location of the object.
Teacher: please invite four students to play in the amusement park in the park. They are the Marine Animal Hall and the Circus Performance Hall.
Dolphin swimming pool, children's film and television hall.
Please ask four students to stand in the east, west, south and north directions respectively, and then ask two students to act as tourists and tour guides respectively.
Tourist: Excuse me, how can I get to the Marine Animal Museum?
Guide: Go east.
………
Introduce your room.
Teacher: Who can tell you how to decorate their room with our directional knowledge?
Teacher: Please draw a simple room layout of XXX on paper.
(C) apply what you have learned
Students observe carefully on the playground first, and then introduce each other in pairs.
1. Students use east, south, west and north to describe objects in all directions on campus.
2. Students introduce the direction of objects on campus.
3. A student asks and answers, trying to find the destination according to the given direction.
Third, summary:
When determining the direction, we must first determine one direction, and then determine the other three directions according to the principle of relative east and west and relative north and south.
Fourth, the blackboard design:
Position and direction
Sun (East)
