People's Education Press, Grade Three, Volume II P3-P8.

Teaching objectives

1, through the life situation and students' life experience, let students identify the east, south, west and north directions and know the four directions on the map.

2, in the east, south, west and north, given a direction (east, south, west or north) to identify the other three directions, and can use these words to describe the direction of the object.

3. Ask students to identify the four directions of southeast, southwest, northeast and northwest, and know the four directions of southeast, southwest, northeast and northwest on the map.

4. With the help of realistic mathematics activities, cultivate students' awareness of distinguishing directions, develop the concept of space and experience the close relationship between mathematics and real life.

Emphasis and difficulty in teaching

1, teaching focus: know eight directions: east, west, south, north, southeast, southwest, northeast and northwest.

2. Teaching difficulties: quickly identify the southeast, southwest, northeast and northwest directions.

teaching process

First, the introduction of new courses.

Teacher: Do all the students know about the sun? Without the sun, there would be no light. Have the students ever observed the sun? Students discuss one after another. )

Student 1: The sun is round. Student 2: The sun rises in the east every day. Teacher: The students answered very well!

Teacher: (Multimedia demonstration) In the morning, the sun rises in the east. In the evening, the sun sets in the west.

Second, teach new lessons.

Teach east, west, north and south.

Teacher: Let's have a look at the aerial view of the school. The library is in the east of the campus. Where is the gymnasium on campus? Please answer the question.

Student: Lucy.

Teacher: This classmate learns quickly! Then let's see which side of the campus the teaching building is and which side the gate is. Please raise your hand and answer.

Student 1: The teaching building is in the north of the campus.

Student 2: The gate is in the south of the campus.

Teacher: Students are so clever! They all learn quickly.

Teacher: Let's read it together: face west, back is east, left is south, and right is north. Face north, back south, left west, right east. (Students read after it. )

Teacher: Let's look at the schematic diagram of the school again. Maps are usually drawn from north to south, left to west and right to east. The gate is under the playground, just south of the playground. Let's look at the following topic again.

The students answered questions enthusiastically, and the teacher affirmed and appreciated the students' correct answers.

Teacher: Let's look at the layout of Tiananmen Square and read it according to the map: Tiananmen Gate is in the north of the national flag, the Great Hall of the People is in the west of the Monument to the People's Heroes, and the National Museum of China is in the east of the Monument to the People's Heroes. (Students read after it. )

Then the teacher asked the students to answer the questions.

Teacher: Let's take a look at the aerial view of the campus again. Where is the restaurant, parking lot and science and technology building on campus? Let's think about it.

Student: The canteen is in the northwest corner of the campus, the parking lot is in the southeast corner, and the science and technology building is in the southwest corner. Teacher: Good answer! Now everyone can be a little guide. See who is willing to take the initiative to be a small tour guide? Students actively answer questions, and the teacher announces the answers, affirming the students who answered correctly and encouraging the students who answered incorrectly. )

Teacher: Everyone should like to go to the zoo! Then let's take a look at the schematic diagram of the zoo. Tell me where the animal activity place is in the flower bed. The students answered questions enthusiastically, and the teacher encouraged and affirmed the students' answers. )

Third, consolidate the practice.

Teacher: Let's look at the distribution of the central square of the street. Please answer the question: where are the banks, stations, parks and restaurants in the street garden? The teacher plays the courseware and asks the students to answer the questions. Affirm and praise students who answered correctly, encourage students who answered incorrectly, and encourage them to make persistent efforts next time. )

Fourth, summary.

What did you learn in this class? Do you know the direction?

The teaching plan of the position and direction of the second volume of mathematics in the third grade (1) (2) Teaching objectives: position and direction (1)

1. Cultivate students' sense of direction and develop the concept of space through realistic mathematical activities.

2. Make students know the four directions of east, south, west and north, and know that "east" and "west" are relative, and "south" and "north" are relative.

3. Know that the direction on the map is generally "up north and down south, left west and right east".

4. Be able to determine other directions according to one direction that has been set.

5. Experience the close relationship between mathematics and real life.

Teaching emphasis: be able to correctly identify the southeast and northwest in the real scene.

Teaching difficulty: given one direction, the other three directions can be identified.

Preparation before class: Before class, divide the students into four groups and sit in four different directions in the classroom.

First of all, introduce.

1. What words did we learn to express our position in the second grade? ("front, back, left and right").

Can you tell me something about your "back and forth" (please tell me two students with opposite positions, because they have different positions and say different things. )

2. Why do the two students speak differently?

The position indicated by "front, back, left and right" is relative to the observer. When the position of the observer changes, things like "front, back, left and right" will also change. )

3. Expose the topic:

People and things are always in a certain position and direction. Besides the "front, back, left and right" we already know, do you know any other words that indicate position or direction? [Board: Know the direction, southeast, northwest]

Second, know the direction of life.

1. How to distinguish these directions in life? Do you have any good ideas? The most commonly used methods are:

(1) In the morning, the sun rises in the east.

(2) At night, Polaris shines in the north.

(3) The compass can always point to the south. (It is required to focus on the first point and briefly introduce two or three. )

Students have so many good ways. Now, please point out the southeast and northwest directions of the classroom. For the classroom: where is the east of the classroom? Can I help you? What's in the south, west and north? Which direction is your group in the classroom? (Answer by name, the teacher gives help. )

3. After determining the direction, the students all stood up, facing east, a little southeast and northwest; Facing south, a little southeast and northwest; Facing west, a little southeast and northwest; Facing north, a little southeast and northwest.

4. Two students play games together. One student says the direction, and the other student faces in what direction.

The teacher stands among the students. Where are the teachers in your group?

Q: The teacher didn't move. Why in the east, in the west, in the south and in the north?

It seems that using "southeast northwest" to indicate the direction is the same as "front, back, left and right". Observing objects from different positions will have different directions, indicating that the directions are relative.

Third, know the direction on the map.

1. When we draw a map, we usually draw "North", "Up North, Down South, Left West, Right East" on it.

North =

Dong Xi

south

Which two directions are relative?

2. If you draw "North" on the right, what about the other three directions? The picture is below? What about the picture on the left? Tell me what you think.

3. Abide by the law:

( 1)

(2)

(3) The southeast and northwest are arranged clockwise. The east is on the right of the north. Turn right, then southeast and northwest.

Fourth, the application of direction.

1, for example 1:

(1) direction?

(2) Fill in the blanks. Look at the picture. Xiaoming is standing on the playground. What is to his east? South? West? North? How can you be sure?

Take a look in the corridor: suppose we stand between the library and the gymnasium, which direction is to our east? What's the matter? What's in the south, west and north? Teachers should guide students to observe according to the actual situation of the school. )

3. Look at the small picture on the second page: (the schematic diagram of Tiananmen Square in Beijing)

Suppose you stand in the middle, which way is north? Tell me about your buildings in the southeast and northwest.

Verb (short for verb) Task:
