teaching process
First, situational introduction
1. Multimedia display the pictures on the second page of the textbook. Please observe first. What is this place? What do you see? According to the students, patriotism education should be carried out in time.
2. Question and discussion: If you stand in Tiananmen Square, can you describe the buildings around you?
3. Students can communicate freely and speak freely.
4. Summary: The students all spoke very well. Why are the buildings around us different? This is because the buildings we face are different, so the buildings in other directions have also changed.
5. reveal the topic.
Teacher: Through the study just now, we know that the locative words we have learned before: "front, back, left and right" have certain relativity. In this lesson, we will know new locative words-East, South, West and North.
It says on the blackboard: Southeast, Northwest.
Second, observe the feelings
(Teachers and students go to the playground together)
1. Know the direction.
(1) Understanding the East
Teacher: Do you know in which Fang Xiangsheng the sun rises? Which way is east? Look at what is on the east side of the playground.
Ask the students to point to the east and talk about what is in the east of the playground.
(2) Understanding the West
Teacher: How did we find the East just now? Do you know which way is west? How did you find it?
[learning method attempt: I already know the east, and the opposite of the east is the west, so I found the west; I also know that the sun sets in the west, so the setting side of the sun is the west. ] according to the students' answers, the teacher leads the students to say in chorus and make gestures: the sun rises in the east in the morning and sets in the west in the afternoon.
(3) Understanding the South and the North
Just now we found the east and the west. Please look around the playground, and you will find it.
North and south?
(2) Communication: Which direction did you find? What is to the south of the playground? What about the north of the playground?
2. Feedback exercises.
(1) Ask the students to line up, face east and close their eyes.
Q: Where are we facing? Which direction is in the back? Which direction is left and right?
(2) Turn around and face south. What are the directions of back, front, left and right?
[Learning method attempt: 1. My front faces south, and my back must be north, so my left is east and my right is west; 2. My front faces north, my back faces south, my left side faces west and my right side faces east; My front is the east, my right is the south, my back is the west and my left is the north.
According to the students' answers, the teacher gives correct guidance.
(3) think about it. What if you turn around again and face west and north? Chat with your good friends.
(4) Communication: Who is your good friend? What did he say?
(5) Discussion: Through the practice just now, will you determine the other three directions according to a given direction?
Students communicate and the teacher summarizes.
[Reflection on learning methods: I understand that the east, west, north and south are fixed directions. No matter which direction people face, east, south, west and north are its fixed directions, east and west are opposite directions, and north and south are opposite directions. ]
3. Game integration.
(1) The teacher reads nursery rhymes and the students do actions:
The chicken took two steps to the east.
The duckling took three steps back to the west.
The kitten stretched out to the south,
The rabbit jumped north three times.
(2) Name two people on stage, the teacher reads the password and the students perform.
(3) Name students as commanders, and the whole class will act according to nursery rhymes.
4. Draw a schematic diagram.
(1) Students take out the prepared cardboard, and the teacher demonstrates: determine a direction on the cardboard. Can you determine the other three directions according to this direction?
(2) Students divide into groups and determine their positions on the cardboard.
(3) the direction on the 3)AC cardboard.
(4) Summary: Some students set the top of the cardboard to the east, and some students set it to the west, south and north, which is very good. As long as one direction is set, the other three directions are determined. However, on the map we are looking at, it is usually drawn by setting the top to the north. Try it. Set the top to north. Can you write down the other three directions?
(5) After the students write it out, the teacher guides the summary: the map is generally drawn from north to south, left to west and right to east.
(6) Fill in the schematic board.
Take a look. What's in the north of the playground? (teaching building)
According to the students' answers, the teacher writes the word "teaching building" in the corresponding position on the cardboard.
② What are the other three sides? Can you fill them on the cardboard?
Teamwork, * * * with the production plan.
Communicate, take out your own schematic diagram and introduce it to teachers or classmates.
Third, consolidate the practice.
(Students line up to go back to the classroom and sit down)
Take a look at the length. Which direction are we facing now? Which direction does the teacher face?
2. Tell me about it.
The teacher is on our () side, we face () side, followed by () side, left side is () side, and right side is () side.
Fourth, class summary.
What did you learn from this course? Can you tell us something about it?
Verb (abbreviation for verb) homework after class
1. Exercise 1, Question 1 and 2.
Do you know that in our life, besides relying on the sun, there are many ways to tell the direction?
Coach innovation
After-class practical guidance
Exercise 1: Question 1, identify the east, south, west and north directions in the classroom, aiming to help students identify the southeast and northwest directions, and use these words to describe the position of objects. In teaching, teachers should identify other directions by pointing out one direction to students, and then let students talk about it in combination with real scenes in class, so as to give timely guidance.
Exercise 1, question 2, is a practical topic. The purpose is to let students apply what they have learned about direction to real life, understand the relationship between mathematics and daily life, and cultivate students' awareness of applying mathematics. In teaching, students can draw a schematic diagram of their own rooms first, and then discuss in groups. Students at the same table can also cooperate in class, one student said, one student draws a schematic diagram.
