Second, the analysis of academic situation: Students have accumulated some perceptual experience in their daily life. Through the study in the first school year, they will use up, down, left, right, front and back to describe the relative position of objects. On this basis, this unit enables students to learn to identify eight directions: east, south, west, north, northeast, northwest, southeast and southwest, and to know a simple road map.
Third, the teaching objectives:
1. Knowledge and skills: Combining with specific situations, make students know the four directions of east, south, west and north, identify the other four directions with a given direction (east, south, west or north), and use these words to describe the direction of objects;
2. Process and method: enrich the experience of counterpart knowledge through observation, operation, imagination, description, expression and communication;
3. Emotion, attitude and values: Through realistic mathematics activities, let students learn to identify the direction and further develop the concept of space. Enhance the interest in exploring mathematical laws in activities and accumulate positive mathematics learning emotions.
Emphasis and difficulty in teaching: make students know the four directions of east, south, west and north, identify the other three directions with a given direction, and use these words to describe the direction of objects, so that students can know the direction on the map.
5. Preparation before class: arrange students to observe the buildings in four directions on campus before class; Ruler, draft paper; Multimedia courseware.
Sixth, the teaching process.
(A) contact life, create a situation
1. What schools are there in Tongbei Town? Who can introduce the teacher?
(2) The students answered "One primary school, two primary schools, three primary schools, one middle school and two middle schools". Every time students say a school, they play pictures of the relevant schools with multimedia. )
(3) Summary: The students named all the schools in Tongbei. When shall we visit them? Please tell the teacher where they are in our school.
(4) answer.
The courseware shows the panoramic view of Tiananmen Square and asks students to introduce the surrounding buildings centered on Chairman Mao Memorial Hall.
Summary: The teacher knows that many students in our class have made friends from east, west, north and south. Today, in this class, we will learn the position and direction. (blackboard writing topic)
Design intention: The existing knowledge stimulates students' interest and confidence in exploration. Students will use what they already know to describe the positional relationship between them, such as front, back, left and right, and some students will tell the four directions of east, west, north and south.
(B) to mobilize the original experience, a preliminary sense of direction.
1. Teacher: Students, we often encounter the problem of direction in our daily life. Do you know any other knowledge or vocabulary related to the southeast and northwest?
Teacher: There seems to be a lot of knowledge about the southeast and northwest. So how do you tell the direction in real life? Today we will go to the playground to find these directions.
2. Express the theme that the sun rises in the east.
Teacher: Students, now we face the East together. If we know the East, how can we identify the other three directions?
Please recall the children's song in the first grade Chinese class: get up in the morning, face the sun, the front is east, the back is west, the left is north and the right is south. Ask the students to go to the East Station and tell them that the direction of their backs is west. Then let the students open their arms, pointing their left hand to the north and their right hand to the south. )
Teacher: Then can you fill in the blanks according to this picture?
The library is on campus and the gymnasium is on campus.
The teaching building is on the _ _ side of the campus, and the gate is on the _ _ side of the campus.
(3) manufacturing a directional plate
1. Teacher: In order to help children better identify the direction, we draw these four directions on a picture, which becomes the direction board. You see, this direction card shows us the direction of the north. Can you tell me the other direction quickly? Please take out your own direction board, write and compare.
2. Play the answer game first. The teacher shows the blank direction board marked north, and the students answer the other directions first.
(d) Practical activities-making school maps.
1. Teacher: Students, now let's go to the playground together. Standing in the middle of the playground, what are the four directions you see? Draw them and mark them with names. Let's make a campus map ourselves and see who knows the most standard direction and who draws the best.
Design intention: Students learn about the buildings in four directions on campus by observing the theme map of the sun rising in the east. Here, students are only required to draw the main buildings in four directions, mainly to remind students to indicate the direction of the building.
2. Let students collectively show and exchange their own recording methods in class, compare various methods and talk about how to draw more simply and clearly.
3. Summary: Maps are usually drawn from north to south, from left to west and from right to east. Instruct students to draw a schematic diagram in the usual way of drawing a map.
(5) Games
"I say you do it" game: all of you stand up and face south-nod, face west-clap your shoulders, face west-clap your hands, face east-twist your waist. (Do it in groups first, then in groups of four)
(6) Operation design
1. Complete the matching exercises of the classroom workbook.
2. determine the direction.
blackboard-writing design
Position and direction
North and South are opposite, and East and West are opposite.
North, south, west, east.
The library is on campus and the gymnasium is on campus.
The teaching building is on the _ _ side of the campus, and the gate is on the _ _ side of the campus.
