Teaching purpose:

Knowledge goal: Make students read and write the clock time correctly, know that 1 is 60 minutes, and initially establish the concept of time.

2. Ability goal: cultivate students' good habits of observing things carefully and being good at thinking.

3. Moral education goal: educate students to cherish time, develop good study and life habits, and further improve their consciousness and enthusiasm of grasping time and studying diligently.

Teaching emphasis: knowing the speed of hours and minutes, you can correctly read and write the time indicated on the clock face.

Teaching difficulty: reading the time indicated on the clock face.

Teaching preparation: multimedia courseware, physical projector, various fruit clocks, etc.

Teaching process:

First, the introduction of new courses.

1. The concept of time is introduced into the riddle.

I have a good friend who keeps walking and tells me to study and rest. He is really my good helper. What is this?

What can the clock tell us? (time. Can you tell me when and what you do?

2. Import the theme map.

The teacher asked the students to tell what the picture was and what time was displayed on the clock. The camera reveals the theme.

Second, new funding.

1. Know the clock face.

The media showed the clock face, and the teacher asked: What's on the clock face? (12 number, hour hand, minute hand, grid. )

How many squares are there on the clock face? (Dynamic demonstration: 12 numbers divide the clock face into 12 big squares. )

How many cells are there in each big cell? (Dynamic demonstration: each large cell has 5 small cells. )

There are five cells from 12 to 1. How many cells are there in 12 to 2? what do you think? 12 to 3?

Do you know the number of cells corresponding to each number? Students in the same seat discuss it first, then open the textbook 8 1 and fill in the corresponding figures in brackets.

After filling in, check the answers by multimedia. Do you know how many squares there are on the clock face? (60.)

2. When you know each other.

Media presentation: the hour hand flashes, and the hour hand changes from the number 12 to the number 1. When the clock went 1, the elapsed time was 1.

Heuristic question: The clockwise is from 1 to 2: 00 1 hour. How long is it from 4 to 1 hour? Can you tell me that when the clock goes, it is also 1 hour?

It is concluded that the time that an hour hand passes from one number to the next is 1.

3. Know the score.

Media presentation: The minute hand flashes, moving from 12 to 1. It takes 1 minute for the minute hand to walk in the 1 square.

The media demonstrated the process of moving the minute hand from 12 to 1. Question: How many minutes did it take for the minute hand to move from 12 to 1? what do you think? (There are five squares from 12 to 1. The minute hand needs 1 minute, and the time to walk five squares is five minutes. )

Ask the students: How many minutes does it take for the minute hand to walk from 12 to 2? what do you think? How many minutes does the minute hand walk from 12 to 4, 9, 1 1? How many minutes does it take for the minute hand to walk around?

Summary: The minute hand needs 1 minute, and the minute hand needs several minutes.

Step 4 feel it.

Computer timing, students work in groups. Group 1: Read the text; The second group: writing; The third group: oral calculation; The fourth group: counting.

A minute later, ask: A. How many words do you read a minute? (Read a text in chorus) B. How many words do you write a minute? (unified copying) C. How many oral calculations do you do a minute? (Pre-printed questions) D. How many do you count a minute?

Two people in each group report.

5. Reading and writing time.

The media shows the clock face, and sometimes the hour hand does not completely point to the time. For example, now the hour hand is not pointing to 9, but a little past, indicating that the time is more than 9 o'clock. So, how much is it? It depends on the minute hand: now the minute hand has changed from 12 to 1. How many points did the minute hand go? (5 minutes. )

Therefore, the time now is 9: 05. There are two ways to express it. One way is to express it in Chinese. The second one, like an electronic watch, has two points to separate left time and right time. Write a few words when you have time, then make two dots and write the dots on the right. It should be noted that the minutes should occupy two digits, and those less than 10 minutes should be occupied by 0. For example, 9: 05, less than 10 minutes, let's write 0 first, then 5. (Write it on the blackboard. )

Show the second clock face. Can you read and write the time on the clock? How did you come up with it? Discuss with each other in groups of four.

After the discussion, the students reported.

Teachers and students agree on the method of summarizing reading time: reading a time should be determined according to the position of the hour hand and the minute hand. Look at how long the hour hand has just passed, and then look at how many squares the minute hand has gone from 12, that is, a few minutes. The time on this clock is a few minutes.

6. Time-sharing relationship.

The media showed the clock face. What time does the hour hand point and the minute hand point? (The minute hand and the hour hand coincide and both point to 12, that is, 12. )

Watch it again carefully (media demonstration). How do the minute hand and hour hand move? Discuss at the same table. Minute and time walk at the same time, in the same direction and at different speeds. The hour hand turns from 12 to 12 and 1, and the hour hand turns half a grid. At the same time, the minute hand turned from 12 to 6, which means that the minute hand turned half of the whole clock face. )

What time does the clock show? (12: 30, 12: 30. The media will demonstrate again how the hour hand and the minute hand move now. Discuss with each other in groups of four. (The hour hand reaches the number 1 and the minute hand reaches the number 12. The hour hand made a big turn, and the minute hand only made a turn. )

What does this mean? (1 =60 points. )

7. summary.

Children, please remember: there are twelve numbers on the clock, five squares between the two words, and sixty squares in a circle. When the word "1" is 1, the minute hand is 1. 1 hour =60 minutes, and 60 minutes is an hour. When the hour hand just passes the number, it means it's time. If you want to ask how many points you got, please look at the minute hand carefully.

Third, consolidate the practice.

1. Do exercises 15 1 questions.

Will you look at the clock the way you learned today? This is a timetable for children. Let's have a look.

Xiao Fang appeared. Voiceover: Hello, I'm your good friend Xiao Fang. I am a primary school student now, and I want to learn to live independently. Since I learned to watch the clock, my life has been arranged in a much more orderly way. Can you tell me when and what I will do?

This is your good friend Xiao Fang's problem. Can you answer that? Let's listen to Xiao Fang.

Voice-over: (ringing) The alarm clock is ringing. Get up quickly, or you will be late for school. I have to brush my teeth first to see what time it is. ?

Do you know what time it is? How do you know that? (7: 05.)

Schreiber: After breakfast, I'm going to school. Goodbye to mom and dad. The sun is shining in the sky, flowers smile at me, and birds say early. Why are you carrying a small schoolbag? The second class in the morning is math. Children, do you know when I have math class? (9: 30.)

Look, everyone, how hard your good friend Xiao Fang works in class. I hope you can be like her.

Voice-over: After dinner, I want to relax and watch cartoons (music). Do you know when I watch cartoons? (6: 40.)

Xiao Fang finished watching this cartoon. Let's see how she does it again.

Schreiber: It's getting late. I'm going to bed. If I can't sleep well, I won't have the spirit to go to class. Students, do you know when Xiao Fang goes to bed? (8: 35.)

It seems that everyone can read the time. Can you write the time? Please write down Xiao Fang's schedule in two ways.

After writing, correct it collectively.

This is Xiao Fang's daily schedule, and there will be a lot of gains on such a day. I hope all the students can arrange their time reasonably and be the little masters of time.

2. Find seats for small animals.

Everyone did a good job today. The teacher has good news for you. There will be a get-together in the forest park, but the small animals haven't found their place yet. Please help the students find it and ask the little animal to spend the same time in his seat.

Media presentation: Please give the animal a seat corresponding to the time on the animal and the time on the chair. Such as 4:25=4: 25. Why hasn't the squirrel sat down yet? Give it a chair and ask a classmate to write down its time.

3. "eat fruit" and recognize the time.

The little squirrel is very happy. It was our children who helped him. The little squirrel brought some fruit to thank everyone. There are apples, pears, bananas, watermelons and strawberries ... they are delicious and make people drool, but they just want to give the fruit to the children who behave well. If you can see the time on the clock clearly, I will give it to you.

Show all kinds of fruit clocks by projection. Please recognize the time.

Fourth, music reading.

In the beautiful lyrical music, the recitation sounded.

The media showed a picture worth one minute. "The most precious thing in the world is time. An inch of time is an inch of gold, and an inch of gold is hard to spend. " You see how much wealth can be created in one minute, how many things can be done, and how much time is valuable! Children, time is life for you! Time is speed! Time is power! Time is all the wealth that human beings possess. I hope you cherish every minute, read today's books well and become tomorrow's talents!
