Verb (abbreviation of verb) activity flow:

(A) Introduction to the theme

Moderator: I ask you to think about a question. What is the longest, shortest, fastest and slowest in the world?

The student replied: It's time.

Moderator: Yes, this sentence was said by Gorky, and I appreciate it. In the eyes of people who don't cherish time, time is so slow; But in the eyes of people who cherish time, the opposite is true. They think that time is too short and days pass too fast. In fact, time is the fairest. It is given to everyone 24 hours a day, and time is the most precious. Only 1/3 of a person's life can really be spent studying, working and contributing to society. Mr. Lu Xun said: "Saving time will make a person's limited life more effective, which is equivalent to prolonging his life."

(B) exchange aphorisms and aphorisms

Moderator: At all times and in all countries, there are many people with lofty ideals who have a deep understanding of time. It is of great significance for our growth to guide our lives with these famous aphorisms that cherish time. Let's talk about the famous sayings you know about this.

Student exchange: The students said many famous sayings, the main contents are as follows.

Time is life, time is speed, and time is power-Lu Xun

"Time should be allocated accurately, so that every year, every month, every day and every hour has its special tasks. -Comenius "

"Time is like water in a sponge. As long as you are willing to squeeze, there is always something. -Lu Xun "

"People who give up time; Time will give him up. -Shakespeare "

"absolute beauty, a day is difficult. It's time for people to encourage themselves when they reach middle age. Time goes by and waits for no one. -Tao Yuanming "

"The more a person knows the value of time, the more he feels the pain of losing time. -Dante "

"I only regret one thing: the days are too short and pass too fast. A man can never see what he has done, only what he should have done ...-Madame Curie. "

Moderator: Please talk about your understanding of these aphorisms and try to create some of your own aphorisms.

(3) Situation analysis

Time is so precious, but we often encounter the following situations in our daily life:

(sketch performance)

1, several students published a blackboard newspaper without prior arrangement. Two groups of students are responsible for writing and drawing, one is idle, the other is grabbing territory.

2. A student does his homework at home, but eats for a while, reads newspapers for a while, and even writes while watching TV. As a result, he didn't finish it when he went to bed at night.

After school, several students discuss playing video games. The monitor asked them if they had finished their homework. They replied, "Homework? What is homework? Wait until you arrive at school early tomorrow morning to ensure that 10 minutes will be completed. "

Moderator: After the sketch performance, everyone analyzed and discussed "What did the three sketches show?" ? What inspiration did the students get from it? "

(D) the story of the role model

Moderator: A few students in the sketch just now unconsciously wasted a lot of time, which should be taken as a warning. In life. No matter revolutionaries, scientists of the older generation or outstanding young people of the present age, and many people around us are racing against time, studying hard and trying to climb the peak of science. Now, please follow the daily life scenes of several groups of characters I usually shoot and see how they seize the time and work hard. (The following contents are performed by several students and explained by the host. )

Lens 1: Mozart, a famous Austrian writer, even considered music creation when he had a haircut. He often can't help but stop his hairstyle and write down his own new music. He said, "whoever studies as hard as I do will be as successful as I am."

Lens 2: Einstein never wastes time even when he does housework, but finds time to think. Once, he took a walk on the road in Bern with a stroller. With heavy steps, he stopped every ten steps, took out a pencil and paper from his coat pocket, wrote down a few lines of numbers and formulas, looked down at his sleepy son, looked up at the clock in the bell tower, and walked forward again. ...

Scene 3: In order to save reading time, President Mao Zedong keeps books that can be read at any time in the toilet and bedroom.

Lens 4: Bus stop. My classmate is waiting for the bus. They are reciting English with cards.

Moderator: Please talk about your thoughts on learning the deeds of celebrities. (communicate in groups first, then communicate with the whole class)

(5) Exchange experience

Moderator: Through the exchange and performance just now, everyone understands that we should cherish time, but what should we do? We invited several students to talk about how they usually seize the time.

Student 1: Every time the students in our propaganda group publish a blackboard newspaper, they always design the layout first, and then the students in charge of writing write on the left, and the students in charge of drawing draw on the right, and then exchange, which saves a lot of time.

Student 2: As the secretary of the Youth League branch, I have a lot of work, so I will write down what I will do tomorrow in advance, and then arrange all the work according to the importance.

Moderator: The experience of these two students tells us: "Plan ahead and arrange time scientifically".

Student 3: After I go home every day, I always review my lessons and do my homework first, and then go out to play or watch TV with my classmates.

Student 4: Last week, it was my grandfather's birthday, and I was going to his house to celebrate, so I took the time to finish my homework as soon as I got home.

Compere: The experiences of these two students tell us that "seize the day".

Student 5: When I help my mother with housework at home, I always listen to English recordings while working. I also get up in the morning to listen to English recordings and wash before going to bed at night.

Moderator: After listening to other people's reluctant examples, please write down your feelings, sentiments and what you plan to do in the future, and communicate in class.

Moderator: This tells us to "make good use of sporadic time". It seems that it is not difficult to waste time. The key is to plan ahead and arrange time scientifically. Seize every minute and make good use of the scattered time.

Please make a daily life schedule according to your actual situation after class.

(6) the end

Moderator: Finally, let's sing the campus song of Taiwan Province Province-childhood.

(All the students sing together)

"Under the banyan tree by the pond, cicadas cry in the sound of summer ... it is always after school that they know that they have done some homework, and they always have to wait until the exam to know that they have not read the books they should read ... an inch of time and an inch of gold are hard to buy ..."

Sixth, feedback:

1, the students made a daily life schedule.

2. This class meeting has become a guide stone for the exchange and discussion of the content of the lesson "Traveling to the Kingdom of Time". After class, the students had a series of discussions, such as:

(1) Make a study plan according to the biological clock of the brain. The best time for brain function is 10- 1 1, 2-4 pm and 8-9 pm.

(2) exchange learning methods and skills, and explore how to improve learning efficiency to achieve twice the result with half the effort.

Lesson plan 2:

Teaching plan of "knowing time" in the third volume of primary school mathematics

Analysis textbook:

The arrangement of the teaching content of Knowing Time is to read the time with the method of 5 minutes and 5 minutes. Through practical operation, it is known that 1 is 60 points. According to the contents of the first volume of senior one, the understanding of time in the teaching materials is arranged in the order from special to general and from simple to complex, which conforms to children's cognitive laws and people's experience and habits of reading time through watches.

Analyze students:

The teaching of "knowing time" is based on the learning of "knowing clocks" by the students in the first volume of senior one. Through previous study, I have mastered some knowledge of clocks and time, such as knowing that there are hour hands and minute hands on the clock face; A number with 12; There are 12 large communities and 60 small communities. , and mastered how to look at the hour and half a hour. I believe that students will not find it difficult to master the content of this lesson.

Design concept:

The teaching design of this lesson has the following characteristics:

First, the presentation of knowledge is combined with real life.

Because time is a very abstract concept, we should pay attention to combining life practice in teaching, so that students can better understand time by using their own life experience. For example, in the introduction of the topic, the time of the second class (9: 00) is used, which is what the students have mastered. Five minutes later, that is, (9: 05), this time is what the students will learn in this class, so the new lesson is introduced well. Finally, the class is over at 9: 40, which makes the teaching more complete.

Second, present knowledge intuitively.

In the teaching, multimedia visual demonstration is used, and by looking at the shadow on the clock face, the time is read out in 5 minutes and 5 seconds, which has achieved good teaching effect. When teaching 1 =60 minutes, let the students set their own clocks. Through intuitive physical operation, the relationship between time and minutes can be seen at a glance.

Teaching content:

Compulsory education curriculum standard textbook page 865438 +0, such as 1 and "doing" questions 1, exercises 15 questions 1 and 2.

Teaching objectives:

1, when will students read and write?

2. Let the students know that 1 =60 points.

3. Cultivate students' awareness and habit of cherishing time.

Teaching emphases and difficulties:

Ask the students to finish reading and writing in a few minutes until 1 =60.

Teaching aid preparation:

Multimedia courseware, physical clock, small alarm clock prepared by students.

Teaching process:

First, create situations and introduce new lessons.

1, create a situation.

(Let the bell ring)

Teacher: Students. ...

Teacher: Who said, what class is it now? Do you know when the second class starts in our school? Ask questions and show the courseware, which shows a clock face fixed at 9 o'clock.

2. Review old knowledge.

Teacher: How do you know the time on the clock is 9 o'clock? (The hour hand points to 12, and the minute hand points to 9, which is 9 o'clock. )

3. Introduce new courses.

(About 5 minutes later, the clock on the screen shows 9: 05. )

Teacher: Students, do you know what time it is?

Teacher: Today, teachers and classmates come to know the time. (blackboard writing topic)

Second, intuitive demonstration, exploring new knowledge

(A) know the clock face

1, Teacher: Through last semester's study, we know what is on the clock face.

2. Let students discuss, communicate and complement each other in the study group.

3. Students feedback the communication results, and teachers demonstrate with courseware. (There are an hour hand, a minute hand, 12 numbers, 12 large cells, each with 5 small cells, a * * *, and 60 small cells. )

(2) Know the time.

1. Recognition score.

(l) Guide students to observe the minute hand. (An enlarged clock face is displayed on the screen, indicating that the minute hand walks in 1 square. )

Teacher: The minute hand is used to indicate "minutes", and the time for the minute hand to walk 1 is 1 minute.

(2) Ask questions during the courseware demonstration:

① What is the minute hand pointing to 1? Why? A big cell has five small cells, so it is 5 points. )

② What is the minute hand pointing to 4? Why?

③ What is the minute hand pointing to 7? Why?

……

2. Know the time.

(1) Teaching Example 1 First Clock Face

Teacher: What does the hour hand point to? What time? What does the minute hand mean? What is the score? (The hour hand points to a little more than 3, and when it is 3, the minute hand points to 1, which is 5 points. )

Teacher: What time does the clock show? (3: 05)

(2) Two representations of teaching time. (Two expressions were learned last semester. Remind students to add a "0" after 2 o'clock when writing at 3: 05, such as "3: 05")

(3) Teach the second and third clock faces in the same way.

3. Understand the relationship between time and minutes.

(1) student grouping operation.

Ask the students to take out their own small alarm clock, dial it, watch the minute hand turn around and the hour hand walk a few squares, and exchange their operation results in the group.

(2) Students feedback the communication results.

Student feedback, the teacher shows the courseware: the minute hand walks around and the hour hand walks a big grid.

(3) resulting in "1 =60 points".

Teacher: How many minutes does it take for the minute hand to walk around? (60 minutes) How long does it take to walk a big grid clockwise? (at 1)

Teacher: Through the students' operation, we know: 1 hour =60 minutes (blackboard writing).

(3) Practice and consolidate new knowledge.

1. The teacher dials the clock and the students tell the time.

2. Two students are in a group. One student dials the clock and the other says the time.

The teacher said the time and the students set the clock.

Third, apply new knowledge to solve problems.

1, complete the textbook "Do it" 1.

When students practice, first say: What time does the hour hand point to? What does the minute hand mean? What is the score? Then write the time on the bottom of each clock face.

2. Complete the exercise 15, question 1.

Let the students say how many marks correspond to the scale of each grid, then say what the students are doing in the first picture and when to read it, and then record it in two ways.

After the students finish, work in pairs, tell each other what the daily schedule is, and set aside time with a small alarm clock while chatting. Finally, let some students who speak well talk about it and educate students to have the consciousness and habit of cherishing time.

3. Exercise 15, question 2.

Ask the students to read the time on the clock before connecting.

Four. abstract

Teacher: Students, what did you learn today?

As soon as the bell rang, the clock on the screen showed 9: 40.

Teacher: Can you tell us when to finish the second class?

Lesson plan 3:

Understanding time

Teaching content: the content of Math 8 1 page, the standard experimental textbook of compulsory education curriculum (below grade one), the 1 problem of exercise 15 and supplementary exercises.

Teaching purpose:

1. 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 progress 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 once.

The media demonstrated the process from 12 to 1. Question: How many minutes did the minute hand go from 12 to 1? what do you think? (From 12 to 1, there are five squares, and the minute hand walks 1 minute, and the time for walking five squares is 5 minutes. )

Inspire students to ask questions: What is the minute hand of 12 to 2? what do you think? What is the minute hand of 12 to 4,9, 1 1? How much is a minute hand walking around?

Summary: It takes 1 minute for the minute hand to walk once in 1 grid, and it takes several minutes to walk several grids.

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?

Each group recommends two people to 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 points. )

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 points should occupy two positions, and those less than 10 points should be occupied by 0. For example, at 9: 05, if it is less than 10, we will write 0 first and 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 the first question of exercise 15.

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 so delicious that people can't help drooling, 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!

Lesson plan 4:

Year, month and day

Teaching content: The Mathematics Textbook for Nine-year Compulsory Education for Six-year Primary Schools, Volume VI, page 8 1-83, page 83 "Do one thing" and exercise 18, question 5.

Teaching objectives

First, let students know the time unit year, month and day; Know the knowledge of big month, small month, flat year and leap year; Remember every month and the number of days in a flat year and a leap year.

Second, enable students to judge whether a year is a normal year or a leap year.

Third, help students initially establish the concept of time such as year, month and day, cultivate students' observation ability and thinking ability, and infiltrate scientific thinking methods.

Fourthly, the ideological education of patriotism and cherishing time should be infiltrated.

Teaching emphases and difficulties

Key point: understanding of the number of days in each month. (Remember the number of days in twelve months correctly and quickly))

Difficulty: the judgment of normal year and leap year.

Prepare teaching AIDS and learning tools:

Teaching AIDS: projector, slide show, 1993 calendar, 2000 1989 calendar.

Learning tools: each person prepares an almanac card for recent years.

Teaching process:

First of all, inspiration imports.

Students, we have a solemn flag-raising ceremony every morning. Whenever I see the bright five-star red flag raised in Ran Ran, I feel very excited. Do you know when our motherland was founded? (1 949 65438+1October1) 65438+1October1is the birthday of our motherland. Do you know your birthday? (know)

These are all time units expressed in years, months and days. Besides the hours, minutes and seconds we know, there are also the years, months and days we are going to study today. (Board theme)

Second, the new lesson

1, know the calendar

This is an almanac of 1993. There is a lot of knowledge about "year, month and day" in this almanac. Please look for the answer to the question from the yearbook.

How many months are there in a year? Are the days the same every month? There are several situations.

3 1 day is how many months in a year? Which months are 30 days? How many days are there in February?

Note: We call the month of 3 1 day big month, the month of 30 days small month, and February is a special month. How many big months are there in a year? How many miscarriages?

2. Remember the big moon and the small moon.

What month is 3 1 day? Which month is 30 days? How to remember the big month and the small month of a year?

(1) Remember the size and month of the left fist.

The textbook introduces a good method of counting left fists. How to calculate? Please open page 82 of the book and read the following paragraph: "Know how many days there are in a month" (the teacher organizes and guides the number of students while reading). Show the left fist by projection, point to the left fist and count with the students.

Consolidation question: How many days are there in each month? How many days are there in a month? Except which month?

(2) Children's songs record the month.

One, three, five, seven, eight, ten, wax, 31 days never breaks.

Lead students to read children's songs.

Exercise: Children's Day, Teacher's Day and Labor Day. Are these festivals in the big month or the small month?

3. Know the normal year and leap year.

We know the number of days per month of 1993, so are the number of days per month in other years the same? Students can clearly see that no matter what year, there are 1989-2000 months every year.

Question: Are there any changes in the number of days in January in different years? What about other months?

Summary: In 12 months every year, there are 7 big months and 4 small months. The number of days in February varies with the year. We call a year with 28 days in February a flat year and a year with 29 days in February a leap year.

Question: The number of days in February can help us understand the normal year and leap year. How to judge whether a year is a normal year or a leap year? Please see the table below. What year is a normal year? Which year is a leap year? What rules are found according to the year? Let students understand that it is usually a leap of four years.

What is the relationship between the Gregorian calendar year of leap year and 4? Ask the students to divide the years from 1989 to 1994 by 4 and see what laws are found. (Gregorian calendar year is a multiple of 4, which is the general law of leap years)

Exercise: 1949
