Teaching Design of the Open Class of "Knowing Clock" for Grade One

Teaching design 1 teaching objectives of the first-year open class "Knowing Clocks";

1, combined with life experience, I have a preliminary understanding of the clock face and can recognize full-time and half-time.

2. Under certain circumstances, gradually develop the concept of cherishing time and the good habit of arranging time reasonably.

Teaching focus:

Learn to look at full-time and half-time according to the reality of your life.

Teaching difficulties:

Know that the minute hand and the hour hand are in the direction of the whole hour and a half.

Teaching process:

First, dialogue import

Do children like making friends? Today, Teacher Qu invited a new friend Xiaoming to study math with us. Are you happy? (pictured) Xiao Ming also brought gifts for everyone. You want to know what it is? Look, it's coming. Let's guess who it is. (Showing the courseware clock face) Have you all seen the clock? Where have you seen it? What a considerate boy, he knows to pay attention to things around him.

What do you know about clocks?

Second, know the clock face.

1, look at the clock face

Teacher: Please gently take out your small alarm clock and observe what is on the clock face first. Then tell your findings to the children at the same table and compare which little teacher is the most qualified.

Classroom communication

Health 1: I see the number.

Teacher: What are these numbers? ( 1—— 12)。 Take out your hand and point when reading. Can you draw the direction you just pointed? Name the children and show them. (Point out: We can call the direction that the child just indicated with his hand clockwise) Have you found anything new about these figures?

Health 2: 12 is above, 6 is below, 9 is on the left, and 3 is on the right.

Teacher: Close your eyes and think about the position of these four numbers. When you think about it, let's play the game "I say you order". The teacher said nine students pointed to the left, said the left, the teacher said the bottom, and the students said 6 (great boy! It seems that we have studied the numbers on the clock face. ) What do you see besides counting?

2. Understanding of hour hand and minute hand

Health: long needle, short needle.

Teacher: Do you know the names of these two (three) needles? (hour hand, minute hand and second hand). how do you know You are good at acquiring knowledge from life, and you are a good boy who knows how to learn. Can you find the hour hand and minute hand from the clock model? Tell it to your deskmate. (Little teachers know a lot, some can not only look at the time on the clock, but also know that there are 12 numbers and three hands on the clock face ...)

Step 3 make a clock face

Teacher: The children's eyes are so bright that they find so much knowledge on the clock face. Yesterday, the teacher tried to make a clock face, but only drew a disc. Can you help me finish this clock face? Who wants to try it in front? Other students draw their own clocks.

Teacher: The child is really capable. It seems that you are all studying hard on the clock face. Children, Xiao Ming is a good boy who studies as hard as you. He knows how to arrange his day. Do you want to know how Xiaoming arranges his life and study time reasonably? Then let's take a quick look at Xiaoming's day! (Page 90)

Third, the exchange theme map

1. Watch the chart carefully.

What does Xiaoming do at what time? Read it first and say it yourself. Then tell your deskmate.

2, the whole class communication

(Find a student and make it clear. In real life, we are used to saying "6: 07: 30", while in the kingdom of mathematics, the standard saying is "6: 07: 30" (it is simple and clear, and the time is very accurate).

Now the teacher will ask these six clocks (show pictures).

Fourth, know the hour and the half hour.

1. Pick a time, pull it out on your clock face model and tell me how you recognize it. Tell your classmates how you know the time. Pay attention to what others say when communicating? If you have different opinions, wait until the students finish.

At 6 o'clock, the hour hand points to 6 minutes, pointing to12; At 7: 30, the hour hand points to 7-8 and the minute hand points to 6. How clearly you speak shows that you are a good boy who is good at observing and finding problems.

2. What's the difference between full time and half time?

Health: (the hour hand points to 12, and the half-hour hand points to 6. )

Teacher: What a clever boy. He speaks very well.

Verb (abbreviation for verb) consolidation exercise

Pull time:

Teacher: After learning so much, let's relax. Play a little game. See who has the sharpest ears and the most dexterous hands, and take out the clock face model.

1, the teacher said time, birth, exit.

2, students say that time is pulled out collectively. This is not right. Who wants to help him?

Can you teach me how to tell the time? )

Reward each of you with the opportunity to talk with your classmates at two favorite times. What are you doing at this time? Xiao Ming also likes watching cartoons to see what Xiao Ming does at other times. Do the exercises on page 9 1 in the book.

Teacher: Do you think Xiao Ming's schedule is reasonable? Why? What do you think of seeing Xiao Ming arrange his study and life in an orderly way?

Student: Like Xiao Ming, arrange your time reasonably.

Second, find friends.

Can you help the clock find a friend? (Book 9 1 page 2 questions)

Third, the whole class competition, grab the answer time

Teacher: Divide into two teams. One team recognizes the whole hour and the other team recognizes the half hour. According to the time shown by the teacher. Two groups of students stand up and say it out loud.

Teacher: How important time is. So many famous sayings about time have been handed down from ancient times to the present. Tell your classmates if it's weird.

Broaden your horizons: What other clocks and watches have you seen? (showing pictures)

Abstract of intransitive verbs

What do you think you have learned here?

It seems that the students have really learned a lot of knowledge. (Play the recording) I hope that, as the song says, you young trees will thrive in time and grow into towering trees under the witness of the old people.

The teaching design of the first grade open class "Knowing Clocks" Part II Teaching Content;

People's education publishing house, the first volume of mathematics in the first grade of primary school, pages 84-87.

Teaching material analysis:

This lesson mainly talks about students' understanding of the theme of the whole period of time. In this case, the teaching material arranges time according to children's habits of life and study, so that students can know the clock face. There are two purposes to compile this part: first, combining students' existing life experience, let students learn to watch the clock and know the hour; Second, according to students' age characteristics, properly infiltrate the education of cherishing time, so that students can initially form the habit of doing what at what time.

Analysis of learning situation:

For modern first-grade primary school students, before entering school, they have accumulated experience in watching the time on the clock (now basically every family has a clock, and the display of a large number of TV programs has played a subtle role). Therefore, in teaching, clocks and the whole time should not be taught as "brand-new" knowledge. Therefore, the teaching of this course will fully mobilize students' existing experience, combine students' real life, and use learning tools to strengthen observation, comparison and operation activities.

Teaching objectives:

1, get to know the clock face, and know the numbers on the hour hand, minute hand and clock face; Learn to look at the whole time with life experience and know two expressions of the whole time.

2, through observation, operation, communication and other activities, develop students' mathematical thinking ability, cultivate students' awareness of inquiry and cooperative learning, and experience the fun of learning mathematics.

3. Initially establish the concept of time, and consciously form a good habit of observing and cherishing time and arranging time reasonably.

Teaching focus:

Know the clock and read the whole time correctly.

Teaching difficulties:

Initially establish the concept of time, will look at the time on the clock.

Teaching preparation:

Multimedia courseware, physical alarm clock, electronic clock, two-pin non-linked teacher demonstration clock, two-pin non-linked student clock.

Teaching process:

First, create a situation to stimulate interest:

Talk: Children, we have made many digital friends. Today these digital friends will come to study with us again. Do you welcome them?

Show the scale of 12 and some numbers on the scale 1 2, (), 4, 5, (), 7, 8, (), 10,1() on the clock face, and students can finish it.

Q: Do children think this picture is a little familiar? Have you ever seen it in your life?

(Yes, it is the face of the alarm clock. )

Q: But what seems to be missing compared with the clock face we have seen?

The courseware shows all kinds of clocks and watches.

Teacher: Then let's take out the pointer, too!

Secret topic: big knowledge of small alarm clock. Let's get to know the clock today! (blackboard writing: know the clock. )

Second, explore new knowledge with experience.

1, perception clock face:

Q: What is the clock we see now?

Communication: 12 number, (12 big square), 2 pointers (some students may say that there are three pointers, and the teacher pointed out: today we will wronged the second-hand brother and will not study it for the time being).

Q: Do you know the names of these two kinds of needles?

The long one is the minute hand and the short one is the hour hand.

Short hour hand)

2, understand the whole time:

Dialogue: The two brothers, the hour hand and the minute hand, kept running on the clock face, letting us know the time. They have good skills. Listen to them. ...

(Animation shows Xiaohong getting up)

Q: What did you know in the animation just now? Where did you know that?

(Xiaohong gets up at 7 o'clock. The clock on the wall, the electronic clock on the desk and Xiaohong's mother all told us. )

Teacher: 7 o'clock is called 7 o'clock in mathematics. Can you tell me what the hour hand and minute hand point to at 7 o'clock?

(The hour hand points to 7 and the minute hand points to 12. )

Wall clocks at eight o'clock, three o'clock and six o'clock. Q: Do you know what time it is?

Talk about how many points the hour hand and the minute hand point to. What time?

Discussion: Look at the clock face above. What did you find?

Communication: Their minute hands all point to 12, and their hour hands point to 8 at 8 o'clock, 3 at 3 o'clock and 6 at 6 o'clock.

Say: The 7 o'clock, 8 o'clock, 3 o'clock and 6 o'clock you just saw are all called the hour. (blackboard writing: exactly) What time does the minute hand on the clock face point to 12 and the hour hand point to? (blackboard writing: long minute hand refers to 12, and short hour hand refers to what time. )

Feedback exercise: ① When the teacher dials the whole hour on the clock face, what time does the student say?

(2) The teacher talked for a whole hour, and the students set aside this time on the clock.

(3) One deskmate said the whole time, and one set aside the whole time.

Teacher: It's very kind of children. They quickly learned to recognize and read the whole time. Do you know how the electronic clock shows at eight o'clock, three o'clock and six o'clock?

Communication: 8 o'clock, 3 o'clock and 6 o'clock respectively. The corresponding electronic clock is displayed in the courseware. )

Summary: There are two ways to express the whole time: the first way is to use the word "number" plus the word "time" and write it several times. Such as: 7 o'clock, 8 o'clock, 3 o'clock, 6 o'clock. The second is to add a colon to the number and then write two zeros. Such as: 7 o'clock, 8 o'clock, 3 o'clock and 6 o'clock just now. (This is usually expressed on an electronic clock. )

3. Exercise in class.

Third, use knowledge to solve problems:

1, the courseware shows Xiao Ming's day. Please write down the time when Xiao Ming did these things.

Discussion: Is Xiao Ming's day arrangement reasonable?

Teacher: Yes, we should learn from Xiaoming, don't sleep late, make reasonable arrangements and be healthy and smart children.

Q: What is Xiaoming doing at nine o'clock?

(Reading, sleeping) Why are there two 9 o'clock?

(One is at nine o'clock in the morning and the other is at nine o'clock in the evening.) After the students answered, the teacher said, "Grandpa Clocks walked with Grandpa Sun during the day, and there was a whole hour in it at nine o'clock in the evening. It was 9 am and 9 pm during the day. "

2. Finish the exercises in the textbook 19 1 to 4.

Fourth, class summary.

The students did really well! Time is precious. Knowing how to cherish time and make full use of every minute of the day is a good boy. You see, in a blink of an eye, our class is almost over. What did you gain from this class?

The teaching design of the first grade open class "Knowing Clocks" Part III Teaching Objectives:

1, will recognize, read the whole process;

2. The whole time can be expressed in two ways;

3. Guide students to know time, and help children to develop good habits of cherishing and observing time from childhood.

Instructional design:

Although students are only in the first grade, they have accumulated some experience in knowing clocks and watches in their lives. When teaching on the hour, first let the students know the clock face, distinguish the minute hand from the hour hand, and compare and observe "what are the similarities among the three clock faces (6: 00, 8: 00 and 4: 00)" through discussion and exchange among the students, and get the conclusion that when the minute hand points to 12, the hour hand. Strengthen the understanding of the whole time, connect with life, show electronic representation, make students master two ways to express the whole time through practice, and finally show Xiaoming's daily schedule, thus infiltrating students into learning to arrange time reasonably and forming a good habit of observing and cherishing time.

Teaching process:

1. Description: Today is the first time for all students in Class One to come to the multimedia classroom. Are you happy? The teacher is very happy. There are so many teachers watching the children in our class one at the back to see who is the best.

Topic introduction: well, everyone is sitting so upright, so the teacher will give you a gift. Guess: A good friend can walk without legs and talk without mouth. He will tell us when to get up and when to go to bed. Question: Tell me where you have seen clocks and watches.

Summary: You have seen clocks and watches in so many places. Clocks and watches can be seen everywhere in your life. How clever you are! What can the clock tell us? Tell us when to start class, when to finish school and when to eat and sleep. How useful! This lesson: Let's learn the clock and write "Learn the clock" on the blackboard.

Second, new funding.

1. Look, the teacher brought a clock. Look at this clock carefully. What's on the clock face?

There are 12 numbers of minute hand (long) and hour hand (short) on the blackboard. Let's read it.

2. Take out the clock in your hand and point to the other person at the same table. That's an hour hand and that's a minute hand.

3. Then we know the clock face. Put it down first. Next, let's take a look. When does Lili get up every day? Do you know the time on the clock?

Summary: We often talk about 7 o'clock in life, but in teaching, 7 o'clock is called 7 o'clock. When we carefully observe 7 o'clock, what do the hour hand and the minute hand point to respectively? Well said, the minute hand points to 12, and the hour hand points to 7, which is 7 o'clock.

Do you know what time this clock is? What do the minute hand and the hour hand refer to?

5. What are the similarities between these points and hands?

Summary: The minute hand points to 12 and the hour hand points to (6, 4, 8). So, when the minute hand points to 12, what time does the hour hand point to?

Since everyone knows all the time, the teacher will test you. Dare to accept the challenge?

(1: 00, 5: 00, 7: 00, 8: 00) That's a good answer. When the teacher says the time, dial it yourself. Sit at the same table, tell each other the time and dial it.

We just learned to record the whole time in Chinese, so do you know another way to express the whole time? Show the courseware "12: 00". Do you know what time it is? Where have you met? (On the mobile phone, on the watch, on the ticket ...) So, let's take a look at 7 o'clock. How to express it electronically? Write 7 first, then write two dots side by side at the lower right of 7, and then write two zeros. They all read at seven o'clock and seven o'clock.

Third, practice.

When we know the time, we should arrange it reasonably. Let's see how Xiao Ming arranges his time.

Fourth, summary:

What have we learned today? What a great harvest! Then we should arrange our time reasonably like Xiaoming, and be a good boy who cherishes and observes time!
