Mathematics teaching plan for large class: understanding the moving target of clock hour 1 △;
1, know the structure of the clock and the running rules of the minute hand and the hour hand, and learn to recognize the whole hour.
2, can be combined with the day's activity schedule dial hours, establish a preliminary concept of time.
△ Activity preparation:
Material preparation: 6 physical clocks, small alarm clock 1 each, self-made clock 1 each; Clock courseware
Experience preparation: put the small alarm clock into the partition material in advance to let the children observe freely;
The teacher reminds the children to watch the clock purposefully, and carries out various activities in combination with the daily activity arrangement.
△ Activity flow:
First, the teacher shows various physical alarm clocks as the owner of the watch shop, which leads to activities.
★ Ask children to tell the role of points in life.
"What if there is no zero point in our life?" It will remind us what time it is and what to do. )
Second, know the clock face and understand the structure of the clock.
1, guide children to find the same in each hour in a game sound.
"The first game is" Finding the Same "."They are different in shape, but they have something in common. " Children, can you find them? "
2. Use courseware to help children sort out their findings.
Courseware focus
1 Know the minute hand and the hour hand: Look at the clock. Just look at these two hands and you will know what time it is.
② Are the numbers of 12 on each clock the same?
Third, understand the operational relationship between the minute hand and the hour hand.
1, children operate the physical clock to understand the running relationship between the minute hand and the hour hand.
"The hour hand and the minute hand love sports as much as children. They run every day. Now they are all at the starting line of the number 12. Please guess who will win? Ok, the game is about to start, ready-let's go! "
★ "What do you see when the minute hand and the hour hand run? What secret did you find? "
2. Teachers use courseware to help children sort out and verify.
Sum up with the child: "The minute hand walks around and the hour hand walks one grid (number), which is one hour."
Fourth, show the "schedule of the hour" to guide children to observe and understand the hour.
1, "It's 7 o'clock sharp (10 o'clock,1point). What are the children doing? "
2. Guide the children to find that these three times have a common ground, and the minute hand points to the number 12.
3. Summarize with the children: ★ At the hour, the minute hand points to the number12;
★ When the minute hand points to 12 and the hour hand points to the number, what time is it?
4. Show the four clock faces again with courseware, so that children can identify the time.
Fifth, learn to set the clock.
Show three pictures in turn. Let the children look at the pictures and say the contents of the pictures. What time should it be (children go to kindergarten, take a nap and leave the garden after school)? Can you set aside this time? (Children dial with a small clock made by themselves)
Sixth, end the activity in a game tone.
I am very happy today, because our children have learned to look at their own watches and set the time. I hope that children can learn to watch and do things, so that they will not be late for school and will not procrastinate. They are good children who are punctual.
△ Activity extension:
1, continue to play physics hours for children to observe and explore.
2. "Draw cards and dial the clock" game
Two people have six picture cards, one person draws one from them, and draws the corresponding time on the Jason Chung surface according to the time on the back. If the cards are dialed correctly, he will put them away and the other person will continue to draw cards.
● Activity reflection:
It is clearly mentioned in the guide that only by observing children's needs and interpreting them can we really help them. For the children in the big class next semester, what we are concerned about is to do a good job of connecting children. From children's daily life activities, we observe that children are procrastinating and have a weak sense of time. At the same time, we also found these problems in communication with parents. I think this is also a problem of sexual orientation of urban and rural children. So in order to solve the children's sense of time and responsibility, I chose this trip to the countryside.
Mathematics teaching plan for large class: understanding the design background of clock hour 2 activity
Kindergarten mathematics is a systematic and logical subject with its own characteristics and laws. It is closely related to children's life, and mathematics activities are designed in combination with children's life reality and knowledge and experience. . Time without intuitive images is abstract, so I use the routine of children's familiar day activities to guide children to know the whole hour and half an hour, such as entering the garden at 8 o'clock and leaving the garden at 3: 30 ... This will easily lead to children's emotional experience and be understood and accepted by children.
moving target
1, understand the surface structure of clocks and watches, the movement and law of hands and minutes in time, and learn to watch hours and half hours.
2. Develop children's logical thinking ability.
3. Educate children to cherish time and develop good habits of working and sleeping on time.
4, like math activities, willing to participate in various arithmetic games, and cultivate rebellious thinking.
5. Guide children to be interested in numbers.
Teaching emphases and difficulties
Emphasis and difficulty: the understanding method of the whole point and the half point.
Activities to be prepared
1, solid wall clock, homemade big clock (rabbit on minute hand, turtle on hour hand).
2. Prepare a cardboard clock for each child.
Step 3 Courseware
Activity process
Section 1: Mobilize emotions and introduce topics (B2)
First, the teacher courseware demonstration: let students know all kinds of clocks and watches.
1, little friend, the teacher took you to the store to see what store you went to today. (watch shop)
Second, show the wall clock.
1, Question: What's its name? What other clocks are there at home (big clocks, small alarm clocks to remind us to get up early, so people call them watches for convenience)?
2. What is the function of the clock? The clock keeps moving, showing people the time, and people work, study and rest according to the time on the clock.
evaluate
After observation, students answer questions with their own life experience.
Part II: Exploring New Knowledge (A 18)
First of all, the teacher showed the homemade big wall clock.
1, please look at the shape of this clock (round), and what other clocks (square, frog, heart, etc.). ) Some children have seen it.
Let the children see what's on the clock. (There is a number of 1- 12 and two hands) The teacher explains that the number "12" on the clock is always above and "6" is always below, and teaches the children the names of "hour hand" and "minute hand".
Second, show the courseware to the children to help them know the shorter hour hand and the longer minute hand, and feel the operating rules of the hour hand and the minute hand.
Third, know the whole time.
1. Show the clock face at 3 o'clock and let the students know. Look at the clock face. Do you know what time it is? (at 3 o'clock)
how do you know
At 2 o'clock or 3 o'clock, what time does the minute hand point? What time does the hour hand point? The teacher posted the clock face at 3 o'clock on the blackboard.
3. The teacher shows the clock charts of 5 o'clock, 6 o'clock, 9 o'clock and 12 o'clock. Let the students talk.-What time is the minute hand? What time does the hour hand point? What time is it now? Then put the picture on the blackboard.
2, the characteristics of the whole period of time and the method of understanding the whole period of time.
Display courseware
These clocks all show the whole time. Let's see what they have in common. (Minutes all point to 12)
Teacher: Can you tell us how to watch the whole thing?
Health: The minute hand points to 12, and the hour hand points to what time. (like)
3, recognize the full time
The teacher quickly took out several different whole hours, and the students answered.
4, pull all the time
Pull out what the teacher or student said on the clock face.
5. Know half a point: Show the clock face with half a point, let students observe the position characteristics of the hour hand and the minute hand, and discuss in groups.
6. Group report: Ask the representatives of several groups to talk about the position characteristics of the hour hand and the minute hand in half an hour.
7. Teacher's summary: A few hours after the hour hand, the minute hand points to 6, which means what time is it?
evaluate
Observe carefully, think seriously, operate by hand and draw a conclusion.
The third quarter hands-on operation, try to practice (B7)
1. All children are required to mark all the time (get up at 7: 00 a.m., have class at 8: 30 a.m., have lunch at 12 p.m., finish school at 3: 30 p.m. and go to bed at 8: 00 p.m.) on the homemade cardboard clock face according to the above method. Teach children to do various activities according to time since childhood, cherish time, don't be late for school, and don't play on the road after school.
2. Patrol the classroom and help the children in difficulty.
3. Time collision (online): Please connect the time on the clock face with the time below with a line.
4. Summary: The minute hand points to 12 and the hour hand points to what time.
When the hour hand passes, the minute hand points to 6, which means what time is it?
5. Look at the pictures and talk about dogs and pigs. When and what are they doing? Why is it time for the pig to go to bed, and the homework has not been finished? Teach children to follow the timetable.
The fourth quarter to play games and consolidate new knowledge (B3)
Play the game "What time is it?" Let the children set the clock.
1, talk about the rules of the game: children dress up as lambs and dial the clock. When the teacher says when, the lamb rings the clock. Ask the old wolf to watch the clock. When the lamb rings the bell, it stops. When the wolf saw that the time was right, he stopped eating the lamb. When the time is wrong, he eats mutton.
2. Let the children use the clock as the steering wheel and drive out of the classroom to play games. (End of course)
evaluate
All the children operate independently according to the content of the courseware presented by the teacher, try to practice, choose the whole course and half time, and consolidate what they have learned in the game.
Section 5 [Extension after class]
Let the children go home and know the clock with their parents.
Teaching reflection
The day before the math activity "Know the clock", I asked the children to take the alarm clock at home to the kindergarten, so that they could understand and know the clock more intuitively. On the day of the activity, the children were so proud and devoted to playing with their alarm clocks, but from the final written operation results, the children's grasp of the situation was not ideal. Why is it not ideal to have materials that can be directly operated? After careful consideration, the following conclusions are drawn:
(a) Lack of previous experience. Although the children all brought alarm clocks, they all brought them on the day of the activity, and there was not enough time to effectively guide them to observe and understand. Children lack time to understand, discover and explore this new material.
(2) Too much stimulation during activities. In the activity, most children pay attention to their own alarm clocks, and then they care about whether there is anything new and special about other people's alarm clocks. It is difficult for children to concentrate all their attention on classroom teaching.
In view of the above two points, the following measures have been taken and achieved good results:
(1) Help children consolidate their understanding of one hour and half an hour in the form of games. The game "What time is it, Wolf?" It was changed to "What time is it for XX children and XX children?" Driven by the rhythmic game language, children's enthusiasm for participation is very high and the effect is good.
(2) Operation and production deepen the understanding of time and clock. A large number of clock faces, hour hands and minute hands are all prepared to make clocks for children. In the process of making, I have deepened my understanding of the whole point and the half point, and I can also explore and discover more secrets by myself.
(C) painting activities to increase the sense of competition. Let the children draw two clocks, the time above is the hour and half an hour respectively, and the specific time is determined by themselves. The requirements of the activity are: tell what you have been doing in these two hours and decorate the clock face beautifully. Finally, let's compare and see whose time is accurate and whose clock is beautiful, and decorate a "beautiful clock kingdom"
(4) Increase the operating materials related to the clock in the area, so that children with weak ability have the opportunity to continue to operate and consolidate, and choose freely, and children have no psychological burden.
Through the above remedial measures, the children in our class have a better understanding of clocks and watches, and also designed some beautiful clocks and watches, which enriched the regional materials and killed two birds with one stone.
