Activity objectives:
1, learn more about the clock, recognize the whole hour and half hour on the clock, arrange the time reasonably, and try to do a good job of the clock.
2. Cultivate children's ability to recognize numbers.
Activity preparation:
Teaching AIDS: self-made courseware; Clock for demonstration.
Learning tools: the first group and the second group: material paper for "looking at pictures"; Three or four groups: clock face, hour hand, minute hand, thumbtack and plasticine; Group five or six: "look at the time card and draw the pointer" material paper; The child has an operating model clock in his hand. Time card.
Activity flow:
1. Riddle puzzles to stimulate interest
Mystery: "You can say that you can walk without a mouth and legs, and it will tell you when to get up and when to go to bed" (answer: clock) (show the physical clock)
2. Master the main structure of the clock face.
(1) Watch the clock
Through observation activities, guide children to compare the difference between the hour hand and the minute hand on clocks and watches, and understand the number 12 and its arrangement position.
The teacher asked: 1. What's on the clock face? (The child found two needles and the number 1~ 12 on the clock face. )
2. What's the difference between these two kinds of needles? What are their names?
(2) repair the clock. (Play the courseware)
Teacher: Here are four clocks made by children, which were sent to the store for sale, and the store returned them. Do you know why?
1, guide children to find the clock face error. Some numbers on the clock face are arranged counterclockwise; Some clocks have only one pointer on the dial; Some clocks have the hour hand outside and the minute hand inside; The hands of some clocks are off center.
2. Guide children to put forward suggestions to correct the above mistakes.
(3), playing clocks (courseware)
1, game: pairing.
Teacher: Show the clock face and the time card. Match the clock face and the time card. Let the children say "What is our child doing at this time" and express it with actions.
2, the game: watch the action to dial the time
Teachers do actions, children set aside time, or invite children to do actions.
Third, do it and have fun.
1, arouse children's interest in childbirth.
Teacher: Look at what material I have in my hand. (Children talk while watching)
2. Introduce the production method
Look at the picture pointer: the first group and the second group.
Teacher: Please look at the contents of each picture carefully, think about the time to do it, and then draw the time indicated by the pointer on the clock face.
Making clock faces: the third and fourth groups
Teacher: Please write the numbers on each point of the clock face first, and then put the hands and the clock face together. When the clock is finished, report the time by yourself and set the hour by yourself.
Look at the time cards. Painters: Group 5 and Group 6.
Teacher: Please choose a time card (for example, 8:00) to fill in the missing numbers on the clock face, and then draw the long hand and the short hand.
3, children's hands-on operation requires children to choose their own operating materials and make them as required.
Teachers observe children's participation in activities, so that each child can actively participate in operational activities.
Help individual children with difficulties.
4. Use some clocks to discuss with your child: Are you satisfied? Is there anything to modify? Which clock face has a problem? What's the problem?
Fourth, show children's works and comments
Let the children discuss and appreciate each other.
Summary: Today, children made their own clocks, and the design of the clocks became more and more beautiful. Clock is an indispensable thing in our daily life. It can tell us time and beautify our life. Children, study hard now and invent more and more beautiful clocks when you grow up, ok?
Activity reflection:
The scientific activity "Understanding Clocks and Watches" in the big class is an activity this semester. The purpose of this activity is to guide children to know clocks and watches, to know the names and uses of hour and minute hands, and to let children know the operating rules of hour and minute hands, and to know hours and half hours. Stimulate children's interest in observing things around them and exploring problems, experience the exploration process and develop children's exploration ability; Let children know how to cherish time and life through activities.
