Activities to be prepared
1, courseware
On the seventh page of children's math book, each pen container has one.
Activity process
First of all, riddles are interesting
Riddle: The little tree has five branches, and it doesn't bloom without leaves. If you don't talk from morning till night, you can't write or draw without it.
Second, the difference between left and right is centered on your own body.
1, distinguish between right and left hands.
(1) Ask the children to raise the hand holding the pen, wave and communicate what they need to do with their right hand.
Please hold out your left hand and shake it.
(3) Game: Raise your hand when you hear the command.
Increase the difficulty in the game, say the opposite: I say left hand, you raise your right hand, and so on. )
2. distinguish between left and right feet.
(1) In communication, what is left and right besides left and right hands?
(Touch your ears, cover your eyes, step on your feet)
(2) Competition game: nod your head and nose.
Increase the difficulty in the game, say the opposite: I say left eye, you point right eye, and so on.
(3) Summary: Know the left and know the right, the left hand side is left and the right hand side is right.
Third, the perception of left and right.
1. What is on the left and what is on the right?
(1) Who's on your left? What's on your left in the activity room?
Who is on your right? What's on your right in the activity room?
2. Communicate in another direction. What's on the left and right?
Fourth, perceive the object-centered left and right.
1. The teacher is holding a book in his left hand. Please tell the children where the book is.
2. Discussion: The book is in the teacher's left hand. Why do many children think the book is in the teacher's right hand?
Let the children know that when facing others face to face, their left side is not the same direction as others' left side.
Ask a single child to take the book, and everyone can tell which hand he holds the book.
Five, children's operation
1. Open the children's book and tell me which hand is holding the book.
2. Circle the children with books in their left hand.

Teaching reflection
The lesson of "knowing the left and right" is one of the contents of Unit 1 of Book 2 of kindergarten teacher's class, which is taught on the basis of children's up and down, before and after learning. Using "left and right" to describe the position of objects is the focus of this lesson. Understanding the relativity of left and right is the difficulty of this lesson. In this class, I follow the cognitive rules of large class children, and use games to run through the whole teaching, so that children can build new knowledge in a relaxed and happy atmosphere.
First, when you know the "left and right", you can find the left and right games in your body from your children, so that children can participate in the learning process unconsciously, let them learn while playing, and realize their own physical mathematics. At the same time, let children talk to each other about how to determine their own left and right, so that children can get a lot of perceptual materials and get a preliminary understanding of the basic meaning of left and right. Then, from the students themselves and the children around them, let the children describe their neighbors with left and right, feel left and right, and train their language expression and reaction ability.
Second, when teaching the relativity of left and right, skillfully let the students judge whether I raise my right hand, grab the children's attention at once and arouse their thinking; Then I asked the children to raise their right hands and compete with me. I asked in time: Are you holding the wrong hand? What can we do to convince everyone? A stone stirred up a thousand waves, and the children expressed their opinions one after another, which was finally verified by my turning point conclusion. By summing up, the children understand: standing face to face, different directions, different left and right. Finally, by letting the children shake hands and take the stairs, I helped them further experience the relativity of left and right, trained their sense of left and right direction, and effectively broke through the difficulties in teaching.
Understanding the shortcomings of this lesson is children's. Language expression and listening ability need to be improved. In the class, some children are only eager to express their views, and some children find it difficult to communicate with you by hand. For children in large classes, we need to cultivate their ability in this field in the future.
Mathematics teaching plan for large class: understanding of three activity objectives;
1. Self-centered, judging left and right.
2. Train quick response ability.
Activity preparation:
PPT, music.
Activity flow:
First, the perception of left and right
1. Teacher-student interaction leads to "left and right". Children, reach out and clap together: up, down, front and back.
Second, know about.
1. Look at the picture and guess. Question: The teacher has a picture here. Can you guess whether it is left or right? Please observe and compare carefully. Hold out your hand and compare it. )
Guide children to observe the position of palm and thumb in the photo, and distinguish between left hand and right hand.
Question: What will our right hand do? Hold a pen, grasp chopsticks, bat the ball, etc. ) the other hand is ... (left hand)
Summary: It turns out that the right hand and the left hand are good friends. We must cooperate with each other in everything we do, and we must protect them.
You can tell right from left, right? Come on, have a try. Raise your right hand, raise your left hand, and remember that the hand holding chopsticks is the right hand.
Apart from hands, which parts of our body are divided into left and right sides?
1) ear. (Asking a child) Which is the right ear? (Right hand looking for right ear) Yes, right hand and right ear are on the same side. What about the left ear? (Same side as left hand)
2) Legs or feet, let's touch them together. How to find them? (left hand looking for left leg, right hand looking for right leg)
Summary: Yes, our body is divided into left and right parts.
2. The game "Finger Point".
Encourage children to listen to the password and find "left ear, right ear, left foot, right foot" and other parts by hand. A preliminary perception of the relationship between "left and right" orientation and our body.
Question: Now, the teacher tests you, I say the password, you find the corresponding part, let's try it first. Get ready … (nose nose right ear, nose nose left ear, nose nose left foot, nose nose to the right, what's the matter? Look to the left. What's there? The left hand pats the right leg and the right hand pats the left leg)
Teachers should pay attention to correcting mistakes. (Remember that the right ear is on the right hand side and the left ear is on the left hand side)
Summary: In the game, children can distinguish between "left" and "right", which is great! Yes, we just learned with the help of our bodies: the left hand side is our left, and the right hand side is our right.
Third, distinguish between right and left.
Guide children to be self-centered and distinguish between right and left.
1. Found the problem.
Question: Now I invite some children to face everyone, give it a try and see if I can find the right and left. Let the children collectively evaluate whether the direction is correct, and find that the left and right will change with the change of body direction. (Does he reach out to the right? Please try to hold out your right hand. Please put your hands in front of you and try to put your right hands in the same direction. )
Question: Why do you point in different directions when the teacher is right?
Summary: Our body directions are different, so our right side is different, because we all distinguish left from right with our own bodies as the center. So you are pointing in the right direction.
Change direction experience
Question: Let's try it together and turn around. Which one is on the left? Which one is right?
Conclusion: No matter what happens to our body direction, we always take our own body as the center to distinguish between left and right. On the left hand side ... on the right hand side ... Yes, let's try again in another direction.
Listen to the password: turn right, turn left (what's on the right and what's on the left? )
Summary: Not only can you tell right from left, but you can also listen to instructions. Turn left and right. Great!
Teacher: Now, boys please put their chairs on the left and girls put their chairs on the right, facing the teacher in a row.
Fourth, happy robots.
Test whether children can quickly distinguish between left and right with themselves as the center.
Rules of the game: We will play with robots later. Find a clearing to stand, the music starts, and all robots can walk. The music has stopped. Listen to the instruction to set the action. Try to listen to the password: raise your hand and lift your feet. (Raise your right hand, cross your right foot and look left; Raise your left hand over your left foot and your right hand over your right foot; Raise your right hand over your left foot, raise your left hand over your right foot)
The expansion of verb (verb's abbreviation) activity
In life, where do we need to distinguish between right and left? Show the pictures according to the children's answers (you should walk on the right when going up and down the stairs, and the traffic signs tell us to turn left or right ...)
Conclusion: Yes, only by distinguishing right from left can our life be more orderly and safer.
