1, consolidate and review to distinguish left and right with oneself as the center, learn to distinguish left and right with an object as the center, and use locative words correctly.

2. Cultivate children's sense of spatial orientation and improve the flexibility of thinking.

Activity preparation:

Paste words, small animals and ornaments.

Teaching process:

First of all, distinguish between left and right things

1, guess the import: a small tree with five branches, no leaves and no flowers. Can count, write, draw, work without talking (hands) every day.

Everyone has two hands, one is the left hand and the other is the right hand. Can you tell your left hand from your right hand? (Children's communication)

3. The teacher gives an instruction, and the child raises his hand in the corresponding position and acts according to the instruction.

Teacher: Come, come, raise your right hand.

Young children: Let's raise our right hand (to correct some inaccuracies).

Then our two hands do more things for us with their left or right hands. Please tell the children what your right hand can do. Can you perform?

The teacher stretched out his right hand and clicked on it. Q: Do you know what the teacher has? Do you know if he is my left hand or my right hand? Please raise your hand like mine.

(1) Observe and paste the label.

(2) For the wrong, the teacher and the child stand in the same direction and let the children compare, right?

Explanation: Please raise the hand holding the sticker, and emphasize again, what is our hand (right hand) holding the paper?

Thinking: Why is your right hand stuck here and my right hand stuck there?

Communication summary: the direction of standing is different. The teacher turned his back, in line with the child's direction, and then raised his right hand to let the child experience standing face to face. Because of different directions, his right hand is just the opposite of the teacher's. If the direction is the same, so is our right hand.

Second, distinguish between left and right with the object as the center.

1. Just now, we learned your right hand and left hand. The teacher tested you. Besides your left hand and right hand, what other parts of your body can be divided into left and right?

(Ears, eyes, feet, legs, shoulders, nostrils, eyebrows)

Listen to the command and do the action:

Extend your left hand and right hand; Shrug your right shoulder; Stamp your left and right feet; Touch your left and right ears; Pat your left leg and right leg. ......

Question: Is the teacher's left foot the same as yours?

Summary: mine is the opposite of yours. Your right is our left, and your left is our right.

Teacher: Several small animals saw us having such a good time and joined in the fun. Look, who's here? Q: How many small animals are there?

The teacher has prepared something here. They face you face to face. Name the objects on the left and right. Switch places.

Can we tell right from left now? (yes)

You can see the difference, but some small animals are worried. Why? This little bee is very clever. Many small animals want to make friends with it. The little bee gave them a difficult problem. If you want to make friends with me, you must answer my question. Look who's here. Bonnie brought a present. The bee asked me to test you. You stand on my left. Tutu is anxious. Which side is on your left? Please ask a child to set it up.

Here comes another small animal. Test him. Stand to the right.

Look at these little bees. They are all very good and can be my good friends.

The teacher has prepared some things here (three things, exchange places)

Tell the three children to come up and exchange places.

What's on our left? Who is sitting on our right?

Question: If we change direction, will it still be the same? (Turn in four directions, minutes or so)

Let's learn a song about right-handed people. Come along.

Come on, come on, friends, raise your right hand and swing, swing right, swing left, and follow around. Come on, friends, swing your bodies, swing left, swing right, and sit around (great)

Delineation: There is a pair (baby face) on the table to help it draw its five senses.

Listen: First draw the doll's left eye, right eye, left eyebrow, right eyebrow, left ear, right ear, nose and mouth.

Please give it to the teacher when you are finished. 1 and 2 children should be handed over to the teacher's left, and 3 and 4 children should be handed over to the teacher's right.

Summary: In this lesson, we learned to distinguish between left and right, and we also know that left and right are not fixed. If you stand in different positions, your left and right are different. If two people stand face to face, your left and right are just the opposite.

Reflections on distinguishing left and right teaching

The teaching goal of Zuoyou is to let students know their own Zuoyou, describe life in mathematical language and solve simple problems in daily life. Accurately describing the position of objects with left and right is the focus of teaching, and understanding the relativity of left and right is the difficulty of teaching. The content of this lesson is abstract, and the thinking of preschool students is based on concrete images, which is the focus of this lesson. Only by handling this contradiction well can we better implement the teaching objectives of this class and break through the teaching difficulties of this class. In order to solve this problem, I made the following attempts in teaching design. Through practice, I reflect as follows:

First of all, with the help of students' familiar left and right hands, they can identify their left and right and the position of objects.

1, which concretizes abstract knowledge, conforms to students' cognitive characteristics and is convenient for students to understand. The concept of "left and right" is very abstract. Only by building it on concrete image things can students understand and master it. But in the textbook, they have been exposed to the concept of left and right, and clearly distinguish between left and right hands. With the help of students' own right and left hands, students can know their own left and right and the position of objects, and it is easy and effective to learn.

2. With the help of their own left and right to learn new knowledge, students have a strong interest in learning. Being active is a characteristic of students. In the process of learning, students are interested in activities such as extending their left hand and right hand and stamping their left foot and right foot. Students can learn their left and right sides and the position of objects in these activities, and they can take the initiative to learn and really experience the fun of learning mathematics.

Second, with the help of activities that students are interested in, help students understand the relativity of left and right.

Understanding the left and right gender has a certain spatial concept of sexual demand, but preschool children have a weak spatial imagination. To break through this teaching difficulty, only by letting students experience the formation process of this knowledge in specific activities can students have a deeper understanding. In teaching, I organize students to shake hands face to face, stand in different positions to observe the same thing and other activities, so that students can realize that the direction is different and the left and right are different; Different observation angles, different left and right, and so on. In this way, students can not only know the knowledge of left and right relativity, but also know why, which better implements the teaching difficulties of this lesson and embodies that students are the masters of learning.

Disadvantages: Through homework feedback, I found that a few students didn't master the knowledge of going up and down the stairs to the right. Using courseware to demonstrate this knowledge seems to be abstract, which is not conducive to students' understanding. It is necessary to take students to take the stairs in person and let them experience it for themselves, so that students may master it better. In the next round of teaching, we should make up for this deficiency and constantly improve the teaching of this class.
