I know the lecture notes about big class mathematics.

Lecture Notes on "Distinguishing Left and Right" in Large Class Mathematics Teaching Plan

First of all, talk about activity teaching materials

Distinguishing between left and right is the content of spatial orientation cognition carried out by large classes this semester. The key point is to guide children to be self-centered and distinguish between left and right relationships. "Outline" said: "Kindergarten mathematics should be dominated by games, and children can get different development and improvement in games." So I designed some small games in the activity, so that children can easily master the concepts of left and right in the game. Self-centered, correctly judge the left and right, and develop children's spatial perception ability.

Second, state the goal of the activity.

The formulation of activity objectives should reflect its education, value and practicality. The activity goal is not only the starting point and destination of the whole educational activity, but also plays a guiding role in the activity. Therefore, in order to meet the development needs of children's cognition, emotion and ability, I have set the following goals:

1, perceive the spatial orientation of "left" and "right", and develop the perception and judgment of spatial orientation;

2. Stimulate children's interest in communicating with peers, and accurately tell the "left" and "right" directions of objects;

Third, talk about the difficulties of the activity: developing children's perception and judgment of spatial orientation;

Fourth, talk about activity preparation: 1, venue layout: hang something on the left and right of the activity room;

2, 40 blue and green belts, tied to the children's hands before class;

3, children's book "Mathematics" page 12, scissors, glue;

Five, said the activity process:

Link 1: Distinguish between right and left hands

I started guessing riddles. Today, the teacher brought a riddle to everyone, and wanted to test everyone: "A small tree has five branches, the leaves don't grow, they don't bloom, they can count, they can write and draw, they work every day, and they can't talk." The child answers and leads to the answer: hand. Teacher: Everyone has two hands, one is the left hand and the other is the right hand, so can you tell your left hand from your right hand? Children can communicate.

Do you know which left hand is which right hand? Let me test you and see if you can do as I say.

1, the teacher gives an instruction, and the child raises his hand and makes an action at the corresponding position according to the instruction.

For example, please raise your right hand and wave it, give a thumbs-up and make scissors; Please raise your left hand, clench your fist and blink; (The teacher sees if the child is right and corrects individual mistakes.)

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 tell us how to do it?

3. Game: I'll do it if you say so.

Please tie a blue and green belt on your hand before the game.

-When the teacher gives instructions, children will raise their left hand or right hand (for example, ask children with blue ribbon in their right hand to raise their hands, and children with green ribbon in their left hand to raise their hands)

The design intention of the first link: the children in the big class have a certain understanding of the left and right, but they really don't know much about it, so I start with the left and right hands in the first link, because the children know that the right hand will help us do many things, such as writing, drawing, holding chopsticks, lifting things and so on. And they will have a better grasp of the concept of left and right hands, paving the way for the next link to understand the left and right parts of the body.

Link 2: Distinguish between left and right feet

1, just now we know the left hand and the right hand, so the teacher wants to test 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,)

2. The teacher gives instructions, and the child listens to the instructions to complete the corresponding actions.

Please lift your left foot, please lift your right foot; (The teacher looks at whether the child is raising a team and corrects individual mistakes.) After several times, the difficulty can be improved and the child is required to do the opposite of the instruction; (I said left foot, you lift your right foot)

Design intention: stimulate children's interest in learning through the game and perceive the left and right spatial orientation in the game;

Link 3 Left and Right Perception

1. Children communicate what is on their left and right.

2. What will the child say about his profile after changing his orientation?

3. Game: Little Bear moves: Complete the children's book 12 pages, and let the children help Little Bear stick some furniture in the corresponding position!

Design intention: to stimulate children's interest in communicating with their peers, and accurately tell the "left and right" orientation of objects, so as to better master the knowledge they have learned.
