Mathematics teaching plan for kindergarten middle class: big bear's storage room
Design intent
On the basis of perceptual experience, the children in the middle class began to generalize and classify specific things, but the level of generalization and classification was still very low. Therefore, the goal setting and link design of this activity are mainly based on the plot of the picture book, through the combination of perception and operation experience, and strive to enable children to summarize the external characteristics of food through activities, classify according to the two characteristics of objects, feel the importance of classification, and thus develop mathematical thinking ability.
Teaching objectives
1. Look, talk and do, and feel the importance of classification in life.
2. Try to summarize the external characteristics of food and learn to classify objects according to their two characteristics.
Teaching preparation
Teaching AIDS: PPT for picture books, PPT for classification of daily items, color labeling and size labeling.
Learning tools: all kinds of food pictures, each person operates paper.
Teaching link
First, dialogue import
1. Teacher: It's getting cold. Do you know what season it is? Autumn is the harvest season, and Kenny Bear has prepared a lot of food and put it in the storage room for the winter.
Let the children guess what food the bear will put in the storeroom.
2. Play the picture 1 to 4: Perceive the external characteristics of food.
1. Teacher's question: What food did the bear prepare? Guide the child to tell what it looks like and what color it is. How much food the bear has prepared! So he plans to put all the food in the storage room, but the storage room can't pile things up. Bear decided to tidy up.
2. Teacher's question: How to organize! Who will help bear advise? The way children think is really good,
Let's see how bears do it. The bear said, let me tidy up!
Third, play the story pictures five or six, summarize the color characteristics and know the color code.
1. Teacher's question: How are the big bears divided? What is the classification? (Color) How many kinds of food does the bear divide by color? (yellow, red and green)
2. Know the color code: Big bears are divided according to the color of food, which can be expressed by color code. For example, bananas, pears and dried fish are all yellow, which are indicated by yellow marks.
3. The game "Wrong Search": The big bears are divided by color. There seems to be a mistake. Who will find this mistake? Bears are classified by color, but this method seems inappropriate and can't be put in the storage room.
Fourth, play the story screen seven or eight: summarize the size characteristics and identify the size marks.
1. Teacher asks: What is the classification of the big bear this time? (size)
2. Know the size mark: Big bears are divided according to the size of food and can be represented by size marks.
3. The game "Wrong": Did the bear score correctly this time? Please find the wrong one! Bears are classified according to their size. But there seems to be not enough space in the storage room!
5. Operation activities: Help the big bear to classify food according to its color and size characteristics.
Teacher: Big bears are divided by color, and they are all in trouble. Let's help the bears!
1. Requirements: There is a lot of food brought by the bear on the table. Please divide Bear's food by color and size.
3. Demonstration homework (collective and individual) is classified according to the scores on the homework paper.
4. Children's operation and teacher's guidance. Remind children to read the marks clearly and classify them.
5. Comments: Show the results of children's operations.
Sixth, continue to read the story and understand the method of secondary classification.
Teacher: children do have the ability to help bears classify food according to its color and size, but the little monkey in the story has another way to help bears divide food. Do you want to know?
1. After reading the story, ask: What method did the little monkey use? What was the score for the first time? What about the second time?
2. Summary: The little monkey divided the food type for the first time and the food size for the second time. This is a secondary classification, which we will learn later.
Seven, watch the PPT classification of daily items to understand the application of classification in life.
1. Look at PPT, Teacher: Use the classification method to make the storage room of Bear look neat. There are also many places where classification is used in our life. Let's have a look!
2. Teacher's summary: Classification is very useful. Let's go back to the classroom and tidy up books, toys and other items to make the class look cleaner.
