Reflection after class:

In order to better carry out the research on the subject, we posted comic books of folk stories drawn by teachers on the corridors and stairs to deepen children's understanding of folk stories. "The Elephant in Cao Chong" is an intellectual story, and there are many puzzles when designing it, because the problem is difficult to extract, and how to express the method of elephant weighing in a language that children can understand. But when I was in class, the children already knew the story. When a question was thrown down, the children answered immediately, so there was no chance to guess. The whole class is very short, so I only use videos. It is best to use PPT when you understand the story in sections, and use video when you fully appreciate it at last. Although the classroom effect is not as good as expected, it is also a new attempt for myself, and I have gained valuable experience in material selection-design-trial teaching.

Please read the text gently and emotionally, first mark how many natural paragraphs there are in the text, and then think about what happened in the text while reading. (The teacher shows the fifth slide to guide the students to learn)

(1) After reading it, the students all know one thing about this text: this text mainly tells the story that Cao Chong wanted to be an elephant when he was a child. The teacher asked to see the story behind the fifth slide. )

F. The teacher (the teacher shows the slide 10 for guidance) guides the students to look at the pictures and talk, and inspires the students to think: the elephant is tall and big, with a body like a wall, legs like four pillars, ears like, nose like and tail like.

3. Teacher's Quotations: Listen to the teacher read the third paragraph, and think while listening: What methods do officials have to weigh elephants? (The teacher shows the slide 1 1 for guidance) Learn the third paragraph to understand the representation of officials:

(1) Practice reading in groups of four students, and then switch roles. (The teacher shows the second half of the slide of 1 1 to guide the students to read the sentences. ) Cao Cao asked, "Who can weigh this elephant?" Some said, "You have to build a large scale and cut down a big tree to make a scale." Some people say, "Large scale is not enough. Who has the strength to lift such a big scale? " Others said, "One way is to kill the elephant, cut it into pieces and weigh it." Cao Cao shook his head.

(2) Thinking and discussion: What methods have the authorities proposed? Are their methods good? Why?

official

Make a big scale and weigh the elephant (teacher shows 12 slides to guide)

Slaughter an elephant and call it an elephant (teacher shows 13 slide to guide)

Cao Cao is not satisfied (the teacher shows 14 slides to guide)

4. Teacher's Quotation: What should Cao Cao do if he is not satisfied with the way officials call elephants? Let's learn the fourth natural paragraph together, and experience the originality of Cao Chong's image representation method: (Teacher shows 15 slide to guide the group to learn cooperatively): A, the students in the group tell each other how Cao Chong is regarded as an image? Draw it with a horizontal line. B. Discuss with each other: How many grades does Cao Chong call elephants? What can you say?

(1) Free reading requires familiarity: Cao Chong, son of Cao Cao, is only 7 years old. He stood up and said, "I have an idea. First, drive the elephant to a big ship and see how much the hull has sunk. Just draw a line beside the boat along the water. Then the elephant was driven ashore, and the stone was loaded on the boat until the boat sank to the place where the line was drawn. Then, weigh the stones on the boat. How heavy the stone is, you will know how heavy the elephant is. " (Teacher's presentation 16 slide to guide group cooperative learning)

(2) (The teacher shows the slide 17- 19 to guide the group to study cooperatively) Show the sentences on the slide according to the words, such as "first".

(3) The experimental demonstration named students to the podium, saying that while demonstrating Cao Chong's image method through props experiments, the teacher reminded the whole class to observe carefully. (The teacher shows the 20th slide to guide the students to talk about the steps of Cao Chong's image. )

(4) (Teacher shows slide 2 1) Guide students to compare and say which of the three methods is better. Three methods:

A, build a big scale, cut a big tree to make a scale.

B, kill the elephant, cut it into pieces and weigh it.

C. Drive the elephant to the boat and weigh it with the boat.

D. Thinking and discussion: Is Cao Chong's method of weighing image good? Why?

(Through discussion, students know that the ship is used instead of the scale, which solves the problem of lifting; Replacing elephants with stones solves the problem that elephants can't be cut and weighed, thus realizing that Cao Chong is smart, good at observing things and likes thinking. )

5. (The teacher shows the 22nd slide) Inspire the students to tell other better ways to weigh the image: Cao Chong is only 7 years old, so smart, and you are about his age. In today's technological progress, do you have any other better ways to weigh the image? Talk to each other at the same table to see who has the simplest method and the least harm to elephants!

The teacher inspired the students to say that there are other better ways to weigh the image and make the students' thinking more innovative in today's technological progress. )

Cao Chong said the third way is good: Cao Chong is smart, good at observing things and loves to use his head.

Cao Chong Elephant Kindergarten Teaching Plan Chapter III

Teaching material analysis:

"Xiangxiang" is a folk historical story. By introducing the concrete methods and steps of Cao Chong's elephant-weighing, and comparing with the methods of senior officials, the activity showed Cao Chong's qualities of being fond of brains, observant and full of associations. The story is vivid and fascinating, and the language is easy to understand, so that children can understand the story soon. This story is mainly to let children know that ancient people are good at using their brains and how to weigh elephants, and at the same time, to cultivate children's good qualities of using their brains and being diligent in observation through stories. To solve this problem, it must be based on children's understanding of the conservation principle of quantity, so that children can know that we can replace quantity through the conservation principle of quantity. This story is too abstract and relatively difficult for large class children, so I divide the story into two classes. The first lesson is mainly to let children know the principle of conservation of quantity. In the second class, on the basis of children's initial understanding of the conservation principle of quantity, let children retell stories with expressions and vividly, and improve their oral expression ability.

Let's talk about the first class first. The first lesson is mainly to let children know the quantity. Substitution of quantity in conservation principle. So I think the focus and difficulty of this activity is to let children know how Cao Chong is known. In order to solve this problem, we have set the following goals:

1, a good understanding of Cao Chong's image in the story, a preliminary understanding of the conservation principle of quantity.

2. Cultivate children's good qualities of using their brains and being diligent in observation.

Link analysis:

1, dialogue import.

Let the children talk about their life experiences. If you want to know the weight of something, what will you do? This link can not only lead to the story of the next link, but also pave the way for solving difficulties.

2. Enjoy the story completely.

This link is mainly to let children have a general understanding of the story. At the same time, I know that it was so difficult for ancient people to weigh an elephant, so how did they weigh it? Is this method ok? Why not? Let children compare the methods of senior officials and Cao Chong, which can develop their comparative thinking.

3. Appreciate this passage by Cao Chong, and focus on understanding the replacement principle of Cao Chong's dosage.

This link is to break through the difficulties. Children's thinking is more intuitive and vivid. It is difficult for children to really understand the story, let alone the abstract conservation principle. Courseware is more intuitive, so that children can know the steps of Cao Chong's image. After enjoying the courseware, the child knows the steps of the image, but is replacement equally important? It is still hazy, so we need to demonstrate the operation by experiments to verify this principle. Let children further understand the principle of conservation. In fact, this link is also the link to implement these two goals.

4. Enjoy the story completely again.

Appreciate the story on the basis of children's initial understanding of Cao Chong's iconography, so as to truly understand the story.

5, combined with the actual situation, divergent thinking of children.

Inspire children to combine their own life experiences and think from the two aspects of the situation at that time and modern society. Encourage children to take the initiative to participate, boldly imagine, encourage innovative thinking and cultivate innovative spirit; At the same time, let children know more about Cao Chong's wisdom, and stimulate children's good habit of using their brains actively.
