Activity purpose:
1, can think positively and make judgments in time.
2. Learn how to compare the thickness of objects.
3. Be able to correctly use "coarse" and "fine" to describe the differences of objects, and know that the comparison of thickness is relative.
4. Cultivate children's brave and lively character.
Focus of activities:
Learn how to compare the thickness of objects.
Activity difficulty:
To know that the comparison of thickness is relative, we can use thickness to describe an object.
Activity preparation:
Prepare pens, bottles and books of different thicknesses for children.
Activity flow:
First of all, the beginning: introduce the conversation.
The Monkey King will change. What is a powerful weapon in the Monkey King? (Golden hoop) Golden hoop can be thickened or thinned.
Second, the basic part
1, the teacher shows a thick object and a thin object, please tell the children.
(1) Which is thicker?
(2) Which is finer?
(3) How do you know whether it is thick or thin? Inspire children to know that they know it through comparison.
2. The teacher shows different thick and thin objects by changing games, and knows that the thickness is relative.
3, the game changes, the teacher said that when the child is thick, the child's hands make a thick appearance, the teacher said that when the child is thin, the child's hands make a thin appearance, and deepen the understanding of thick and thin through the game.
Third, the end of the activity:
The teacher asked the children to finish the books for them by playing courseware.
Activity expansion:
Compare the thickness of various objects in the surrounding environment, and compare the thickness of various things at home after returning home and make records.
Activity reflection:
The disadvantage of this activity is that it was not arranged during the introduction. I mentioned that I chose the Monkey King's golden hoop to attract children's interest, but it was a little too close to my goal of being crude and refined. The children basically talked happily around the topic of the Monkey King's golden hoop. When I got to the topic of coarse and fine, the children were talking about the Monkey King's golden hoop in high spirits, which made me a little anxious. I think at the beginning of this introduction, I should choose a simple and straightforward introduction. (1) I can use small animals to live in my new home. The big one can live in a big room, and the small one can live in a small room, because the big room is thick and the small room is thin. (2) I can directly take out two objects with different thicknesses for children to observe, so that children can understand the difference of thickness through intuitive visual inspection. (3) I can also overlap several paper barrels.
I feel that I haven't done enough in the change of activities. I can accept change, whether it is thick or thin. I used to go bold and thin, which seemed a little too simple and not interesting enough.
There are not enough teaching AIDS in the activity. I want to make a set of thick and thin paper buckets for children to observe and explore for themselves.
This activity gave me a warning. In future activities, I will think deeply, think deeply, and constantly reflect on the mistakes in the activities to avoid making mistakes again.
