The small class math activity "Little Bear Watching the Drama" began a reflection activity. On the grounds of "Children's Day is coming", I invited children to watch the scene introduction activities of the performance, and showed the tickets for the performance, so that children could observe the differences (colors and creativity) of several tickets, and then carefully explained the requirements of the game, so that children could understand that they should find seats according to the creativity on the tickets, with the red ticket sitting on the red chair and the blue ticket sitting on the blue chair. In the first game, at my prompt, the children sat down one by one, and each child found a suitable seat, and asked them to tell why they were sitting here, what color they were holding, and some ideas about tickets. In the second game, the children are fully involved. After getting the tickets, everyone looked for seats together, and the problem appeared. Some children sit in other people's seats, and some children know that others are wrong and don't correct them. They found an empty seat and sat down. Only at the prompt of the teacher and other children did I change back to my seat. Because there are many children in the class, the activities have been adjusted. Added two rows of chairs, green tickets and yellow tickets. The children in the class are asked to find seats together. After checking the tickets and finding suitable seats, they watched a VCD in front of the TV. At the end of the activity, the children performed the exercises in "Children's Picture Book" and asked the children to find out which posture the bear and his friends should take to consolidate and review what they learned today. Today's whole activity process, the atmosphere is very good, because I adopted situational teaching, the children not only learned knowledge in the process of playing games, but also fully experienced the happiness of math games.
