1. Requirements: There is only the other half of these gifts. Who can make them complete?
2. Pediatric surgery
Fourth, extension.
1. Do you know the name of this kingdom? (Kingdom of Symmetry)
2. There are many interesting symmetrical figures in the kingdom of symmetry. Let's play Symmetry Kingdom next time, shall we?
Activity reflection:
The goal of this activity has been basically completed, and the whole activity is clear and smooth, which can guide children to understand the meaning of symmetry step by step and educate them in the game. During the activity, I gave the children a space for their own exploration and practice, which reflected their position in the activity. Of course, some small details need to be improved:
1. When children operate with a pen, they should be asked to move the chair to the upper position and sit on the small chair, which is helpful for children's operation.
2. The three numbers of the first level should be marked to help children find it accurately.
3. In the process of operation, the graphics of the fifth painting are a bit complicated, which can be simplified appropriately.
Mathematics teaching plan for kindergarten large class: interesting symmetrical figure 2 activity goal;
