Teaching reflection
The creation of one situation after another captures children's interest in learning, so that children can learn to order from big to small or from small to big in their interest, and truly entertain and educate.
This course has a lot of materials for children to operate, but some children with poor ability have not finished their operations, which requires teachers to help children complete after class and let them experience the happiness of success.

(5) Summary
Teaching reflection:
Through this teaching activity, I learned that children's mathematics is very weak. In order to make them interested in math, I'm going to add more games in future math activities, so that children can have fun and learn from each other while playing. Really let children become the masters of learning and constantly improve their independent inquiry ability.
