Mathematics is an abstract and thinking subject. Guide children's superficial basic knowledge of mathematics, cultivate children's initial logical thinking ability, create spirit and various abilities, and promote children's intellectual development. Develop children's "sense of time" by guiding them to initially perceive the concept of time. Establishing children's concept of time is gradually formed on the basis of rich perceptual experience.

According to the actual situation of children in the first class, children are more literate, know the time concepts of yesterday, today and tomorrow, and know the formation of a week. Therefore, in the activity design, I integrate "year, month and day" into the story, so that the characters and stories are skillfully combined, and the original abstract and complex concepts become concrete, concise and easy to understand, leaving room for children to actively explore and learn.
