Teaching process (this article comes from Feifei. Lesson. One piece Garden, excellent educational resource network);

First, pre-school preparation

1, investigation

(1) Question: What kind of calendar have you seen?

(2) Common display calendars in life: whole book, loose leaf, desk calendar and book calendar.

(3) Thinking: How are these calendars made?

(4) Question: Do you want to make your own almanac?

Fourth, use

Think about what else you can do with your calendar.

Reflection after class:

1, guide students to work together and learn to communicate.

In practice, students should not only learn how to solve problems, but also learn to cooperate and communicate. In the activities of making calendars in groups, teachers should pay attention to guiding each group and guide them to cooperate according to their own specialties, such as "Who designs lace", "Who writes the date of each month" and "Who marks important festivals" shown in the teaching materials. In addition, after the production activities, the production results were also displayed and exchanged. In the exhibition, students not only experienced the joy of success, but also appreciated and learned the advantages of others, and cultivated the consciousness of recognizing and learning from others.

2. Pay attention to let students realize the close connection between mathematics knowledge and real life.

In teaching, teachers guide students to experience the role of calendars in real life. Ask the teacher's question "What else can you do with your calendar" to arouse the students' discussion.
