First of all, teaching is closely linked with real life.

Cognitive standpoint is the content of the new curriculum standard, which is related to the reality of students' life. At the beginning of class, I expanded students' horizons to their familiar living space, such as sticking a pig's nose and a seat in the classroom, so that students can feel that mathematics is around, that mathematics knowledge comes from life, and that they feel the value of learning mathematics.

Second, emphasize learning mathematics in activities.

Combined with the content of teaching materials and students' life experience, open and interesting activities were carried out. Such as: delivering letters for building residents, looking for clothes, sending small animals home and so on. During the whole learning process, children feel interesting and happy.

Third, shortcomings and deficiencies.

Calm reflection after class, I still feel a little inadequate. For example, in the activity of sending small animals home, students were not instructed to look at the floor number. At the end of the class, the anti-password game was a bit confusing, because the children thought backwards and the action was still difficult.
