Comparing how much is the beginning of children's cognition, which is very suitable for the age characteristics of preschool children. However, simple learning "how much is equal to how much" is more abstract and boring than younger children. Children in preschool classes are young, playful and have short attention time. If it is accompanied by game activities, let them learn while playing. It can not only meet the needs of children's play and activities, but also achieve the purpose of activities well. According to the goal of this idea, when I design this activity, I design activities close to children's lives from the interests of children. Through activities, children are initially guided to perceive and understand "how much" and "as much", which can be expressed in simple language, thus initially cultivating children's observation ability.

At the beginning of the activity, I used the game of finding bottle caps to lead in. Ask the children to help three bottles of different colors find the caps of the corresponding colors. Let the children discover the relationship between the bottle and the lid while operating. Children will say "there are more bottles than lids", and so on. In this activity, I didn't tell my child to use the "one-to-one correspondence" method, but let him cover the bottle cap, initially perceive and understand "how much" and "as much" and express it in simple language. During the whole activity, children can basically actively participate in happy game activities and enter scenes and roles.

This class has some shortcomings:

1, the classroom discipline is not very good. Preschool children are active and love to play. When they hear that they are playing games, they are all excited. The classroom is a mess. Classroom cultivation education needs to be strengthened.

2. Children's language expression ability needs to be strengthened.
