According to the teaching philosophy and practical experience of early education, the group activity time of each small class should be determined according to the age and concentration ability of the children. Generally speaking, 12 minutes of group activities may not be enough for kindergarten children. Because children's concentration and concentration are short-lived, it takes some time to gradually expand their attention time. In preschool classrooms or kindergartens, small class group activities usually last about 20 to 30 minutes. This will allow children to participate in activities better and have enough time to absorb and learn new knowledge.

Of course, each child's attention endurance and participation may be different. Some children may need shorter group activities, while others may be able to persist in group activities for longer. Therefore, when setting the group activity time, it needs to be adjusted according to the individual differences and needs of children. At the same time, it is necessary to combine the performance and feedback of children and make flexible arrangements according to the actual situation.

Generally speaking, the group activity time of 12 minutes may be shorter, so it is suggested to extend the activity time appropriately to better meet children's learning and development needs.
