A teacher is one who imparts the knowledge within, to all those who are willing to learn from. The understanding of the process of imparting the knowledge is very important before one attempts to teach. A good teacher is a person who knows the subject, the subjects (the recipients of the knowledge), teaching methodology and the objective.
Whatever the activities children do they always enjoys it. If you observe them they laugh on each and every activity they perform whether they are alone or with the parent or with other children. Really you too will enjoy their activities and will feel little relaxed forgetting if any tension mounts on your head. The children involvement in whatever they do is total from their heart not considering or thinking what other will thing about it.
