Golden age in children is a golden stage of development and growth that occurs in the early days of life when they are born into the world, therefore it is important for us as teachers to build the character of early childhood because they are the generation that will build this nation. The basic concept of character education in Indonesia is the education of noble values originating from religious values, Pancasila, national culture and national education goals which include aspects of moral knowing, moral feeling and moral behavior.

Students are also trained to be responsible for returning chairs neatly, being responsible for their belongings brought to the library. The teacher exercises this responsibility by reminding students at the beginning when they enter the library that they must return books to the place of return and are responsible for tidying up chairs and being responsible for their own belongings, then the teacher will remind again after the activity will end so students will remember again What should they do. This conclusion underscores how important the teacher's role is in helping children develop responsible attitudes in group play. Through a consistent and structured approach, children can understand, internalize and practice responsibility in their daily interactions.
