Paying attention to the field of moral education of children in the works of Khajeh Nasir al-Din Tusi is important. The most important source which explains children's moral issues is the book of Nasiri ethics. In the second article of this book, i.e. house management and the policy of the family and children, Khajeh has discussed the education of children. He explains his educational method by considering the high and medium goals in educating the population. Explaining the virtuous approach, he states the refinement of the three faculties of lust, anger and reason as the goals of the educational mediator. The most important challenge facing this view is how to achieve these goals according to the age of the child. In the virtuous approach, the intellect achieves the intermediate goals of the moral education of children and leads them to happiness by moderating the three mentioned faculties. This article examines some of the Khajeh's strategies for operationalizing such concerns.
