Elementary school children still think very self-centeredly, are rarely willing to compromise, and mix fantasy with reality. Are elementary school students too immature to empathize with others? Are they overwhelmed when they are supposed to resolve conflicts through argumentation? No, because children's everyday life is characterized by arguments, opinions, and promises. Therefore, elementary school students already possess the fundamental prerequisite: they can express their opinions! The rest is a matter of age-appropriate practice! This book shows you how to utilize the many opportunities from your teaching routine to develop and apply the argumentative potential of children in accordance with the curriculum. With a variety of methods, children prepare discussions factually, engage in dialogue with each other rather than about each other, and practice making compromises. In small, flexibly applicable units, they train to articulate their opinions clearly.
