From an early age, children begin to ask questions of their surroundings - parents, families, teachers. The answers to these questions are very important because they can lead to the development of prejudices, stereotypes and discrimination among children. The view of the world created by people is conditioned by several factors, the most prominent of which are life experience and upbringing, a person's personality and the environment in which he creates attitudes. From the above it can be concluded that each individual has their own way of experiencing the environment and the world and it is important to explore and understand different perceptions of the same. A stereotype can be considered a generalization and a simplified understanding of some groups of people and does not take into account possible differences between individuals in the group. The impact of stereotypes is manifested in the fact that the traits we attribute to groups of people become the basis for discrimination and prejudice. Prejudice is the creation of an opinion/decision about an individual or a group of them without facts and real knowledge about them. Discrimination means separating, distinguishing on various characteristics such as social, educational, racial, religious and others. In the fight against discrimination, the most important thing is to work on preventing its occurrence. Children are not born with negative attitudes towards different groups of people, but they are a reflection of the environment in which they live and the attitudes of teachers and parents.
