Social interactions include contact, communication, empathy, motivation, and adaptation. All humans are important to interact because humans are social beings.
Unfortunately children with mental retardation also experience difficulties in social life, they often withdraw from relationships or some do not understand the rules of the game that are good and right. Therefore schools are the first place they learn to interact from small groups to cross-ages. The basis of association is the presence of individual contacts, students are taught polite social procedures, believing that school and friends are a safe environment. Students are taught to foster a sense of empathy or to feel what other friends feel with real instructions that occur in school every day. Give praise, give encouragement so that all students are motivated to move and develop naturally. If all the above components are applied, students will be able to blend in and adjust to their environment.
