An international organization is like a play group for countries. Just like when you go to a play group, you play and interact with other kids, different countries also interact with each other in international organizations.
These organizations are made up of many countries that come together voluntarily to work towards a common goal. They usually have rules and agreements to help them achieve their goals, and they can be formed to tackle different issues such as health, peace, security, trade, and environment, among others.
Just like how friends in a play group can help each other and work together on activities, countries in an international organization can support each other and work together on important things that affect them all.
Some examples of international organizations include the United Nations (UN), the World Health Organization (WHO), and the World Trade Organization (WTO).
