Okay kiddo, imagine that there are different groups of people in a big room. Some people are called "politicians" because they make important decisions for our country. In Germany, there are 16 groups of politicians because there are 16 states.
Each group of politicians represents the people who live in that state and they meet in a special building called a "parliament." The parliament is kind of like a big classroom where the politicians sit at desks and talk about important things that affect everyone in the state, like how much money to spend on schools or hospitals.
The politicians in each state parliament are chosen by the people who live in that state. They have different titles like "member of parliament" or "deputy." They work together to make rules and laws for their state.
So, just like how you have a classroom with different students and a teacher, each state in Germany has a parliament with different groups of politicians and they work together to make important decisions for their state.
