Once upon a time, there was a little girl named Maria. She loved playing with her toys and learning about new things. One day, she came across a book that talked about the concept of a "median." She was curious and asked her father to explain it to her.

Her father told her that the median is the midpoint of a set of numbers, just like the minute hand on a clock is the midpoint of the hour hand. Maria was fascinated and wanted to learn more.

Her father then showed her a model of a network, with nodes representing different points and a net connecting them all together. He explained that in mathematics, this is called a monoid and that it has special properties that make it useful for modeling many real-world situations.

Maria was so excited to learn about these new concepts that she spent the rest of the day playing with her toys, imagining them as nodes in a network and finding the median of their positions. She also learned about the idea of a normal distribution and how it can help us understand patterns in data.

The end.

Reflections

1. What is the median and what did Maria learn about it?
2. How did Maria's father explain the concept of a network and a monoid to her?
3. What did Maria learn about normal distribution and how did she use her imagination to understand these concepts?
