# Dash & Dot: Dash & Dot Are So Random (Gr. 4-6)

**Description**

So much around us happens randomly. How can Dash and Dot simulate random events when they have to follow a strict algorithm? In this lesson, students will learn how random variables can be utilized in computer programs.

**Objectives**

- Understand what random variables are and when to use them
- Write a program that uses a random variable
- Find measures of center for a set of data and use them to describe the data
