Exponential Dice

#### Activity Overview

This lesson involves using a simulation to generate data that can be modeled by exponential growth and decay functions.

#### Objectives

• Students will analyze data determined by a simulation involving tossing dice.
• Students will find and analyze exponential growth and decay functions.

#### Vocabulary

• exponential decay function
• exponential growth function
• half-life
• doubling time
• simulation

#### About the Lesson

This lesson involves using a simulation to generate data that can be modeled by exponential growth and decay functions.

As a result, students will:

• Determine an exponential function fitting a data set using simulation, exponential regression, and theoretical analysis.
• Analyze properties of exponential growth and decay functions such as doubling-time and half-life.
