# Math Modeling Real-World Topics: Voting Models

In this blog series, we're highlighting math modeling modules and articles that explore real-world issues that have broad implications.

Voting models play a crucial role in elections, and can shape the outcomes differently depending on the algorithms and criteria used. This blog post features a math modeling module that explores three main voting models so students can understand how they influence election results.

### About the Voting Models Math Modeling Module

This module is a dynamic learning tool with interactive activities designed to reinforce concepts and stimulate critical thinking. From analyzing voter preferences using preference diagrams to simulating election scenarios with different voting models, students can actively engage with the material and develop essential mathematical modeling skills.

In addition to traditional voting models, the document explores approval voting—a simple yet intriguing approach where voters can select multiple candidates they support without ranking them. Through case studies and analysis of St. Louis' first-ever approval voting election, students can weigh the pros and cons of this alternative voting model.

One of the highlights of the module is its focus on real-life election scenarios, such as Maine's 2018 U.S. House Representative election and Alaska's Senate election in 2022. By analyzing actual election data and outcomes, students can gain a deeper understanding of how voting models work in practice and their impact on democratic processes.

The document includes insights from renowned mathematicians like Kenneth Arrow, whose work on voting theory earned him a Nobel Prize in economics. By understanding Arrow's criteria for evaluating voting models and the inherent challenges in designing a perfect model, students can appreciate the complexities of decision-making in democratic systems.
