How To Guard An Art Gallery: A Simple Mathematical Problem, Natalie Petruzelli

The Review: A Journal of Undergraduate Student Research

The art gallery problem is a geometry question that seeks to find the minimum number of guards necessary to guard an art gallery based on the qualities of the museum’s shape, specifically the number of walls. Solved by Václav Chvátal in 1975, the resulting Art Gallery Theorem dictates that ⌊n/3⌋ guards are always sufficient and sometimes necessary to guard an art gallery with n walls. This theorem, along with the argument that proves it, are accessible and interesting results even to one with little to no mathematical knowledge, introducing readers to common concepts in both geometry and graph …

Have you ever wondered exactly how much land and space are included in a national park? In this paper, we will explore the vastness of a fictitious Park and calculate its total area.

We will:

1. Create a fictitious Park, determine a scale that can be used to perform

calculations using a practical unit of measurement.

2. Develop a strategy that students can use to find the area of the Park.

3. Demonstrate the use of the strategy by solving for the area of the fictitious park.

Solving Logic Problems With A Twist, Angie Su, Bhagi Phuel, Chloe Johnson, Dylan Mandolini, Shawlyn Fleming

Transformations

The crossroads of logic and mathematics breeds critically thinking students that have the confidence and independent working skills to tackle any problem they come across. In this artifact, several applications of logic to common problems have been applied in a way that would allow teachers to use the examples in their classrooms in a wide range of grade levels. More specifically Boolean Algebra and Truth Tables have been making their way into middle and high school mathematics classrooms with the nation's shift from just being able to compute to an understanding on a cognitive level why you solved the problem …
