Project: Percentages and Entrepreneurship: The Art of Doing Business with Numbers

Introduction

The concept of percentage is one of the fundamental pillars of mathematics and finds widespread use in various other disciplines as well as in countless practical scenarios in daily life. Percentages enable us to compare quantities in a relative manner, making them a powerful and versatile tool for analysis, evaluation, and decision-making.

Percentages provide a way to express a fraction of 100 as a ratio or proportion between two numbers. This is especially useful for comparing values of different sizes. For example, if you received a 5% raise on a salary of $1000, it would result in a $50 raise. If the same 5% raise were applied to a salary of $2000, it would result in a $100 raise. Thus, percentages can be used to express changes over time, increases or decreases, and discounts or rates.

Percentages are also essential in financial literacy, enabling individuals to comprehend how interest, discounts, and taxes work, among other things. For example, if you want to buy a product that offers a 20% discount or determine how much interest you will pay if you delay paying a bill, percentages come into play. Understanding how percentages work is necessary to make sound financial decisions.

Mathematics, particularly percentages, finds application in numerous everyday situations in diverse domains such as cooking, meteorology, economics, and science. A solid understanding of this concept can thus aid not only in solving classroom problems but also in making everyday decisions and comprehending the world around us.

To enhance your foundational understanding and delve deeper into this topic, I suggest consulting the following resources:

• Khan Academy: Percentages
• Só Matemática: Percentagem
• YouTube Channel Matemática Rio: Percentagem
• Book: "Matemática e suas Tecnologias". Authors: Luiz Roberto Dante. Edition: 1st Edition. Publisher: Ática, 2005.

Through this project, we aim to demonstrate that mathematics is not merely a collection of formulas and equations but a tool that empowers us to better understand and interact with the world around us.

Hands-on Activity

Activity Title:

"Fostering Entrepreneurship: A Percentage-Driven Simulation"

Project Aim:

To grasp the critical role of percentages in various business and financial scenarios, developing proficiency in calculation, understanding economic variables, and decision-making.

Project Description:

Students will be divided into groups of three to five. Each group will be responsible for creating and managing a fictitious "business". They will determine the nature of their business, create a basic business plan, establish prices for their products or services, and calculate operational costs. The groups will utilize percentages to calculate profit, interest, discounts, taxes, and other economic variables.

These fictitious businesses will operate in a simulated market environment, with other groups acting as their competition. Groups will need to adjust their business operations based on hypothetical market events introduced by the teacher (e.g., a surge in inflation, a decline in sales due to a simulated pandemic, etc.).

The project will be integrated with history lessons, where students will learn about the evolution of trade and economic practices, providing them with a broader context to understand the significance of percentages in business.

Required Materials:

• Calculator
• Paper and pencils
• Computer with internet access for research

Step-by-Step Activity Instructions:

1. Form groups and choose the type of business.
2. Create a basic business plan using online resources and textbooks.
3. Set prices for products or services and calculate operational costs.
4. Calculate profit, discounts, interest, and taxes using percentages.
5. Adapt business operations to hypothetical market events, recalculating variables as needed.
6. Prepare a final report documenting the entire process, uses of percentages in different contexts, and decisions made.

Project Deliverables:

Each group is required to submit:

1. The business plan.

2. Percentage calculations related to their business (profit, discounts, interest, and taxes).

3. A final report, which includes:

   • Introduction: Background on the type of business chosen, applications of percentages in that business sector, and project objectives.

   • Development: Detailed discussion of the process of creating and managing the business, strategies employed, justification for decisions made, in-depth explanation of how percentages were utilized in each business context. Presentation and analysis of results obtained.

   • Conclusion: Reflection on key takeaways, discussion of skills developed, assessment of the business's performance and decisions made, and final thoughts on the importance of percentages in business.

   • Bibliography: All sources consulted during the project, such as books, web pages, videos, etc.

4. A class presentation on their business, explaining its operations and how percentages were applied.

Students will work collaboratively to create and run their business and to write and present their report. This will enhance their teamwork, communication, and time management skills, in addition to their mathematical abilities.
