Contextualization
Roman numerals are a numerical system that originated during the time of the Roman Empire. This system is composed of seven letters from the Latin alphabet: I, V, X, L, C, D, M, which correspond respectively to the numbers 1, 5, 10, 50, 100, 500, 1000. Instead of using a positional system, like the modern decimal system, Roman numerals are written by combining letters and adding value.
Although they may seem strange or even obsolete to us today, Roman numerals played an important role in human history. They were used by the Romans for everything, from keeping financial records to denoting dates, and continue to be used in a variety of ways in contemporary society. For example, they are often seen on sundials, book chapters, the naming of queens and kings, and in sporting events such as the Olympics and the Super Bowl.
Learning about Roman numerals is more than just an interesting exercise in mathematics and history. Understanding how this numerical system worked and how it differs from our current decimal system can help develop critical and analytical thinking skills. Furthermore, understanding the origins and evolution of numerical systems can provide a broader perspective on how society and human culture have developed over time.

Practical Activity - 'Traveling Through Numbers'
Project Objective
The objective of this project is to deepen students' understanding of the Roman numerical system, its applications, and impact on society, through a fun and engaging approach.
Project Description
Groups of 3 to 5 students must create a game board that involves the conversion between Roman numerals and decimals. The game should be designed to reinforce the understanding of Roman numerals through questions and challenges.
In addition to designating a space in your home or school to play, students must create challenging question cards that test other students' understanding of the conversion between decimals and Roman numerals. It is suggested that the game also includes rules that reward group cooperation and surprise elements to make the game more exciting.
The game board, question cards, and rules should be created by the students themselves, using recyclable and easily accessible materials.
Required Materials
- Cardboard or cardstock (for the game board)
- Colored paper (for the cards)
- Colored pencils or pens (for marking the board and writing on the cards)
- Scissors
- Ruler
- Die
Activity Steps
-
Discuss and decide on the game rules: students should determine how many spaces the board will have, the rules for moving on the board, penalties and bonuses (if any), and how to win the game. Roman numerals should be incorporated into the rules.
-
Board Design: Using cardboard or cardstock, students should draw the game board. The spaces can feature numbers written in Roman numerals.
-
Card Creation: Each card should have a question about Roman numerals (for example, 'Convert the Roman number MCMXCVIII to the decimal system' or 'What is the value of the number 456 in Roman numerals?').
-
Play the Game: After preparation, students should play the game to test their rules and make any necessary adjustments.
Final Product - Report
After completing the game creation, students should write a project report. The report should be structured as follows:
-
Introduction: Should address the relevance of the topic, explain what Roman numerals are, how they are formed, and where they are used in everyday life.
-
Development: The development should cover the theory behind Roman numerals. This includes how they are formed, how they are converted to decimal numbers and vice versa. The student should detail how the game was created, the rules that were established, and how Roman numerals were incorporated into the game.
-
Conclusion: Here, students should reflect on what they have learned, how the game helped deepen their understanding of Roman numerals, the challenges encountered during the game creation, and how they were overcome.
-
Bibliography: All sources consulted during the project development should be listed.
The final result of the project (the game and the report) should be submitted within one month from the start date.
