Rational numbers are an integral part of our everyday lives. From splitting a pizza into equal slices to understanding the temperature on a thermometer, rational numbers help us make sense of the world around us. One of the essential skills in working with rational numbers is ordering them, which allows us to understand how they relate to each other and make logical comparisons.
Ordering rational numbers is not just about memorizing a formula, but it's about developing a deep understanding of the number system. A rational number can be expressed as a fraction or a decimal, and the way we order them depends on the format they are presented in. In this project, we will not only explore how to order rational numbers but also understand why the order changes depending on their representation.
Ordering rational numbers is a concept that transcends the boundaries of a math classroom. It is a skill we use in our everyday lives, often without even realizing it. For example, when we compare prices in a grocery store, we are essentially ordering rational numbers. Understanding how to order rational numbers can help us make informed decisions and solve real-world problems, making it a crucial skill not only for math but for life.
In this project, you will not only learn how to order rational numbers, but you will also apply this knowledge to real-world scenarios. You will work in groups, engaging in discussions and problem-solving activities. By the end of the project, you will not only have a better understanding of ordering rational numbers but also have developed essential skills such as collaboration, communication, and critical thinking.

Activity Title: "Rational Race: An Exploration of Ordering Rational Numbers"
Objective of the Project:
The objective of this project is to develop a deep understanding of ordering rational numbers and their application in real-life situations. You will learn how to order fractions, decimals, and percentages, and understand why the order changes depending on their representation.
Detailed Description of the Project:
In this project, you will work in groups of 3 to 5 students to create a board game called "Rational Race." The game will involve ordering rational numbers in various formats: fractions, decimals, and percentages. Each group will create a set of game cards, a game board, and game rules. The game should be engaging, interactive, and educational, incorporating real-world scenarios where the ordering of rational numbers is relevant.
The game will be played in rounds, and each round will focus on ordering rational numbers in a specific format (fractions, decimals, or percentages). The goal of the game is for each player to successfully order the given rational numbers and reach the finish line first.
- Cardboard or poster board for the game board
- Markers, colored pencils, or paint for decorating the board
- Index cards or paper for creating game cards
- Ruler for measuring and dividing the board
- Dice or spinner for determining player moves
- Game pieces for each player (these can be small objects such as buttons, coins, or paper clips)
- Access to a computer and printer for creating visuals (optional)
Detailed Step-by-Step for Carrying Out the Activity:
- Form groups of 3 to 5 students. Each group should discuss and decide on a team name related to rational numbers.
- Research and brainstorm ideas for your game. Discuss how you can incorporate different real-world scenarios to practice ordering rational numbers. Each group should come up with at least five scenarios for each round (fractions, decimals, and percentages).
- Design your game board. Divide it into squares or sections, each representing a step closer to the finish line. Each square should have a scenario related to ordering rational numbers.
- Create your game cards. Each card should have a rational number or a scenario related to ordering rational numbers. Make sure to create enough cards for all players and for each round of the game.
- Decorate your game board and game cards. Use markers, colored pencils, or paint to make your game visually appealing.
- Write down the game rules. The rules should explain how to play the game, how to order the rational numbers, and how to win the game. Make sure the rules are clear and easy to understand.
- Test your game in your group. Make any necessary adjustments to the game board, game cards, or game rules based on your test run.
- Prepare your game for presentation. This includes organizing your game materials and preparing to explain your game to the class.
After you have finished creating your game, you will present it to the class. Your presentation should include an explanation of your game, the concepts you have learned, how you applied those concepts in your game, and your experiences working as a team. You will also submit a written report in the format of a project document. The document should be structured into the following sections:
- Introduction: Provide an overview of the project, its relevance, and real-world application. Also, state the objective of this project and how you plan to achieve it.
- Development: Detail the theory behind the topic of ordering rational numbers, explain the activity in detail, indicate the methodology used, and present and discuss the results obtained.
- Conclusions: Conclude the work by revisiting its main points, explicitly stating the learnings obtained, and the conclusions drawn about the project.
- Bibliography: Indicate the sources you used to work on the project such as books, web pages, videos, etc.
Remember, this project is not just about learning how to order rational numbers but also about developing essential skills such as collaboration, communication, and critical thinking. Your report should reflect these skills and your understanding of the topic.
The project is expected to take approximately five to ten hours per student to complete, and the delivery time is one week from the project's start. The written report should be submitted on the platform, and the game presentation should be done live in the classroom. Good luck and have fun!
