Contextualization
Introduction
Fractions are numbers that represent parts of a whole or a group. They consist of two numbers separated by a line, with the number on top called the numerator and the number on the bottom called the denominator. The denominator indicates how many equal parts the whole is divided into, while the numerator represents how many parts we are considering.
Adding and subtracting fractions can be challenging for many students. However, by understanding the concept of fractions and visualizing them, we can simplify these operations and make them more manageable. The key to mastering these operations is to ensure that the fractions have a common denominator.
In this project, we will delve into the world of fractions, understanding their structure, and exploring the rules for adding and subtracting them. We will then apply these concepts to solve realworld problems, demonstrating the practicality and importance of these operations.
RealWorld Relevance
Fractions are not just mathematical concepts; they are all around us in our daily lives. From dividing a pizza into slices to sharing a cake with friends, we are constantly dealing with fractions without even realizing it.
Moreover, fractions are extensively used in cooking and baking. Recipes often require us to add or subtract fractions. For instance, if a recipe asks for 1/2 cup of flour and we want to make a double batch, we need to add 1/2 and 1/2, resulting in 1 cup of flour.
Furthermore, fractions are essential in many professions, such as carpentry, engineering, and architecture, where measurements often involve fractions. Understanding how to add and subtract fractions accurately is critical to ensuring the precision and integrity of structures.

Practical Activity
Activity Title: "Fraction Feast: A Delicious Journey into Adding and Subtracting Fractions"
Objective of the Project
The main objective of this project is to entrench the understanding of adding and subtracting fractions. Students will work together to create a recipe book that incorporates these operations. The book should contain detailed recipes that involve adding and subtracting fractions, along with clear stepbystep explanations of how these operations are applied in each recipe.
Detailed Description of the Project
Students will form groups of 35. Each group will be tasked with creating a unique recipe book containing at least five recipes. These recipes must involve adding and subtracting fractions in their measurements. For example, a recipe may require adding 1/4 cup of sugar and 1/3 cup of flour.
The groups should not only provide the correct measurements for each ingredient but also explain the process of adding or subtracting the fractions. This could be done through diagrams, stepbystep explanations, or even short videos demonstrating the process.
The final recipe book should be neatly organized and visually appealing. It should provide clear examples of adding and subtracting fractions in realworld contexts, making the concept accessible and engaging.
Necessary Materials
 Recipe book or notebook for each group
 Writing materials (pens, pencils, erasers)
 Rulers or measuring tapes for creating diagrams
 Ingredients and kitchen utensils for recipe testing (optional)
Detailed StepbyStep for Carrying Out the Activity

Form Groups and Assign Roles  Form groups of 35 students. Each member of the group should be assigned a specific role, such as recipe developer, mathematician (in charge of the calculations), writer, and visual designer.

Brainstorm Recipe Ideas  As a group, brainstorm ideas for your recipes. Ensure that each recipe involves adding and subtracting fractions in the measurements. For instance, a recipe may require adding 1/2 cup of sugar and 1/4 cup of butter.

Develop Recipes and Perform Calculations  Once you have decided on your recipes, develop detailed stepbystep instructions for each one. Make sure to include the correct measurements for each ingredient, demonstrating the process of adding and subtracting fractions. Perform the necessary calculations to determine the measurements.

Create Visuals  Create visuals to aid in understanding the process of adding and subtracting fractions. These could be diagrams showing the division of a whole, or pictures demonstrating the recipe steps.

Assemble the Recipe Book  Neatly organize your recipes and visuals in your recipe book. Make it visually appealing and easy to understand.

Review and Edit  Review your recipe book as a group, making sure all the explanations are clear and the calculations are correct. Make any necessary edits or revisions.

Submit the Project  Submit your final recipe book to your teacher.
Project Deliverables
The final deliverable for this project is the recipe book. This book should contain at least five recipes, each involving adding and subtracting fractions. The book should have clear, detailed explanations of how these operations are applied in each recipe, along with visuals that aid in understanding the process.
Project Report
In addition to the recipe book, each group must submit a written report that documents their work. The report should include the following:

Introduction  Contextualize the project, explaining the concept of fractions, why they are important, and how they are used in realworld situations.

Development  Detail the recipes you chose and why you chose them. Explain the process of adding and subtracting fractions in each recipe, providing the necessary calculations and stepbystep explanations. Discuss the visuals you created and how they help in understanding the concept.

Conclusions  Reflect on what you have learned about adding and subtracting fractions through this project. Discuss any challenges you faced and how you overcame them.

Bibliography  List all the resources you used to work on the project, including websites, books, and videos.
The written report should be approximately 5001000 words long and must be submitted along with the recipe book. This report, along with the recipe book, will be used to evaluate your understanding of adding and subtracting fractions, your ability to work in a team, and your creativity in presenting the information.
