Contextualization

Theoretical Introduction

Polynomials are mathematical expressions widely used in different areas of mathematics and sciences. They are represented by a sum of products of a variable (usually x) by a constant, with the variable raised to an integer exponent.

Factoring is a process that aims to transform a polynomial into a product of simpler factors, facilitating some calculations. It can be understood as the inverse operation of multiplication. For example, the polynomial 2x² + 3x - 2 can be factored into (2x - 1)(x + 2), transforming a complex expression into two simpler ones.

The factoring process is a fundamental skill that every math student should master. Knowing how to factor polynomials will help you solve higher-degree equations, simplify algebraic expressions, find the roots of polynomials, among other applications.

Contextualization

Factoring is an important concept not only in mathematics itself, but also in various practical applications. In physics, for example, polynomials and their factoring are used to describe and solve problems related to the motion of particles and larger objects. In engineering, they are used to model and predict the behavior of complex systems.

Furthermore, factoring polynomials is an essential tool for computer programming and algorithms. It is used, for example, in computer-aided design (CAD) software and artificial intelligence algorithms.

The ability to factor polynomials is, therefore, a valuable tool that will enrich your mathematical repertoire and expand your professional possibilities.

Practical Activity - "Polynomials in Action: Factoring Game"

Project Objective

The objective of this project is to facilitate the understanding of polynomial factoring through a playful group game.

Detailed Project Description

Each group of students (3 to 5 students per group) will have the task of creating a board game related to the theme of polynomial factoring. The students will have one week to complete this task, and it is expected that each student will invest between two to four hours of work in the project.

Required Materials

1. Cardboard or cardboard for the base of the board.
2. Pencils, pens of various colors, and a ruler.
3. Creativity to invent fun and educational rules for the game.
4. Polynomials to be factored. These polynomials can be found in math books or websites, or the students can create them themselves.

Detailed Step-by-Step for Carrying Out the Activity

1. Hold a virtual or in-person meeting with your group and decide on the game rules, the layout of the board, and the polynomials to be used.
2. Sketch the game layout on the cardboard or cardboard. Be sure to include a path to be followed by the players, spaces for questions/answers, and any obstacles or rewards.
3. Write the game rules. The rules should be clear, fair, and have an educational component. For example, a rule may be that, to advance on the board, the player must correctly factor a polynomial.
4. Create cards or tokens with the polynomials to be factored. Be sure to include the answer on the back.
5. Do a final check to ensure that everything is correct and ready to be played!
6. Play the game with your group to see if it works and if it is fun and educational.
7. Prepare a presentation about the game for the class, including the rules, the board design, and the obstacles/rewards. Share what you learned from the process.

Project Deliverables

The deliverables of this project consist of:

1. The physical board game.
2. A presentation about the game for the class.
3. A written report presenting the project. This report should include:
   • Introduction: Containing the theme, its relevance and real-world application, and the project's objective.
   • Development: Explaining the theory of polynomials and factoring and detailing the process of creating the game. Here, students should describe step by step how the game was created from the initial idea to the final execution. All materials used, the established rules, and the board layout should be detailed in this section. Additionally, they should present and discuss the results obtained, that is, the feedback the game received during test plays.
   • Conclusion: Summarizing the main points, explaining what was learned during the project, both in the technical aspect (polynomial factoring) and in the development of socio-emotional skills (time management, teamwork, problem-solving, etc.).
   • Bibliography: Listing all sources used for creating the game and for preparing the report.

It is expected that this project will encourage collaboration, creativity, and the direct application of mathematical concepts in a fun and engaging format.
