Contextualization
The rectangle is a polygon with four sides, a geometric shape that has four right angles (90 degrees). Its uniqueness lies in the fact that, regardless of the size of the sides, the angles will always be right angles. This makes the rectangle a fundamental figure in Euclidean, flat geometry.
In this journey into the world of the rectangle, we will come into contact with subjects such as the Pythagorean Theorem, which is essential for understanding the behavior of rectangular figures. In addition, we will discuss the properties of angles and symmetries in the rectangle, and how we can use them to obtain relevant information about the object under study.
Furthermore, we will discuss the area and perimeter of the rectangle, which are key concepts in many real-world situations, from the construction of buildings and houses to the making of clothes and packaging.
The concepts we will explore in this project interconnect with various disciplines, such as Physics (in the formation of images in mirrors, for example) and Arts (in the design of works that explore symmetry and the properties of the rectangle). In this way, we believe that this project will provide a deeper understanding of the importance of the rectangle and its applications in the real world.
Atividade Prática
"Rectangle in real life"
Project Objective
This project aims to provide a greater understanding of rectangles and their properties, applying them to everyday life and other disciplines. Students will develop practical mathematical skills, as well as collaboration and time management skills.
Project Description
In this project, student groups will be tasked with identifying, in real life and in other disciplines, where rectangles are present and applying theoretical concepts to solve practical problems related to them. In addition, students will need to produce a report, detailing everything they have learned and how they applied it in the project.
Necessary Materials
- Research material: such as math, physics, art books, and the internet.
- Measurement equipment: such as a ruler, tape measure.
- Documentation material: notebook for notes and a computer to write the report.
Project Step by Step
-
Research and Identification: Start by researching and identifying where rectangles are present in real life and in other disciplines. For example, in art frames, architecture, graphic design, packaging, and so on.
-
Selection and Measurements: Select some of these instances for further investigation. Measure the lengths of the sides and the angles to confirm if they are rectangles.
-
Calculations and Problem Solving: Use the Pythagorean Theorem to corroborate your measurements. Calculate the area and perimeter of these rectangles.
-
Connection with Other Disciplines: Discover how the concept of a rectangle is used in other disciplines, such as in the reflection of light in Physics, or in the arrangement of elements in a painting in Arts.
-
Report Production: Finally, consolidate all the information and experiences gained throughout the project into a report.
Project Deliverables
Groups must deliver a detailed report containing the following sections:
-
Introduction: Include an explanation about the rectangle, its importance, and application in real life. Also, tell the purpose of this project.
-
Development: Describe the theory used in the project, the activity that was carried out, the methodology used, and the results obtained. Which places were investigated? What were the measurements and calculations performed? How was the Pythagorean Theorem applied? How do rectangles connect with other disciplines?
-
Conclusion: Revisit the main points, mention the learnings and conclusions drawn from the project.
-
Bibliography: List all research sources during the project development.
The report should be both a record of what was done and an exposition of what was learned during the project. Think of it as a way to show the applicability of the rectangle concept in real life, and how it connects with other disciplines and concepts.
