Introduction

Duration: 10 - 15 minutes

This stage aims to introduce students to the world of quadrilaterals, emphasizing the importance of recognizing and classifying different geometric shapes. This knowledge is fundamental not only for mathematics but also for various practical applications in the job market, such as design, engineering, and architecture. Through the development of practical and experimental skills, students prepare to apply this knowledge in real contexts, promoting meaningful learning and connecting theory to practice.

Contextualization

Quadrilaterals are present in our daily lives in various forms, from the screen of our phone to the structure of the buildings where we live and work. Understanding and recognizing these geometric shapes is essential as they form the basis of many constructions and designs that surround us. In this lesson, we will explore the different characteristics of quadrilaterals, learning to identify and classify them based on their properties.

Curiosities and Market Connection

Did you know that quadrilaterals are fundamental in architecture and graphic design? For example, architects use squares and rectangles to plan buildings and interiors, ensuring that structures are stable and functional. In graphic design, quadrilaterals are used to create harmonious layouts in advertising pieces and digital interfaces. Additionally, civil engineers employ knowledge about quadrilaterals to develop bridges and streets, ensuring safety and efficiency in constructions.

Initial Activity

To start the lesson, present a short video (3-5 minutes) about the application of quadrilaterals in modern architecture. After the video, ask a provoking question: How do you think understanding quadrilaterals can influence the design of a sustainable building? Ask students to share their ideas in a brief discussion.

Development

Duration: 45 - 50 minutes

This stage aims to deepen students' knowledge about quadrilaterals, allowing them to apply what they have learned in a practical and collaborative manner. Building models and solving fixation exercises help consolidate understanding of geometric properties, promoting meaningful learning applicable to everyday contexts and the job market.

Covered Topics

1. Definition and characteristics of the main quadrilaterals: square, rectangle, trapezoid, rhombus, and parallelogram.
2. Properties of the sides and angles of quadrilaterals.
3. Practical applications of quadrilaterals in the job market.

Reflections on the Theme

Guide a discussion with students about how different quadrilaterals can be found in our daily lives and how their properties can influence their application in different fields, such as engineering, design, and architecture. Ask them how the knowledge of these shapes can be useful in professions involving construction and design.

Mini Challenge

Build Your Own Quadrilateral

Students will be divided into groups and challenged to build three-dimensional models of different quadrilaterals using materials such as popsicle sticks, hot glue, and cardboard. Each group must choose one type of quadrilateral (square, rectangle, trapezoid, rhombus, or parallelogram) and create a model that highlights its main characteristics.

Instructions

1. Divide students into groups of 3-4 people.
2. Distribute the necessary materials to each group: popsicle sticks, hot glue, cardboard, scissors, and rulers.
3. Ask each group to choose a type of quadrilateral to build.
4. Encourage groups to sketch a draft of the chosen quadrilateral before starting construction.
5. Guide the groups during construction, helping them identify and highlight the main characteristics of the quadrilateral.
6. After completion, each group should present its model to the class, explaining the properties of the quadrilateral and how it was constructed.

Objective: Develop practical skills in building geometric models and apply theoretical knowledge about quadrilaterals in a concrete and collaborative way.

Duration: 25 - 30 minutes

Evaluation Exercises

1. Ask students to draw the five types of quadrilaterals and identify their main characteristics (parallel sides, equal angles, etc.).
2. Propose an exercise where students must classify a series of geometric figures as squares, rectangles, trapezoids, rhombuses, or parallelograms, justifying their answers.
3. Guide students to solve practical problems where they need to apply knowledge of quadrilaterals, such as calculating areas and perimeters of figures composed of different quadrilaterals.

Conclusion

Duration: 10 - 15 minutes

This stage aims to consolidate the learning from the lesson, allowing students to reflect on what they have learned and how this can be applied in practical situations. Through recapping the content and discussing the activities carried out, students can better internalize the information and understand the relevance of the knowledge acquired for their daily lives and future careers.

Discussion

Start a discussion with students about the activities carried out during the lesson. Ask how building the three-dimensional models helped them better understand the characteristics of quadrilaterals. Encourage them to share their reflections on the relevance of knowing these geometric shapes in professions such as engineering, architecture, and design. Question them about the challenges they faced and how they overcame them, and ask them to comment on the fixation exercises and how they contributed to solidifying the knowledge acquired.

Summary

Summarize the main content presented in the lesson, highlighting the types of quadrilaterals (square, rectangle, trapezoid, rhombus, and parallelogram) and their characteristics, such as parallel sides and equal angles. Recap the importance of recognizing and classifying quadrilaterals and how this connects to various fields of knowledge and the job market.

Closing

Explain how the lesson connected theory and practice, showing that knowledge of quadrilaterals is not just an academic matter but has significant practical applications in daily life and various professions. Emphasize the importance of continuous learning and applying knowledge in real contexts. Finally, thank the students for their participation and encourage them to continue exploring the world of geometry.
