The purpose of this stage of the lesson plan is to present the content to be learned to the students, providing an overview of the skills they should acquire. This will help guide teaching and learning, ensuring that students understand the core objectives and know what is expected of them by the end of the lesson.

Main Objectives

1. Recognize and identify the main quadrilaterals: square, rectangle, trapezoid, rhombus, and parallelogram.

2. Classify quadrilaterals based on the properties of their sides and angles.

3. Understand the specific characteristics of each type of quadrilateral, such as the rectangle, which has 4 equal angles and opposite sides that are equal and parallel.

Introduction

Duration: 10 - 15 minutes

The purpose of this stage of the lesson plan is to spark the students' interest in the theme and prepare them for the content that will be addressed throughout the lesson. By providing practical context and curiosities, the teacher creates a more engaging and meaningful learning environment, helping students connect with the material in a more personal and practical way.

Context

To start the lesson, explain to students that quadrilaterals are geometric figures very common in our daily lives. They appear in places like house windows, cell phone screens, tables, and even traffic signs. By understanding how to classify these quadrilaterals, students will be better able to identify these shapes in the world around them and comprehend their properties.

Curiosities

Did you know that engineers and architects use the principles of quadrilaterals to design stable and safe structures? For example, bridges and buildings are designed taking into account the properties of quadrilaterals to ensure that they are strong and balanced.

Development

Duration: 50 - 60 minutes

The purpose of this stage of the lesson plan is to provide a detailed and solid understanding of the different types of quadrilaterals. By exploring each type and their specific properties, students will be able to correctly identify and classify quadrilaterals. In addition, by solving practical questions, students will consolidate their knowledge and develop the analytical skills necessary to recognize these shapes in the world around them.

Covered Topics

1. Quadrilaterals : Explain that quadrilaterals are polygons with four sides. Give examples from everyday life, such as cell phone screens and windows. 2. Square : Detail that the square has four equal sides and four right angles (90 degrees). All sides are congruent and opposite sides are parallel. 3. Rectangle : Explain that the rectangle has four right angles, and the opposite sides are equal and parallel. 4. Rhombus : Describe that the rhombus has four equal sides, but the angles are not necessarily right. The opposite angles are equal. 5. Parallelogram ⬛: Inform that in the parallelogram, the opposite sides are equal and parallel, and the opposite angles are equal. 6. Trapezoid : Explain that the trapezoid has only one pair of parallel sides. There are different types of trapezoids, such as the isosceles trapezoid, where the non-parallel sides are equal.

Classroom Questions

1. What is the main difference between a square and a rectangle? 2. Describe the characteristics of a parallelogram. 3. How can you identify a trapezoid in your daily life?

Questions Discussion

Duration: 15 - 20 minutes

The purpose of this stage of the lesson plan is to review and consolidate the knowledge acquired by the students during the lesson. By discussing the answers to the questions, the teacher ensures that students correctly understood the content and can apply it in practical situations. This moment of reflection and engagement allows students to express their doubts and strengthen their skills in analysis and classification of quadrilaterals, promoting a deeper and more meaningful learning.

Discussion

• What is the main difference between a square and a rectangle? A square has four equal sides and four right angles (90 degrees), while a rectangle also has four right angles, but only the opposite sides are equal and parallel. Thus, all sides of a square are congruent, but in a rectangle, only the opposite sides are congruent.

• Describe the characteristics of a parallelogram. A parallelogram is a quadrilateral whose opposite sides are equal and parallel. In addition, the opposite angles of a parallelogram are also equal. Examples of parallelograms include the rectangle, rhombus, and square, which have these basic properties.

• How can you identify a trapezoid in your daily life? A trapezoid can be identified in daily life by observing that it has only one pair of parallel sides. Practical examples include some dining tables with non-parallel sides or certain types of house roofs. The isosceles trapezoid, for example, has equal non-parallel sides, which can be observed in various architectural structures.

Student Engagement

1. We can find squares and rectangles in many places. Who can give an example of where you saw these quadrilaterals today? 2. What is the importance of engineers knowing the properties of parallelograms when designing bridges and buildings? 3. Why is it useful for architects to understand the difference between a trapezoid and a rhombus? 4. How can understanding the different types of quadrilaterals help in daily activities, such as putting up wallpaper or building furniture?

Conclusion

Duration: 10 - 15 minutes

The purpose of this stage of the lesson plan is to review and consolidate the knowledge acquired by students, ensuring that they understand and retain the information presented. This final reflection moment helps to solidify concepts and connect theory with practical situations in everyday life.

Summary

• Quadrilaterals : Polygons with four sides, common in everyday life.
• Square : Four equal sides and four right angles (90 degrees).
• Rectangle : Four right angles, opposite sides equal and parallel.
• Rhombus : Four equal sides, opposite angles equal, but not necessarily right.
• Parallelogram ⬛: Opposite sides equal and parallel, opposite angles equal.
• Trapezoid : Only one pair of parallel sides, with different types, such as the isosceles.

The lesson connected theory with practice by using everyday examples to explain the different types of quadrilaterals. By relating geometric shapes to objects and structures in daily life, students were able to visualize and better understand the properties and classifications of quadrilaterals.

Understanding quadrilaterals is important for various fields, such as engineering and architecture, where knowledge of these shapes ensures the creation of stable and functional structures. Moreover, it is useful in everyday activities, such as assembling furniture and decorating spaces, where the precision of geometric shapes makes a difference.
