Introduction

Duration: 15 - 20 minutes

The purpose of this stage of the lesson plan is to establish a solid foundation for understanding translations of plane figures, demonstrating their practical application in real-world scenarios. By focusing on the development of practical skills, students will be better prepared to recognize and apply these concepts in everyday situations and in the job market, where understanding geometric transformations can be useful in various fields such as design, engineering, and architecture.

Contextualization

The translation of plane figures is a fundamental concept in geometry that finds applications in various real situations. For example, when we design a repeating pattern in fabrics or wallpapers, we are using translations. This concept is important not only in academic contexts but also in areas such as graphic design, engineering, and architecture, where it is essential to understand how to move figures without altering their shapes.

Curiosities and Market Connection

Did you know that video game designers use translations to smoothly move characters and objects throughout the environment? In addition, in civil engineering, translation is used to create repetitions of structural elements, ensuring that buildings and bridges are constructed efficiently. In architecture, translation is fundamental for creating aesthetic and functional patterns in building facades and interiors.

Initial Activity

To start the class, show a short 3-minute video that demonstrates how mosaic patterns are created using translations (for example, a video about Portuguese tiles). After the video, ask the following question to the students: 'How do you think the tiles were positioned to create this pattern?' Encourage them to discuss in small groups for 5 minutes and share their responses with the class.

Development

Duration: 40 - 45 minutes

The purpose of this stage of the lesson plan is to allow students to apply the concept of translation of plane figures in practical and creative activities, promoting a deeper and longer-lasting understanding. By the end, students will be able to recognize and perform translations in different contexts, developing essential skills for both everyday life and the job market.

Covered Topics

1. Concept of translation of plane figures
2. Identification of translated figures
3. Practical applications of translations in real life

Reflections on the Theme

Guide students to reflect on how the translation of plane figures can be observed in different everyday contexts, such as in floor patterns, video game design, and architecture. Encourage them to think about the importance of understanding these concepts to create and interpret patterns and movements in various professional areas.

Mini Challenge

Creating Patterns with Translations

Students will create their own patterns using translations of geometric figures on graph paper. This hands-on activity will help students visualize and apply the concept of translation in a creative and relevant context.

Instructions

1. Divide the students into groups of 3 to 4 people.
2. Distribute graph paper, rulers, and pencils to each group.
3. Ask the students to draw a simple geometric figure (such as a triangle) in one part of the paper.
4. Guide them to translate the drawn figure to different positions on the graph paper, creating a repeating pattern.
5. Encourage students to explore different directions and distances of translation to observe how the pattern changes.
6. After creating the pattern, ask each group to present their work and explain how they performed the translations.

Objective: Develop the ability to apply translations of plane figures to create repeating patterns, promoting a practical understanding of the concept of translation.

Duration: 25 - 30 minutes

Evaluation Exercises

1. Draw a triangle on graph paper and translate it 3 units to the right. Draw the new position of the triangle.
2. Draw a square and translate it 2 units up and 1 unit to the left. Draw the new position of the square.
3. Explain how translation can be used in creating patterns on wallpaper.

Conclusion

Duration: 10 - 15 minutes

The purpose of this stage of the lesson plan is to consolidate and reflect on the acquired knowledge, ensuring that students understand the importance and practical applications of the concept of translation of plane figures. By promoting a discussion and recapping the main points, students have the opportunity to internalize the content and recognize its relevance for the job market and everyday situations.

Discussion

Facilitate an open discussion with students about the main challenges faced during the creation of patterns with translations. Ask how they applied the theoretical concepts in practical activities and what strategies they used to overcome difficulties.
