Warming Up

To start the lesson on rectangles, briefly explain the concept of a rectangle, highlighting that it is a quadrilateral with four right angles. Ask students to use their cell phones to search for an interesting fact about rectangles, such as where they are found in everyday life, historical or scientific curiosities, and share with the class. This action will not only engage them with the use of technology but will also contextualize the topic in a practical way that is close to their reality.

Initial Reflections

1. What differentiates a rectangle from other quadrilaterals?

2. What are the properties of angles in a rectangle?

3. How can you apply the concept of rectangles in everyday situations?

4. Did anyone find an interesting fact about the application of rectangles in areas like architecture or design?

Development

Duration: 65 - 75 minutes

The purpose of this stage of the lesson plan is to provide students with engaging and practical opportunities to apply rectangle concepts in real contexts using contemporary digital tools. These activities are designed to foster creativity, collaboration, and the use of technology, making learning more meaningful and aligned with their daily realities.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Rectangles in the City - A Digital Treasure Hunt

> Duration: 60 - 70 minutes

- Objective: Encourage students to apply rectangle concepts in real-life and everyday situations while using technology to take measurements and present their findings.

- Description: Students will be divided into small groups and will carry out a 'treasure hunt' around the school, where they must find and photograph objects and structures in the shape of a rectangle. Using image editing apps on their phones, they will calculate the approximate measurements of the sides and angles of the rectangles found. They will then create a presentation using digital tools to share their findings.

- Instructions:

• Divide the students into groups of up to 5 people.

• Explain that they will have to find at least five objects or structures in the shape of a rectangle around the school.

• Each group must take photos of the rectangles found.

• Using image editing apps, groups should measure the sides and angles of the rectangles.

• Groups should produce a digital presentation (slide, video, or another creative format) with the photos and measurements of the rectangles found.

• Each group will present their findings to the class, explaining how they made the measurements and what they discovered about the rectangles.

Activity 2 - The Geometric Influencers Challenge

> Duration: 60 - 70 minutes

- Objective: Encourage students to explore mathematical concepts creatively using modern social media platforms and develop digital communication skills.

- Description: The groups must create a 'digital influencer' campaign to explain rectangle concepts. They should use social media like Instagram or TikTok to create short videos or posts that explain, in a fun and creative way, the characteristics of rectangles, how to calculate side lengths and angles, and practical applications in everyday life. The best videos will be shared on the school's social media.

- Instructions:

• Divide the students into groups of up to 5 people.

• Each group will choose a social media platform (Instagram, TikTok, etc.) to create their posts.

• Groups should create digital content that explains rectangle concepts, using humor, storytelling, or practical examples.

• Content may include videos, stories, carousel posts, or another creative format.

• Groups will have to present their creations to the class, explaining how they used the chosen platform to teach about rectangles.

• If possible, the best content will be shared on the school's social media.

Activity 3 - Virtual Escape Room - The Mystery of the Missing Rectangle

> Duration: 60 - 70 minutes

- Objective: Develop problem-solving and teamwork skills while solidifying mathematical concepts of rectangles in an engaging and playful way.

- Description: Students will participate in a virtual 'escape room' challenge, where they need to solve riddles related to rectangles to advance. Using a website or gamification platform, each group will solve problems regarding the calculation of sides and angles, and apply learned concepts to decipher clues and 'escape' the game.

- Instructions:

• Divide the students into groups of up to 5 people.

• Explain the concept of the virtual 'escape room' and how they will use the chosen platform (e.g., Google Forms, Kahoot, BreakoutEDU).

• Each group should access the link of the 'escape room' and start solving the riddles.

• The riddles will involve calculations of side lengths and angles of rectangles, as well as theoretical questions about their properties.

• Groups should answer and decipher all clues to successfully 'escape' the room.

• The group that completes the challenge first will be declared the winner.

Feedback

Duration: (20 - 25 minutes)

The purpose of this stage of the lesson plan is to consolidate the knowledge gained by students through the exchange of experiences and reflections. Group discussion and 360° feedback promote a collaborative learning environment where students can recognize their achievements, identify areas for improvement, and feel valued for their contributions, which is essential for the continuous development of mathematical and interpersonal skills.

Group Discussion

Promote a group discussion with all students, where groups share what they learned from the experience and their conclusions. To start this discussion, follow the script below:

Introduction: Ask students what they liked most about the activity and why. Sharing: Ask each group to present their findings briefly. Challenges: Ask what the main challenges encountered during the activities were. Application: Ask how they perceive the application of the rectangle concept in everyday life after the activity. Conclusion: Closing the discussion, highlight the importance of understanding geometric figures in the real world and how technology can assist in this process.

Reflections

1. How did carrying out the activity change your understanding of rectangles and their properties? 2. In what way do you think digital tools helped (or hindered) the solution of the presented problems? 3. Can you identify other everyday situations where the concept of a rectangle can be applied?

360° Feedback

Conduct a 360° feedback stage, where each student receives feedback from other students in their group regarding the activity. Guide the class to ensure that feedback is constructive and respectful, using the following script:

Each student should mention one positive point regarding each colleague's collaboration during the activity. Each student should suggest one area for improvement for their colleague. Remind everyone to do this respectfully and focused on development. End by asking each student to reflect on the feedback received and briefly comment on how they plan to use these suggestions to improve their future skills.

Conclusion

Duration: (10 - 15 minutes)

The purpose of this stage is to consolidate and celebrate learning, showing students that what they have learned has real value in their lives and in today's world. By summarizing content in an animated way and connecting it with reality, we encourage continued interest and practical applicability of mathematical knowledge.

Summary

Congratulations, Digital Explorers! 🌟 Today, we navigated the world of rectangles: shapes with four sides and four right angles. You hunted for rectangles around the school, measured, calculated, and even created campaigns for 'math influencers.' And how cool, you even solved riddles in a virtual escape room! Who would have thought that math could be so interactive and fun, right?

World Connection

Our world is full of rectangles: from the screens of our smartphones to the pages of books, through traffic signs, and even on movie screens. Understanding rectangles is like having a key to unlock many geometric secrets that surround us in our daily lives. Moreover, by using technology and social media to understand and teach these concepts, we are adopting the modern dynamics of communication and learning, making knowledge more accessible and engaging.

Practical Application

Understanding rectangles goes beyond the classroom; it helps in building environments, product design, and even in art and architecture. Knowing how to identify and calculate their properties makes everyday tasks, like rearranging a room or creating a presentation layout, more efficient and creative.
