Activity Suggestions

Activity Recommendations

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

> Duration: 60 - 70 minutes

- Goal: Encourage students to apply rectangle concepts to genuine situations while harnessing technology to take measurements and present their discoveries.

- Deskripsi Activity: Students will be grouped into small teams to embark on a 'treasure hunt' around the school, where they must locate and photograph items and structures that resemble rectangles. Using image editing apps on their phones, they will estimate the dimensions of the sides and angles of the rectangles they find. Later, they will compile their findings into a presentation using digital tools.

- Instructions:

• Divide the students into groups of up to 5.

• Explain that they need to identify at least five rectangular objects or structures around the school.

• Each group should take photos of the rectangles they discover.

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

• The groups should create a digital presentation (such as slides, a video, or any other creative format) showcasing photos and measurements of their found rectangles.

• Each group will subsequently present their findings to the class, detailing how they obtained the measurements and their insights regarding rectangles.

Activity 2 - The Geometric Influencer Challenge

> Duration: 60 - 70 minutes

- Goal: Encourage students to engage with mathematical concepts creatively through modern social media platforms, while cultivating their digital communication skills.

- Deskripsi Activity: Groups will craft a 'digital influencers' campaign aimed at explaining rectangle concepts. They should utilise social media platforms like Instagram or TikTok to create short, entertaining videos or posts that creatively explain the properties of rectangles, how to calculate measurements for sides and angles, and their everyday applications. The top videos will be showcased on the school's social media.

- Instructions:

• Split the students into groups of up to 5.

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

• Groups should develop digital content that conveys rectangle concepts through humour, storytelling, or practical illustrations.

• Content can comprise videos, stories, carousel posts, or various other creative formats.

• Groups will share their creations with the class, explaining how they leveraged the selected platform to elucidate rectangles.

• If feasible, the most impressive content will be posted on the school's social media.

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

> Duration: 60 - 70 minutes

- Goal: Enhance problem-solving and teamwork abilities whilst reinforcing the mathematical principles of rectangles in an interactive and enjoyable manner.

- Deskripsi Activity: Students will take part in a virtual 'escape room' challenge, where they must solve puzzles related to rectangles to move forward. Using a website or gamification platform, each group will tackle problems involving the calculation of sides and angles and apply previously learned concepts to decipher clues and 'escape' the game.

- Instructions:

• Arrange the students into groups of up to 5.

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

• Every group will access the link to the 'escape room' and begin solving puzzles.

• The puzzles will encompass calculations of sides and angles of rectangles as well as theoretical questions about their properties.

• Groups must answer all clues to successfully 'escape' the room.

• The first group to finish the challenge will be crowned the winner.

Feedback

Duration: (20 - 25 minutes)

The aim of this section of the lesson plan is to solidify the knowledge gained by students through experiential exchange and reflection. Group discussions and 360° feedback encourage a collaborative learning atmosphere where students acknowledge their successes, pinpoint improvement areas, and feel appreciated for their contributions, essential for ongoing development of mathematical and interpersonal abilities.

Group Discussion

Facilitate a group discussion with all students where groups share their learnings from the experience and their conclusions. Initiate the conversation with the following prompts:

Introduction: Ask students what they enjoyed most about the activity and give reasons. Sharing: Each group should present their findings briefly. Challenges: Discuss the main challenges faced during the activities. Application: Explore how students view the real-world application of rectangles after participating in the activity. Conclusion: Wrap up the conversation by underscoring the significance of understanding geometric shapes in reality and how technology can bolster this understanding.

Reflections

1. Has this activity altered your perspective on rectangles and their attributes? 2. How do you think digital tools aided (or hindered) problem-solving during the exercise? 3. Can you pinpoint other everyday scenarios where the concept of a rectangle is applicable?

Feedback 360º

Organise a 360° feedback session where each student receives input from their group mates regarding the activity. Guide the class to promote constructive and respectful feedback using the following script:

Every student should mention a positive aspect of each peer's collaboration during the activity. Every student should suggest an improvement area for a peer, while stressing the importance of respect and developmental focus. Conclude by asking each student to reflect on the feedback received and briefly state how they intend to utilise these suggestions to enhance their skills going forward.

Conclusion

Duration: (10 - 15 minutes)

The purpose of this section is to consolidate and celebrate the learning achieved, illustrating to students that their acquired knowledge holds genuine value in their lives and the modern world. By summarising the content engagingly and connecting it to real-life scenarios, we nurture ongoing interest and the utilitarian aspects of mathematical knowledge.
