Activity 2 - Angle Detectives 🔍🕵️

> Duration: (60 - 70 minutes)

- Goal: Apply angle classification knowledge to the real world, promoting observation and the effective use of technology to document discoveries.

- Deskripsi Activity: Students will turn into 'detectives' and use their phones to seek out and photograph angles in various locations around the school or from online images if needed. Each group will be given a list of angle types (acute, right, obtuse, and straight) to locate and classify. The photos will be assembled into a collaborative slide presentation using Google Slides or Canva, and every group will explain their findings to the class.

- Instructions:

• Form groups of up to 5 students.

• Provide a list of the angle types to be found: acute, right, obtuse, and straight.

• Have each group use their phones to capture pictures of the angles found around the school or from online images.

• Ask students to create a shared slide presentation highlighting the photos and classifications of the angles.

• Each group will share their findings, discussing where each angle was found and how they classified them.

Activity 3 - Math Influencers 📸🤳

> Duration: (60 - 70 minutes)

- Goal: Encourage creative expression and apply angle knowledge in a fresh and engaging way, harnessing social media to boost learning.

- Deskripsi Activity: Students will form groups to create a brief video on TikTok or Instagram Reels, creatively explaining angle classification. They can utilize graphics, cartoons, skits, or any other visual aids to enhance the video's appeal. The videos will be shown to the class, and the group with the most informative and creative video will earn a prize.

- Instructions:

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

• Explain that each group must produce a short video on TikTok or Instagram Reels about angle classification.

• Support students in using visual aids and creativity to convey the concepts.

• Give groups time to plan and record their videos.

• Once their videos are recorded, have each group share their creation with the class.

• Conduct a vote to determine the most creative and informative video, awarding a prize to the winning group.

Feedback

Duration: (15 - 20 minutes)

This stage aims to reinforce learning through sharing experiences and reflections, allowing students to collaboratively identify and address challenges. Group discussions stimulate critical thinking and teamwork, while comprehensive feedback enhances communication skills and promotes a respectful learning environment.

Group Discussion

Initiate the group discussion by underscoring the importance of working together and sharing insights. Explain that every group will have the chance to present their experiences and conclusions from the activities. Use this script to guide the discussion:

1. Introduction: 'Now that we've wrapped up our activities, let’s share what we’ve learned. Each group will have a few minutes to present their discoveries and reflections.'
2. Presentations: 'I’d like each group to start by discussing their activities, any challenges they faced, and how they addressed them. Who would like to start?'
3. Open Discussion: 'After the presentations, we’ll hold an open discussion on the different experiences shared. Feel free to ask questions and provide comments on the presentations from other groups.'
4. Conclusion: 'To sum up, let’s reflect together on how this experience enhanced our understanding of angles and how we might apply this knowledge in other subjects or daily situations.'

Reflections

1. What was the toughest challenge your group encountered during the activities and how did you manage it? 2. In what ways did the activities help solidify your understanding of angle classification? 3. How do you think using technology and social media impacted learning in this lesson?

Feedback 360º

Guide students to provide comprehensive feedback at the end of the discussion. Each student should offer constructive and respectful critiques to their peers. Use these guidelines to assist students:

1. Be Specific: Clearly articulate what worked well and what could be improved.
2. Be Respectful: Frame your feedback kindly and constructively.
3. Be Constructive: Offer practical suggestions for enhancement.

Feedback example: 'I appreciated how you used real-life examples to explain angles. I think including more visuals could make it even clearer for everyone.'

Conclusion

Duration: (5 - 10 minutes)

🚀 Purpose: This stage aims to consolidate learning in a light-hearted manner, emphasizing the importance of the knowledge gained. By linking theory with everyday practice and the digital sphere, we make learning more meaningful and applicable, inspiring students to see math as a valuable tool in their everyday lives.

Summary

🎉 Recapping the Angle Adventure: Picture every angle as a character at a lively party! The acute angles are the lively ones, always ready to dance! The right angles are the party's bouncers, standing firm and making sure everything stays in order. The obtuse angles take their time, more laid-back and enjoying the bash at a leisurely pace. Lastly, we have the straight angles, paving the way for everyone and keeping the party running smoothly.

World

🌐 Connection to the Modern World: Nowadays, technology and geometry are often intertwined. From video game design to modern architecture, and even in the photos we snap and edit on social media, angles are part of our daily lives. Understanding how to identify and classify them helps us make better choices both visually and technically in the digital realm.

Applications

📌 Applications in Daily Life: Knowing how to classify angles isn't just a classroom task; it’s a practical skill. Architects and engineers rely on this knowledge to create safe and practical structures. Graphic designers apply it to produce impactful visuals. Even photographers and filmmakers use these principles to achieve harmony and aesthetics in their images.
