Activity Suggestions

Activity Recommendations

Activity 1 - 🔍 Congruence Detector: Spy Mission

> Duration: 60 - 70 minutes

- Goal: Help students recognize congruent shapes in everyday life while fostering teamwork and technological skills.

- Deskripsi Activity: Students will act as secret agents on a mission to discover 'clues' of congruent shapes hidden in various 'locations.' Each group will use their cell phones to tackle a mix of digital and physical challenges, identifying congruent shapes in everyday settings like architecture, clothing patterns, and logos.

- Instructions:

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

• Assign digital and physical missions to each group via a collaborative task app, such as Trello or Microsoft Teams, with hints to locate congruent shapes.

• Instruct students to document their findings with photos or videos and submit them in the app.

• For example: 'Find two logos from different brands that are congruent shapes.'

• Groups should then compare their findings with others and explain why the shapes are congruent.

• The teacher should circulate to assist groups, offering hints and clarifying uncertainties.

Activity 2 - 📱 Creating a Math TikTok

> Duration: 60 - 70 minutes

- Goal: Foster understanding of congruent shapes through engaging and creative methods via social media.

- Deskripsi Activity: In this activity, students will create short TikTok videos that explain congruent shapes. They’ll use their creativity and multimedia tools to showcase examples and explain their congruence.

- Instructions:

• Form groups of up to 5 students.

• Each group selects a theme, such as 'congruent shapes in nature' or 'in everyday objects.'

• Using cell phones, groups will film and edit a video up to 2 minutes long explaining congruent shapes and providing examples.

• Encourage the use of music, effects, and captions to enhance their videos.

• After editing, groups will post their videos on a class-created TikTok account and share the links.

• The teacher will view the videos and facilitate class discussions on each, highlighting strong points and areas for improvement.

Activity 3 - 🎮 Congruence Game: Build Your Game!

> Duration: 60 - 70 minutes

- Goal: Promote active learning of congruent shape concepts through digital game creation, enhancing programming and logic skills.

- Deskripsi Activity: Using a platform like Scratch, students will design a game where players aim to identify and capture congruent shapes. They will plan, program, and present their game to their classmates.

- Instructions:

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

• Explain that each group needs to create a game in Scratch featuring geometric shapes, where players must identify and capture congruent shapes for points.

• Provide a brief tutorial or guide students to video tutorials on using Scratch.

• Encourage groups to plan their game layout, decide on the rules, and design their shapes.

• Students will program the game, testing it with each other and making adjustments as necessary.

• Each group will then present their game to the class, sharing their learning experiences about congruent shapes.

Feedback

Duration: (15 - 20 minutes)

This stage wraps up the lesson reflectively and collaboratively, allowing students to consolidate their learnings through shared experiences and feedback. This closes the active learning loop while strengthening social and communication skills and nurturing a culture of continued collaboration.

Group Discussion

🔄 Group Discussion: Foster a collaborative environment where each group shares their experiences and hurdles faced during the activities. Use the following phrases to kick off the discussion:

Opening: “Now that we've wrapped up our missions, let’s share what we've learned. Each group has a few minutes to present their findings and how they discovered the congruent shapes.” Sharing: Allow each group to share, focusing on their methods and findings. Debate: Invite classmates to ask questions and comment on their peers’ presentations, creating a drive for a rich exchange of ideas and strategies.

Reflections

1. 📝 Question 1: What was the biggest hurdle you faced in identifying congruent shapes, and how did you tackle it? 🤔 2. 📝 Question 2: How did technology assist or complicate the tasks in identifying congruent shapes? 💻 3. 📝 Question 3: What insights did you gain about the real-life applications of congruent shapes from these activities? 🌍

Feedback 360º

🔄 360° Feedback: Conduct a constructive feedback session where every student receives respectful feedback from their peers. Set ground rules:

Be Specific: Give concrete examples of strengths or areas for improvement. Be Respectful: Use appropriate and encouraging language. Be Helpful: Offer practical and actionable suggestions. Be Balanced: Highlight what was done well alongside suggestions for enhancement.

Conclusion

Duration: (10 - 15 minutes)

🌟 Purpose: This final stage wraps up the lesson by reinforcing key points engagingly, connecting the material to real-world applications, and underlining its practical significance. Summarizing and reflecting on the day’s learnings helps solidify the knowledge gained and appreciate the value of congruent shapes in various everyday contexts.

Summary

🎉 Creative Summary: Think of congruent shapes as geometric clones - they may be rotated, but they always keep the same size and shape! 🌟 In our lesson, we delved into identifying these 'clones' through grids and our surroundings. We went undercover on a spy mission, crafted enjoyable TikTok videos, and even created our own games to cement our understanding! 🚀

World

🌍 Connection to the Modern World: Congruent shapes are all around us, appearing in brand logos, nature's symmetry, and contemporary architecture. Identifying these shapes helps us appreciate both the aesthetics and functionality of everyday objects while developing a keen eye for details that often go unnoticed in our digital age.

Applications

🏢 Importance for Daily Life: Recognizing congruent shapes is beneficial in numerous fields like design, fashion, advertising, and engineering. It sharpens our visual and spatial awareness, enabling the creation of more functional and visually appealing products. This skill is all the more crucial in our increasingly visual and digital environment.
