Warming Up

Symmetry is a key concept in mathematics that can be seen in countless forms around us, from nature to human-made structures. It involves the exact correspondence of shapes and sizes on opposite sides of a dividing line (axis of symmetry). To kick off the class, have students use their phones to find an intriguing fact about symmetry in nature or architecture and share it with the class.

Initial Thoughts

1. What examples of symmetry did you observe in nature or in objects around you?

2. What is an axis of symmetry? Can you describe it in your own words?

3. What geometric shapes do you know that exhibit symmetry?

4. How can symmetry be useful in our daily lives?

5. Have you encountered symmetry in any interesting locations? Where?

Development

Duration: 70 - 80 minutes

The intention of this stage of the lesson plan is to provide students with a chance to creatively and practically apply the concepts of symmetry through activities that leverage digital technologies and are contextualized with their realities. These activities aim to make learning dynamic and engaging, allowing students to explore and deepen their knowledge in a playful and collaborative manner.

Activity Suggestions

Activity Recommendations

Activity 1 - 📸 Symmetry on Social Media

> Duration: 60 - 70 minutes

- Goal: Recognize and apply the concept of symmetry in everyday images, utilizing digital tools to edit and enhance symmetrical elements.

- Deskripsi Activity: In this activity, students will delve into symmetry through social media by taking and editing photos that showcase different types of symmetry. They will utilize image editing tools available on their devices to create visual compositions that highlight axes of symmetry and reflective symmetries.

- Instructions:

• Divide the students into groups of up to 5.

• Each group should select a theme for their photos (e.g., symmetry in nature, symmetry in architecture, symmetry in the human body).

• Ask students to capture photographs that exemplify symmetry in their chosen themes.

• Using image editing apps (e.g., Instagram, Snapseed, VSCO), students should identify and mark the axes of symmetry in their photos.

• Each group should create a concise presentation (it can take the form of a social media post) explaining the type of symmetry they discovered and how they enhanced it through editing.

• The posts should be shared on a digital platform chosen by the teacher (e.g., Google Classroom, a WhatsApp group for the class).

Activity 2 - 🏰 Exploring Symmetries in Minecraft

> Duration: 60 - 70 minutes

- Goal: Apply symmetry concepts in a virtual setting, honing the ability to plan and execute symmetrical constructions.

- Deskripsi Activity: Students will engage with the well-known game Minecraft to construct structures that embody different principles of symmetry. They need to plan and execute builds that clearly demonstrate vertical and horizontal axes of symmetry, as well as reflective symmetries.

- Instructions:

• Divide the students into groups of up to 5.

• Each group is tasked with designing and building a structure in Minecraft that clearly showcases symmetry.

• Groups should sketch their designs on paper beforehand, pinpointing where the axes of symmetry will exist.

• Using Minecraft's creative mode, students should assemble their structures according to their plans.

• After construction, students should capture a screenshot of the structure and digitally mark the axes of symmetry.

• Each group must share their creations and explanations about the symmetry on a digital platform selected by the teacher (e.g., Google Classroom, a WhatsApp group for the class).

Activity 3 - 🎮 Game Design: Designing Symmetrical Characters

> Duration: 60 - 70 minutes

- Goal: Develop understanding of symmetry through the creation of game characters, utilizing digital tools to design and present concepts of symmetry.

- Deskripsi Activity: Students will step into the shoes of game designers, creating characters that follow symmetry rules. By using online graphic design tools, they should craft characters that feature clear and striking symmetries.

- Instructions:

• Divide the students into groups of up to 5.

• Each group should brainstorm and plan a character for a game, focusing on symmetry in the design.

• Students should use online graphic design tools (e.g., Canva, Pixlr, GIMP) to illustrate their characters.

• During the illustration process, students must identify and mark the axes of symmetry employed in their character's design.

• Each group should assemble a brief presentation in slide or video format, explaining how they incorporated symmetry into their character design.

• The designs and presentations should be shared on a digital platform determined by the teacher (e.g., Google Classroom, a WhatsApp group for the class).

Feedback

Duration: 15 - 20 minutes

The purpose of this stage is to allow students to reflect on what they learned, share their discoveries, and receive constructive feedback from their peers. This will help consolidate the knowledge gained while fostering a collaborative learning environment where everyone can learn from each other’s experiences.

Group Discussion

Encourage a group discussion where each group shares their experiences and insights from the activities they engaged in. A possible script to launch the discussion could be: 'Now that all groups have wrapped up their activities, let’s share what each team discovered. I’d like each group to touch on what they learned about symmetry, how they utilized digital tools to identify and enhance symmetry, and any challenges you faced along the way.'

Reflections

1. What did you find most captivating while exploring symmetries in different contexts? 2. How did digital tools aid in your understanding of the concept of symmetry? 3. What challenges did you run into, and how did you tackle them during the activities?

Feedback 360º

Conduct a 360° feedback session, where each student receives input from their groupmates. Instruct students to provide constructive and respectful feedback, showcasing strengths and offering suggestions for improvement. Start this step by explaining: 'Now, each of you will receive feedback from your peers. Remember to be constructive and aim to highlight both strengths and suggestions for improvement. Let’s use this chance for everyone to gain from each other's experiences.'

Conclusion

Duration: 10 - 15 minutes

✍ Purpose: The aim of this stage is to summarize and consolidate the key concepts learned about symmetry, emphasizing its practical applications and relevance in today's world. Additionally, it seeks to bridge theory with real-life situations, motivating students to apply the knowledge gained in their daily lives in a thoughtful and inventive way.

Summary

🔍 Captivating Summary: Let’s wrap it up with flair! Today, we ventured into the amazing realm of symmetry! We learned that symmetry is when something mirrors itself on both sides of an axis – it's akin to a magical reflection! We spotted this in nature, in architecture, and even in our beloved games. We explored symmetry axes, both vertical and horizontal, and delved into reflective symmetry. It was a true journey through the lenses of social media, Minecraft builds, and character creation. 🚀✨

World

🌍 In Today's World: Symmetry isn't just a dull mathematical concept; it's everywhere we look! From the perfect symmetry of a butterfly's wings to the sleek design of contemporary buildings. Even in social media, where filters and photo edits often employ symmetry for stunning effects. Understanding symmetry enhances our appreciation for the aesthetic, architectural, and natural wonders surrounding us. 🦋🏢

Applications

🛠️ Applications in Daily Life: Symmetry plays a significant role across various fields. In art, it enhances harmony; in architecture, it contributes to the stability of structures; and even in technology, like user interface (UI) design that we interact with daily. Grasping symmetry sharpens our critical perspective and is essential for creativity and innovation in diverse sectors. 🎨🏗️📱
