Introduction

Duration: 10 - 15 minutes

This stage aims to activate learners' prior knowledge while prompting initial thoughts about symmetry, connecting the topic to real-life examples and their experiences. This will help engage learners and prepare them for the practical activities ahead.

Warming Up

Symmetry is a key concept in mathematics that we find all around us, from nature to the buildings we see. It refers to a perfect match of shapes and sizes on either side of a dividing line (axis of symmetry). To kick off the lesson, have learners use their phones to find a fascinating fact about symmetry in nature or architecture and share it with the class.

Initial Thoughts

1. What examples of symmetry did you discover in nature or among objects nearby?

2. How would you describe an axis of symmetry in your own words?

3. What geometric shapes can you name that exhibit symmetry?

4. In what ways can symmetry be beneficial in our daily lives?

5. Have you spotted symmetry in any captivating place? Where was it?

Development

Duration: 70 - 80 minutes

This stage of the lesson plan aims to give learners the chance to creatively and practically apply symmetry concepts via digital technology-based activities that resonate with their realities. The activities are designed to make learning dynamic and engaging, allowing students to explore and deepen their understanding in a fun and collaborative way.

Activity Suggestions

Activity Recommendations

Activity 1 - 📸 Symmetry on Social Media

> Duration: 60 - 70 minutes

- Goal: Identify and apply the concept of symmetry in everyday images, using digital tools to edit and highlight symmetrical features.

- Deskripsi Activity: In this activity, participants will investigate symmetry through social media by taking and editing photos that showcase various types of symmetry. They'll use photo editing apps on their phones to create visuals that emphasise axes of symmetry and reflective symmetries.

- Instructions:

• Group learners into teams of up to 5 members.

• Each team should select a theme for their photos (e.g., symmetry in nature, symmetry in buildings, symmetry in the human figure).

• Have learners snap photos that exemplify symmetry within their chosen themes.

• Using image editing tools (e.g., Instagram, Snapseed, VSCO), learners should identify and highlight the axes of symmetry in their images.

• Each group should create a brief presentation (it can be formatted as a social media post) explaining the type of symmetry they found and how they enhanced that symmetry through editing.

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

Activity 2 - 🇿🇦 Exploring Symmetries in Minecraft

> Duration: 60 - 70 minutes

- Goal: Apply concepts of symmetry in a virtual context, enhancing the ability to plan and create symmetrical structures.

- Deskripsi Activity: Learners will use the popular game Minecraft to build structures that embody different symmetry principles. They must design and construct buildings that clearly demonstrate vertical and horizontal axes of symmetry and reflective symmetries.

- Instructions:

• Form teams of up to 5 members.

• Each group is tasked with designing and building a structure in Minecraft that contains distinct examples of symmetry.

• Groups should sketch their designs on paper before starting in the game, outlining where the axes of symmetry will be.

• Using Minecraft's creative mode, learners will construct their designs as planned.

• Once built, students should take a screenshot of their structure and digitally indicate the axes of symmetry.

• Each group must present their structures and discuss the symmetry on a digital platform chosen by the teacher (e.g., Google Classroom, a WhatsApp group for the class).

Activity 3 - 🎮 Game Design: Creating Symmetrical Characters

> Duration: 60 - 70 minutes

- Goal: Deepen understanding of symmetry through character design, employing digital tools to flesh out and present symmetry concepts.

- Deskripsi Activity: Students will play the role of game designers, crafting characters that follow symmetry guidelines. They'll use online graphic design tools to create characters that display clear and striking symmetries.

- Instructions:

• Split learners into teams of up to 5 members.

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

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

• As they draw, learners must identify and highlight the axes of symmetry used in their character's design.

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

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

Feedback

Duration: 15 - 20 minutes

This stage is meant to allow students to reflect on what they gained, share their discoveries, and receive constructive feedback from peers. This process helps consolidate their learning and fosters a collaborative learning environment where everyone can benefit from each other's insights.

Group Discussion

Encourage a discussion where each group shares its experiences and findings from the activities. A possible script to start the discussion could be: 'Now that all groups have completed their activities, let's share what each one discovered. I want each group to share a bit about what they learned about symmetry, how they employed digital tools to identify and enhance symmetry, and any challenges they faced during the process.'

Reflections

1. What did you find most intriguing while exploring symmetries in different contexts? 2. How did digital tools assist you in gaining a clearer understanding of symmetry? 3. What challenges did you face, and how did you tackle them throughout the activities?

Feedback 360º

Conduct a round of feedback where each learner receives insights from their group mates. Instruct students to give constructive and respectful feedback, highlighting strengths and areas for improvement. Start this phase by saying: 'Now, each of you will receive feedback from your group mates. Remember to be respectful, highlighting both strengths and suggestions for improvement. This is a chance for everyone to learn from one another's experiences.'

Conclusion

Duration: 10 - 15 minutes

✍️ Purpose: This section aims to summarise and solidify the core concepts learned about symmetry, depicting its practical applications and significance in today’s world. Additionally, it seeks to link theory to real-life situations, inspiring learners to consciously and creatively apply the knowledge they've gained in their everyday experiences.

Summary

🔍 Fun Summary: Let's wrap things up with a bang! Today, we delved into the amazing world of symmetry! We learned that symmetry happens when something mirrors itself on either side of an axis – it’s almost like a magic mirror! We spotted this in nature, architecture, and even our beloved games. We dived into symmetry axes, both vertical and horizontal, and examined reflective symmetry. It truly was an adventure through social media, Minecraft builds, and character creation. 🚀✨

World

🌍 In Today's World: Symmetry isn’t just a dull mathematical idea; it’s all around us! From the perfect symmetry in a butterfly's wings to the sleek design of modern buildings. Even on social media, where filters often play with symmetry to create stunning visuals. Understanding symmetry enhances our appreciation of the aesthetic, architectural, and natural realms surrounding us. 🤩🏙️

Applications

🔌 Applications in Daily Life: Symmetry holds significant importance across various fields. In art, it brings harmony; in architecture, it ensures structural stability; and even in technology, like the user interface design we encounter daily in our favourite apps. Grasping symmetry not only refines our critical analysis but is also essential for innovation in multiple domains. 🎨🏗️📱
