Introduction

Duration: (15 - 20 minutes)

This phase aims to warm up students, sparking curiosity and interest in proportionality through relatable, everyday examples. By using their smart phones to seek out information, students take an active role in the learning process, bridging the gap between theory and their own lives. It’s also a great opportunity to introduce digital tools as a regular part of research and collaborative discussion.

Warming Up

We’ll kick off the lesson on proportionality by explaining that it’s a mathematical relationship between two or more quantities—where a change in one directly affects the other. Then, ask students to use their smart phones to find an interesting fact about proportionality in everyday life, whether it’s examples from cooking recipes, maps, scale drawings, or even in sports. Encourage them to share what they’ve discovered with the class.

Initial Thoughts

1. What does proportionality mean in your own words?

2. What are some examples of proportionality you came across in your research?

3. How do you see proportionality applied in everyday life?

4. Can you think of situations where an understanding of proportions might be useful?

5. Why is it important to grasp proportionality concepts for daily tasks like shopping or refuelling your car?

Development

Duration: 70 - 80 minutes

This phase provides practical, hands-on opportunities for students to apply the proportionality concepts they’ve learned. It engages students in a playful, technology-driven environment that fosters collaborative problem solving and strengthens their math, research, and presentation skills.

Activity Suggestions

Activity Recommendations

Activity 1 - 📷 Proportions and the Life of a Digital Influencer

> Duration: 60 - 70 minutes

- Goal: Apply the principles of proportionality in a modern and relatable context, while enhancing research and presentation skills.

- Deskripsi Activity: Students will simulate an ad campaign by creating a post on Instagram or TikTok, promoting a consumer product while incorporating proportionality concepts. They will need to calculate proportions to offer recommendations based on real data, such as relating product quantity to the number of followers reached.

- Instructions:

• Divide students into groups of up to 5 people.

• Have each group select a consumer product (e.g., cosmetics, food, accessories).

• Ask students to research real data involving proportions—for example, linking the quantity of product used to the number of people reached.

• Each group creates a post or a short video simulating an advertising campaign using social media like Instagram or TikTok.

• Ensure the post includes the calculated proportions and a brief explanation of how they arrived at these figures.

• Encourage the use of image or video editing apps available on their phones or computers to create attractive content.

• Have each group present their campaign to the class, explaining the maths behind the proportions used.

Activity 2 - 🎮 Gamifying Proportions: The Map Challenge

> Duration: 60 - 70 minutes

- Goal: Encourage hands-on application of proportionality concepts through a fun, collaborative activity, while using technology to support problem solving.

- Deskripsi Activity: Students will design a digital treasure hunt game that employs proportionality principles. Using digital tools, they’ll create clues that lead to a ‘treasure’ hidden around the school or nearby, with clues that involve calculating distances or volumes.

- Instructions:

• Divide students into groups of up to 5 people.

• Have each group choose a theme for their treasure hunt (e.g., space travel, jungle adventure).

• Use digital mapping tools like Google Maps to define points of interest around the school or in the neighbouring area.

• Instruct each group to create a series of clues that involve calculating proportions—such as the relationship between distances on the map and walking time.

• Have the clues entered into a digital document or a specific treasure hunt app like Actionbound or GooseChase.

• Then, have the groups swap their treasure hunts and work through the clues created by their peers.

• The group that completes the treasure hunt accurately and in the shortest time wins the challenge.

Activity 3 - 🍲 Proportions in the Kitchen: A Recipe for Success

> Duration: 60 - 70 minutes

- Goal: Put proportionality into practice in a real-world setting while encouraging practical math application and culinary creativity.

- Deskripsi Activity: Students will experiment by creating and adjusting cooking recipes, using proportionality concepts to scale ingredient amounts. They will use cooking apps and digital calculators to modify recipes based on different serving sizes.

- Instructions:

• Divide students into groups of up to 5 people.

• Have each group select a cooking recipe they’d like to try.

• Ask them to research the original recipe on reputable cooking websites or apps.

• Using proportionality, have students adjust the recipe for varying numbers of servings (for instance, doubling the recipe or cutting it in half).

• Ensure that all adjustments are calculated using digital calculators or specialized cooking apps.

• Have students simulate preparing their adjusted recipe through presentations or short explanatory videos.

• Each group then presents their revised recipe, discussing how they determined the correct proportions and the challenges they encountered.

Feedback

Duration: (20 - 25 minutes)

This stage offers a chance for reflection and the sharing of ideas, allowing students to reinforce and expand their learning through constructive dialogue. The group discussion nurtures critical reflection on their activities, while the 360° feedback fosters essential social and collaborative skills.

Group Discussion

Facilitate a whole-class discussion by inviting each group to share what they learned from their activity. Here’s a guide to structure the conversation:

1. Ask each group to briefly describe the activity they undertook (whether it was the ad campaign, treasure hunt, or recipe adjustment).
2. Encourage students to discuss the mathematical challenges they encountered while applying proportionality concepts.
3. Invite them to talk about how digital tools helped (or sometimes didn’t help) with their problem solving.
4. Ask if the hands-on experience changed or reinforced their understanding of proportionality.

Reflections

1. What were the biggest challenges you faced when applying proportionality in your activity? 2. How did digital tools influence the way you completed the tasks and understood the concepts? 3. In what ways did these practical activities deepen your understanding of proportionality?

Feedback 360º

Have students complete a 360° feedback session, where each member both provides and receives constructive feedback from their peers. Guide them to focus on aspects like:

1. Teamwork and overall participation.
2. Clarity in their explanations and presentations.
3. How effectively they applied mathematical concepts to their tasks.

Conclusion

Duration: (5 - 10 minutes)

Purpose: This final stage ties all the learning together, clearly linking mathematical concepts to real-life situations. It encourages students to see the direct benefits of what they’ve learned and motivates them to apply these skills in their daily lives.
