Activity Suggestions

Activity Recommendations

Activity 1 - Designing the Dream House

> Duration: 60 to 70 minutes

- Goal: Practice calculating the areas of composite shapes in a realistic, digitally interactive context.

- Deskripsi Activity: Students will utilize an online interior design simulator to create a house layout. They will compute the total area of their floor plans based on basic shapes like triangles and rectangles.

- Instructions:

• Divide the students into groups of no more than 5.

• Each group should access an online interior design tool (such as Roomstyler or Floor Planner).

• Instruct students to design a floor plan using basic shapes (triangles and rectangles).

• Groups will calculate the total area of the floor plan, detailing the area of each shape used.

• Have the groups present their projects, explaining their calculations and totals.

Activity 2 - Architectural Influencers

> Duration: 60 to 70 minutes

- Goal: Leverage calculation skills and creativity to teach others about the area of composite shapes in a contemporary, digital setting.

- Deskripsi Activity: Students will create a 'story' style presentation for social media, explaining how to calculate the area of a composite shape found in a famous landmark (e.g., the Pyramids of Egypt, the Colosseum, etc.).

- Instructions:

• Divide the students into groups of no more than 5.

• Each group should select a famous building and find an image or diagram that can be broken down into basic shapes (triangles and rectangles).

• Students will use a social media story creation tool (like Instagram Stories or Canva) to craft a series of slides detailing the area calculation step-by-step.

• Slides should include images, calculations, and a narration explaining the process.

• Each group will present their 'story' to the class, mimicking a social media post.

Activity 3 - Geometric Treasure Hunt

> Duration: 60 to 70 minutes

- Goal: Engage students in a fun and interactive activity that reinforces the concepts studied, promoting collaboration and the effective use of digital tools.

- Deskripsi Activity: Students engage in a digital treasure hunt where they solve area calculation problems related to composite shapes to advance in the game.

- Instructions:

• Divide the students into groups of no more than 5.

• Each group should access a gamification platform (such as Kahoot or Google Forms) featuring a series of challenges associated with area calculations of composite shapes.

• The challenges will require students to solve problems in order to progress, with each success unlocking the next clue.

• The final goal is to solve all the problems and uncover the virtual 'treasure', which could be a digital certificate or a token of achievement.

• Emphasize teamwork to ensure every group member comprehends the problem-solving process.

Feedback

Duration: 15 to 20 minutes

This stage aims to solidify learning through reflection and sharing experiences. Group discussions enable students to identify strengths and areas for growth, while the 360° feedback encourages a supportive environment for mutual development. This process further emphasizes the significance of collaboration and the effective use of digital resources in learning.

Group Discussion

Encourage a group discussion where students share their learnings and observations from the activities. Suggest the following prompt to introduce the discussion:

🗣️ 'Now that we've all participated in various activities and calculated areas of composite shapes, let’s discuss our findings. Each group will have 5 minutes to present what they learned, any challenges they faced, and their solutions. Let’s begin with Group 1.'

Reflections

1. What were the most significant challenges faced when calculating the area of composite shapes? 2. How did digital tools help in solving the problems? 3. How could this experience be relevant to everyday situations or future math classes?

Feedback 360º

Guide students to conduct a 360° feedback session, ensuring that each student receives input from their peers. Offer these guidelines for constructive feedback:

🔄 Positive Feedback:

• Point out something specific that a peer excelled in during the activity (e.g., teamwork, calculation accuracy, innovative use of digital tools).

🔄 Areas for Improvement:

• Recommend an area for improvement, focusing on particular actions or skills (e.g., clearer communication, more attention to detail).

🔄 Respectful Feedback:

• Remind them to remain respectful and encouraging, fostering a positive and constructive atmosphere.
