Activity Suggestions

Activity Recommendations

Activity 1 - 🎮 Augmented Reality Challenge: Building the Future!

> Duration: 60 - 70 minutes

- Goal: Enhance spatial visualization skills and understanding of orthogonal views through augmented reality technology, making learning dynamic and interactive.

- Deskripsi Activity: Students will utilize an augmented reality (AR) app to design and visualize orthogonal views of a building. This activity leverages AR technology, allowing them to see and manipulate different views of a 3D object while collaborating in teams.

- Instructions:

• Divide students into groups of up to 5.

• Each group should download and install a recommended AR app on their phones.

• Groups can choose a building or structure they like (like a house, a building, or a monument).

• Using the AR app, students will create a projection of their chosen building.

• Each group must identify and draw the orthogonal views (front, side, and top) of the building they designed.

• Students will calculate the area of the orthogonal views and the lateral surface area of the building.

• Lastly, groups should prepare a brief presentation (using slides or a video) to showcase their findings and explanations about the orthogonal views of their designed building.

Activity 2 - 📱 Instagram Storytelling: The Journey of the Cube!

> Duration: 60 - 70 minutes

- Goal: Foster understanding of orthogonal views through a modern and interactive approach, utilizing social media to engage students and encourage collaborative learning.

- Deskripsi Activity: Students will craft a series of Instagram posts narrating the 'journey' of a geometric figure (specifically, a cube) through its orthogonal views. They’ll incorporate photos, videos, and illustrations to explain the various orthogonal views and how to calculate their areas.

- Instructions:

• Split students into groups of up to 5.

• If they prefer, each group can create a new Instagram account for the project instead of using their personal accounts.

• Students must photograph or sketch a cube from different angles to represent the orthogonal views (front, side, and top).

• Each group will create a series of Instagram posts detailing each orthogonal view, complete with descriptions and area calculations.

• Students should use relevant hashtags (#OrthogonalView, #Geometry, #FunMath) and tag the school’s account, if applicable.

• At the end of the activity, groups should comment on each other's posts to encourage online discussion about the significance of orthogonal views and the insights gained.

Activity 3 - 🏗️ Digital Influencers: Building a Geometric City!

> Duration: 60 - 70 minutes

- Goal: Encourage creativity and practical application of knowledge of orthogonal views through video creation and digital modeling, leading to contextualized and collaborative learning.

- Deskripsi Activity: Students will step into the role of 'digital influencers' and create videos illustrating how to use orthogonal views to design and construct a city. They will work with design software or graphic applications to create models and simulations.

- Instructions:

• Form groups of up to 5 students.

• Choose a design tool recommended for the project, such as SketchUp or Tinkercad.

• Students will create and design a small city with various geometric structures (cubes, pyramids, etc.).

• Each group must draw and present the orthogonal views of at least three primary structures in their city.

• Students should record a video as if they were digital influencers, detailing the process of creating the city and how orthogonal views were applied.

• Finally, groups will share their videos on a designated platform (YouTube, Google Drive) and watch the others’ videos, leaving thoughtful comments and questions.

Feedback

Duration: 20 - 25 minutes

🎯 Purpose: The purpose of this stage is to create space for students to reflect on their learning, share experiences, and receive constructive feedback from classmates. This reinforces acquired knowledge, identifies improvement areas, and fosters the development of social and communication skills that are essential for successful collaboration.

Group Discussion

📢 Group Discussion: Lead a final discussion where students share their experiences and insights from the activities. Introduce the discussion with the following script:

1. Introduction: 'Now that we’ve finished the practical activities, let’s share what we learned. Who would like to kick things off by discussing what they gained and the challenges they faced in designing and calculating orthogonal views?'
2. Questions Addressed: 'What were the key discoveries from your group? How did orthogonal views aid in understanding spatial figures?'
3. Reflection: 'In what ways did digital technology, like AR and social media, support or hinder your learning about orthogonal views?'
4. Conclusion: 'Is there anyone who wants to share tips or strategies that proved useful during the activities?'

Reflections

1. ❓ Reflection Questions: 1. What was the toughest part of the activity? How did your group tackle that challenge? 2. 2. How did digital visualization (AR, apps) alter your comprehension of orthogonal views compared to traditional methods like pen and paper? 3. 3. How did group collaboration and the use of social media influence your learning?

Feedback 360º

🔄 360° Feedback: Instruct students to engage in a 360° feedback session. Each student should receive feedback from their group members regarding their contributions to the activities. Emphasize that the feedback should be constructive and respectful, focusing on:

1. What the peer excelled at.
2. An area for improvement.
3. A suggestion for future activities. Encourage phrases like 'I appreciated how you...', 'One area to work on is...', and 'Next time, perhaps you could...'
