Activity 1 - Designing Cities on Social Media

> Duration: 60 - 70 minutes

- Goal: Help students hone their area calculation skills and leverage social media platforms to share knowledge.

- Deskripsi Activity: Students will be tasked with creating a small city using a grid. After outlining the areas of various structures (houses, parks, buildings, etc.), they will calculate the area of each shape. Then, utilizing social media platforms like Instagram or TikTok, each group will produce a post or video explaining how they calculated the areas and the real-world importance of this skill.

- Instructions:

• Divide the students into groups of up to 5.

• Distribute a sheet of grid paper to each group.

• Ask the students to design a small city with various geometric shapes including houses (rectangles), parks (squares), and buildings (squares and rectangles).

• Students must calculate the area of each shape they create.

• Each group should use their phones to post on Instagram or create a TikTok video explaining their area calculation process and discussing its significance.

• Groups will then share their posts/videos with the class and discuss their learnings.

Activity 2 - Math Digital Influencers

> Duration: 60 - 70 minutes

- Goal: Foster creativity and communication skills in students by having them produce educational digital content.

- Deskripsi Activity: Each group will become a digital influencer team, responsible for creating a tutorial video for YouTube about calculating the area of shapes on a grid. They'll be encouraged to use video editing applications to make their content more engaging and interactive.

- Instructions:

• Divide the students into groups of up to 5.

• Provide a sheet of grid paper to each group and access to a computer with internet.

• Students should sketch several figures on the grid and find their respective areas.

• Each group must plan and record a tutorial video explaining their methods for calculating the areas of the shapes on the grid.

• Encourage the use of video editing apps to add special effects and make the tutorial more captivating.

- Instructions:

• Divide the students into groups of up to 5.

• Guide students to download a geolocation and augmented reality app (e.g., Actionbound, Seek by iNaturalist) on their phones.

• Create a set of clues and virtual or physical spots where students will discover geometric shapes drawn on grids.

• Students should find these shapes, compute their areas, and enter their answers in the app to move forward in the game.

• Set up a final challenge where the groups need to calculate the area of a complex figure to successfully finish the game.

• Groups that complete the game will discuss their strategies and solutions with the class.
