Activity Suggestions

Activity Recommendations

Activity 1 - 📊 Instagram Infographic Creation

> Duration: 60 to 70 minutes

- Goal: Utilise digital tools to teach and apply the calculation of the triangle area, encouraging collaborative learning and student creativity.

- Deskripsi Activity: Students will design a digital infographic about the area of a triangle, using their newly acquired skills to explain how to compute the area. They'll utilise graphic design apps or even Instagram's functionalities to create and share their work.

- Instructions:

• Split the class into groups of up to 5 students.

• Each group should select a theme for their infographic related to calculating triangle areas (like architecture or bridge construction, for instance).

• Using graphic design apps like Canva or Adobe Spark, or Instagram's Stories feature, students create an infographic that educates others on calculating triangle areas with practical examples.

• Their infographic should include the area formula (base x height / 2), visual examples, and a brief textual explanation.

• Students need to share their infographic on Instagram with a previously agreed hashtag for everyone to view and comment on each other's work.

Activity 2 - 📱 Augmented Reality: Exploring Triangles in Nature

> Duration: 60 to 70 minutes

- Goal: Incorporate augmented reality tech into mathematical learning, enabling students to apply the triangle area formula in real-world situations.

- Deskripsi Activity: Students will employ augmented reality (AR) apps to discover and identify triangles in various structures found in nature and urban spaces. They'll calculate the area of these triangles right where they are, blending technology with maths.

- Instructions:

• Organise the class into groups of up to 5 students.

• Each group will use an AR app, like Google AR or ARuler, to spot triangles in structures around the school or in virtual images provided by the teacher.

• Post identification, students need to measure the base and height using the app's tools and calculate the area, employing the learnt formula.

• Groups should document their discoveries and calculations by taking photos or videos of the structures and the computed areas.

• Lastly, each group will present their findings to the class, explaining how they used AR tech to identify and calculate the area of the triangles.

Activity 3 - 🎮 Gamification: The Triangle Treasure Hunt
