Activity Suggestions

Activity Recommendations

Activity 1 - Digital Influencers and Linear Functions 🚀

> Duration: 60 to 70 minutes

- Goal: Utilise the concept of linear functions in a realistic scenario, like forecasting the follower growth of a digital influencer. Enhance research, data analysis, graphing, and communication skills.

- Deskripsi Activity: Students will craft a fictional digital influencer's profile and employ linear functions to forecast follower growth over time. This activity merges storytelling with maths, making learning enjoyable and relatable.

- Instructions:

• Split students into groups of up to 5 members.

• Each group will build a detailed profile of a fictional digital influencer, covering name, market niche (fashion, tech, education, etc.), and main platform (Instagram, YouTube, TikTok).

• Students should investigate follower growth trends on various platforms and gather real data.

• Based on the gathered data, each group will develop a linear function representing follower growth over time (y = ax + b).

• Groups will plot a graph on the Cartesian plane illustrating the follower growth function over a set timeframe (for instance, 6 months).

• Every group will present their influencer profile and growth graph to the class.

• During the presentation, groups must clarify how they derived the linear function and interpret the intercepts on the x and y axes.

Activity 2 - Social Media Challenge: Linear Functions in Action 📊

> Duration: 60 to 70 minutes

- Goal: Develop the ability to apply linear functions to everyday situations. Foster skills for data interpretation, table organisation, graphing, and teamwork.

- Deskripsi Activity: Students will take part in a challenge where they will apply linear functions to solve everyday issues presented as social media posts. The activity involves data interpretation and graph creation to address the challenges.

- Instructions:

• Organise students into groups of up to 5 members.

• Distribute a set of fictional social media posts to each group, where each post contains a practical problem solvable via linear functions. For example: 'Predicting household energy use based on past bills.'

• Students must identify the linear function in each problem and present the data in a table.

• Each group will graph the identified function on the Cartesian plane.

• Groups will prepare a presentation detailing their problem-solving process, interpreting the intercepts on the x and y axes.

• Finally, the groups will share their solutions with the class through brief presentations.

Activity 3 - Functions Game: 'The Line Master' 🎮

> Duration: 60 to 70 minutes

- Goal: Engage students through interactive gaming, fostering the learning of linear functions in a fun and engaging manner. Develop problem-solving, teamwork, and critical thinking skills.

- Deskripsi Activity: Students will engage in a digital game where they will compete to become 'Line Masters'. They will tackle various mathematical challenges using linear functions to advance in the game and accumulate points.

- Instructions:

• Split students into groups of up to 5 members.

• Each group will access an interactive digital game designed by the teacher. The game features distinct levels with challenges related to linear functions.

• Students will solve problems involving value tables, identifying linear functions, and graphing on the Cartesian plane.

• As groups complete challenges, they earn points and progress to more complex levels.

• The game will include 'pause' moments where the teacher will intervene to discuss solutions and clarify doubts.

• At the end, the group with the highest score will be crowned 'The Line Master' and receive a small symbolic prize.

Feedback

Duration: 15 to 20 minutes

The purpose of this feedback session is to solidify students' learning experiences, allowing them to reflect on what they’ve learnt and share insights with classmates. This group discussion and 360° feedback not only reinforces the content but also hones their communication, collaboration, and constructive criticism skills, which are essential for both personal and academic growth.

Group Discussion

Group Discussion 🤝: Initiate a discussion with all students, allowing groups to share their learning experiences and conclusions. Suggested Outline:
