Activity Suggestions

Activity Recommendations

Activity 1 - 🏃‍♂️ LCM Marathon

> Duration: 60 - 70 minutes

- Goal: Apply the concept of LCM in a real-world scenario and utilize digital tools for simulation and presentation of findings.

- Deskripsi Activity: Students will be divided into groups to determine when two runners, going at different speeds, will cross paths again on the track. By using race simulation apps and online tools, they will find the least common multiple of the runners' speeds to identify the next meeting point.

- Instructions:

• Divide the students into groups of up to 5 members.

• Utilize a race simulation app (like Strava or a similar platform) and set two races with differing speeds.

• Each group needs to calculate the LCM of the runners' speeds to figure out when they will meet again.

• Students should check their results using online tools (like LCM calculators).

• After calculating, groups should put together a digital presentation (using Google Slides or PowerPoint) detailing their process and findings.

• Each group will share their conclusions with the class, discussing any challenges they faced and the strategies they employed.

Activity 2 - 🍕 LCM Pizza Party

> Duration: 60 - 70 minutes

- Goal: Use LCM to address a relatable issue and foster interaction and collaboration through digital tools and mock social media.

- Deskripsi Activity: Students will plan a 'pizza party' where various pizza flavors arrive at different times. They must calculate the LCM to ascertain when all flavors will be available simultaneously. The results will be discussed on a hypothetical social media platform created for the class.

- Instructions:

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

• Explain that each pizza flavor is delivered at different intervals (for example, margherita every 20 minutes, pepperoni every 30 minutes, etc.).

• Groups must calculate the LCM of the delivery times to find out when all flavors will be ready at once.

• Students should create posts and stories on a mock social media platform (using tools like Padlet or Google Classroom) to report their findings.

• Groups should engage with each other's posts, comparing results and discussing their different methods.

• Wrap up with a class discussion on how LCM facilitated problem-solving and the significance of teamwork.

Activity 3 - 🎮 Gamer LCM Challenge

> Duration: 60 - 70 minutes

- Goal: Make learning about LCM interactive and enjoyable through gamification, promoting collaborative problem-solving and the use of digital tools.

- Deskripsi Activity: Students will take part in an online game in teams where they must tackle problems involving LCM calculations to progress through levels. Each level will present a unique contextualized challenge, with students using digital platforms to solve them and document their solutions.

- Instructions:

• Divide the students into groups of up to 5 members.

• Select an educational gamification platform (like Kahoot! or Quizizz) to create a multi-level game, where each level features a problem involving LCM.

• Groups must resolve the problems at each level to move forward in the game.

• Encourage the use of online tools (like LCM calculators) as aids in problem-solving.

• Each group is responsible for documenting their solutions and reasoning on a collaborative platform (like Google Docs or Padlet).

• Conclude the game by having groups share their solutions and methods with the class, discussing the hurdles they faced and how they overcame them.

Feedback

Duration: 20 - 25 minutes

This stage is designed to allow students to reflect and share their thoughts, reinforcing the knowledge they've gained during the lesson. Through group discussions, reflection questions, and 360° feedback, students will have an opportunity to internalize their learning, identify strengths and areas for growth, and acknowledge the significance of teamwork and digital tools in the educational process.

Group Discussion

🗣️ Group Discussion: Run a group discussion with all students where each group shares what they learned from the activities and their outcomes. Use the following script to steer the discussion:

1. Ask students about the main challenges they faced during the LCM calculations in the activities.
2. Encourage each group to share the primary strategy they employed to address the problems.
3. Ask students to discuss how digital tools either aided or complicated the calculation process.
4. Invite students to explore how the LCM concept could be applied to other real-world scenarios, beyond those simulated in the activities.

Reflections

1. 🤔 What did you find most engaging about using apps and digital platforms to calculate LCM? 2. 📝 In what ways do you believe group collaboration assisted in tackling the problems posed? 3. 📈 Can you think of any other instances where you could apply the concept of LCM in real life?

Feedback 360º

🔄 360° Feedback: Guide students through a 360° feedback process where each peer must offer feedback to their group members from the activity. Help the class focus on providing constructive and respectful feedback with the following script:

1. Each student should highlight a positive contribution from each peer (e.g., 'You did a fabulous job at...').
2. Each student should suggest an area where each peer could improve (e.g., 'Perhaps you might consider enhancing...').
