Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - 🚀 Space Mission: Exploring an Interstellar Cylinder

> Duration: 60 - 70 minutes

- Objective: Apply metric relationships in cylinders to solve practical problems and develop skills in collaboration, use of digital technologies, and multimedia presentation.

- Description: Students will become astronauts on a space mission to explore and map an interstellar cylinder. Using an online 3D simulation of a cylinder, they will calculate distances and create a detailed report in a multimedia format, which may include videos and images captured during the exploration.

- Instructions:

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

• Each group should access a digital platform that allows for the creation and manipulation of 3D models, such as Tinkercad or SketchUp.

• Provide a basic model of a cylinder or ask the students to create a 3D cylinder.

• Students should identify and mark specific points on the two bases of the cylinder. These points will represent different locations of interest in their space exploration.

• The groups must calculate the distances between the points on the two opposite bases of the cylinder using metric relationships and document those calculations.

• Using video editing software, such as iMovie or Adobe Spark, students must create a mission report, incorporating calculations, 3D images, and any notes or videos captured during the exploration.

• At the end of the activity, each group should present their mission report to the class, highlighting the challenges and learnings.

Activity 2 - 📱 Digital Influencers: Cylindrical Product Campaign

> Duration: 60 - 70 minutes

- Objective: Develop the ability to apply mathematical concepts in real-world scenarios, use digital tools to create multimedia content, and simulate the dynamics of digital marketing campaigns.

- Description: Students will transform into digital influencers responsible for a promotional campaign of a new cylindrical product (e.g., a beverage can). They will use simulated social media and digital editing tools to calculate cylinder metrics and create engaging content that explains these measurements to the audience.

- Instructions:

• Form groups of up to 5 students.

• Each group should choose or be assigned a cylindrical product (e.g., soda can, potato chip tube, etc.).

• The groups will use their cell phones to measure the dimensions of the products and calculate the metric relationships, such as volume and surface area.

• Then, each group must create a digital influencer profile on a simulated social media platform (using Google Slides or Padlet, for example).

• Students should produce multimedia content (photos, videos, infographics) explaining the metric characteristics of the product and its importance.

• The groups must publish this content on the social media profile and interact with other 'influencers' (other groups) by commenting and discussing the posts.

• Each group will present their final campaign to the class, highlighting how they used the metrics of the cylinder to promote the product.

Activity 3 - 🎮 Gamification: Cylindrical Towers Challenge

> Duration: 60 - 70 minutes

- Objective: Engage students through gamification, promoting the practical application of mathematical concepts in a playful and collaborative environment.

- Description: Students will participate in a gamified challenge where they must build cylindrical towers of different sizes and solve mathematical puzzles involving metric relationships to advance in the game. They will use a digital gamification platform to complete the mission.

- Instructions:

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

• Each group must access a gamification platform, such as Kahoot! or Classcraft, where a game has already been set up by the teacher.

• The groups start by constructing virtual cylindrical towers of different heights and diameters, using tools such as Minecraft Education Edition or CoSpaces Edu.

• At every level of the game, the groups receive mathematical puzzles that involve calculating distances between points on the bases of the cylindrical towers.

• Groups must solve each puzzle correctly to advance to the next level and earn points.

• The group that reaches the final level and solves all puzzles in the shortest time wins the challenge.

• At the end of the activity, a class discussion will take place to reflect on the solutions found and the strategies used during the game.

Feedback
