• At the end, groups should watch each other's videos and provide positive feedback, highlighting what they learned and appreciated in each video.

Activity 2 - Virtual Treasure Hunt of Prime Numbers 🔍💻

> Duration: 60 - 70 minutes

- Objective: Encourage teamwork, logical reasoning, and practical application of the concepts of prime and composite numbers, as well as make learning interactive and dynamic.

- Description: Students will participate in a virtual treasure hunt where they will solve puzzles and challenges involving the identification of prime and composite numbers and the decomposition of numbers into prime factors. Each clue will be a web page or a shared document leading to the next challenge.

- Instructions:

• Divide students into groups of no more than 5 people.

• Explain that they will participate in a virtual treasure hunt, where each group must solve mathematical puzzles and challenges to find the next clue.

• Provide the first clue, which contains a link to a web page or shared document. This link leads to a puzzle that, when solved, will provide the next clue.

• Puzzles and challenges may include finding prime numbers in a sequence, decomposing numbers into prime factors, solving simple cryptography problems using prime numbers, etc.

• Use tools like Google Docs, Google Forms, or even quiz-making sites to create the challenges and clues.

• Each group must continue solving puzzles until they find the 'treasure,' which can be a congratulatory message or a virtual completion certificate.
