Following the voting process, it was selected as the “Project of the Month – April”
It was created at the very beginning of the project as a dedicated space for teachers, where they collaborate to design engaging educational resources.
One hundred years later, teachers took on the mission of Professor Numeronius, because the educational resources created for students turn every lesson into an adventure and every problem into a mystery to solve. The teachers’ task was clear:
“Create engaging mathematical resources (puzzles, games, challenges) that can be integrated into missions, helping students discover and unlock the secrets of the Treasure of Logical Thinking.”
To make the project easy to integrate into the curricula of the three countries and to ensure participation of all students aged 6 to 12, the teachers established a flexible structure adapted to different learning levels.
🔑 Mission 1: Discover the beginning of the adventure! ✨
🔑 Mission 2: The Magic Operations – Addition and Subtraction! ✨
🔑 Mission 3: The Magic Operations – Multiplication and Division! ✨
🔑 Mission 4: Detective in the World of Shapes – Geometric Figures! (Tangram) ✨
🔑 Mission 5: The Treasure of Problems and Logical Thinking ✨
📌 Activity results: 📌
Following the implementation of the 5 missions, a total of 80 educational resources and 12 learning routes were created, meaning 92 educational resources developed across:
This final mission represents the ultimate challenge, where students use all the skills they have developed to solve complex problems and engage in logical thinking tasks. It is the culminating moment of discovering the “treasure,” where reasoning, strategy, and perseverance are essential for success.Students work in teams, divided into 12 groups, each following its own final challenge path organized into 5 levels. Each level includes 3 tasks in the form of exercises and problems. At the end of each path, the teams discover a letter, which they manually create from recycled materials (newspapers). These letters are then integrated into the final word of the mission.
🔎 The final challenge question is:
🏆If all the groups have discovered the letters and created them from pieces of newspaper, use the Interactive Hangman to discover the Treasure of Logical Thinking!
We are happy to announce the participation of the eTwinning project The Mystery of the Mathematical Treasure in the STEM Discovery Campaign 2026! 🌍➕Through interactive activities, mathematical challenges, educational games, and international collaboration, students discovered that mathematics can become a true adventure of learning. 🧩🔢✨
The project encouraged:
Congratulations to all the students, teachers, and partners involved for their enthusiasm, creativity, and teamwork! 💙
Dear partners,
On the occasion of eTwinning Day, I would like to express my sincere gratitude and appreciation for your involvement in our mathematics project. This special day of eTwinning gives us the opportunity to reflect on what we have built together: an educational space based on collaboration, creativity, and active learning, where mathematics has become a bridge between cultures, ideas, and experiences. Thanks to you, our project is not just an educational initiative, but an authentic European learning experience.
I wish you an inspiring eTwinning Day full of joy and new ideas for collaboration!
On the occasion of eTwinning Day 2026, our students embark on a mathematical adventure full of discoveries to reveal the secret message: “eTwinning Day 2026”! ✨
Working in 2 international groups, children explore the fascinating world of mathematics by decorating letters using geometric shapes, creative patterns, and symbolic colors, collaborating with partners from different countries to build together the “mathematical treasure.” 🌍🤝
🎨 The final results will include:
🔢 two fully decorated messages
📐 the representation of geometric shapes and mathematical concepts
💡 the integration of the project theme “The Mystery of the Mathematical Treasure”
🖼️ collective posters published on TwinBoard
🎥 a short video showcasing the teamwork process and final creations
Through this activity, students develop logical thinking, creativity, and international collaboration skills, turning mathematics into a fun, artistic, and memorable experience! ✨
