The 1st grade students from the Vocational School in Petricani, Romaniaactively participated in an engaging Tangram activity. They showed great enthusiasm and involvementwhile solving the tasks, demonstrating creativity and a strong willingness to find solutions.
The activity was dynamic and interactive, with students eager to take part and express their ideas. Through play, they developed logical thinking, collaboration skills, and imagination.
We also worked in international teams and were part of Group 5, where collaboration played an essential role in successfully completing the tasks. A lively and meaningful learning experience!

MİSSİON 4: DETECTİVE İN THE WORLD OF SHAPES -GEOMETRİC FİGURES! - TANGRAM
My students used their imagination and creativity to reconstruct geometric shapes through collaboration and teamwork. They created innovative tangram models. They learned while having fun.
"Our Tangram activity with our 2nd grade students transformed mathematics from formulas on paper into a tangible and fun experience. Using seven basic geometric pieces, our students not only created original designs but also significantly improved their ability to recognize geometric shapes, understand part-whole relationships, and reason spatially.
During this process, the little hands, working patiently and attentively, strengthened their basic mathematical reasoning and problem-solving skills in the stages of rotating and joining the shapes. By working with concrete materials and internalizing abstract mathematical concepts, our students enjoyed learning by doing and experiencing, while also discovering the aesthetic and creative aspects of geometry."

Mission 4 completed!
I was part of group 5. Students from grade 4 B from Secondary School No. 1 Orbeni completed mission 4, wanting to complete all 5 logical challenges, not just two, with the goal of reconstructing exact geometric models using all 7 pieces of the Tangram set. This stage tested their patience and spatial vision. Later, moving from rigor to creativity, the students freed the pieces from the imposed shapes and reorganized them to model the silhouette of a bird. The result demonstrated that the same rigid pieces can come to life through imagination.
Mission No. 4 ended with a touch of regret from the children. They worked with great enthusiasm and enjoyment. They were not satisfied with creating just 5–6 Tangram shapes; they wanted to complete them all and then create new ones of their own. Through this activity, they developed their team spirit, logical thinking, digital skills, and imagination.

In Mission – Detective in the World of Shapes, the students of Preparatory Class D from “Simion Stolnicu” High School in Comarnic explored the world of geometric shapes through interactive and collaborative activities. Using Tangram puzzles, the children worked in pairs to complete the tasks and proposed their own original creative Tangram to their international partners.
The students reconstructed geometric models such as the cat, swan, dove, fish, and camel, respecting the shape and orientation of the pieces. The activity continued with the creation of a creative Tangram, in which each team used imagination and spatial thinking to build original shapes, challenging their international partners to reproduce them.
During the activity, one of the main difficulties encountered was correctly fitting the pieces within the given Tangram space. However, after completing the first exercise, the students better understood how to position the pieces and were able to organize their constructions more efficiently in order to fit the required space.
The entire process was filmed, capturing the students’ engagement, collaboration, and the way they thought and solved problems together.

Mission 4 completed! I was part of Group 7. The students from Class 3B at Secondary School No. 1 Orbeni successfully completed Mission 4. They tackled the challenge of reconstructing exact geometric models using all 7 pieces of the Tangram set. This stage tested their patience and spatial awareness. Thank you!

Mission 4 was successfully completed! We were part of Group 3. The students were excited to solve all the Tangram puzzles, They carefully reconstructed the models, creating the swan, the camel, the cat and the fish. This activity helped us to recognize geometric figures, develop our creativity, motor skills and logical-spatial thinking, through play.

The students of Class I B from School No. 156 Bucharest have successfully completed Mission 4. On group 5 students was determined to go above and beyond, tackling all 5 logical challenges of the Tangram set rather than just the minimum requirements. By focusing on the exact reconstruction of geometric models using all 7 pieces, we put our patience and spatial awareness to the test.
Once we mastered the rigor of the geometric tasks, we shifted our focus to pure creativity. We moved beyond the imposed shapes, freely reorganizing the pieces to model the silhouette of a cat. The final result beautifully demonstrated that even the most rigid geometric shapes can come to life through the power of a child's imagination.

My students, enjoyed completing Mission 4. They transformed the Tangram exercises from a simple geometric activity into a problem-solving experience. The inherent trial-and-error method significantly contributed to the development of their patience and perseverance. Every mistake made in positioning the pieces was turned into an opportunity for logical deduction; achieving the target figures reinforced their self-efficacy and confidence in their cognitive abilities.

The use of tangram by the 4th grade students highlighted both their creativity and their ability to solve problems in an intuitive way. The children were actively involved in the activity, showing curiosity and a desire to explore. By manipulating the pieces, they were able to better understand geometric concepts such as shape, symmetry and spatial relationships.
The tangram also stimulated logical thinking and perseverance, as the students were challenged to find different solutions to build various figures. The activity encouraged collaboration between colleagues, the exchange of ideas and learning through discovery.
Thus, the tangram proved to be an effective teaching tool, combining play with learning and contributing to the harmonious development of the mathematical and creative skills of the students.

During Mission 4, my students from 5-th grade explored geometric shapes through a
series of Tangram challenges that combined logic, creativity, and teamwork.
Working in international groups motivated them to communicate, share ideas, and take responsibility for their part of the mission.
By reconstructing the required Tangram models and designing their own creative shape, students strengthened their spatial reasoning, problem‑solving skills, and imagination.
The digital resources helped guide their work, while the editable worksheets ensured
that every student could participate.Overall, this mission offered a fun and meaningful
way for students to understand geometric figures and collaborate with peers from
different countries. Their enthusiasm and engagement showed how much they
enjoyed acting as “little math detectives” on their journey toward the mathematical
treasure.
