As part of European Code Week, preschoolers took part in the activity „The Little Fish in the Pond Play Hide and Seek," using the Bee-Bot educational robot. On a themed mat representing a pond, each child chose a fish and programmed the robot to guide it safely to its hiding spot, avoiding the storks along the way.

The activity unfolded in four stages an introduction to the materials and the task at hand, a demonstration of the Bee-Bot's basic commands, individual programming of each child's chosen path, and a closing reflection, in which the children explained the strategies they had chosen and the solutions they had found.

Through this activity, the children were introduced to basic concepts of programming and robotics, while practicing algorithmic thinking, spatial orientation, and the ability to work through a problem to find a solution.

Afterward, the children swapped worksheets with one another and worked through their classmates' paths, strengthening their analytical skills, spatial orientation, and algorithmic thinking. Once they had finished, they went on to color a themed picture according to a color code.

The Code Week activities were fully integrated into the project theme, "Our World – Lakes Through Children's Eyes." Using ScratchJr, students created and programmed animations of a lake environment. They animated characters, designed stories about lake plants and animals, and learned to build simple algorithms through coding. In Minecraft Education, students designed and constructed a lake ecosystem by creating shorelines, aquatic vegetation, animal habitats, and other elements of the natural environment, while developing their creativity, spatial thinking, and digital design skills.

Equally important were the unplugged coding activities. Through hands-on programming tasks without computers, students developed their algorithmic thinking and problem-solving skills. They learned what pixels are, discovered how digital images are created from tiny coloured squares, and completed pixel-art colouring activities based on a lake theme by following coded instructions.

These activities helped students understand that coding can be meaningfully connected with environmental education, creativity, and problem-solving. Participation in Code Week 2025 strengthened students' digital competence, computational and algorithmic thinking, creativity, and collaboration skills. At the same time, the shared eTwinning project code and common project theme reinforced the sense of international cooperation and encouraged students to feel part of a wider European learning community.
