In the project “Colorful Mathematics with KORBO,” mathematical activities are carried out in groups. Children solve tasks together, compare results, build structures, and jointly draw conclusions. This is teamwork in which cooperation, the exchange of ideas, and the creation of shared projects are essential. Mathematics is experienced here through hands-on activities: building, organizing, and analyzing.

That is why having an appropriate number of elements is crucial. Different sets may work better for groups of different sizes. It is worth remembering that a large number of gears, cylinders, and platforms allows a group to truly experience mathematical concepts in practice.

We do not define one universal number of blocks per child, because mathematics in motion is not about individual tasks but about teamwork. In practice, however, we know that:

• KORBO STEAM – the most comprehensive choice. It contains 2,450 blocks, including 4 coordinate system sets adapted to Korbo platforms, 100 tire pieces for wheels that enrich many activities, a set of large gears, 25 individual work bags, as well as 600 wheels in 6 colors and 600 cylinders in 6 colors for vertical building. This quantity is more than sufficient for a class of 25 students. Ideal for project-based work in schools and kindergartens.
• KORBO MALUCH – contains 1,450 blocks and works well in smaller groups and in kindergartens. It includes 300 wheels in 6 colors and 400 cylinders in 4 colors, special clips for attaching figures and labels to blocks, and a coordinate system for younger children (from 1 to 6).
• KORBO SPE – 915 elements, allowing selected activities to be carried out. It includes 350 wheels in 6 colors and 230 cylinders (in varying color proportions, which may slightly complicate dividing the elements). Sufficient for smaller groups. Does not include additional accessories.
• KORBO CONCEPT 450 – a set for working with a small group of children. We recommend purchasing missing elements, such as orange and green wheels, to ensure consistency with other sets. It contains a limited number of cylinders for vertical building.

The choice of a set should be matched to the size of the group and the planned working style. Each of them can support a fascination with mathematics—as long as we give children space for cooperation, building, and independent discovery of relationships.
