Haba Educational STEM System Construction Site, 2+ years , 4010168229065

Kullerbü – Construction Site is a dynamic educational system in which the child actively participates in the game through movement, carrying and action. Here the balls do not just move – they are loaded, pushed and transported.

The set includes a dump truck and a wheel loader, which create a real game situation. The loader pushes the balls to the construction site, and the dump truck transports them back. This makes the game much more engaging and understandable.

The system uses solid wooden balls Ø 4.6 cm, which are stable, easy to grip and safe for young children. The movement is clearly traceable and repeatable.

The elements are connected stably through the smart click system, and the construction allows for different game and upgrade options.

This set is particularly valuable because it combines movement, action and result – the child sees what he is doing and understands why it is happening.

Suitable for individual work, kindergarten and work with educators, speech therapists and resource teachers. Suitable for children with SEN, as it supports tracking, repetition, independence and understanding through action. The system also follows the Montessori principle – learning through action and own pace.

How to play
The child places the balls, pushes them with the loader to the construction area and then transports them with the dump truck. The process can be repeated many times, creating different game situations.
