140 stackable number building blocks in four colours, from one to ten in proportional height — maths becomes visible. The one is one centimetre, the ten is ten centimetres tall: size ratios become understandable with your hands.

How children play with these
On the light table, the child builds the number 7 on top of a 3 — the tower is exactly as tall as a 10. This makes addition visible. Later, differences are formed, quantities compared, towers arranged in the play of light. The translucent acrylic casts coloured shadows on the table, and maths becomes aesthetics.
