By means of different heights, the numbers illustrate the relationship with other numbers: the 1 is one cm high, the 10 is ten cm high. The building blocks can be placed or stacked and built up into three-dimensional towers. In this way, children learn the basic arithmetic operations in a playful way and can take control of the result themselves. Contents: Numbers from 1-10 in 4 colours - 140 pieces
