Grimm's 100 piece stepped counting blocks set has a length of 44.5 cm. The 4 x 4 cm building block family consists of many different small building set all of the same 4 cm thickness. They compliment each other perfectly and can be combined in many different ways.
These 4 x 4 make ideal room decor as they invite everyone to play. Frames in the same size can also safely be stacked on top of each other. Since the blocks are not varnished, they do not fall apart easily.
These are also excellent mathematics aids : the blocks are from 1cm to 10cm high and so the numerical relationships to each other can be visualized.
