Montessori Quote
The aim of this apparatus is the same: to aid visual discrimination of size or dimensions. The sets of apparatus are coloured differently and attractively, but the differences between them are the salient part. Long Rods – differ in one dimension. Broad Stair – differs in two dimensions. Pink Tower – differs in three dimensions.
