Purpose of Geometric hierarchy of numbers
Geometric hierarchy of numbers-To introduce the child to the hierarchies of the decimal system beyond one thousand and give a wider understanding of the function of the decimal system and to give an impression of the relationship between numbers, and the relationship of the hierarchies and the categories within the hierarchies. Subconsciously, other things come into the presentation, such as geometric progression: point leading to line, leading to surface or plane, leading to point.
