Maria Montessori described it “psycho-geometry” and defined it so the “measurement of the earth together with the consciousness of the reciprocal relationship between Man and the objects of the environment, and between the objects themselves.”
Maria Montessori extends this definition beyond the etymology (geometry: Greek ge the earth, Mother Earth from mythology, and metron measure, measurement of a dimension that is so vital to our lives.) Her definition especially this consciousness of geometry is so practical and so attached to reality for we are all a part of this.
Many refer to geometry as abstract, thus giving it to the child at a much later age and with the attitude that it is far removed from us and from reality.
Geometry, as it will be dealt with here, are the fundamental concepts of Euclidean geometry.
