Montessori 6-12

“Education between the ages of six to twelve is not a direct continuation of that which has gone before, though it is built upon that basis.  Psychologically there is a decided change in personality, and we recognize that nature has made this a period for the acquisition of culture, just as the former was for the absorption of the environment.”
Maria Montessori | To Educate the Human Potential, p. 3
“The secret of success is found to lie in the right use of imagination in awakening interest, and the stimulation of seeds of interest already sown by attractive literary and pictorial material, but all correlated to a central idea, of greatly ennobling inspiration – the Cosmic Plan in which all, consciously or unconsciously, serve the Great Purpose of Life.”
Maria Montessori | To Educate the Human Potential, p. 3
“…the Cosmic Plan can be presented to the child, as a thrilling tale of the earth we live in….”
Maria Montessori | To Educate the Human Potential, p. 2
“Illustrated as it must be by fascinating charts and diagrams, the creation of earth as we now know it unfolds before the child’s imagination….”
Maria Montessori | To Educate the Human Potential, p. 2
“We are confronted with a considerable development of consciousness that has already taken place, but now that consciousness is thrown outwards with a special direction, intelligence being extroverted, and there is an unusual demand on the part of the child to know the reasons for things.”
Maria Montessori | To Educate the Human Potential, p. 3
“Knowledge can be best given where there is eagerness to learn, so this is the period when the seed of everything can be sown, the child’s mind being like a fertile field, ready to receive what will germinate into culture.  But if neglected during this period, or frustrated in its vital needs, the mind of the child becomes artificially dulled, henceforth to resist imparted knowledge.  Interest will no longer be there if the seed be sown too late, but at six years of age all items of culture are received enthusiastically, and later these seeds will expand and grow.”
Maria Montessori | To Educate the Human Potential, p. 3
“…to give the whole of modern culture has become an impossibility and so a need arises for a special method, whereby all factors of culture may be introduced to the six-year-old; not in a syllabus to be imposed on him, or with exactitude of detail, but in the broadcasting of the maximum number of seeds of interest.  These will be held lightly in the mind, but will be capable of later germination, as the will becomes more directive, and thus he may become an individual suited to these expansive times.”
Maria Montessori | To Educate the Human Potential, p. 3/4
“A second side of education at this age concerns the child’s exploration of the moral field, discrimination between good and evil.  He no longer is receptive, absorbing impressions with ease, but wants to understand for himself, not content with accepting mere facts.  As moral activity develops he wants to use his own judgment, which often will be quite different from that of his teachers.”
Maria Montessori | To Educate the Human Potential, p. 4
“An inner change has taken place, but nature is quite logical in arousing now in the child not only a hunger for knowledge and understanding, but a claim to mental independence, a desire to distinguish good from evil by his own powers, and to resent limitation by arbitrary authority.  In the field of morality, the child now stands in need of his own inner light.”
Maria Montessori | To Educate the Human Potential, p. 4
“Yet a third interesting fact to be observed in the child of six is his need to associate himself with others, not merely for the sake of company, but in some sort of organized activity.  He likes to mix with others in a group wherein each has a different status.  A leader is chosen, and is obeyed, and a strong group is formed.  This is a natural tendency, through which mankind becomes organized. ”
Maria Montessori | To Educate the Human Potential, p. 4
“If during this period of social interest and mental acuteness all possibilities of culture are offered to the child, to widen his outlook and ideas of the world, this organization will be formed and will develop; the amount of light a child has acquired in the moral field, and the lofty ideals he has formed, will be used for purposes of social organization at a later stage.”
Maria Montessori | To Educate the Human Potential, p. 4
“… we have learnt from him certain fundamental principles of psychology.  One is that the child must learn by his own individual activity, being given a mental freedom to take what he needs, and not to be questioned in his choice.  Our teaching must only answer the mental needs of the child, never dictate them.  Just as a small child cannot be still because he is in need of co-ordinating his movements, so the older child, who may seem troublesome in his curiosity over the why, what and wherefore of everything he sees, is building up his mind by this mental activity, and must be given a wide field of culture on which to feed.”
Maria Montessori | To Educate the Human Potential, p. 4/5
“The task of teaching becomes easy, since we do not need to choose what we shall teach, but should place all before him for the satisfaction of his mental appetite.  He must have absolute freedom of choice, and then he requires nothing but repeated experiences which will become increasingly marked by interest and serious attention, during his acquisition of some desired knowledge.”
Maria Montessori | To Educate the Human Potential, p. 5
“Since it has been seen to be necessary to give so much to the child, let us give him a vision of the whole universe.  The universe is an imposing reality, and an answer to all questions.”
Maria Montessori | To Educate the Human Potential, p. 5
“We shall walk together on this path of life, for all things are a part of the universe, and are connected with each other to form one whole unity.  This idea helps the mind of the child to become fixed, to stop wandering in an aimless quest for knowledge.  He is satisfied, having found the universal centre of himself with all things.”
Maria Montessori | To Educate the Human Potential, p. 6
“If the idea of the universe be presented to the child in the right way, it will do more for him than just arouse his interest, for it will create in him admiration and wonder, a feeling loftier than any interest and more satisfying.  The child’s mind will then no longer wander, but becomes fixed and can work.  The knowledge he acquires is organized and systematic; his intelligence becomes whole and complete because of the vision of the whole that has been presented to him, and his interest spreads to all, for all are linked and have their place in the universe on which his mind is centred.”
Maria Montessori | To Educate the Human Potential, p. 6
“No matter what we touch, an atom, or a cell, we cannot explain it without knowledge of the wide universe.  What better answer can be given to those seekers for knowledge?  It becomes doubtful whether even the universe will suffice.  How did it come into being?  How will it end?  A greater curiosity arises, which can never be satiated; so will last through a lifetime.  The laws governing the universe can be made interesting and wonderful to the child, more interesting even than things in themselves, and he begins to ask:  What am I?  What is the task of man in this wonderful universe?  Do we merely live here for ourselves, or is there something more for us to do?  Why do we struggle and fight?  What is good and evil?  Where will it all end?”
Maria Montessori | To Educate the Human Potential, p. 6
“Not only can imagination travel through infinite space, but also through infinite time; we can go backwards through the epochs, and have the vision of the earth as it was, with the creatures that inhabited it.”
Maria Montessori | To Educate the Human Potential, p. 10
“To make it clear whether or not a child has understood, we should see whether he can form a vision of it within the mind, whether he has gone beyond the level of mere understanding.”
Maria Montessori | To Educate the Human Potential, p. 10
“The secret of good teaching is to regard the child’s intelligence as a fertile field in which seeds may be sown, to grow under the heat of flaming imagination.  Our aim therefore is not merely to make the child understand, and still less to force him to memorize, but so to touch his imagination as to enthuse him to his inmost core.”
Maria Montessori | To Educate the Human Potential, p. 11
“…the child begins to become conscious of right and wrong, this not only as regards his own actions, but also the actions of others…..moral consciousness is being formed and this leads later to the social sense." 
Maria MontessoriThe Absorbent Mind, p. 177
“Our experience with children in elementary schools has shown us that the age between six and twelve years is a period of life during which the elements of all sciences should be given. It is a period that, psychologically, is especially sensitive and might be called the "sensitive period of culture" during which the abstract plane of the human mind is organized.”
Maria Montessori | From Childhood to Adolescence, p. 85
