This manual deals with the Notion of time, Age of Earth, Fundamental Needs of People, Clock of Eras etc. and gives an introduction to the study of history.
Dr. Montessori states that the study of history begins by giving to the child a history
of the universe. This will not only strike the imagination of the child, but it will create
in the child wonder and amazement, sentiments which are higher than interest. The
knowledge that brings wisdom is complete only if we give first a vision of the whole.
This vision of the whole is an indirect preparation for the understanding of details. The
laws of the universe, even though they are presented to the child in a scientific way, can
be presented in an interesting way, with the help of materials and experiments. The
experiments will arouse the interest of the child and will be a moral lesson.
