The child, coming into the Casa, is interested in language, in facts, in sensorial exploration and profoundly so in his universe. With the geography materials, the child is given the facts of his physical world – that it is a sphere, that this sphere is composed of land masses and bodies of water, that these have different forms and that these forms have names.

Then more facts - that the land masses are called continents, and that the bodies of water are called oceans. And again - that the oceans and continents have names. The child at this age is also in a sensitive period for order, and the geography materials provide him with the opportunity for exploring the many levels of order established through the ages as we perceived and classified our earth, organizing it into countries, provinces, states, each with their own particular shapes, their intriguing names, their capitals and their flags. When the child arrives at the next plane of development, the time of intellectual exploration, the time of asking the why, when, wherefore of all things, the facts absorbed through this sensorial exploration provide a solid foundation for him to rediscover that which he already knows. And now he is able to integrate the physical characteristics of the land and water, to understand human affairs past and present that evolved upon them, and to become aware of man’s dependency on, as well as responsibility for, the habitat he shares with a myriad of other forms of life.
