Every profession has its own jargon. "Montessori Primary Terminology," a companion publication to "Montessori for You and Your Child," defines vocabulary unique to an authentic Primary Montessori prepared environment. Names and summaries of official Primary presentations for two-and-a-half through six year old students are listed alphabetically as a valuable reference for parents. Primary lessons are also outlined and listed in their general order of presentation as an overview of the program to help inform families about the holistic education their children receive in the Casa under the guidance of a trained Montessori teacher.
