How are the cultural areas taught at your school?
Look for specific information on the cultural subjects. Having a set time to teach the cultural subjects is fine (it is usually in the afternoon), but after the subject material is taught, practice and exploration of these topics should be integrated into the rest of the curriculum during the extended work period.
Dr. Montessori called science, history, social studies and geography the “cultural subjects” because she believed that the knowledge and understanding of these subjects is what makes the difference between a “literate” person and a “cultured” person. Today we might use the term "educated". The Montessori cultural studies is another thing that makes a Montessori classroom so different from other classrooms. The cultural subjects are taught in a very specific order, (big picture to smaller parts), and integrated into the curriculum. Eventually, after the foundation of each of the individual cultural areas is set, the study of the individual areas are then integrated into each other as well as the core curriculum, creating a deeper understanding of the world and the interconnectedness of everything in it.
