Primary Program and Extended Day Programs are for children 2 1/2 through Kindergarten

“The most important period of life………..is the first one, the period from birth to age six,” said Dr. Montessori “For that is the time when man’s intelligence itself, his greatest implement, is being formed.”

The programs at the Montessori School St. Clair are offered to children between the ages of 2 1/2 through Kindergarten. These programs prepare children for life.  At this age, children actively learn at a tremendous rate, a stage Dr. Maria Montessori called “the period of absorbent mind”. Our programs emphasizes independence and self-sufficiency, where children learn “practical life” skills such as cleaning, food preparation and caring for others.

Our programs are designed to help children thrive academically, socially, and psychologically. Our students follow a rigorous Montessori curriculum that sets expectations far higher than the standard, state-approved curriculum. The learning program is personalized and catered to individual learning styles. Children work at their own pace ensuring that they meet these expectations. In the Primary and Extended day programs, children take an active role in maintaining their environment, which is divided into four main areas: practical life, sensorial, language and mathematics.

Children begin to read and write through a variety of activities. They learn about their world by studying the continents, animals, plants, and other cultures. They work with concrete materials to learn mathematical concepts including the decimal system, geometry and fractions.
