CMS Elementary provides a powerful learning environment for young people. At this age, students build on the capacity for concrete learning developed in the Primary. They begin to think abstractly as their ability to reason increases. The question “What?” is supplemented by the questions “Why?” and “How?” as the students reach out to understand their world.

The school year begins with a dramatic series of lessons that demonstrate the physical structure and cosmic order of the universe. The students pursue their interests in the areas of geography, history, mathematics, geometry, biology and language. Exploration in these areas is encouraged through trips outside the classroom to community resources, such as the library, botanical garden, universities, the science center, etc.

Class work focuses on research and experimentation. The student’s imaginations are an effective tool, offering the opportunity for awe-inspiring inquiries into such areas as ancient history, chemistry, astronomy and paleontology.

Through the process of discovery, students develop their passion for learning as they grasp the idea that knowledge has no limits.

This strong academic focus is augmented by collaborative work, as well as physical education. Lessons in cultural subjects, such as visual, dramatic and musical arts, are an integral part of the elementary program. Students also receive instruction in a second language.

Graduates of CMS Elementary are well prepared socially and academically for the next step in their education. Our students consistently average within the top 10% of all students nationally on standardized tests. Our graduates have gone on to attend some of the most prestigious secondary schools in the St. Louis area.

  • Thank you for your interest in our school!

    Chesterfield Montessori School reopened our physical campus this past June and we are thrilled to have children back at school. We have been hard at work implementing our new safety guidelines and procedures during this unprecedented time. We are seeing first-hand how beneficial it is for our students to be in an environment that is designed to meet their unique developmental needs, along with their classmates, highly trained teachers and other loving adults.

    Since we are an intimate community, we have flexibility to meet the children’s needs in a way that just isn’t available to large schools and systems. Our five acre main campus offers large, sunny classrooms with excellent ventilation, extra indoor space and plenty of outdoor space. Additionally, we have a seven acre Land Lab in Wildwood that is available to our older students. We are committed to offering individualized education for every child, designed to support your child’s unique individual needs by implementing the authentic Association Montessori Internationale method at every level.

    While data is showing that we can educate our youngest children safely at school, we have created a strong Distance Learning option and hybrid schedule for older children as necessary, and will offer child care for essential workers, including extended care hours. (Parents and their employers determine who is an essential worker.) Our health and safety protocols have been designed in collaboration with infectious disease experts in our area, as well as the local Department of Public Health.

    Please call us at (314) 469-7150 or email admissions@chesterfieldmontessori.org to find out more. We look forward to hearing from you and learning more about your family!
