Elementary Program - 6 to 8 years - Main School The Elementary Program at Trail Ridge guides students from their Montessori foundation through an innovative educational experience that combines the full range of Lower Elementary Montessori materials with the best elements of the Ontario Primary curriculum. Our classroom encourages Elementary students to begin to think of the world outside our classroom windows and their special place in it. The Montessori philosophies of wonderment, responsibility, independence and a sense of community are at the cornerstone of our approach. Our teacher to student ratio in this room is 1:16.
