In the program’s own words

“SMS’s unique hybrid program—” Montessori+ “—offers a half-day Montessori curriculum as well as a half-day of extended, multi-disciplinary explorations that offer children the time they need to learn STEAM (Science, Technology, Engineering, Art, Music & Movement) concepts broadly and deeply.” sammamishmontessori.com, July 2026
“Rooted in Montessori Philosophy Dr. Maria Montessori believed in the power of the child’s innate talent and curiosity and stressed the importance of letting them follow their interests. Sammamish Montessori’s curriculum is centered around the core principles set out by Dr. Montessori.” sammamishmontessori.com, July 2026
