Curiosity, research and group work through cosmic education

Program Overview

The Montessori elementary program builds on the primary years with a connected curriculum in which history, science, language and math are taught as parts of one story.

Good to Know. Some schools divide it into Lower Elementary (6 to 9 years) and Upper Elementary (9 to 12 years), while others keep children together from 6 to 12. AMI standards allow either grouping.
