About Us!

Children's House

Children's House is a multi-age group of three and four-year-old preschoolers and five-year-old kindergartners. The environment is designed to bridge the gap between school and home. It is filled with beauty, purposeful Montessori materials that start with the most hands-on and concrete and move on to the more abstract, and promotes independence through social interactions with others.

Elementary One Classroom

E1 is a multi-age group of 1st, 2nd, and 3rd graders. In this room, you will find students working as a community exploring all that life entails. The materials for these students are beautifully designed pieces that attract the children's eyes and intrigue them to take off the shelf and manipulate. The Montessori curriculum spirals, pulling from prior learning and adding new experiences that build up to future lessons.

The Great River Montessori school (GRM) values diversity among our students and admits students of any race, color, national and ethnic origin to all the rights, privileges, programs, and activities generally accorded or made available to students at the school. It does not discriminate on the basis of race, color, national and ethnic origin in administration of its educational policies, admissions policies, scholarship and loan programs, and athletic and other school-administered programs.  Further, we will not discriminate on the basis of gender, sexual orientation, religion, economic status, mental or physical condition or disability in the administration of our educational policies, admissions policies, scholarship and loan programs, and athletic and other school-administered programs.
