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.
