mixed-age program overview

A five-weekday program provides 3 to 5 year-olds with a sense of order, continuity, and community. We offer a morning program with the option to add flexible extended day dismissal times to meet your family's needs. We also offer an afternoon-only program for families who prefer this scheduling option.

Mixed-age classrooms are at the heart of the Montessori philosophy. Being in an environment with children across a two-and-a-half-year age span allows each child to learn from and work with peers in a range of social, emotional, physical, and cognitive developmental stages. This arrangement mirrors the real world, in which individuals work and socialize with people of various ages, abilities, and dispositions.

Our classrooms are designed to support this style of learning within a low child-to-teacher ratio of 6:1. Younger children observe what slightly older children are doing, piquing their curiosity. Older children model how activities are done, reinforcing their self-esteem and sense of mastery. 

Work Time

Another hallmark of the mixed-age Montessori classroom is the uninterrupted work period, in which children have extended periods of time to select, focus on, and complete activities on their own. Consistently participating in this cycle allows children to develop coordination, concentration, independence, and order, while also instilling a sense of accomplishment and confidence. Teachers guide by inviting children to explore the materials.


On our 3,000 square foot terrace playground and playscape, the children enjoy each other's company and develop their physical abilities. An indoor gym space is available on days of inclement weather, so that the children's daily physical needs are always met. Our classrooms also include an array of materials and activities that support the development of both fine and gross motor skills.


The classroom environment is equipped with a multitude of Montessori materials, both traditional and teacher-made. The materials are designed to pique curiosity and are self-correcting, thereby heightening a child’s ability to independently learn and discover new ideas. The materials also help develop memory and refine the visual and auditory senses.


Grace, courtesy, and empathy are vital to the culture and curriculum of our school. Through reading books, circle time, and class discussions, teachers help children develop social consciousness in age-appropriate ways. Blocks and puppet areas allow children to collaborate and develop their imagination, while practical life activities facilitate socialization and role-play. As teachers and older children model courteous and peaceful behavior, younger children catch on and begin to do the same.


We offer daily Mandarin and Spanish immersion classes to children enrolled in the Morning Mixed-Age Program

Our Explorers Kindergarten Prep Program is available in the afternoons for children ages 4 and older. 


We encourage children to ask questions, to wonder, and to explore the world. To expand children's  creativity, a variety of activities, including art, music, dance, yoga, and cooking, are interwoven into the curriculum. Presentations of new materials, textures, smells, sounds, visual stimuli, and edibles enhance their vocabulary and senses.
