Morning & Full-Day Mixed-Age Program


basic Program: 9:00 a.m. - 12:30 p.m. | $21,774

Two classrooms featuring natural light and high ceilings are dedicated to our morning mixed-age program. After dropoff, children come together in morning circle, followed by periods of work time and play on the rooftop terrace. On some days, special activities such as music, cooking, and yoga are integrated into the classroom. 


ADd on options:


LUNCH With Friends: 9:00 a.m. - 1:30 p.m. | $23,523

After class ends at 12:30 p.m., some children remain until 1:30 p.m. to enjoy lunch with friends and teachers in the classroom. This also includes rest and relaxation after their meals and story time with their teachers. (Lunch is provided by families). 


Extended day: 

Extended day is designed to be a seamless experience in the daily life of a preschool age child. It should not be thought of as "school." After lunch ends at 1:30, older children transition to afternoon activities while younger children can nap for 60-90 minutes. 

The children in our extended day programs come together with children in our afternoon mixed-age program. They enjoy activities on the terrace playground, nature walks on the Upper West Side, art, dance, cooking, yoga, and more. Montessori enrichment time is also available for children who wish to continue exploring the materials and activities from their morning classes. 

We offer three extended day dismissal options: 

9:00 a.m. - 3:30 p.m. | $27,021

9:00 a.m. - 5:00 p.m. | $29,645

9:00 a.m. - 6:00 p.m. | $31,395

Families who may only occasionally need to utilize our extended day dismissal options are welcome to do so for $13 per each additional hour beyond the child's regular schedule. 


Spanish OR MANDARIN: MONDAY - FRIDAY | 8:30 A.M. - 9:00 A.M. | $2,600 (added to BAse Tuition)

We believe it's important to offer children the opportunity to acquire new languages. Children under 6 possess a natural proclivity for language acquisition, and our ever-shrinking global society encourages future generations to develop foreign language skills.

We offer the option to enroll your child in either Spanish or Mandarin classes. Children are taught the basics via hands-on methods and learn about the peoples and cultures that speak these languages.


Explorers kindergarten prep program: 9:00 A.m. - 3:30 p.m. | $30,015 

The Explorer’s program offered a perfect introduction to Kindergarten concepts, while also staying true to the intimate setting and hands-on learning experience of a Montessori program. We loved how each day of the week focused on a different subject, from math and science to art and world cultures. The projects in each of these subjects were very engaging for our child, who has gained an impressive knowledge of early math and literacy concepts, discovered a passion for the solar system, and created beautiful artworks inspired by famous artists such as Frida Kahlo and Jackson Pollock.

Our Explorers Program began over 30 years ago to meet the developmental needs of kindergarten-bound children. The program has received accolades from families as well as ongoing schools to which our alumni children have exmitted, including public, gifted & talented, private, and parochial schools.

Children enrolled in our morning mixed-age program who are 4 years-old or older are eligible for the Explorers Program. 

To prepare preschool children to transition from a Montessori environment to a kindergarten setting, this program introduces children to kindergarten-level materials, concepts, and routines. Lessons are presented by the teacher, followed by group and individual practice.  

Afternoon snack is provided by MMS.
