Where can a student practice swimming, complete the Hundred Board and build a fort all in the same day? Lexington Montessori School is proud to serve as an affiliate of HORIZONS National, a 27-year-old organization striving to build brighter futures for all children.

The HORIZONS program model effectively combines high-quality academics with cultural enrichment and confidence-building opportunities. HORIZONS is designed to have children maintain and make progress academically during the six-week summer program, ready to start the new school year in the fall, for consecutive summers through middle school. 

The program offers a Montessori Work Cycle, pool time at the Waltham YMCA three times a week, as well as enrichment classes in art, farming, music and physical education.

Activities during Horizons@LMS

Horizons@LMS immerses children in a Montessori-informed, hands-on, multi-age learning experience that fosters independence and instills a sense of agency in every learner. Each summer children return to discover the joy of learning and the power of their potential as they embody the change we all wish to see in the world.
