"Montessori 1" generally refers to the first level of the Montessori education system, which is the nursery or preschool level, typically for children aged approximately 2.5 to 3.5 years. This program focuses on developing foundational skills through hands-on activities like practical life exercises, sensorial activities, and introductory language and math concepts. The goal is to foster independence, refine motor skills, and build a strong foundation for future learning.
