Do parents want their child's school to be an adventure? Well, a new preschool is banking on it, as the Adventure in Montessori Early Childhood Center opened in April in Jamaica Plain. Adventure in Montessori (AIM) is a Spanish bilingual school located on Rockwood Street, and offers care for infants through preschool. The Montessori Method of education was developed by Maria Montessori, and allows students to choose activities within a range of offered options. From that way students learn concepts from working instead of direct instruction.
