Answer:
Montessori preschools, developed in Italy, employ a carefully designed set of materials to create an environment that fosters sensory, motor, and language development through play.
Step-by-step explanation:
It was Italian educator Maria Montessori who developed the method that now bears her name. Montessori preschools offer children a motivational environment for learning and developing emotionally, physically, socially, and cognitively. Montessori schools have mixed-aged classrooms where children get to choose activities and materials among the options provided. The method is a constructivist one, in which children learn by doing instead of by being directly instructed.
