In other words, adults must never do for the child anything that the child can learn to perform for him or herself. Instead, the adult must protect each child's choice by ensuring that the child will be able to work with the chosen learning materials without interruption of interference from other children. Beauty is another principle of the prepared environment. Objects placed in the classroom are attractive and elegant, designed to attract the child's interest and attention. The classroom objects also represent reality and nature.
Children use real sinks and refrigerators instead of play ones.
Because in real life everyone does not have the same thing at the same time, there is only one piece of material instead of multiple sets. Contact with nature and reality are a third principle. Dr. Montessori taught that a child's direct contact with nature results with understanding and appreciating order, harmony, and beauty. The Montessori classroom environment is a place of life. Children learn to take care of plants, animals and fish.
