Montessori classroom is equipped with rich teaching AIDS according to the needs of children's growth. These teaching AIDS and materials are divided into five categories by region. The environment creation in the five fields is generally placed clockwise in the classroom according to the five fields of daily life, senses, mathematics, Chinese, science and culture. The display of teaching AIDS should be structured and orderly, following the principle of "from top to bottom, from left to right, from simple to complex, from concrete to abstract, from classic teaching AIDS to extended teaching AIDS". The placement of teaching AIDS has a sense of order, and the order of children is also reflected in a subtle way.

Montessori's "prepared environment" is a real environment suitable for children's needs. Children will act according to their own internal needs, development speed and rhythm, and in this process show the quality of loving order, concentrating for a long time, and trying to perform certain operations repeatedly without feeling tired. The creation of Montessori education room environment provides a scientific environmental foundation for children's healthy growth.
