2. What is in a Montessori classroom? The Montessori classroom is a child-size world. Whatever is in the world outside can be incorporated meaningfully in the Montessori classroom. To a child, the world is overwhelming – it is big, complex, and confusing. By careful selection of materials by the teacher, an environment is set up that allows the child a place to explore life on a level he can understand. The materials or exercises are designed to stimulate independent exploration. This prepared environment entices the child to proceed at his own pace from simple activities to more complex ones. Through this process, the child’s natural curiosity is satisfied and he begins to experience the joy of discovering the world around him.
