The Montessori environment is specifically and intentionally prepared for the child. Everything that is placed in the classroom has a purpose. When adding a material or an item to the classroom, it is important to ask, "How does this contribute to the child’s learning?"

Red and white striped popcorn buckets are used for everything from pencil holders to bookends on library shelves.
These classrooms are bright and colorful, but they are also cluttered and distracting.
