The Montessori classroom is prepared by the teacher to encourage independence, freedom within limits, and a sense of order. Every day children practice concentrating on work they choose and are given time to accomplish the work in their own time, not just until the bell rings for the next class. They can be so absorbed in the task at hand that long periods of silence are not uncommon in the classroom. This allows students to become fully absorbed in an idea. and experience the joy of self–discovery, which has much more value than if someone tells them how to do it.
