There is precision in the placement of the equipment and the accessibility for the child. The parts of a job are placed together, they can be taken once introduced and there is an expectation that when finished with they will go back pretty much where they came from. The order contained and maintained has the secondary role of aiding the child in developing an internal order. The pattern and order of taking a job, doing it and then putting it back, help the child develop a work pattern, an approach to a job in order to make it manageable. Within this prepared environment there are also aspects that are less visible, less concrete and less obvious.
Language is given after the experience.
The limits are given in a series of lessons called grace and courtesy . These include how to walk around the room without disruption, how to interrupt, how to ask for something and, my favourite, how to blow your nose. Part of the prepared environment is the concept of the three-hour work cycle. This time allows the child to choose some work and gain a level of concentration, then have a time in-between and then another choice of work bringing about a deeper level of concentration. For this to happen, time is needed.
