The yearly calendar shows a number of 'workshop' days. We feel strongly that the work on the shelves should be kept fresh and exciting and should reflect the interests of the children in the classroom that year. Every month, the staff removes all the work, washes everything and re-sets every tray, incorporating seasonal and unit studies that are appropriate. If there is a vacation at the end of the month, the workshop day is scheduled during that vacation. Otherwise, we close the school for one day toward the end of the month to put out all the new work.
