Students carry their chairs from the green, direct instruction, area to their tables, and back, depending upon our needs. When the chairs are in the table positions, we have a large central area that may be used as a floor work space or reading area.
The green area includes a "stage", created by removing the lower sections of the legs from a table. The table has been carpeted with the same material and pattern that covers our floor.
For students who would like to work while standing, they may move (at appropriate times) to the taller demonstration table.
I have discovered that this floor plan gives us a great deal of flexibility in our instruction, cooperative teamwork, and student choice.
