The blocks were in tubs on the shelf in the center of the room. It was time for a change, so the blocks were put onto the shelf by the OHP, providing a more enclosed space for the children to build with the blocks. One of the children spent time building a structure. After he has finished, he was able to leave it there for a while, and later in the day he was able to put the blocks back on the shelf where he had found them. Changing spaces creates new opportunities.
