Designate a bulletin board or wall space to hang samples of preschoolers' learning center art and writing work. Label each item with the name of the child and the center where the work was done. Tape the papers to the board or wall.
On a sheet of writing paper, compose a paragraph or two about the activities children did in centers to produce the work. Hang the description with the children's papers.
Show the children the display. Read your synopsis to them. Refer to the display and discuss the children's memories of the experiences that led to the work.
With a digital camera, snap photos of preschoolers participating in center time activities. Print the photos. Glue each photo to the top half of a sheet of 9 by 12-inch construction paper, leaving room to write a caption underneath.
Write a descriptive caption beneath each photo. Include details in the captions -- children's first names, the center where the photo was taken and the purpose of the pictured activity.
Hang the captioned photos on a wall near the center where each picture was taken. As new captioned photos are ready to hang, remove the previously displayed pictures.
Use a three-hole punch to punch holes in the left side of captioned pictures when they are removed from the wall. Place them in a three-ring binder. Store binders of captioned pictures on a shelf in the center where the photos were taken. Encourage preschoolers to view the binder periodically to recall center time memories.
