Turn your classroom into a prehistoric land with
 this cooperative bulletin board mural. 

Background:
Divide a long piece of butcher paper into land and sky areas.
  The children can paint these areas with large house painting
 brushes or small rollers.  The children can dip cotton balls
 in glue and attach them in large clusters to make clouds.

Trees:
Cut brown wrapping paper or grocery bags into strips.  Have the children
 to twist them to make vines and tree trunks.  Staple to the background.
  Trace simple oval leaves onto different shades of green
construction paper for children to cut out and add to the mural.

Dinosaurs:
Give the children large precut dinosaur shapes.  Have them paint the
 dinosaurs at the easel one day, finger paint or sponge paint them
 another day, and coat them with liquid starch and cover with squares of tissue
 paper for a scaly appearance another day.  Add the dinosaurs to your mural.

After painting the bottoms of children's feet, Have them walk all over a large
 sheet of paper. Once it's dry, Write the caption " Kidasaurus Tracks"
 on top of the paper. Write children's names near their footprints
 like "Bobbyasaurus" or "Sallyasaurus"
