Beautiful GhostGive each of your children paper and let them create their own ghost. Put the children's face on the ghosts with the heading "We are bootiful"
HalloweenSpread spice webs (cotton stretched, fish line, or other things you can buy at the store) webbing material over the entire bulletin board. Let the children draw their own spiders and hang them from the webbing.
Friendly ScarecrowOn your board create a large scarecrow (with hay or grass sticking out). Then give each of your children a precut bird shape. Let them decorate their bird however they want. Then put all of their crows around the scarecrow.
Ghostly FeetLet each child put their foot in white paint and make their footprint upside down on a piece of black paper. Draw a face on the heel of the foot. Enjoy these ghostly feet.
