You'll need a ping pong ball and a cardboard box lid - a shirt box is fine. Cut a hole in the center and tape a paper cup under the hole - this will be the target for the ball. Other holes that the ball could drop through should be cut as hazards. Decorate according to holiday with crayons, markers, construction paper, etc. For instance, on Halloween make it a jack-o-lantern. Cut out holes for eyes and mouth large enough for the ball to fall through. To play, drop the ping pong ball into corner of box and have child maneuver box lid trying to get ball in paper cup without letting it fall through any of the other holes. The person with faster time wins!
