For a fun birthday party activity make a treasure map by either writing clues that lead them to different treasures or draw a map. Hide treasures around the house, the yard, or wherever you are hosting the party. The treasures they find can be as simple as lollipop, bubble gum, fun pencils, swords, rings, make up, fake nails, cars, etc. The children can be divided in groups of two or three or go individually to search for the treasures (party favors).
