I spray paint small rocks gold and hide them on the playground on St Patrick's Day. Some are almost in plain sight but some are hidden so well, they continue to find them for weeks. They can take them home in snack size ziplock bags. Cut a shamrock out of construction paper. While others cover their eyes, IT hides the shamrock within a designated area.
All players open eyes and try to find the shamrock.
The finder gets to be IT next. Before the children arrive, stamp the floor of the room with mini footprints made from a foot-shaped sponge that has been dipped in talcum powder. I like to leave a window open a crack and sprinkle green glitter around the room. Tell about the pot of gold and hide one somewhere to be found as a culminating activity. They children are convinced the leprechaun lost his gold.
