We give everyone a red ticket upon entering our events (We also post this on the flier to the event as a reminder to them.) We keep them in an empty pretzel/cheeseball container which is brought to EVERY event. Each participant is asked to put their name and a child's room number on their ticket. After the last event of the school year, a ticket or tickets are pulled. They win a gift card. As an organization everyone votes on where the gift cards are to and how much money will be on it/them. e.g. one card to Toys R'Us for $50 or two to somewhere else or you can split it however you'd like. The money figure and how many depend on how much your organization has to spend or would like to spend on them. I hope this helps. Good Luck in your new position.
