I've coordinated a couple of trips to the campground with large groups of kids and chaperones. One of the trips we had the kids broken up into groups according to their cabins (you can do the same with your children) and each group had their own "mascot". We then printed out pictures of their mascots and placed one of each at each riddle location. If they collected all of their "mascot flags", it was verification they solved all of the riddles.
