In our experience, nothing leads to lapses of safety faster than constant repetition and boredom. Camp and program directors need to be constantly on the lookout for new ways to keep their wranglers challenged and interested. We found various and fun ways to introduce parts of the safety orientation. We always try to remember the children's attention span, but we often forget the wrangler's and instructor's attention span which at times may be no longer than that of the campers. When minds wander it is time to reduce the risk level and go do something safe and fun.
Most camps have games that can be varied from week to week.
Many old standbys will work for all ages with a few variations. As long as the game is safe and there is a prize, most any game will work. The time spent on making up games during training at the beginning of summer will go a long way to preventing mental fatigue later in the summer. Planning is what prevents burnout. And it is far better to prevent burnout than to have to deal with it.
