As part of a very small PSA, I’d like to run a small event at our primary school around Christmas, partly because it feels a nice thing to do and partly to raise some money for the school. The problem is we really struggle for helpers so need a few activities that bring fun to lots of kids but ideally only need minimal people. We’ve had success with treasure hunts that kids can do with their parents but don’t need people except to set-up, for example. But I can’t think of anything else like this! Has anyone got any advice?
