Looking for a silent auction item that is extremely popular and easy to come by? A Saturday Babysitting Day provided by two or three teachers is always a hit.
Talk to the administration and OK the use of a classroom or gym at the school for a few hours of group babysitting. Their kids will have fun seeing the teachers outside of school hours. The parents already know and trust the teachers. The parents get the free time knowing that their kids are in a safe environment. And the fundraiser reaps the rewards.
Have the teachers recruit a couple older students or local teenagers to help for the afternoon. This will provide a great introduction between the older students and parents, as well as a built in recommendation from the teachers, expanding the babysitting network for future dates and make the day that much easier for your teacher volunteers. A win-win silent auction item for all!
