My kindergartner came home with a request, indicating rewards for participation and most money raised, etc. I feel she is way too young,especially since she doesn't know why she is collecting money or how it will be used or the benefit to the school.
The notion that rewards for participating and raising the most money are being dangled in front of kindergartners is revolting and shameless. Taking your young child on a walkathon to help fund research to cure cystic fibrosis in kids can be explained to her and she can feel good about participating. What you describe her school asking of her does not remotely fall in this category. Schools can always say they need more money - this is not a way to go about it. I would see if you could get some other parents with similar views to present your collective opinion (and perhaps alternative fund-raising proposals) to the school administration.
