Let's see:
Coffee Cart Opening Day, Open house refreshments and Scaveneger Hunt, Class picture for each child, Fall Festival, Family Craft Night, Books for every child on Block Party Night, Monthly guessing contests, Read Across America Week, Family Hoe down Night, Family Sock Hop Night, Holiday Diversity Night, Kindergarten Registration Gifts, Secretary Gifts, Staff Apprecaition Week, Positive Behavior School Store Rewards and Special Days, Grandparent Luncheon, Movie Night, Family Reading Night, any supplies for our own use (paper, etc), Pizza Party for Staff/Parent Volleyball night, Storytelling awards, Community task Force booth, Family Reading Night, Game Day.
That is a start, I think it truly depends on what the belief or mission of your group is, there are groups that raise 100,000's of thousands of dollars and it all goes to books, cleaning supplies, computers, etc. That is where they see the money needed, I consider my group very forunate that it was started by a principal who wanted that money to spent on fun things for our students and families, we don't charge for anything we do.
If you feel really uncomfortable bring it up to do something fun, express that family word. For the record out old PTA did a great job funding supplies for the school, we are the opposite big time!
