You could also go with the meeting idea but ask a question having to do with the meeting itself. A question having to do with something that you discussed at the last meeting! Hope this helps!
you could do a quetion concerning your last PTO meeting. Like during the meting, throw out some peice of trivia and tell them that will be the next question, then have a drawing of all the replies. this might help increase meeting attendance and add a little fun to the mix.
I had a brainstorm on having a monthly contest posted on the PTO Bulletin Board to encourage parents to read it. I have already aquired 9 donated gifts to give away, but I am at a lost on what kind of contest to have. Should it be trivia, and if so what type of trivia questions. I'm at a loss. Any suggestions?
