Toilet paper toss was very popular with the older kids when we were K-5. The pres's dad made it. It is pretty easy to store and the pattern seemed simple.

used to have some pretty good games. I wished I could think of that other page I had marked before the crash.
I'd love to have Plinko. We are planning to do a winter festival in Feb. if the powers that be approve. We are a 5/6 school. I think the kids would like that. Another thing I have in mind is having a "Wildcat Shop." Having spirit items along with fun school supplies that the kids can browse and buy.
Here are some other things I can think of:
*When I was in high school we had spring flings. I think different clubs had different things. One was a palm reading booth. We thought that was a hoot.
*Pie throwing contest? Don't know how expensive that is. You could sell chances for them to win a pie to throw at a favorite teacher.
*One year at the elementary we had hula lessons. It was for a Hawiaan themed Spring Fling but you could do it for pilates, yoga, or Bollywood dancing (I would pay .25 for a short session of that!).
*Characture painting. Not sure what that is called. It is when someone paints your face really big with a small body. Perhaps you have an art teacher or talented parent that could do that.
*Guess how many. When is your carnival? If it is close to Thanksgiving you could put cranberries in a jar and have the students to guess how many are in there. Holly berries around Christmas, etc.
*We have a card making machine at the elementary but you could do this with posters too. The kids like to get cards made with different slogans like "Best Friends" or something catchy. They even had fake DLs one year.
*One year we did our prize walk during the day for beanie babies. The older kids like that too.
