I was in charge of Bailey's Fall Party at school this year. Thankfully I had my mom to run to and ask for help. She helped me come up with these ideas:
To eat we had:
bottled water, pudding cups & graham cracker sticks, cheese sticks, cookies, cupcakes, and Carmel apples. (I had to make a emergency run for the water and cupcakes for they never made it to the party: what a nightmare)
For games we had:
Hot Pumpkin, throw beanbags into pumpkins, Fall bingo and throw rings around pumpkins. If you won then you got a prize (we made sure all the kids got prizes)
The kids all got into groups of 4 and did the games then made Fall hats and then ate all the good food before it was time to go home. I was ready to go home 5 mins into the party but was able to last the entire time. I don't know how teachers do it. Here are the pictures from the party. I think they all had fun I know I did.
All the yummy food.
