I have always struggled with trying to figure out some Halloween related games and activities for my preschool class -- this was before Pinterest really took off -- but last year I came up with the idea of making some different mouths, and shapes for eyes and noses that the children could stick to a pumpkin shape. As always, they didn't use the shapes as I imagined in my mind -- or like my adult brain put them together -- and they came up with some fantastic Jack-o'-Lantern faces that I could never have even dreamed up myself. That's one of the things that I like best about working with children.
I used mac-tac -- or a laminator -- to protect the pumpkins and the face pieces from wear-and-tear, and sticky-tack to make it easier for the kids to stick the pieces down and remove them too.
*Please forgive me! This was one of those moment when I needed to use my camera phone because I was working on this project at work. It also happened to be during quiet time so the lights were all out...please don't tell my boss :)
