The kids are 7, and not knowing them very well I wasn't sure how scary we could go, so we decided to be pretty tame.
The boys and I had carved their pumpkins so they would be on the steps when the guests arrived. I knew that having 9 kids in the house would be pretty crazy, so I planned some structure activities in hopes of keeping them somewhat calm (hahaha - that was wishful thinking - it was a crazy evening).
I picked up some foam craft sets for the kids to make; I also had some supplies on hand for them to make ghosts (white paper plate, white streamers. construction paper shapes for eyes, nose and mouth, and white glue).
When the crafts were done, we had some snacks (witches brew, mummy juice boxes, fruit, pretzels and a crazy cake in the shape of a pumpkin)
I picked up "pin the smile on the skeleton" and had it taped to the wall to play.
I found a great printable Halloween BINGO game as well. I printed out the boards, cut the shapes and Mr. K was the BINGO caller for the evening while Mr. J and his friends played along.
As the kids were leaving, they each got a small goodie bag with a spooky plastic ring (spider, bat, witch) 2 rocket candies and a glow necklace to use when they are trick or treating on halloween night!
