For my kids’ holiday parties at school, I always provided this game.
Prep: Get enough small trinkets to have one for each child….and lots of wrapping paper.
Start by wrapping one gift. Then add another item and wrap again. Continue till all gifts are wrapped into the layers. Hint: start with the smallest gift, to conserve paper. At the party, Play hot potato with the kids: Sit them in a circle and start some music, kids pass the gift around the circle, when the music stops. That child gets to unwrap a layer and collect the gift! That child leaves the game and you play on until everyone gets a gift. Fun, and believe it or not, some kids just never get to unwrap gifts at home.
