Here's my idea: (taken from a popular FHE game using big candy bars) In order to accommodate my desire to sing, sing, sing, AND keep the children interested, i decided that i am going to have one class at a time come to the front where i'll have a long table set up with utensils and gloves for each child. They'll also have a bowl of hershey kisses in front of them. The rest of the primary will act as the "timer" and sing a christmas song. Those up front will have the duration of the song to unwrap as many kisses as they can with gloves on and using the utensils. (i plan on making this harder for the older kids with big gloves and allowing the sunbeams to do it without gloves). They have to unwrap the kiss, and throw the trash away with their utensils before they can get another kiss. Of course, they can keep whatever they open. Even if they don't open one, they'll get a chocolate kiss for participating.
I'll rotate through, having each class get a turn (as long as they are reverent and are singing when it's not their turn to unwrap). I think this will allow us to sing lots of songs and keep the primary involved. I'm hoping anyway!!! :)
