Christmas Eve gift box (they get to open it on Christmas Eve)! They get new pjs (to wear that night), a Christmas movie, hot chocolate, snacks for the movie, etc. We already do pjs and slippers as our Christmas Eve gift but this is even better!
PreK Christmas/Winter: Snowman Names - Another idea would be to use the circles or "snow balls" to measure how many snow balls tall you are. Everyone in the class could be measured. Cute Winter Craft for preschool!
