I made some Christmas Math worksheets and a game to go along with some of our Christmas themed school activities. You're welcome to print and use it with your little one! You can print it from here.
Wreath Decorating Game
For the wreath decorating game I included a page with a big wreath. My idea is to print and laminate it, then have Xander draw a random number tile (included) and add the corresponding number of "berries". You could use gems, beads, pom poms, play dough, etc.
