The numbers 1 through 31 atop a blue Christmas ornament. The ball measures 2 inches square. There are also 5 blank ornaments so that special days such as holiday, birthday, or no school can be written on them. These can be used during the holiday season for calendar numbers or for a Christmas themed activity in a math center.
If you like these Christmas ornaments, you might also like my other calendar designs. Check out my Christmas trees, wreaths, leaves, sailboats, pumpkins, shamrocks, and more. If there is a certain shape you are looking for or you need a different size for your calendar, let me know and I'll be happy to put something together for you.
