The numbers 1 through 31 atop two hearts. The hearts measure 2 inches square. There are also 5 blank hearts so that special days such as holiday, birthday, or no school can be written on them. These can be used during the winter season for calendar numbers or for a Valentine themed activity in a math center.
If you like these hearts, you might also like my other calendar designs. Check out my Christmas trees, candy canes, 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.
