The numbers 1 through 31 atop a football. The football measures 2 inches square. There are also 5 blank footballs so that special days such as holiday, birthday, or no school can be written on them. These can be used during the fall for calendar numbers or for a sports themed activity in a math center.
If you like these footballs, you might also like my other calendar designs. Check out my soccer balls, 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.
