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