The numbers 1 through 31 atop a baseball bat. The bat measures 2 inches square. There are also 5 blank bats 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 baseball bats, you might also like my other calendar designs. Check out my footballs, ballet shoes, basketballs, 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.
