Clifford the big red dog series has many books including major holidays and teaching students about alphabet and numbers. The classrooms that I observed had these books. Bridwell, N. Clifford the Big Red Dog. New York: Scholastic.
I remember there being a tether ball on the playground of my elementary school. I was the champ, being tall and competitive. My kids have tether ball at their school, too. I'm still better than all the kids, LOL.
