This year, I created some Pi Day cards to give to my students and made some Pi cheese bread and pizza.
I always stand outside my door when kids are walking by in the morning. Instead of just saying good morning, I greeted them with these cards. The kids got a kick out of it. I even saw some kids "re-gifting" the cards later in the day.
Homemade pizza and cheese bread is always a hit at our house. Here is the recipe for the dough:

I use the same dough for my pizza crust.
