A lot of families have fun first-day-of-school traditions; my cousin's family has a cute end of school tradition as well.
They take a picture of their daughter stepping over the threshold of the classroom of each elementary grade. That way they capture the very last moment of "kindergartenhood" etc.
As she stands at the threshold, my aunt says something like. "This is the last moment of your being a kindergartner. When you step through that door you'll be first grader. Are you ready?...One...two...three- step through!" (Hugs and excitement!) "Now you're a first grader!"
Isn't that fun?
Does your family have any fun traditions/ activities you do on the last day of school? I'd love to hear about them!
