100th day of school

Brief question below this post for people who've used formula.

I apologize for making this all about Kindergarten so far this week, but I really wa nt to talk about this 100th day of school thing. Do the Kindergartens in your area make a big deal out of the 100th day? It never happened when I was a kid, but it's a big deal at my son's school and other schools in NYC. The kids had to do a project containing 100 things (not containing food) and bring it in to school on the 100th day.

My son chose his own project, which was drawing 100 pictures. He's crazy for drawing (explosions, cars, and robots are his favorite subjects) so it wasn't a huge undertaking for us to put together a portfolio of 100 drawings.

One of the girls in his class did a gorgeous necklace make out of yarn with ten pieces of yarn hanging off the "chain," and ten beads on each hanging piece.

I didn't get to see most of the rest of the projects.

Did anyone else have to do this? Want to share some ideas, so people can get help if they're stumped? And how did this get to be a big deal?
