The first day of school is always so nerve-wracking for our little ones. At our "Meet and Greet" night a couple days before the first day of school, I hand out these My Me Bags. They are for students to fill and bring back on the first day, to share about themselves.
We space these sharing times out over the first couple of days, so its fine that some students don't show up until that first day. They just share when they return their bag.
