I am totally doing a countdown to summer with all the letters and activities that go with . . . are you? This is a great resource and EDITABLE. Love That! Live, Love, Laugh Everyday in Kindergarten: ABC Countdown to Summer!!
Graduation (Pre-K and/or K) I would maybe have the student tell me what he/she wanted to be when they grow up to put on here for a cute memory and/or if the student had a favorite memory of the school year.
