Work on Writing. Samples of what students can work on include: Letter writing List making Story writing Start a Topic book (a book all about topic of student's choice) Comic strips Card making. All materials available for students at one location.
This is a fabulous way to get your students to familiarize themselves with all the different areas in the classroom. Also a great first day of school (wasting time bc you're finished with the rules) idea. For Pre-K I would use pictures with words.
