1st - 5th Chart
Each class has it's own seating chart and each seating chart is stapled to the front of a color coded file folder. EX: All kindergarten charts are mounted on purple file folders. (I'll take pictures of these during pre-planning.)
Last year I made color copies of my seating charts on card stock and had them laminated at Office Max. You could laminate them at school but I wanted the heavy lamination so that these would hold up for a few years. I use vis-a-vis markers to write on the lamination so that I can easily change things as the year progresses.
