While my desks are in groups, this is the chart she gave me to use:
The desk groups (with chairs) are on the master. Sticky notes are cut to the size of the "desks" in pink and blue colors to indicate genders. I write the first names on the sticky, then stick the note on the sheet "desk." I can pull them up easily to rearrange. Once I have a seating arrangement I like, I slip the whole paper with sticky notes into a page protector so they are visible but won't get pulled off by accident. Then, I keep all my seating charts on a clipboard, so they are easy to find.
I used to dread new seating charts, but this format makes it so easy. I rearrange groups and seating much more often now.
Hurray for smart young colleagues who still teach this old dog new tricks!
