If you REALLY want to implement flexible seating, but you also really want it to be more organized, this is the perfect product for you.
You can use this to create a rotating seating chart using your flexible seating options, while also allowing students to have a more flexible learning environment. This makes things much easier for substitutes when they enter your flexible seating classroom as well.
I use this by projecting it onto my board each morning to remind students where they are sitting that day. You can also print it onto a poster, or just keep it as a seating chart for yourself.
