Tip: I found a quick and easy way to collect and hand out projects with ease. I ask each table to put their art work in a pile in the center of their table at the end of class. When I collect the projects, I place them criss-cross.
Handing work back is easy too... because the kids all have assigned seats, I call one person's name from a table and they take the whole bunch back to hand out to their table mates. Quick and easy!
