Drawing Techniques-Class or group setting

A fun activity in a group setting is to have  large banner paper, split up in several groups of 2-3 people who will draw on each sheet.  After a few minutes have 1 person from each group move to another group and continue drawing for the same amount of time and keep rotating until everyone has drawn at each group.  This teaches people to tie things together and is very fascinating to see different styles on a sheet.
