Hi Julie, I teach in the same type of setting. I have a "blah" classroom so I put my students into groups and have them draw key components in cartoon style on flip chart paper (I have a big bag of wide tipped colored markers). I post these around the room (they have an adhesive on the back) so I can refer to them through out the class. I take the papers down and save them until the next class. I use these papers until we have covered the topic. Then we make new ones and use them. This way we have activity, color and reference in our classroom and I don't have to worry about another instructor being upset with how I left the classroom. I don't do this every class meeting because this format doesn't fit every class but I do use it frequently to reinforce the students learning and give color to the setting. Gary
