Our school did a AR western theme last year. It was a lot of fun. Some classes used bandanas for curtains on the windows. The Principal's office became the Sheriff's office and the VP became the Deputy. You can get the heavy cardboard and turn you classroom door into a barn. Use rope for bulliten board boarders. Put a campfire in your reading center. Easy to do with brown paper rolled up for logs and some gray stones circling around to hold it all together. I had several cowboy hats in the room for the line leader to wear. A bulliten board theme.... Lasso a good book... with a cowboy and a rope lasso with book covers in the lasso circle. Red and white checked cloth (like a picnic tablecloth) looks good as bulliten board cover. Or try newspaper for the background with black boarder and black letters. "WANTED... GOOD BEHAVIN' STUDENTS"
