Second Grade Architecture

Mrs. Moyer's second grade artists were studying architecture. I already had three other second garde classes create painted houses using the elements of architecture that we had learned about. I was ready for a change. I had seen this lesson on the web and thought it might be fun to try out, I really liked the line characteristics.
The second grade studies suburban, urban and rural so we incorporated that into our lesson. The lines were created with pieces of cardboard. The background was made with tissue paper. The artist's really liked the way the color mixed when they glued the tissue down. I wish I could remember where is found this lesson- it is cool.
