put up 3 landscapes for the students to look at. They differed in land form, time of day, and overall style. discuss how a color scheme can affect the feel of a work of art. Each student 3 post it notes, have them write one word for each picture, stuck them up over the pictures. ( I banned "good", "pretty" and "nice"), as well as the variety of descriptive words for each painting. It very quickly gave me a chance to fit a little writing in, and let everyone be involved in the critique.
