This is an excellent technology based activity for demonstrating setting in "The Sniper".
Students need to log on to google maps and find Dublin, Ireland on the map. Using the instructions listed, they proceed to explore what Dublin looks like using Google Maps and also research the Irish Civil War in which this story is based.
Students can work alone or in pairs, depending on the technology capabilities of your school. I use this in my grade ten English class during the short story unit.
